Hyrox Race Week Nutrition Plan: Exactly What to Eat in the Final 7 Days
Use this Hyrox-specific 7-day nutrition plan to top up glycogen, sharpen hydration, and avoid last-minute mistakes that cost speed and strength.
Quick Answer
For Hyrox race week, keep normal training nutrition early in the week, increase carbs over the final 36-48 hours, maintain sodium and fluid consistency, and execute a tested pre-race meal 3-4 hours before start.
Quick Answer
The best Hyrox race week strategy is simple: do not slash carbs, do not experiment with new products, and do not overhydrate with plain water. Build toward race day with consistent meals, electrolytes, and a rehearsed race-morning routine.
| Feature | Timeline | Primary Goal | Practical Target |
|---|---|---|---|
| Days -7 to -4 | Maintain training support | Normal balanced intake + hydration consistency | |
| Days -3 to -2 | Top up glycogen | Increase carb share while reducing fiber overload | |
| Day -1 | Digestive calm + readiness | Frequent familiar carb-forward meals | |
| Race morning | Stable energy and gut comfort | Pre-race meal 3-4 hours before + small top-up |
Hyrox-Specific Fueling Targets
- Carbs: prioritize availability for repeated high-output efforts across runs and stations.
- Fluids: roughly 400-700 ml/hour around race timeline, adjusted for indoor heat and sweat rate.
- Sodium: typically 400-900 mg/hour equivalent for heavy sweaters in warm venues.
- Caffeine: optional 30-90 minutes pre-race if tested in training and tolerated well.
Common Race Week Errors
- Undereating carbs because you are tapering training volume.
- Drinking large volumes of plain water without sodium support.
- Trying a new gel, pre-workout, or high-fiber meal in final 24 hours.
- Skipping breakfast due to nerves and starting under-fueled.
Race Morning Template
| Feature | When | Action | Example |
|---|---|---|---|
| -4 to -3 hours | Main meal | Low-fiber carb-focused meal + moderate protein | |
| -90 to -60 min | Hydration check | Small fluid + sodium top-up | |
| -30 to -15 min | Optional carb top-up | Small gel or drink carbs if rehearsed |

Should I carb load for Hyrox like a marathon?
You should increase carbohydrate availability, but Hyrox usually needs a shorter, practical 36-48 hour emphasis rather than extreme marathon-style loading.
How much should I drink before a Hyrox race?
Use your sweat-rate trends, but most athletes benefit from steady hydration with sodium instead of large pre-race water boluses.
Do I need fuel during Hyrox?
Some athletes perform better with a small carb top-up depending on event duration and intensity. Test this in simulation sessions first.
