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.

HyroxRace WeekNutrition StrategyPerformance

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.

Most athletes perform best with progressive carbohydrate emphasis in the final 2 days, not an extreme one-night carb binge.
Hydration is a daily process: target pale-yellow urine and include sodium, especially if you are a salty sweater.
Keep food choices familiar to reduce GI risk under high-intensity station transitions.

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.

Frequently Asked Questions (FAQ)

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.
