Hyrox is one of the fastest-growing fitness races in the world. The format is standardized globally: athletes run 8 x 1km intervals, with a functional fitness station after each run. The eight stations are always in the same order — SkiErg (1km), sled push (50m), sled pull (50m), burpee broad jumps (80m), rowing (1km), farmer's carry (200m), sandbag lunges (100m), and wall balls (100 reps). Total course distance is roughly 8km of running plus all eight functional stations.
Finishing times range from around 55 minutes for elite athletes to over 2 hours for recreational participants. The mixed demand of aerobic running and muscular endurance makes Hyrox uniquely challenging from a nutrition standpoint — it is neither a pure running race nor a pure strength event.
Pure endurance athletes can rely on high-carb, low-protein approaches. Pure strength athletes prioritize protein and lower carbs. Hyrox athletes need both simultaneously.
Fuel the aerobic running legs and glycolytic demand of the functional stations. Higher on training days, moderate on rest days.
Support muscle repair from sled pushes, sandbag lunges, and wall balls. Target 1.8-2.2g per kg of body weight daily.
Provide sustained energy and support hormonal health. Keep fat intake moderate and adjust it alongside carbs between training and rest days.
Carb periodization is the practice of matching carbohydrate intake to training demands. It is one of the most powerful tools in a hybrid athlete's nutrition toolkit.
On days with long runs, double sessions, or Hyrox-specific interval work, carb intake should be elevated (4-6g per kg body weight). This ensures full glycogen stores going into the session and rapid replenishment afterward. You will perform better, recover faster, and adapt more effectively.
On strength-focused training days with sled work, farmer's carries, or lifting, carbs can be moderate (3-4g per kg). Protein should be kept high to support muscle protein synthesis.
On full rest or active recovery days, reduce carbohydrates to 2-3g per kg while maintaining protein intake. This creates a modest caloric deficit on rest days, which can improve body composition over time without compromising training performance.
The week before a Hyrox race requires a deliberate taper in training volume alongside strategic nutrition adjustments to arrive at the start line fully fueled and feeling sharp.
As training volume tapers, increase carb intake to 6-8g per kg body weight. Focus on rice, pasta, oats, potatoes, and fruit. Reduce fat and fiber to avoid GI discomfort during the race.
Eat 2-3 hours before the race: 1-3g carbs per kg body weight from familiar foods like oatmeal, toast with honey, or a banana. Avoid high fiber, fat, and new foods. Have a small caffeine source if it is part of your training routine.
For races under 75 minutes, a single gel or energy chew around the midpoint plus water is usually sufficient. For 90+ minute efforts, aim for 30-45g carbs per hour via gels, chews, or sports drink.
Within 30-45 minutes of finishing, consume 30-40g of protein and 60-80g of carbohydrates to maximize glycogen replenishment and muscle repair. A protein shake with a banana or a chicken and rice meal work well.
Several supplements have strong scientific support for the demands of hybrid endurance-strength events like Hyrox.
Increases phosphocreatine stores, directly benefiting the explosive strength demands of sled pushes, wall balls, and sandbag lunges. 3-5g daily is sufficient; no loading phase required.
Buffers lactic acid buildup during high-intensity functional stations, reducing the burn in legs and arms during sled pulls and burpee broad jumps. 3.2-6.4g per day; tingling (paresthesia) is normal and harmless.
Improves both endurance performance and power output. 3-6mg per kg body weight taken 45-60 minutes before a race or training session. Habitual users should consider a 5-7 day caffeine taper before race day to restore sensitivity.
Hyrox is a global fitness race combining 8km of running with 8 functional fitness stations. Because it blends aerobic endurance with strength and power, standard marathon or powerlifting nutrition plans fall short. Hyrox athletes need periodized nutrition that fuels both energy systems with higher carbs on hard training days and adequate protein throughout for muscle recovery.
A Hyrox race typically burns 600-1,200 calories depending on weight, fitness level, and finishing time. Elite athletes finishing in under 60 minutes burn 600-800 calories, while recreational athletes finishing in 90+ minutes may burn 900-1,200. The mixed aerobic-strength demand makes caloric expenditure higher per minute than a standard run of the same duration.
The day before a Hyrox race, focus on carb loading with 6-8g of carbohydrates per kilogram of body weight. Good choices include rice, pasta, bread, oats, potatoes, and bananas. Keep fat and fiber intake low to avoid GI distress. Maintain normal protein intake and stay well-hydrated. Avoid alcohol and unfamiliar foods.
For most athletes completing Hyrox in under 90 minutes, minimal in-race fueling is needed. A fast-acting carb source before the race and one energy gel around the halfway point is common practice. Elite athletes finishing in under 60 minutes often rely solely on pre-race nutrition. For 90+ minute efforts, plan for 30-45g of carbohydrates per hour using gels or sports drinks.
Carb periodization means strategically adjusting carbohydrate intake based on training demand. On heavy training days you need more carbs to fuel performance. On rest days, reducing carbs while keeping protein high supports recovery without excess calories. This approach improves body composition, enhances training adaptations, and teaches the body to become more metabolically efficient.
Hyrox athletes should target 1.8-2.2g of protein per kilogram of body weight daily — higher than standard endurance recommendations because of the significant strength demands. For a 75kg athlete, this means 135-165g of protein daily. Spread intake across 4-5 meals, prioritizing 30-40g within 30-60 minutes post-workout.
