This page provides more information about nutrition. You can find information about do’s and don’ts for nutrition during a race explained by sports nutrition scientist Asker Jeukendrup (CORE Nutrition Planning). Further down the page you’ll find more information about the special deal CHALLENGEALMERE-AMSTERDAM can offer her participants to get a free personalized nutrition plan by CORE. Furthermore, you can download the Challenge Family Nutrition Guide here. At the bottom of the page you’ll find information about what kind of nutrition we hand out at our aid stations.

For a Middle distance triathlon or other 4 to 7 hour event, or for a Long distance triathlon which can last up to 17 hours, nutrition can be an incredibly important factor. In shorter distance triathlons you can get away with making some nutrition mistakes, but during a Long or Middle distance triathlon, it is more likely that you will be punished for nutrition errors. In fact, when you talk to athletes who did not have a good race, they will often mention nutrition as the main reason why things did no go as planned.
On this page the basics of nutrition are discussed: a few general rules of nutrition and some of the most common mistakes.
Three Main Nutrition Issues
The three most important nutritional issues during a Long or Middle distance triathlon are:
1 Meeting the man with the hammer
Running out of fuel, hitting the wall, bonking, or just not being able to keep up the intensity during the last part of the race.
Becoming progressively dehydrated to an extent where this will limit performance.
3 Stomach problems
Gastrointestinal problems such as stomach cramps, bloating, etc. that can have a negative impact on your performance.
The main fuel for an event like this is carbohydrate, especially if you are completing the race closer to the 4 hour mark than the 7 hour mark. Your body stores contain roughly 500 grams of carbohydrate (this is 2000 kcal), not enough to make it to the finish line. In theory it should be enough to get most athletes through the first 3 hours of a race but topping up from the start is essential. Because it takes time for carbohydrate to be absorbed, you need to start early with fueling to make sure you avoid carbohydrate depletion. Once you run out of carbohydrate stores it is difficult to recover.
As a general rule, aim for 60 grams of carbohydrate per hour (1,2). This carbohydrate can be in the form of a bar, a gel, chews, or a drink. If you use solid foods, make sure fat, protein and fiber content are low (no more than a few grams). What you use is entirely up to you and your personal preferences. Faster athletes tend to use more liquids and less solids because it can be difficult to chew at high intensities.
To give you some idea of what 60 grams per hour equates to, it means that for every hour of the race you would need one of the following combinations:
– 2 gels and a small amount of sports drink;
– 1 gel and a bottle of a sports drink;
– 1 energy bar and half a bottle of a sports drink.
For more accurate calculations check the food labels of the products you are going to use for exact amounts.
“Drinking to thirst” is a recommendation that works fine for the slower athlete. If you are going a bit faster it is better to go in with a plan. It is good to use the early parts of a race when the gastrointestinal tract is working fine to absorb both carbohydrate and fluid. Later in the race, even though you may be thirsty, the gut may not absorb as much. Don’t drink excessively and use common sense. The goal should be to lose a little weight (2 to 4 pounds) at the finish line. You definitely want to avoid weight gain, which clearly would be a s sign of drinking too much. In hot environments dehydration can definitely be a very important factor. Don’t forget that good hydration starts before the race, and hydrate well in the days leading to your race.
A large percentage of athletes, approximately 30 to 70 percent, experience gastrointestinal problems during Long and Middle distance triathlons. Some of these problems are very minor but some of these may be so severe that they will affect performance. Some athletes are more prone to develop these problems than others. The complaints may be totally independent of food intake and sometimes they may only happen on race day. This suggests that “race day anxiety” has something to do with it. Studies have also shown that factors like fibre intake, fat intake and the use of very concentrated carbohydrate drinks are causes of gastrointestinal discomfort. So combining these three main issues, you need to plan ahead and have a rough idea where you are going to get your carbohydrate from (drinks, gels, bars), how much fluid you need to take in and where you are going to get this from (carry, special needs for feed stations) and make sure you reach approximately 60 g/h of carbohydrate intake and enough fluid to not lose a lot of weight. You can get a good idea by weighing yourself before and after training. Think about this in advance and write down your plan.
Common mistakes on Race Day
The most common mistakes are:
1 Sticking to a plan at all costs
If for some unforeseen reason you cannot follow the plan (you lost a bottle, or you are developing gastrointestinal problems), do not continue with the plan at all costs. Be flexible and adapt. A slightly lower intake is not going to be a problem, forcing more nutrition in will.
2 Do not try something new on race day
Sometimes you’ll see athletes walk around on expos, buying new products for the race the next day. Only use products that you have tried and tested, products you know you tolerate well.
3 Thinking that more is better
Drinking more and eating more is not always better. Sure, you have to take in enough energy and enough fluids, but once you achieve the basic needs, more is not necessarily better and in some cases detrimental.
A couple of extra points:
1. Sodium losses in a race like this are unlikely to affect performance in the vast majority of athletes, so sodium supplementation should not be a priority. Too much might cause gastrointestinal problems.
2. Caffeine (low dose: 3mg/kg one hour before: equivalent of a big cup of coffee or 2 espressos before the start) may help some athletes. Some athletes like it, some don’t. Experiment in training and find out what works for you.
CORE’s nutrition plan & CHALLENGEALMERE-AMSTERDAM
As a participant of CHALLENGEALMERE-AMSTERDAM, you can receive a PREMIUM nutrition plan by CORE for FREE that is based on the nutrition you’ll receive during our race. This means that every gel, drink and other nutrition that we offer at our aid stations has been included in this program. CORE’s nutrition plan will tell you exactly what nutrition to get at what aid station on our courses so you can optimize your race results but also make sure that you don’t get too much or too little nutrition during the race.
Please note that it is very important to train with nutrition before you compete in a race. This way, your body gets used to the type of nutrition you take during training.

Every bike lap offers four aid stations located 22,5 kilometers apart.
Every station consists of two stalls, 20 meters apart. Nutrition is served in the following order:
1) Half bananas
2) PowerBar EnergyGel
3) Sport drink: PowerBar – Bottle 750ml
4) Water – bottle 750ml
On the run course, you’ll find four refreshment stations approximately 1,5 kilometers apart from each other. Nutrition is served in the following order:
1) PowerBar EnergyGel
2) Food: raisin bread, bananas, oranges
3) Sport drink: PowerBar – bottle – 750 ml
4) Cola – blue plastic cup
5) Water – blue plastic cup
The coach station for the bike course is located in the Havenkom in Almere Haven. It can be reached by bus (line M1 to Haven Centrum) and is clearly indicated with signs.
The first coach station on the run course is located on the Koetsierbaan. The second coach station on the run course is located on the Lesplaats, which can be reached by bus (line M1 to ‘t Oor) or by foot by following the run course.
The coach stations are clearly indicated with signs. Only within this area coaches are allowed to hand participants their own food and drinks.
Each aid station is equipped with a toilet, both on the bike and run courses.
Please note that you’re allowed to throw away your trash only in the 200 meters before and after an aid station. Do not litter the rest of the course with your garbage. In case you are spotted throwing away your materials – like cups, sponges, drink bottles or empty gels – elsewhere, you risk a penalty. This is in force for both the bike and the run course.
