The Ultimate Diet for HYROX Training

HYROX is an intense and versatile sports competition that combines running with functional fitness exercises like sled pushes, wall balls, rowing, and lunges. This sport requires not only strength and endurance, but also a diet that supports this physical demand. In this article, we'll delve into the best diet to follow during HYROX training, focusing on the role of macronutrients, meal timing, hydration, and supplementation.

The Importance of Nutrition for HYROX

Food is the fuel your body runs on. During HYROX, you use different energy systems: the aerobic system for endurance efforts (like an 8 km run) and the anaerobic system for short, explosive efforts (like sled pushes and burpee broad jumps). Your diet should therefore be varied, focusing on carbohydrates, proteins, and fats.

Step 1 - The Basics

Every Hyrox athlete, from beginner to advanced, should start by building a strong foundation. This means improving your aerobic capacity (fitness) and building your functional strength. In the first 6 to 8 weeks of your training, the focus is on:

  • Long, easy endurance runs (30-60 minutes)
  • Full-body strength training with an emphasis on compound exercises (squats, deadlifts, lunges, presses)
  • Technique training for movements such as sled pushes, wall balls and the rower
  • Mobility work to prevent injuries

 

Endurance training builds your stamina, while strength training provides the physical capacity needed to push sleds or do lunges with a sandbag. In this phase, train 4 to 5 times a week, alternating between heavy and easy sessions.

Carbohydrates

Carbohydrates are essential for HYROX athletes. They are stored in the muscles and liver as glycogen, which is broken down into glucose during exercise for energy. Without sufficient glycogen, performance will rapidly decline.

For a HYROX training regimen It's important to consume sufficient carbohydrates daily. Depending on training intensity, your daily carbohydrate intake ranges from 5 to 7 grams per kilogram of body weight. During an intensive training day or a competition, this can increase to 8-10 grams per kilogram.

Sources of complex carbohydrates like oatmeal, sweet potato, whole-wheat pasta, quinoa, and brown rice provide long-lasting energy. Simple carbohydrates like fruit or sports drinks are especially helpful around training or during competitions here all information about carbohydrates.

Proteins for muscle recovery

Proteins are the building blocks of muscle. HYROX combines strength and endurance training, meaning both muscle recovery and muscle growth must take place. A protein deficiency can lead to reduced muscle mass and slower recovery.

The recommended intake is between 1.6 and 2.2 grams per kilogram of body weight per day. This amount supports muscle recovery, prevents muscle breakdown, and helps with adaptation to training stimuli.

Good sources of protein include chicken breast, eggs, low-fat cottage cheese, tofu, lentils, fish, and plant-based protein powders like pea or rice protein. Distributing your protein intake throughout the day is crucial: each meal should contain about 20-40 grams of protein, depending on your weight our nutritional schedules for inspiration or as an example of how best to organize this, check our blogs for more information about proteins.

Fats

Although fats Often seen as negative, they are essential for hormonal balance and long-term energy supply. They also play a role in the absorption of fat-soluble vitamins (A, D, E, K) and in anti-inflammatory processes.

Unsaturated fats from sources like avocado, olive oil, nuts, seeds, and oily fish (such as salmon) are particularly valuable. Avoid trans fats and limit saturated fats. Fat intake should be around 25-30% of your total daily calorie intake.

Timing and quantity

What you eat is important, but when What you eat is just as important. The timing of your meals can significantly impact your performance and recovery. 

  • Pre-workoutEat a meal rich in carbohydrates and moderate in protein 1.5 to 3 hours before training. For example: whole-wheat pasta with chicken and vegetables. Avoid high-fat or high-fiber meals, which can slow your digestion.
  • During training: For training sessions longer than 90 minutes it may be useful to supplement with carbohydrates (30-60 grams per hour), for example via a sports drink/electrolytes or banana.
  • Post-workout: Within 30-60 minutes after training, consume a combination of carbohydrates and proteins for optimal recovery. Think of a smoothie with banana, protein powder and oats.

supplements/products

Supplements are not a substitute for food, but can complement certain aspects of your diet.

  • Whey or vegetable protein powder: Useful for recovery, especially if you have difficulty getting enough protein through diet.
  • Creatine monohydrateSupports strength production and recovery. 3-5 grams per day is effective.
  • Beta-alanine: Can help with acidification during intensive intervals.
  • CaffeineIncreases alertness and performance, especially in a competitive setting. Dosage: 3-6 mg per kg body weight, 30-60 minutes before the start.

Note: Don't use supplements without first having your basic nutrition in order. Test them during training, not during a competition.

Hydration

Adequate hydration is crucial for thermoregulation, muscle function, and preventing cramps. During HYROX, you lose a significant amount of fluid through sweating. A fluid deficit of just 2% of your body weight can impact your performance.

Drink water throughout the day and replenish during training. Weigh yourself before and after your workout to see how much fluid you're losing, and try to replace it with 1.5 times the amount of fluid you lost. Electrolytes such as sodium, potassium and magnesium are important to supplement during prolonged exertion.

Tailoring to your training

During the build-up to a HYROX competition, your training goals will change, and so will your nutritional needs.

  • Basic phaseFocus on general fitness and muscle building. Slightly higher protein intake, moderate carbohydrates.
  • Intensification phase: More explosive workouts. Increase carbohydrates for energy.
  • Match preparation: optimize glycogen stores, increase carbohydrate intake in the last days before the competition.
  • Recovery phase: reduce carbohydrates, maintain protein intake, increase fats slightly for hormonal balance.

Conclusion

The best diet for HYROX training is one that balances macronutrients, aligns with training times, and provides sufficient variety and micronutrients. By consciously choosing what, when, and how much you eat, you can maximize your performance, recover faster, and confidently approach your next HYROX.

Nutrition isn't an afterthought: it's an integral part of your training. Taking your diet seriously will help you gain ground on the floor. Good luck!
