Hyrox is 60–100 minutes at a hard, steady effort in an
air-conditioned hall you probably travelled to. Here's what to eat
in race week, the night before, race morning, mid-race and after —
and how to stop a cramp when it starts.
By Dina — HYROX Certified Coach, podium athlete, Jakarta personal
trainer.
Dina's food rules, written for athletes who train hard and eat
normally. Not medical advice — if you're pregnant, diabetic or have a
medical condition, run it past your doctor first.
Part 01
Race week
Nothing new. The week before a race is for eating what your body
already knows, slightly more of it, and salting it. Training volume
drops, so the carbohydrate you eat actually gets stored.
Carbohydrate up, not calories up. From three days
out, make rice, noodles, potatoes, oats or bread the biggest thing
on the plate at each meal. Ease back on fried food and heavy fat —
they slow digestion and you'll feel it at 6 a.m. Sunday.
Salt your food. Living in Jakarta you already
sweat a lot; race week is when you want your body topped up, not
catching up. Extra salt on meals and an electrolyte drink with one
training session a day.
Fibre down from two days out. Swap big salads and
raw vegetables for cooked vegetables and white rice. Less gut
volume, less risk on race morning.
Alcohol off. Even one drink the night before
costs you sleep quality and hydration you can't get back.
Dina's cue
"Boring food, big sleep." If race week is exciting on the plate,
you've got it the wrong way round.
Part 02
The night before
Eat early — 6 to 7 p.m. — and eat normal. A plate of rice or pasta
with a palm-sized portion of chicken or fish and a little cooked
vegetable is perfect. The famous "carb load" pasta mountain the
night before mostly loads your stomach; the storing happened in the
three days before.
6–7 p.m.Dinner: carb-based, low fat, familiar
500 mlElectrolyte drink through the evening
Small snackBanana or toast if you're up late
Lay your race kit and your race food out on the table before bed —
gel, salt, pickle juice, bottle — so morning is autopilot.
Photo slot — swap for a race-morning or kit shot.
Part 03
Race morning
Work backwards from your start time. Everything here has been
practised on a hard training morning at least twice — you're not
trying anything for the first time when it counts.
−3 hMain meal: 80–120 g carbohydrate, little
fat/fibre. Rice or oats with honey, white toast and jam, a bagel
with banana. Coffee if you always have coffee.
−2 h to −1 hSip 500 ml electrolyte drink. Stop
drinking big volumes an hour out.
−40 minTop-up: banana, rice cake with honey, or
half a sports drink. 20–30 g carbohydrate.
−15 minSmall sip of water; optional caffeine gel
or shot if you've trained with it.
If you're an early heat (7–8 a.m.), the −3 h meal becomes a 4 a.m.
alarm. Eat it, go back to bed for 90 minutes. It matters more than
the sleep you lose.
Dina's cue
"Race-morning stomach is a real thing." Liquid carbs — sports drink,
diluted juice — count when solids won't go down.
Part 04
During the race
You don't need to eat much, if anything — but the halls are cold,
dry and you're sweating buckets, so drink you do need.
Under ~75 minutes: a proper breakfast is enough.
Water or electrolyte sips at the row and after the farmers carry.
80 minutes and beyond: one gel or 20–30 g of fast
carbohydrate around halfway — after the burpee broad jumps or in
the Roxzone before the row is the easiest place to get it down. A
second one at the farmers carry if you're heading past 100
minutes.
Doubles: you rest while your partner works — take
your sips then, not while you're running.
Pin it, don't hold it. Gels in a race belt or the
waistband, never in your hand — you'll need both for the sled
rope.
Part 05
Cramps
Hyrox cramps hit in the lunges, the wall balls and run seven, and
they're mostly fatigue plus sweat loss rather than "low potassium".
Prevention is race-week salt and a proper electrolyte drink in the
two hours before. The fix when one starts:
Pickle juice or a mustard sachet. A 30–50 ml
shot. It's not the salt — the sharp taste fires a nerve reflex
that switches the cramping muscle off within about a minute. Dina
carries a small bottle in her race belt; a lot of experienced
racers do.
Change the pattern, don't stop. Shorten the lunge
step, shallow the wall-ball squat for five reps, walk ten steps of
the run. Standing still and stretching makes the next minute
worse.
Then a mouthful of electrolyte. Not a whole
bottle — you'll hear it on the next run.
Dina's cue
"If you cramp in every race, it's your training, not your bananas."
More volume at race intensity is what makes the muscle stop
panicking.
Part 06
Afterwards
Within an hour: 500 ml of something with salt and carbohydrate, then
a real meal with 30–40 g protein and plenty of carbohydrate. Rice,
eggs and sambal is a perfectly good recovery meal. The photo, the
medal and the coffee can all wait twenty minutes.
If you're racing doubles or relay the next day, this hour is the
whole difference between a good second race and a slow one.
Part 07
Racing abroad
Many Jakarta athletes race Bangkok, Singapore, Kuala Lumpur or Hong
Kong. Two nutrition rules for travel races:
Bring your breakfast. Oats, honey, a banana, rice
cakes and your electrolyte powder fit in a hand-luggage bag. The
hotel breakfast doesn't open at 4 a.m. and the convenience store
might not have what you tested.
Eat the local food after, not before. Street food
the night before a race is the most common travel-race mistake
there is. Saturday night is for the pasta you know; the night
market is your reward on Sunday.
Fuel FAQ
What should I eat the night before Hyrox?
A normal-sized carb-based dinner you've eaten many times, early in
the evening. Store carbohydrate in the three days before, not in one
giant plate.
Do I need a gel during Hyrox?
Under about 75 minutes with a good breakfast — usually not. 80
minutes and over, one gel around halfway, practised in training
first.
How do I stop cramping in Hyrox?
Salt your food in race week, electrolytes before the start, and
carry pickle juice or a mustard sachet — the strong taste eases a
cramp within about a minute. Shorten your movement and keep going.
How long before the race should I eat?
Main meal 3 hours before, a small carb top-up 30–45 minutes before.
Nothing new, nothing heavy.
