HYROX NUTRITION – FUEL YOUR RACE WITH HAMMER NUTRITION UK

Hyrox demands sustained power across 8 km of running and 8 functional workout stations — a unique hybrid challenge that sits between endurance sport and strength training. Get your nutrition wrong and you'll hit the wall mid-race. Get it right and you'll finish strong. Hammer's 40-year endurance nutrition framework maps directly onto what Hyrox athletes need: steady energy, no GI distress, sharp electrolyte balance and fast recovery.

Why Hyrox Nutrition Is Different

A typical Hyrox finish time ranges from 60 minutes (elite) to 90–120 minutes (recreational). That window puts it squarely in the zone where carbohydrate depletion, electrolyte loss and mental fatigue all become performance limiters — but where heavy fuelling causes GI problems. The solution is the same one endurance athletes have used for decades: low-sugar, complex-carb fuel taken in small, frequent doses, paired with consistent electrolyte intake.

Hyrox Fuelling by Race Phase

3 hrs before	Normal balanced meal — carbs, moderate protein, low fat. Avoid anything new or heavy. Hydrate well with water + Endurolytes.
30–60 min before	1 serving Hammer Gel or HEED. Top up electrolytes. Keep it light — no big carb load.
During race (<75 min)	1 Hammer Gel at the start + 1 mid-race. 1–2 Endurolytes Extreme caps every 30 min. Sip water at stations.
During race (75–120 min)	2–3 Hammer Gels spaced evenly. Add Anti-Fatigue Caps from 60 min to maintain mental sharpness. Electrolytes every 30 min.
Within 30 min post-race	Recoverite® — 3:1 carb-to-protein ratio + 3,000 mg L-glutamine. Replenishes glycogen and begins muscle repair in the critical recovery window.

Training Nutrition for Hyrox

Hyrox training combines running intervals, strength circuits and hybrid sessions. Fuel training sessions the same way you'll fuel race day — your gut needs to be trained too. For sessions under 60 minutes, water and electrolytes are sufficient. For longer sessions or double-days, treat it like a race: gel + electrolytes during, Recoverite® immediately after.

Daily protein intake matters more in Hyrox training than in pure endurance sport. The functional strength component creates significant muscle damage. Aim for 1.4–1.7 g protein per kg of body weight on heavy training days. Hammer's protein range — whey, plant and soy — covers every dietary preference.

Key Products for Hyrox Athletes

Hammer Gel	Complex maltodextrin carbs, no simple sugars. Steady energy without the spike-and-crash. Easy to carry, easy to take at workout stations.
Endurolytes Extreme	High-sodium electrolyte capsules. Critical for maintaining muscle function and preventing cramping across the 8 workout stations.
Anti-Fatigue Caps	Branched-chain amino acids + other key nutrients to reduce mental and physical fatigue in the back half of the race.
Recoverite®	Post-race recovery drink. 3:1 carb-to-protein + L-glutamine. Consume within 30 minutes of finishing for maximum effect.
Protein Powders	Whey, plant and soy options. Essential for supporting the strength-training demands of Hyrox alongside endurance recovery.

Hammer's 4 Rules for Hyrox Race Day

• Nothing new on race day. Train your gut with the same products you'll use in competition.
• 120–180 cal/hr maximum. More causes GI distress. Less leaves you under-fuelled in the final stations.
• Electrolytes every 30 minutes. Cramping in the sled push or wall balls is a nutrition failure, not a fitness failure.
• Recover within 30 minutes. The post-race window is when Recoverite® does its best work.
