01 · Energy and confidenceEnergy and confidence
Eating before a race is about three things: enough energy, a calm stomach and confidence in your routine. No matter how fit you are, if you show up at the start with half-empty glycogen stores or an upset stomach, it will cost you unnecessary time and energy. The days before the race are not a time for experimenting; you choose food that you tolerate well, that you have used before and that you know you run well on.
A smart nutrition plan prevents hunger pangs, energy crashes and stomach complaints. By building your meals step by step — from the days before the race to the hours just before — you create a stable fuel base that allows your body to reach peak performance. Think of carbohydrate stacking, light and low-fiber meals on the last day and small, quick snacks in the hours before the start.
Hydration is the silent force here. You can eat perfectly, but without enough fluid and electrolytes your engine will still stall. Therefore, also check your drinking strategy. You can read more about this in Hydration during hot runs — ideal when it is hot or if you are prone to sweating a lot.
With a well-thought-out food and drink plan, you can step up to the starting line with calm, confidence and a full tank.
02 · The 3-day nutrition planThe 3-day nutrition plan
Days before
Last evening
Race morning
A good competition performance does not start on the competition day itself, but in the days before. Your body needs time to build up glycogen stores, soothe your intestines and optimize your fluid balance. This 3-day plan ensures a stable energy supply, prevents stomach complaints and helps you arrive at the start with a light, but fully filled tank.
The key is familiar foods, plenty of carbohydrates and less fiber and fat as race day approaches. This way you reduce the risk of belly rub and maximize your energy. Use this schedule as a guideline and tailor it to your own experience and test moments during training.
| Moment | What to do | Examples |
|---|---|---|
| 3–4 days in advance | Increase carbohydrates to 55–65% of your energy intake. Keep training light to build glycogen. | Whole wheat pasta, rice, bread, fruit, muesli |
| 2 days in advance | Keep the same balance and focus on extra hydration. Avoid heavy strength training to keep muscles fresh. | Sweet potato, wraps, bananas, yogurt |
| Last evening | Choose an easily digestible meal, low in fat and fiber to give your intestines a rest. | Rice with chicken and carrots, couscous with chicken fillet, white bread with jam |
| Match Morning | Have breakfast 2–3 hours before the start with food that you have already tested during training. | Oatmeal with honey, bagel with banana, bread with jam |
| 30 minutes before start | A small quick energy boost to completely replenish your glycogen. | Half banana, gel, rice waffle |
With this approach you will not only be well fed, but also confident and prepared for your race.
03 · The days before the competitionThe days before the competition
The last days before a competition are crucial: you no longer build up fitness, but ensure that your energy reserves are fully filled, your intestines relax and your body is fresh at the start. Now is the time to simplify nutrition, optimize hydration and only do light workouts. Think of these days as refining your preparation — small choices here make a big difference on race day.

On the day itself it's all about rest, routine and timing. You've already done the work — now make sure nutrition and hydration support your performance, not hinder it.
Also think about your recovery after the finish. Recovery nutrition: best snacks and drinks after your workout helps you make the most of the first hour.
05 · What better not to do?What better not to do?
The days before a competition are not the time to experiment. You want to keep your intestines, energy levels and nervous system as predictable as possible. It is therefore better to avoid anything that poses a risk of stomach complaints, energy peaks or unexpected reactions.
06 · MistakesCommon mistakes
Many problems on race day are not caused by a lack of fitness, but by nutrition and hydration that are just not right. You can train perfectly for weeks, but one wrong choice on the morning of the race can ruin your entire race. By knowing which mistakes occur most often, you can avoid surprises and approach the start with more confidence.
Eating too late. On race day → food is still in your stomach at the start. This leads to stitches, a feeling of heaviness or even nausea. Make sure you have breakfast 2–3 hours before start and tested during training.
Drinking too little. In the days before → loss of performance before the race starts. Dehydration causes a higher heart rate, less efficient sweating and early decay. Hydrate consistently from 48 hours before the race.
Use new supplements or gels. Increased risk of intestinal complaints. Your stomach reacts poorly to unfamiliar products under the stress of a competition. Only use what you tested in tempo or long workouts.
Take gels without water. Stomach problems because the osmolarity becomes too high. A gel needs moisture to be properly absorbed. Without water it remains too concentrated, causing your stomach to protest.
By avoiding these pitfalls, you start lighter, calmer and with a body that knows exactly what to do.
