Proper Nutrition for Endurance Sports & Training: Sports Nutrition Tips

Are you a passionate endurance athlete and wondering what the best nutrition is to support your athletic performance? Whether you run, cycle, or swim long distances: your energy level is closely linked to what you eat and drink. In this blog, you'll learn everything about sports and nutrition and get practical tips for every endurance athlete.

Why nutrition is crucial in endurance sports

Good nutrition is the foundation for top performance and strong endurance for athletes. Whether you run, cycle, swim, or regularly do strength training with light weights and many repetitions: your body needs the right nutrients. These collectively ensure that your energy level remains stable and that you recover faster after exertion.

Carbohydrates are the primary fuel for your muscles during exercise. For athletes, this means 5 to 7 grams of carbohydrates per kilogram of body weight daily, increasing to 10 grams on heavy training days. Grains such as wholemeal bread, oatmeal, and brown rice are excellent sources, as are fruits and energy bars. These not only provide carbohydrates but also fiber, vitamins, and minerals. Fiber from whole grains and fruit keeps your digestion balanced and provides sustained energy.

During prolonged exertion, you deplete your glucose stores: glucose is the direct energy source that powers your muscles. It's wise to have a meal with sufficient carbohydrates and fiber 2 to 3 hours before your training. For sessions longer than 60 to 90 minutes, you can replenish energy with, for example, an energy bar or banana, to maintain your performance level.

Minerals also play an important role. Magnesium, found in nuts, seeds, and whole-grain products, supports your muscles and helps prevent muscle cramps. Since you lose minerals through sweating, it's important to replenish them, for example, with magnesium-rich foods like nuts, seeds, and whole-grain products.

After your training, a combination of carbohydrates, proteins, and fats (such as yogurt with fruit or a wholemeal sandwich) helps promote muscle recovery. Don't forget that strength training with small weights and many repetitions also benefits from this nutritional strategy. This way, you keep your muscles strong and stay energetic, no matter which endurance sport you choose.

What is endurance sport?

Endurance sport encompasses all sports where you are active for a long time, at a relatively low to moderate intensity. Think of running, cycling, swimming, rowing, or cross-country skiing. These sports are all about endurance: your body must efficiently deliver energy over a longer period.

At Fitwinkel, we notice that more and more athletes want to improve their performance not only through training but also by seriously addressing their nutrition. With our years of experience in the fitness and sports industry, we know how important it is to align nutrition and training.

The role of carbohydrates during endurance sports

Carbohydrates are the main energy source for endurance athletes. During prolonged exertion, your body primarily uses glycogen, a form of carbohydrate stored in your muscles and liver. When this supply runs out, you feel tired, lose strength, and your performance can quickly decline. Therefore, it is crucial to maintain your carbohydrate reserves before, during, and after your training.

How many carbohydrates do you need?

The exact amount depends on the duration and intensity of your training, but a general guideline for endurance athletes is 5 to 7 grams of carbohydrates per kilogram of body weight per day. On heavy training days or during competitions, this can increase to 10 grams per kilo. This means, for example, that an athlete weighing 70 kilos can use between 350 and 700 grams of carbohydrates per day.

Examples of good carbohydrate sources

• Wholemeal bread and pasta
• Rice and potatoes
• Oatmeal
• Fruit (bananas, apples, raisins)
• Sports drinks or gels for longer exertion

Sports nutrition: what to eat when?

The timing of your nutrition is just as important as its content. Here are a few practical tips:

Before training

Eat a carbohydrate-rich meal 2-3 hours before your training, for example, a plate of pasta with vegetables, a rice salad, or oatmeal with fruit. This ensures that your glycogen stores are well-filled.

During training

For efforts longer than 60-90 minutes, it's wise to take extra carbohydrates along the way. Think of a sports drink, a banana, an energy bar, or sports gel. This helps to keep your energy levels up and prevent 'hitting the wall'.

After training

Afterwards, it's important to replenish your carbohydrate stores, preferably within an hour. Combine carbohydrates with some protein for faster muscle recovery. A bowl of quark with fruit, a sandwich with chicken breast, or a recovery drink are good options.

Hydration: do not underestimate it

In addition to proper nutrition, adequate hydration is essential for endurance athletes. During prolonged exertion, you lose a lot of fluids through sweating. This can negatively affect your performance. Drink enough water or an isotonic sports drink before, during, and after your training, especially in warm weather or during intensive training.

Practical tips for endurance athletes

• Create a nutrition plan tailored to your training schedule
• Always test new foods during a training session, not on race day
• Vary different carbohydrate sources to prevent deficiencies
• Use sports drinks, bars, or gels only as a supplement to your regular diet
• Listen to your body: everyone reacts differently to nutrition during endurance sports
