HYROX Nutrition: How to Plan Your Fuelling

HYROX Nutrition: How to Organise Your Plan

A HYROX nutrition plan should account for your expected exercise duration and tolerance of foods and drinks. Planning begins during training.

What has research examined?

In a study of 11 participants completing a simulated HYROX event, the median completion time was 86.5 minutes. Researchers recorded demanding exercise responses during the combination of running and functional exercises.

The study did not test a nutrition protocol. It therefore does not establish that a particular number of gels or a specific breakfast is ideal for HYROX.

Where do carbohydrates fit?

General sports nutrition research supports adjusting carbohydrate intake to exercise demands. Both preceding meals and fuelling during prolonged exercise matter. Applying these principles to HYROX is a practical adaptation, rather than a specifically validated protocol.

What should you record during preparation?

Keep a brief record of:

The timing and contents of your previous meal.
Training duration.
Products and quantities consumed.
Any difficulty consuming them.
Digestive comfort through to the finish.

Test your planned food and drinks in training before using them in competition.

How do you count gels and drinks together?

Hypothetical label example:

One gel provides 25 g of carbohydrate.
The amount of drink you actually consume provides 20 g.
Total intake: 45 g of carbohydrate.

This is a calculation example, not a recommended dose. If you consume half of that drink amount, the total becomes 35 g.

Frequently asked questions

Does everyone need the same number of gels?
No. The number of packets alone does not tell you how much carbohydrate you consume or whether it fits your plan.

Should I count the entire bottle?
Count the amount you actually consume.

What should I check before the event?
Your start time, available facilities and the specific event’s rules on carrying food or drinks.
