The importance of nutrition for endurance athletes!

Endurance athletes, be they runners, cyclists, swimmers or triathletes, need a specially tailored diet to increase their performance and recover from intensive training sessions. In this comprehensive blog article, we will explain the basics of optimal nutrition for endurance athletes and introduce some Athletic-Supplements products that can help them achieve their athletic goals.

The importance of nutrition for endurance athletes

A well-balanced diet is crucial for endurance athletes as it helps provide energy, increase endurance, speed recovery and prevent injury. Proper nutrition can also help protect the body from muscle loss and overtraining. Here are some important factors endurance athletes should consider in their diet:

1. Carbohydrates as the main source of energy

Carbohydrates are the most important source of energy for endurance athletes. They are stored in the muscles in the form of glycogen and serve as a quick source of energy during exercise. A diet rich in carbohydrates helps replenish glycogen stores and increase endurance.

Product tip: At Athletic-Supplements you will find, among other things, the Isotonic Carbloader , specially developed for the needs of long-term training loads. The special formula of carbohydrates with vitamins and minerals allows you to train longer and harder.

2. Protein for recovery

Protein is crucial for repairing and building muscles. Endurance athletes should ensure they consume enough protein to prevent muscle loss after intense workouts and promote recovery.

During intensive endurance training, muscles are stressed and tiny tears occur in the muscle fibers. Protein is the building block needed to repair this muscle damage and promote muscle regeneration. Protein intake after training helps prevent muscle breakdown and supports the building of new muscle mass.

To recover from endurance training, it is advisable to consume a protein-rich meal or a protein shake. Ideally, this should be done within 30 minutes to two hours after training at the latest. This time window is often referred to as the "anabolic window" because the body is particularly receptive to absorbing nutrients during this time.

Product tip: Athletic-Supplements offers high-quality protein products , including vegan protein, which consists of 3 components. It is ideal for supporting muscle regeneration.

3. Fats for endurance

Fats are an important source of energy for endurance athletes and play a crucial role in increasing endurance. While carbohydrates are the preferred and quickly available energy source for short-term, intensive activities, endurance sports that require longer efforts rely on the body's fat reserves as energy suppliers. Here are some reasons why fats are very important for endurance:

Long-lasting energy:

Unlike carbohydrates, which are consumed quickly, fats provide a long-lasting source of energy. They are stored in the body in the form of fatty tissue and can provide energy over a longer period of time.

Conservation of carbohydrate reserves:

Using fat as fuel during exercise conserves limited glycogen stores in the muscles and liver. This is particularly important for endurance athletes as glycogen is the preferred source of energy during high intensity.

Stabilization of blood sugar levels:

Fats help keep blood sugar levels stable by slowing the absorption of carbohydrates. This can help prevent energy peaks and troughs during long workouts.

Maintaining muscle mass:

Adequate fat intake is important to protect muscle mass. During long, intense workouts, the body may begin to use muscle protein as an energy source. The presence of sufficient fat in the body helps prevent muscle loss.

It's important to note that not all fats are created equal. Healthy, unsaturated fats found in foods like avocados, nuts, seeds, and olive oil are the best options for endurance athletes. In addition to providing energy, these fats also have anti-inflammatory properties and support overall health.

However, athletes should limit saturated fats and trans fats, which are found in fried foods and processed snacks, as they can increase the risk of inflammation and cardiovascular disease.

4. Hydration and electrolytes

Endurance athletes not only lose water when they sweat, but also vital electrolytes such as sodium and potassium.

Adequate hydration is crucial to prevent dehydration during training or competition. Dehydration can lead to rapid exhaustion, muscle cramps, an increase in heart rate, and a drop in body temperature. It is important to note that thirst often only occurs when the body is already dehydrated. Therefore, athletes should drink water regularly, even if they don't feel thirsty.

Recommended fluid intake may vary depending on individual factors such as intensity of exercise, ambient temperature and sweat loss. As a rule of thumb, endurance athletes should aim to consume around 500ml of fluid per hour of moderate activity and increase this amount during more intense workouts.

5. Antioxidants and vitamins

Endurance sports can lead to increased oxidative stress. Antioxidants like vitamins C and E can help minimize cell damage and support immune function.

6. Timing and meal planning

Proper meal planning and meal timing are critical to providing energy for training and promoting recovery. Athletes should eat appropriately before, during and after training.

A typical nutrition plan for endurance athletes

To put the above principles into practice, here is an example of a typical nutrition plan for an endurance athlete:

Breakfast (2-3 hours before training):

Snack (30-60 minutes before training):

  • An energy gel or a banana

During training (if necessary):

  • Water or an electrolyte drink (Isotonic from Athletic Supplements)
  • Energy gels or sports drinks

After training (within 30 minutes):

  • A protein shake or EAAs from Athletic Supplements
  • A serving of rice or whole-grain pasta with vegetables and lean protein (chicken, tofu, fish)


  • Grilled salmon with quinoa and steamed vegetables
  • A large green salad with olive oil and balsamic dressing

    The evening meal should consist of a balanced combination of protein, complex carbohydrates and healthy fats. Grilled salmon with quinoa and steamed vegetables is an excellent option. This meal promotes nighttime recovery and ensures that the body is supplied with important nutrients.

Snack (before bed):

  • A light snack before bed can help support muscle recovery during sleep. A glass of low-fat milk or a casein protein shake is recommended, as casein is slowly digested and supplies the body with amino acids overnight.

Planning meals around training and considering proper nutrient distribution are critical to maximizing athletic performance and speeding recovery. It is advisable to adapt meals individually to your own training times and needs.

    We at Athletic Supplements provide you with our products to achieve your goals in the best possible way. Be active and be an athlete.
