About Marathon Des Sables

The Marathon Des Sables (MdS) is known as the toughest footrace on Earth. The distance covered is 243km's in the Sahara desert, run in 49 degrees Celsius heat while every athlete carries his or her own equipment, food etc. weighing in at around 9-13kg's.

This blog is aimed at telling my story. I will record my preparation for the MdS 2013 in detail in the hope that it will help my fellow runners.

KAEM Post-Race Report



“After gazing at the sky for some time, I came to the conclusion that such beauty had been reserved for remote and dangerous places, and that nature has good reasons for demanding special sacrifices for those who dare to contemplate it”
Richard E, Byrd, Alone (1938)




As promised here is my post-race report on the Kalahari Augrabies Extreme Marathon. Wow, what a learning curve! The adventure was amazing, every aspect of the race was filled with personal challenges, individual success and a great team spirit. My experience is contrary to how outsiders would interpret extreme adventure racing. At first glance an outsider would conclude that this is a highly individualistic activity and that it falls beyond team work. Nothing can be further from the truth. Although highly dependent upon an individual’s, physical endurance and mental strength it is the collaborative team dynamic that serves as the primary motivator that allows an individual to continue way beyond his or her obvious capability. Extreme adventure racers are motivated by a dual dynamic, on the one hand personal achievement and on the other hand personal satisfaction that stems from helping a fellow racer.
     
I think that the most obvious aspect learned is that extreme adventure racers lack the concept of “around”. There is no going around an obstacle, there is only going over, under or through it. For most of us who live in a world where avoidance (going around) seems to be the status quo this takes some getting used to, however, the transition is fairly easy and I abandoned the going around nonsense within the first hour of the race.

The second aspect I had to abandon was my incessant drive to know. Extreme adventure racing is about living in the moment, the now is the only thing that has any relevance. Once I grasped this my mind seemed to relax and the obstacles that came my way became much easier to manage. Unfortunately making the shift to the now took a little longer.


“The only true wisdom lives far from mankind, out in the great loneliness, and can be reached only through suffering”
Igjugarjuk, Caribou Eskimo Shaman


From, a more philosophical perspective, I grasped the true meaning of Extreme adventure racing, unfortunately only on day 6. I came to realize that I am unable to subdue the desert; I am incapable of bending nature to my will. Trying to bend such an extreme environment to my will became fraught with “failure”, it taxed me physically, mentally and emotionally and nearly cost me the race. On the morning of the 6th day, I submitted to the desert, I decided to live in harmony with her. She saw this and rewarded me at so many levels. I came to realise that you cannot run in the desert, you can only run with her. By listening to her, she will show you what to do when. In the early days I would fight the terrain, running where she showed me to walk, walk when she gave me some shade to rest and so forth. On day 6, I saw the terrain differently; I came to listen to it more intently, when it was too difficult to run, I walked, when the terrain became easier I would run. When the desert gave a stream or a farm dam, I would indulge myself and would soak up the beauty that she gave. This harmony was rewarded when I was able to run 34% faster than my overall race average over the 44km’s on day 6.

So, if you would ask me what I have learned from the time I spent running across the Kalahari Desert it would be (1) to live simply, (2) be in the now and (3) listen to the silent guidance that we so easily ignore. I felt a harmony and peace, a certain fulfilment that you can only find in the most difficult of circumstances. I became softer but not weaker, I came to understand that “around” is not an option but I did so in strength and not power.

The friends made in the desert, the bonds built and the relationships solidified transcended both gender and nationality. Somehow, language was no longer a barrier and we all got along irrespective of who or what we are outside of the desert. It was great to simply be a human being, uncontaminated by social status, material wealth or the facades that we hold so dear in life. There were no masks, no pretence and no undermining motives. We were all raw, exposed and everyone could see who you really were. It was beautiful; I saw goodness, kindness, love, respect and perseverance. It restored my hope in humanity, for if in such extreme and taxing circumstances so much beauty and kindness can emerge there must surely still be a spark of hope for our species. The question is how we take the desert to our respective nations.

During my seven days in the KAEM tribe I was honoured with the title “desert poet” and have decided to have this printed on all my running gear from now on. Thank you to all my fellow adventurers (both runners and crew) who made every moment of the KAEM 2012 so special.

What follows is as much detail as I could possibly put together without spoiling the experience for others, I hope this helps.

Day 2 started with a climb, at 1,38km’s we were at an altitude of 434m and by the time we reached 2,18km’s we had gained 137m’s (up to 571m over an 800m distance). A similar climb was repeated on day 3 when we climbed from an altitude of 417m’s to 488m’s (a 71m gain) in little over 340m’s. At times we had to use ropes to reach the top.

Day 4, our long run, saw us cross three mountain ranges resulting in a total altitude elevation gain of 922 meters.  

A total of 46 runners entered the KAEM but only 38 (83%) completed the run. The majority of the 8 runners that withdrew from the race were as a result of the heat resulting in dehydration issues. Two runners, Phil Waudby and Henda Salmeron had more serious injuries with Phil developing hernia issues and Henda developing a tear in her patella.

It was with sadness that I had to say goodbye to both of them (both friends prior to meeting at the KAEM) on the same day. It made the reality of the extremeness of the event crystal clear. It was, however, great to see both of them from time to time manning the various checkpoints along the way. Their encouragement and positive attitude provided the strength and drive for many of us that remained within the race.

Maximum Temperature during the Event:           51 deg Celsius
Minimum Temperature during the Event:            -1 deg Celsius

Day 1 was a 30km run that introduced us to the desert, river bed after river bed made it clear that this was going to be a sandy run. The test came, however, when we ended up in a sandy river bed, in a gorge, that lasted for 3,3 km’s. The heat was intense but bearable.

Day 2 was 38km’s and started with a climb. Our race book had a warning printed in bold: “Please be vary careful here of loosening any rocks that may tumble down upon people below you. If this does happen please shout a warning to the others below you. This section is very steep and great care must be taken”. The climb was intense but the satisfaction of reaching CP1 at the top was empowering. Unfortunately the day would turn out to be one of the most intense in this race. The temperatures soared to well over 45 degrees Celsius early on in the day and peaked at around 50 degrees Celsius. At some point my Garmin Fenix recorded a 51 degree Celsius. All of this took its toll, the climb, took Phil and Henda out of the race, while the remainder of the day took many more out of the race. Rehydration became a constant focus whom some were able to manage while others paid the price. I reached CP4 with chest pains and a racing heart rate. After 20 minutes my resting heart rate was still well over a 100 beats per minute (normal resting heart rate for me is 48 bpm). This concerned me and the medical personnel which saw me being held back for around 2-hours before I was allowed to continue. I had to rethink my race strategy to ensure that my heart rate remained more stable and control able in this severe heat environment, more about this later.     

Day 3 was once again a 30km run and as with day 2 had a real climb early on in the race. At times the climb was so steep it required the use of ropes to reach the top, but both the climb and reaching the top was spectacular. The view from the top was indescribable. As the day progressed it seemed to cool a little with a desert wind being welcomed by everyone.

Day 4/5 was on every one’s mind up to this point. The distance of 79km’s (my Garmin Fenix recorded this distance as 80km’s and not 79km’s) were no small feat at the best of times but in this environment and on this terrain it was clear that it was going to be a real challenge. The wind that started on day 3 continued throughout the night which meant that we set off in a cooler environment that on the previous days. The run was scenic to say the least, we crossed two mountain ranges with spectacular views, ran in river beds, gorges and some of the most beautiful scenery nature has to offer, and all of that before we reached CP4 at 33km’s. I reached CP4 at 14:09 after having started out at 07:00, it therefore took me 7 hours to cover 33km’s; the terrain was difficult at times but rewarding every step of the way. In context, I would normally run a 33km distance in around 3h20. The terrain combined with the fact that we covered around 100km’s during the previous three days doubled my running time per kilometre. I stopped at CP4, took care of my feet, ate something and took a brief soak to cool down in the ”pool”. It is amazing how easily a farm dam becomes a pool when you are out there.
    
The day ended with a river bed stretch that reached from CP8 to the end, a total distance of 13km’s. At three in the morning I briefly lost my sense of humour around CP9, but a little warmth, a lollypop and a pep talk got my mind back in the race and my body had to follow. Thanks to some really great people at CP9 the last 6km’s were done in good spirits. In every ultra-endurance race there comes a time when you will have to dig deep to find the strength and will to continue, for me it was around CP9. By this time I had covered around 173km’s over the past 4 days, in some of the most extreme environment on the planet, battling the terrain, the heat, the wind and most of all my own mind. It was somewhere between CP8 and CP9 that the personal daemons had to be fought and conquered. The voices of doubt, the fear of going into the unknown and the desire to be comfortable all had to be won. The pain, the tiredness and the mental and physical strain had to be controlled. It is only when you reach this point that you are able to see how strong you really are, but this never happens alone. Each and every one of us finds the support we need at such time in something, sometimes it is our fellow runners, other times it is the support staff, maybe a prayer, nature itself or something else, but we all find something to hold on to that takes us over the tipping point. This lasts only a moment, once over the crest all your physical and mental strength is renewed and what lies ahead becomes somewhat easier.

Day 5 was a rest day, but that did not mean that it was stress free. In all of our minds day 6 loomed, another ultra-marathon distance, this time a 44km stretch that would take us to our last day if we could get through it. The knowledge that in previous races, those that completed their long stage had a close to 100% chance of completing the entire race was what kept us upbeat. The day was spent resting, sleeping, chatting, laughing and swimming in the Orange River. What a day!

I had the privilege of meeting Meng Poh Ng who travelled from Singapore to support some of his employees who ran the KAEM, raising money for a hospital back home. We set off on day 6 together.

Day 6, the daunting 44km run went well. I ran from the start to CP1 with Meng, a most interesting individual. He had run the KAEM the year before and gave me a good run for my money, his fresh legs challenged me and I had to stay focused. The scenery was stunning as the km’s ticked by and by the time I reached 40km’s I could taste the end. When I crossed the finish line on day 6, it was the first time during this race that the end of the race felt obtainable, it was in reach.

Day 7 was only 24km’s long. I started off with the same strength and determination as on day 6, by the time I reached CP1 it dawned on me that this was the last few hours I had left in this wonderful place. I changed my focus from running to finish, to slowing down so that I could soak up every moment. There was happiness on the one hand, the reality of finishing the race, the ability to hear Tanya and Arielle’s voices and the privilege of going home to the comforts that we are all so used to. But there was also some sadness, friends will have to part for now, the beauty and rawness of this wonderful place will have to stay behind, but most of all I will have to leave something very important behind, a little of me. I love the challenge, the ability to be totally exposed before the awesomeness of nature, the tiredness, the pain and the simplicity.

I crossed the finish line amongst new found friends all of whom had experienced the same hardship but stayed to taste the victory. My hart went out for those who had to be withdrawn from the race but stayed to cheering us on. This is what great sportsmen and women are made off. It is with them that I will run again, we will at some time in the future run this race together and we will complete it together. I could hardly wait to get a signal on my cell phone to phone Tanya and Arielle.

There is only one word that can come close to defining this race: Magnificent!

As I am writing this from the comfort of my home, I realize how privileged I am to have participated in such a great adventure. Thank you to my family for your support and indulging me on this journey. It is a reality that our loved ones make as much sacrifices as we the runners do, they tolerate our endless hours of preparation, support us when we enter events that we are unable to adequately describe, including giving a real reason why we are doing it. The reality is – We don’t know why! They worry about us, continues to believe in us and cry with us when things go right as well as when they go wrong. Our families are our greatest crew, thank you Tanya and Arielle!

2.       Race Analytics
After the event I attempted to find a relationship between individual performance and a number of elements such as (1) age, (2) marathon time, and (3) years of running experience.  For the sake of analysis I grouped the field into the top 10%, the next 20%, the next 40%, the next 20% and finally the slowest 10%.

I mostly disregarded the top 10% group’s performance on the basis that they represents the genetically focused group that will perform because they have a genetic advantage and is not representative of the larger population. The remaining 90%’s analysis provided some interesting results.

There seems to be a well-established relationship between performance and the number of years a runner has been running. The fastest group, the next 20% (after the exclusion of the fastest 10%), has an average number of active running years that comes to 17. The next group (the average 40%) has an average of 11 years with the second slowest group averaging 9 years. The slowest group has an average of 7 years running experience.

Age seems to be somewhat spread over the field, although there appears to be a tendency for the fastest 10% and next fastest 20% group to have an average age of around 37 years. The Next 40% has an average age of 44 while the second slowest group averages 46 years. The slowest group has an average age of 42 years but I think this has less significance. And that running experience has a higher relevance.
 
Marathon time follows a similar pattern with the top 10% averaging a 2:49 marathon, the next 20% averaging a 3:12 marathon, the 40% group averages a 3:28 marathon while the second slowest group has an average marathon time of 3:47. The slowest group has an average marathon time of 3:38 which again, for me, points to running experience playing a far more consistent role in performance.

What was noteworthy from a running prediction perspective, however, is the relationship between marathon time and actual race performance. The fastest 10% took on average 69% longer than their marathon time to cover the same distance. The next 20% took 103% longer, the 40% group took 115% longer, and the second slowest 20% took 143% longer while the slowest group took 211% longer than their marathon time. I interpret this to point towards physical conditioning that comes through years of training, running experience and overall body conditioning. It seems clear to me that the longer you run consistently the better your overall performance would be.

I, therefore, conclude that an individual’s own race objectives should be pegged within the broader parameters. Years of running experience, your age and ultimately your preparation all plays an equally strong role in dictating what your performance will be during such an extreme event. There are, however, exceptions to the rule. In the top 10% we have such an anomaly. Firstly Alwyn Maas (2nd position) is much older than the average 37 years, but compensates for this through conditioning and his 13 years running experience. On the opposite side is Tiaan Erwee (3rd position), having only 4 years running experience he compensates through conditioning and his relatively young age (12 years younger than the average). I am also of the opinion that genetics has a much stronger role in this group’s performance than further down the field.

In conclusion, no single element on its own drives performance. Nor does a single element dictate an ultimate limit on performance. It is, therefore, ultimately how each runner balances his age, physical and mental preparation, and running experience that will dictate his overall performance. It does, however, seem highly unlikely from the available data that a runner would be able to enhance his performance through physical conditioning only.


3.       Personal Objectives
Entering the race I had four primary objectives, the first was to test my nutrition hypothesis. On all accounts this seems to have been highly successful with some minor changes that will be discussed later. My second objective was to assess my pack content and weight, I feel here I had the greatest of success as I will be making huge changes, at first this seems to indicate a weight reduction of around 1,7 to 2,2kg’s for the Marathon des Sables. I will discuss this in detail below. My third objective was to test my training program’s effectiveness. It seems as if my program is mostly adequate, however, I have identified two areas for improvement. My last objective was to complete the race in a time somewhere between 50 and 70 hours. At 59:39:00 I am happy with my performance. Without much change and with a little experience I could have easily shaved off an additional 5 to 7 hours of my time.

Overall I reached all my race objectives and more.

4.       Race Conditions


“It is not because things are difficult that we do not dare, it is because we do not dare that things are difficult”
Seneca (Roman Philosopher, 1st Century AD)


4.1   Heat
There is not much that can prepare you for the extreme heat that a desert race will throw your way. But it’s not just the heat that plays a role but the temperature swing that can be a huge shock to your system.

The effect of both is best demonstrated by two experiences I had during the race. The first was on day 2 when a 50 degree Celsius peak saw my body attempting to cool itself by increasing my heart rate. Unfortunately a rapid heart rate increases your overall metabolic rate which translates to higher calorie consumption as well as reaching a higher level of fatigue earlier than normal. Obviously none of these are any good during an extreme adventure race.

I had to find a way to manage my heart rate more efficiently throughout the race to prevent this from taking place. My solution for this was to (1) stay hydrated, (2) keep on fuelling my body and (3) run wisely. To do the latter meant intense concentration. You need to read your terrain constantly, be cognisant of your own physical effort and then adapt your running to maintain a constant effort opposed to a constant speed. This way I was able to maintain a relatively constant 140 BPM on average with a resting heart rate within 15 minutes of running of around 54 BPM. Although this meant a slower run for me, it effectively managed my risk, allowed me to stay in the race and gave me an opportunity to do what I set out to do. The result was that I maintained a cooler and more constant core temperature, maintained an average heart rate that was within 3% of the rate I used to calculate my nutritional requirements and less fatigue.

The second event happened at around 02:00am on day 5. During the long stage, at around 65km’s most of my energy was already depleted, and a sudden drop in ambient temperature to -1 degree Celsius caused me to rapidly cool down. Although the temperature had climbed again to the low 20’s by 03:00am my body was spiralling downwards and hypothermia started to set in. Uncontrollable shivering was once again consuming energy reserves that I did not have, also not a great position to find yourself in when you are crossing a desert. What gave rise to this was a bad decision earlier on in the race. I scheduled CP6 as my dinner CP, when I arrived at CP6 there were no warm water so I decided to push forward to CP7 another 8,5km’s away. Unfortunately by this time I was running on empty and reaching CP7 took some serious hard work. At CP7, I ate my dinner and rested for about 90 minutes. Unfortunately my earlier decision took my body to near depletion and the food I had for dinner could cover the immediate effects but there were insufficient time for my muscles to absorb and store the nutrients. By the time I reached CP8 refuelling consisted primarily of solving short term requirements so fast burning carbohydrates became the solution. The drawback of fast burning sugars is that it causes your energy levels to peak quickly followed by a crash, each time you repeat the cycle the effect gets worse. For me the crash combined with the environment came in the form of hypothermia.

The best would have been for me to have had my dinner at CP6 as I have planned, even if I had to have eaten it cold. Fuel is more important than taste in the hierarchy of desert survival. The best I could do to solve a single bad decision was to (1) take a rest, of about 30 minutes, (2) take out the survival (space) blanket to increase my core temperature and (3) refuel slowly, first with a feel good fast burning sugar in low quantity (a sucking sweet), then followed by a slow burning energy drink (32Gi), to sustain my energy reserves until I could refuel decently. This strategy worked but I will not suggest allowing yourself to deteriorate to such a point. Energy depletion should be avoided at all cost.            

4.2   Sun
The sun is relentless and with the decreased pace (due to the terrain) we all spent many hours subjected to the harsh desert sun. The best way to deal with the sun is to avoid burning altogether. For me this meant using Nivea’s SPF50+ for Kids, I would cover my body once in the morning before the race start and would not need to recover any area, irrespective of how much I sweat or dowsed myself at CP’s. I came home a little more tanned than before I left. This was one of my primary concerns before I left as I have a tendency to burn really badly when out in the sun.  

4.3   Sand
What can one say about the sand? Well firstly there is good sand, this is the sand that slows you down but you are still able to maintain a steady run/jog pace. Then there are the @#$% bad sand. This is the sand that slows you down to a walk and even makes a walk difficult to sustain. It requires great effort to move through and taxes you both physically and mentally.

There are a few things worthy to note about sand. The first is avoid it all together, unfortunately if you decide to run in a desert this is not possible, so then the next best thing to do is make peace with it. It will (2) get into everything, your shoes, your socks, between your toes, fingers, literally everywhere. Therefore, avoid, cream on your feet or between your legs. It will hold the sand and create a very efficient grinding past that will eat away all good skin and flesh. So in short keep yourself dry. Some runners allowed the water to run down into their shoes when dowsing themselves, the result was skin loss around the back and under the heel. As one can imagine this is an extremely painful condition, making running virtually impossible and extremely painful.

Running in sand requires a high knee lift motion and a predominantly toe strike. Unfortunately this combination works well for fast runners for who this seems to be a more natural running style. The slower runners, and those already tired seems to have a mid-foot strike that reduces one to walking. As a matter of fact, I found that a brisk walk on sand out performed my own efforts to run with added benefits of a lower energy consumption and lower core temperature. I also outperformed other slower and tired runners who tried to maintain a running pace. I came to the conclusion that walking is an essential skill for any extreme adventure racer, and one that is seriously neglected in most of our training.

4.4   Rocks
In the Kalahari these varied from small unstable rubble to boulders that need to be carefully climbed. At times, small rocks can make running near impossible with the risk of losing your footing and sustaining a serious injury so real that walking is the only viable option. The darker rocks, obviously retains the heat meaning that when running over these you have a dual heat source warming your feet. The result is an expansion or swelling of the feet and for this reason an oversize shoe is best. There is a thought that your feet will only expand width wise so a half size should be able to accommodate the expansion.

I can only base my conclusion on my own experience and that is that my feet expanded in all directions during the heat of the day. Firstly blood rushing to the extremities, and your heart’s inability to recall all the blood from these extremities results in gravity trapping blood in your feet. This accumulation is the first source of swelling or expansion. The second is the heat from both above and below which adds additional expansion in width, length and height. I wore two sizes bigger than my normal running shoes and at times I felt that my shoes were too tight. Wearing elastic lases meant that adjustment is fairly simple. The final source of swelling for which you need to make provision is for injury, both muscle based and blisters. Although I had none of these other runners (especially those with heel blisters) were quite happy that they took an oversize shoe.

I ran with a shoe, two sizes bigger than my normal size and will continue to do so in the future.   

4.5   Snakes, Scorpions and Spiders
In the area that we ran the dominant snake species are pufadder’s and black spitting cobras. A few runners encountered a spitting cobra just outside a CP, but I was unlucky in that throughout the seven days I could not find a single snake to photograph. The scorpions are relatively small and I had only the briefest of encounter with a scorpion when I sat down to clean the sand out of my shoes during my nigh run. A scorpion (about 100mm in size) walked over my hand. Fortunately I could flick it off.

Spiders on the other hand caused all manner of commotion amongst those in the group that were arachnophobic. These little critters “invaded” the tent one evening which caused many of the runners to have a very uneasy night.

Be that as it may, no serious venomous bites or stings were recorded during the event.  

4.6   Wild Life
The wildlife was spectacular, we were fortunate enough to see ostrich, giraffe, spring bok, and a host of other antelope, some dassies and meerkat. During the evening there were porcupine and on two occasions, day 3 and day 4 we found leopard tracks on top of our running tracks. This meant that a leopard had walked amongst us without being seen. Now that is an adventure. On occasion we saw some monkeys and baboons but the baboons were more regularly heard than seen, especially when we descended into gorges.


5.       Medical Issues

5.1   Dehydration
As can be expected dehydration is one of the foremost issues during a desert race. The advice I can give to anyone is to get into the habit of drinking continuously throughout your run. Alwyn Maass gave me a brilliant idea that worked; he takes one sip of energy drink and two sips of water at regular intervals. Effectively you need to time it that you drink your 1,5 litres of water between each CP and half of your energy drink (350ml) between each CP. This ensures that you remain fuelled and hydrated throughout.

I have two hydration tests that I use as markers. The first is the brow test. An oily brow is an indication of dehydration so I do this regularly throughout the race. The second test, that of the urine test is vital. Urinate regularly, and if you can’t see through your urine you are in trouble.         

I was fortunate enough that my preparation trained me to drink continuously so dehydration did not really affect me that much. Remember if you are thirsty, you have already started to dehydrate. Rehydration aids that are mixed with water can help to restore you quickly, although I personally found the taste to be so bad that avoidance became a priority. 

5.2   Blood Sugar
Blood sugar level will automatically fluctuate in such an extreme environment, especially, when the body is placed under such extreme stress. The key to stabilizing your blood sugar is to eat well and often. Testing your food prior to the event is essential. 

5.3   Blisters
To some extent, blisters are unavoidable, especially if you consider the running environment. Generally I don’t get blisters but developed three relatively minor blisters. I consider minor blisters as normal for such conditions. There are, however, some runners that developed really serious foot conditions. These ranged from toe nail issues to blisters. I could not find a magic formula for avoiding blisters and other foot conditions. There seems to have been as many runners with blisters that bind their feet then those who don’t. Again my own experience stood me in good stead, these included the following: (1) Miles, nothing prepares your feet like putting in the training miles. I did not use any creams, hardeners, or extreme conditioning techniques, just consistently running day after day in preparation. (2) Stay hydrated, (3) keep your feet dry and clean throughout by stopping and maintaining your feet regularly. For me this became a CP ritual and (4) finally do foot maintenance every day after you completed your day’s run. Treat the minor issues so that they don’t become major issues.  

5.4   Scrapes
As stated earlier, adventure racers goes under, over or through everything so scrapes, bruises and cuts are to be expected. Clean these with some antiseptic fluid and cream and a plaster if it is deep. Besides that role with the punches and take it on the chin. It is a good idea to have a tetanus injection before you participate.   

5.5   Fatigue
This is normal given the environment you are in and the stress you are placing on your body. A diet with sufficient calories and good hydration will deal with most of this. However, without a good night’s rest your body will remain fatigued and this will eventually have a huge psychological effect. I, therefore, recommend a light sleeping mat and a good sleeping bag that is rated to provide the comfort you need given the temperatures you are to expect during night times. As backup a light fleece will provide added warmth. A good meal and a good night’s rest will make all the difference when your body needs to recover for the next day’s pounding.   

5.6   Muscle Spasms & Cramps
The older and more experienced guys quickly taught me the trick of sucking on an anti-acid tablet. Sucking one or two Rennies or chewing an Eno tablet breaks down the acid in the body which prevents muscle spasms and cramps. I tested the Rennies and they worked.   

5.7   Medication
Medication is a real problem within an extreme environment where your fluid intake is restricted. Paracetamol and other analgesics could cause major kidney and liver damage if not used wisely. The best is to avoid medication throughout the event, however, if unavoidable, discuss this with the event doctor before taking anything. Rather safe than sorry.


6.       Water
Water is a really scares commodity that is firstly used for drinking, then food, then cleaning and lastly for laundry. Unfortunately there are seldom if any enough water left for laundry. Use your water sparingly; it is what makes the difference between having a good or a bad race. Create a natural fridge to cool your water somewhat. A one or two degree change makes all the difference when you are out there. Take with a few buffs, wet these and draw them over your bottles. The slightest breeze will cool the water inside the bottle.


7.       Race Equipment and Consumables

7.1   Food
Be realistic when it comes to your food. Choose foods with a high calorie to weight ratio as this will make your food weight as little as possible. Nutrition trumps taste but that said taste has a really great psychological effect so there is a fine balance to be maintained. Test you food beforehand, and I mean everything.

7.2   Clothes
I took two sets of clothes. The reality is that one set with additional underwear and socks would have done just fine with one fleece and a pair of flops for around the camp. Dumping the additional clothes would have saved an additional 500 to 600 grams. A small hand towel opposed to a larger towel would have saved even more.

7.3   Shoes
I ran with Nike Pegasus 28’s and no gaiters. For the Kalahari this is fine but I would really need to find a great gaiter solution for the Sahara. I will also be trying out the Solomon S-Lab 5 running shoe within the next few months. The guys running with these seemed to have far less and issues than the rest of us.

Another aspect I will be experimenting with is toe socks, covered by a thin second sock. The runners who ran with this combination had no toe blisters and as all my blisters were centred between my outside toes this might be a solution.  

7.4   Hygiene
I ran with two hand / face towels, one yellow and one red. Both attached to the outside of mu front pack. The yellow towel was for general use and was used for washing, drying and wiping the sweat away. The red towel was used for washing and wiping my hands after using heeding the calls from nature. 

7.5   First Aid
My first-aid kit was packed to the brim with enough of everything to conduct a small operation in the field. Needless to say I needed very little of what was in my pack. In the future my focus would be blister orientated only. 

7.6   Technology
In the future I would leave my IPOD as this was not even switched on once during the race. During my run I preferred to hear the sounds of nature and in the camp I loved the conversations that took place. As for my camera, there was one lens that I didn’t use at all as well as the second battery and flash was not used once. All of this will stay. I will also no longer take a battery pack with batteries as I would only need to charge my Garmin Fenix which can easily be done from a solar charger (power monkey). On the camera issue, it was the best thing I took with on the trip, I was able to bring back so many great memories, and the weight of a good camera was worth it.


8.       Food
My race pack weighed in at 14,5kg’s wet. Of this my food weighed in at 5,2kg’s, my water 1,5kg’s and the rest was clothes, first-aid kit etc. Therefore, of the 14,5kg’s around 46% constituted my food and water, both essential items in surviving the desert environment.

8.1   Calories
My energy requirements calculated to 25,769 KCal’s. I decided to follow the conventional wisdom and rely on fat reserves to supplement about 20% of my overall energy requirements. My total food supply came in at 21,483 KCal’s of which 2,288 KCal’s were protein powder. I brought back around 2,500 KCal’s, consisting mostly of protein powder and 100g’s of nuts. It would be safe to say that I easily survived on 18,983 KCal’s which is around 74% of my calculated energy requirement. I did no real carbo-loading prior to the race and had no periods of hunger throughout the event.

My energy levels remained fairly constant throughout the race and besides cold water didn’t really crave anything in specific.      

8.2   Sequence
I started to experiment with eating sequences during the race. One of the changes I made that delivered a huge benefit was to drink my Milo and condensed milk after breakfast and not after dinner. It delivered a huge energy boost early morning when I really needed to get through the day. The breakfast with Milo, and Condensed milk easily sustained me for the first two and a half to three hours each day.

Continuous eating throughout the day ensured that my muscle energy reserves did not become depleted, the exception, being day 4 (long run).

8.3   Other
I did learn a great deal from the other, and more experienced runners. I will add soup to my food pack and drink this as part of my dinner. Olive oil is a great source of energy and fat so this will be added in the future. David Ball brought with olives and had olive snacks along the way, this appeal to his taste and greatly lifted his spirit at times, so each person will have to take with that something that does more than just feed the body. Clint Seager told me how Nik-Naks chips got him through a difficult time during the 2011 KAEM, and as I also like Nik-Naks took with two packets. It felt like a party when I eventually opened my first pack of Nik-Naks on the rest day.

I will also take with three more packets of 32GI energy drinks and will take this at more regular intervals as suggested by Alwyn Maass.

I will be analysing a larger pool of data collected by various runners during the KAEM to see how the extreme heat impacts upon heart rate and ultimately upon the body’s energy requirements. This will be published once the analysis has been completed.


9.       Psychological Aspects
Then there are those elements that can make or break a run. I experienced how a good sense of humour can lighten the most difficult of circumstances. Interaction and communication within your running community, both before and during the race is in my opinion vital. The pre-race communication creates an open platform for idea exchange while the in-race communication creates an ability for you to contextualise your own performance, hardship and pain.

There is, however, a real need for an ultra-endurance runner to train him or herself to deal with prolonged periods of solitude. During any leg of the race you will find yourself amongst other runners one moment and then again alone the next. During your long run these periods my extend for hours.


10.   Training Changes
I have learned a great deal from this experience and in particular how well my training prepared me for the race. I feel that my weekly distance that averaged 80km’s per week and peaked at 120km’s were more than adequate given my race objectives. There were runners that averaged 50km’s per week who battled but still completed the race.

I will, therefore, not change my weekly distance by much. I will, however, work towards averaging 100km’s per week opposed to 80km’s, but this has less to do with pushing miles and more to do with what I feel I need to add. The additional km’s will be spent walking. If there is one thing that I was totally unprepared for, it was the amount of walking that we needed to do. At times the terrain would simply not allow you to run. To learn how to walk consistently and at a good pace is essential.

I will introduce more speed training, my present program had a speed week every 5 to 6 weeks, but I will now rather introduce a speed session every second week. I will also introduce three gym sessions per week to work on legs, arms, and my core.

I hope that this post-race report will assist many of you in preparing for your own extreme adventure race in line with your own objectives. If you have any questions or comments please feel free to share these.
