HYROX Race Week Nutrition

This page plans the seven days before a HYROX event, including travel and heat time. The pre-race meal itself and in-race carbohydrate have their own pages.

How should I eat during HYROX race week? Keep race week familiar. Eat roughly as you have been, keep carbohydrate adequate as training drops, test your race-morning meal before the taper begins, and plan travel food and heat-time meals in advance. Whether a formal carbohydrate load makes sense depends on how long you expect to race.

Why race week needs a plan, not just restraint

HYROX publishes one fixed format: eight 1 km runs alternating with eight workout stations, so every athlete covers 8 km of running plus 8 stations. Because the format is fixed and published in the official rulebook, the hard simulations and the race-morning meal test can be finished before the taper. Race week then becomes logistics: travel, where you will sleep, what you can reheat, and when your heat starts.

Taper often lowers training volume faster than appetite falls. Some athletes cut food sharply; others treat the week as a free-for-all. Common practice in sports nutrition is to keep foods familiar, because unfamiliar food or supplements add a variable you have not tested. How much risk that carries is individual.

• Do the race-morning meal test before the taper, not during it
• Lower training volume, similar appetite: expect the mismatch
• Travel shrinks food options, especially gluten-free ones
• Heat time decides how many meals you need on race day

What the evidence says

The 2016 joint position statement on nutrition and athletic performance describes carbohydrate loading in the 36–48 hours before sustained or intermittent events longer than about 90 minutes, and everyday carbohydrate intake that scales with training. It recommends individualised plans. It is general sports guidance, not a HYROX study.

The 2026 consensus discussion keeps adequate carbohydrate availability as the mainstream approach. The contemporary review stresses scaling to the event's duration and intensity. Protein is a daily habit: the ISSN position stand describes about 1.4–2.0 g/kg/day as sufficient for most exercising people.

How strong is this evidence? We are not aware of a study testing race-week protocols in HYROX athletes. The guidance here is general sports nutrition applied to a published format. Whether a formal load fits you depends on your expected finishing time and is best decided with a sports dietitian.

A practical framework

Days 7–4 out

• Eat as you have been through training; protein at each meal
• Race-morning meal test should already be done; if not, do it at an easy session
• Confirm your heat time and the venue's food and storage rules

Days 3–2 out

• Keep carbohydrate adequate as training drops
• If your expected race time is long enough that you are considering a load, use a plan you have tried before
• If you are prone to gut trouble, keep fibre at levels you know you tolerate
• Order or pack travel food now

Day before

• Familiar meals, normal portions
• Fluids spread across the day
• Lay out race-morning food, with a backup option

Travel and packing checklist

• Cooler and ice packs for chilled meals; keep chilled food cold until you reheat it
• Check that your accommodation has a fridge and microwave before you leave
• Follow the storage and reheating instructions on each meal label
• Pack race-morning food plus one spare in case the heat is delayed
• Coeliac or gluten-free athletes: bring safe food rather than relying on unfamiliar restaurants

Early heat vs late heat

• Early heat: the main meal may be breakfast only; set alarms to keep your tested gap
• Late heat: plan a normal breakfast plus a later main meal at your tested gap, rather than stretching one breakfast
• Delayed heat: have the spare snack you tested; avoid a large unplanned meal close to the start

An example race week with travel (not a prescription)

Sunday (day 6) — before the taper

• Last hard simulation; race-morning meal test done

Mon–Wed (days 5–3)

• Normal meals; order or prep travel food

Thursday (day 2) — travel

• Cooler packed; check fridge and microwave on arrival

Friday — day before

• Familiar meals; race-morning food and a spare laid out

Saturday — late heat

• Normal breakfast; tested main meal at your usual gap before the heat

One example shape. Your week depends on heat time, travel distance and what your gut tolerates.

Where gluten-free actually fits

Our kitchen is 100% dedicated gluten-free because some people need it to be — coeliac disease, diagnosed gluten sensitivity, or a household that simply eats gluten-free. Removing gluten is not a performance strategy in itself, and there is no good evidence it improves output, recovery or inflammation in athletes without a medical reason. Race week is where planned gluten-free food matters most for coeliac athletes: travel and unfamiliar restaurants raise the chance of accidental exposure.

Frequently asked questions

Should I cut weight in HYROX race week?

We do not give cutting plans. Sharp last-week restriction lowers carbohydrate availability in the week you least want that. Body-composition goals belong to the training block, ideally with a registered dietitian.

Should I carb-load for HYROX?

General guidance links formal loading to sustained or intermittent events longer than about 90 minutes. Many HYROX athletes finish in less time, and many take longer. Base the decision on your own expected time, and only use a loading plan you have tried.

Is it too late to try a new supplement?

Race week is a poor time for anything untested, including supplements and energy products. If something is new, save it for the next training block.

What if I am travelling and cannot eat my usual food?

Use the travel checklist above: a cooler, confirmed fridge and microwave, reheating to label instructions, and a spare race-morning item.

My heat is late in the afternoon. What changes?

Usually one more meal. Eat a normal breakfast, then your tested main meal at your usual gap before the heat. Keep a tested snack in case the schedule slips.
