Eat a normal carb-rich dinner. Keep it familiar. Do not test a new gel, drink, or tablet.
Race-Day
Fuel
HYROX is too short for marathon fueling and too long to wing it on a pre-workout. The right plan is small, calm, and rehearsed: carbs when they help, electrolytes matched to sweat, and no panic drinking.
01 - The 60-110 minute problem
This is not a four-hour fuel story.
A typical HYROX race sits somewhere between a hard threshold run and a strength-endurance test. The runs keep pulling on aerobic energy; the sled, lunges, burpees, and wall balls add hard spikes. That means you need enough carbohydrate to stay sharp, but not so much that your stomach becomes the ninth station.
HYROX fuel is a top-up plan. Eat enough before the start, carry a small amount during the race, and protect hydration from becoming a guessing game.
02 - Build the plan
Your race-day fuel planner
Use your real target finish time. Treat the plan as a starting point, then test it during hard sessions before Delhi or Mumbai.
Carry salt with your fluid. Do not use plain water alone. Drink to stay steady, not to force the bottle down.
Eat 120-160 g carbs from foods you know sit well.
If you do not know your sweat rate, use a normal electrolyte drink. Check your sweat rate after your next hard session.
Take a small carb top-up only if you have used it in training. Use caffeine only if it is already normal for you.
Aim for about 45 g carbs per hour. Use about 2 gels. Pack 3 if gels are your only carb source. Carry 500-750 ml with electrolytes.
Weigh in before and after a hard session. Use that to set your refill number.

Nothing new on race day. Do not drink just to match sweat loss. Too much water can be dangerous. These are estimates for healthy adults. If you have a medical condition or a past heat issue, work with a sports doctor or dietitian.
03 - Before the gun
Most fuel happens before you enter the tunnel.
For most athletes, the useful pre-race meal is about 1.5-2 g carbohydrate per kilogram of bodyweight, eaten early enough that it is not sitting heavily in the stomach. For an 80 kg athlete, that is roughly 120-160 g carbohydrate: familiar breakfast foods, low drama, no new fibre bomb.
The night before should look boring in the best way: enough carbs, normal salt, normal protein, and a meal you already know. Race week is not the moment to discover whether a new gel, magnesium tablet, or pre-workout agrees with you.
04 - During the race
Use carbs when the clock justifies them.
| Finish time | Carb target | Practical read |
|---|---|---|
| Under 60 min | 0 g/hr | Start fed; do not force mid-race fuel. |
| 60-90 min | About 30 g/hr | One gel or a small bottle strategy can be enough. |
| 90-110 min | About 45 g/hr | Usually two gels in practice; pack a third if needed. |
| 110+ min | About 60 g/hr | Practice timing and make sure your stomach agrees. |

05 - Fluids and sodium
Replace enough. Not everything.
Delhi in July and Mumbai in September are indoor events, but warm-up areas, humidity, nerves, and repeated high-output stations still produce real sweat loss. The useful target is not "drink as much as you sweat." It is to avoid a large gap while staying inside gut comfort and keeping sodium in the plan.

06 - The ORS label trap
ORS is not automatically a sports drink.
WHO-formula ORS is built for clinical rehydration, especially fluid loss from illness. That does not make it the best during-exercise fuel for HYROX. It can be sodium-heavy, light on race carbs, and easy to confuse with ready-to-drink products that borrow the ORS language without matching the formula.

The form matters more than the claim.
Cramps in HYROX are usually a fatigue, pacing, heat, and sodium problem first. Magnesium is not a magic brake for wall balls. If you use it, the label still matters: glycinate, bisglycinate, and citrate are more defensible than oxide when absorption is the point.
The current Fast&Up pick here is Magnimax, which uses more defensible magnesium forms than basic oxide. Still, treat magnesium as support, not a cramp cure.

08 - The simple race-week rule
Rehearse the boring plan.
The final plan should fit on one note: familiar carb meal, rehearsed gel timing, electrolyte bottle, no new products, and a post-race refill with sodium and normal food. If your sweat rate is still a guess, start with the sweat-rate calculator, then come back to the fuel planner.
