Hyrox Race Nutrition Guide

Introduction

Nutrition plays a key role in achieving your best performance in Hyrox on race day. This article will break down how you can fuel your body effectively in the runup to, on the morning of, and throughout race day.

Week of Race Nutrition Prep

The week leading up to your race is very important. Two things you want to avoid are last-minute changes and chasing your nutrition right before the event. This can lead to unexpected nutrition stress and impact your performance. To address this follow these tips:

Stick to familiar foods

Experimenting with newer foods and supplements right before your event may lead to digestive issues. Always try to stick to meals you’ve already tried and tested. The importance of replication cannot be stressed enough. Practice your snacks, breakfast, meals and nutrition products you plan to use in and around race day.

Carbohydrates

Ensure that your diet is aligned with the right carb-loading strategies, which we will go over shortly.

Meal Prep

Plan your meals out beforehand, ensuring that your portions and ingredients are consistent. This should help you have more control over what you consume.

Plan Race Day Meals

Once you know around the time that your race will start, plan out your race day meals. The best strategy here is to work back from your start time as this allows you the best chance feeling fuelled.

Travel Considerations

Take into consideration travel; if your event requires travel, either bring your own meals or research food options on location before you go. 

Tapering

As you get closer to your race, start to taper down your training intensity and volume to allow your body to recover properly and begin to store energy. This is essential regardless of your level of fitness.

Carb Loading 

Whilst carb loading for Hyrox may not be as essential as when doing longer events such as a Marathon or Iron Man, you still want to prevent glycogen depletion on race day. Glycogen (the stored form of carbohydrates) are a key determinant of your exercise performance with HYROX being a form of exercise that will deplete glycogen relatively quickly.

To avoid reduced power output and fatigue, make a form of carb loading something to consider.

How to Carb Load for Hyrox

Don’t overload on carbohydrates all week. A gradual increase from 48 hours before the event would be sufficient to keep topping up your glycogen stores without making you feel bloated.

Instead of taking a 1 or 2 big pre race meal, aim for regular, consistent and smaller intakes to add to your glycogen stores whilst reducing the risk of gastric discomfort. The idea of consuming as much pasta as you can on the night before is not advised.

Think about adding extra snacks, larger servings of carbs at main meals or drinking liquid carbs between meals. Small changes rather than sweeping changes to your current diet.

Event Day Nutrition for Hyrox

For Hyrox race day, your priorities are maximisation of energy, minimisation of fatigue, and maintaining your mental clarity. Here are some of our main tips to help you perform.

  1. Try to stick to your normal routine. For example, whatever you usually have for breakfast before you train is probably best for before competition. Avoid new foods; race day is not the time to experiment and try new things. Just stick to what your body already knows.
  2. Hydrate yourself early and consistently. Aim to start hydrating way before your race to avoid even slight dehydration, which can limit your performance. Be sure to check out our electrolyte sachets whilst you’re here. 
  3. Try to mix solid and liquid carbs. By combining solid foods with liquid carbs, you can maintain more steady energy levels by minimising digestive strain. 

Hyrox Race Day Carbohydrate Guide

2-3 Hours Pre Race

Consume 1g of carbohydrate per kg of body weight, focusing on low protein, fat and fibre foods. 

30 Minutes Pre Race

Consume 20-40g of liquid carbohydrates to deliver quick energy without digestive stress. You can use gels or the MARCHON Workout Fuel (you can use the caffeine free version if your start time is in the evening)

During the Hyrox Race

It’s unlikely you will need anything during a Hyrox race, but if you do, take a gel at station 4 or 5 to get the most benefit.

Incorporating Caffeine on Race Day

Caffeine is proven to have benefits on physical performance, including:

  • Increasing muscular endurance, especially for events lasting 20-250 minutes, improving stamina and power. 
  • Improving power based movements with short bursts of sprinting or jumps.
  • Caffeine can help improve your concentration and also reduce your perceived effort, making more work potentially feel easier. 
  • Caffeine can also reduce actual fatigue. 

Timing of Caffeine

Take caffeine around 30 minutes before your race to allow time for absorption.

Dosage of Caffeine

Aim for around 2.5-3mg of caffeine per kilogram of body weight, adjusting it based on your personal tolerance. 

Sources of Caffeine

Any source of caffeine works, whether it is coffee, preworkout like workout fuel or just a caffeine supplement will work fine.

A Supplement Guide for Hyrox Athletes

Supplements can help you fill nutritional gaps, but they are most effective when combined with a balanced diet. Here’s a quick guide to our supplements for Hyrox.

Workout Fuel

Energy Gels

Post Race Recovery

As natural as it is to want to go straight back into training after a hyrox race, it is essential that you follow a recovery protocol to help maintain your long-term health and performance. Intense exercise can weaken your immune system temporarily, which can leave you vulnerable to illness. 

4 Key Nutrients for Recovery

Omega 3

Omega 3 will help your cellular regeneration, muscle recovery and immune function.

Vitamin C

Vitamin C will aid collagen production and tissue repair, which is essential for faster recovery.

Antioxidants

Load up on colourful fruits and vegetables like berries spinach and kale to combat oxidative stress and inflammation. 

Pre/Probiotics

These are needed for optimising gut health, which plays a role in immunity. Fermented foods, yoghurts and kefir can help promote a healthy gut.
