What to Eat Before HYROX: The 24-Hour Race Day Nutrition Plan
You have done the running.
You have pushed the sled.
You have discovered exactly how unpleasant 100 wall balls can become when your legs have already completed 8km of running.
Now race day is approaching.
One of the biggest mistakes you can make at this point is completely changing the way you eat.
HYROX combines eight 1km runs with eight functional workout stations creating a demanding mixture of endurance and repeated high-intensity muscular work. HYROX itself suggests that the average competitor may be working for around 90 minutes.
That means nutrition matters.
But race-day nutrition does not need to be complicated.
The aim of the final 24 hours is simple:
Top up your energy stores, arrive well hydrated, keep your stomach comfortable and give your body fuel it already knows how to use.
This is not the time to discover a new superfood, consume six scoops of pre-workout or eat a family-sized bowl of pasta because somebody on TikTok said "carb loading".
Here is how we would approach it.

# The Golden Rule: Never Experiment on HYROX Race Day
Before discussing carbohydrates, electrolytes or caffeine, remember this:
Nothing new on race day.
Your pre-race breakfast should have been tested during training.
Your electrolyte drink should have been tested during training.
If you use caffeine, test it during training.
If you use a gel, test it during training.
Sports nutrition guidance consistently recommends practising competition nutrition beforehand because unfamiliar foods, large meals and new products can cause gastrointestinal discomfort at precisely the moment you don't need it.
Think of your harder HYROX simulation sessions as nutritional dress rehearsals.
Don't just test whether your legs can handle sled pushes followed by running.
Test whether your stomach can handle your planned breakfast too.

24 Hours Before HYROX: Start Filling the Tank
Your nutritional preparation begins the day before the event rather than at breakfast on race morning.
Carbohydrate is particularly important because hard exercise relies heavily on carbohydrate stored within the muscles and liver as glycogen.
Research and sports nutrition guidance supports increasing carbohydrate availability before competition and intense training. Pre-event recommendations commonly suggest carbohydrate intake in the hours before exercise to help maximise available fuel.
That doesn't mean you need an extreme traditional marathon-style carbohydrate load.
Instead, make carbohydrate a larger and deliberate part of your meals during the day before HYROX.
Good options include:
* Rice
* Pasta
* Potatoes
* Sweet potatoes
* Bread
* Bagels
* Oats
* Cereal
* Fruit
* Bananas
* Rice cakes
* Crumpets
Protein should still be included, but the day before your race isn't the time to build every meal around enormous portions of steak.
Think:
**Carbohydrate + moderate protein + relatively simple foods.**
---
Example Breakfast: 24 Hours Before
A simple breakfast could be:
Porridge with banana and honey
plus
Greek yoghurt
or
Eggs and toast
with fruit on the side.
You could also use TBJP Performance Protein mixed into porridge or as a shake if that is already part of your normal diet.
Protein contributes to the growth and maintenance of muscle mass, but remember that the main nutritional priority immediately before a HYROX race shifts towards ensuring carbohydrate availability and good hydration.
The protein powder isn't going to drag the sled for you.
Sadly.
---
Lunch the Day Before
Keep lunch familiar and carbohydrate-based.
For example:
Option 1
Chicken
White rice
Small portion of vegetables
Option 2
Pasta
Lean chicken or turkey
Tomato-based sauce
Option 3
Jacket potato
Tuna
Small amount of salad
Vegetarian option
Rice or pasta
Tofu or another familiar protein source
Cooked vegetables
Don't suddenly turn lunch into an enormous cheat meal because you're "carb loading".
A massive burger, chips, onion rings and cheesecake contains carbohydrate, certainly.
Unfortunately it also contains enough fat to keep your digestive system occupied with administrative paperwork for several hours.
---
What About Fibre?
Normally we actively encourage people to eat plenty of vegetables, whole grains, pulses and other fibre-rich foods.
The day before an endurance event can be slightly different, particularly if you are prone to digestive problems.
Athletes who experience gastrointestinal issues may benefit from temporarily reducing very high-fibre foods during the final 12-24 hours before racing. Sports nutrition guidance also recommends keeping the pre-event meal relatively low in fibre and avoiding excessive fat because these can contribute to stomach discomfort in susceptible athletes.
That can mean choosing:
* White rice instead of brown rice
* White pasta instead of wholegrain pasta
* White bread or bagels
* Cooked vegetables rather than huge raw salads
* Bananas rather than enormous bowls of high-fibre fruit
This isn't advice to eat like this every day.
It's simply about making digestion easier before competition.
---
Hydration Starts the Day Before Too
You cannot properly hydrate yourself by drinking two litres of water ten minutes before entering the start tunnel.
All you will accomplish is visiting the toilet repeatedly.
Start paying attention to hydration during the entire day before your race.
Drink regularly rather than forcing enormous amounts at once.
A simple indicator is urine colour.
You're generally looking for pale yellow, rather than completely clear all day or dark yellow.
And remember that hydration isn't simply about water.
Sweating also results in electrolyte losses.
These include sodium, alongside minerals such as potassium, magnesium and calcium.
LSC DRIP Hydration Formula
This is where our LSC DRIP Electrolyte Formula can fit naturally into a HYROX nutrition plan.
Each serving provides approximately:
175mg sodium
420mg potassium
75mg magnesium
75mg calcium
alongside a small amount of carbohydrate.
DRIP can be mixed with 300-500ml water according to the product directions and used before, during or after exercise.
You could use a serving during the afternoon or evening before your race if that is already part of your normal hydration strategy.
However, more electrolytes isn't automatically better.
People vary enormously in how much they sweat and how much sodium they lose.
Heavy sweaters or athletes racing in hot conditions may need an individualised hydration strategy.
---
Your Evening Meal: Keep It Boring
I mean that as a compliment.
The night before HYROX is not MasterChef.
You want something familiar, enjoyable and easy to digest.
A simple meal could look like:
Chicken + Rice
* Grilled chicken
* White rice
* Small amount of cooked vegetables
* Light sauce
Pasta
* White pasta
* Lean beef, chicken or turkey
* Tomato-based sauce
Salmon + Potato
* Salmon
* Potatoes
* Small serving of cooked vegetables
Vegetarian
* Rice
* Tofu
* Lightly cooked vegetables
* Familiar sauce
You don't need to eliminate fat completely.
Just don't make the meal extremely high in fat.
And don't eat until you feel like you're expecting triplets.
The goal is to go to bed comfortably fuelled, not stuffed.
---
Don't Forget Your Normal Supplements
If you normally use supplements such as:
* Creatine
* Multivitamin
* Krill oil
* Magnesium
take them according to your normal routine and product directions.
There is no need to suddenly double doses because HYROX is tomorrow.
Creatine in Particular
If you already take Gym Squad Supps Micronized Creatine Monohydrate, continue taking your normal daily serving.
Creatine is not something you need to suddenly load the evening before HYROX.
Its benefit comes from consistently maintaining muscle creatine stores over time.
Creatine is one of the sports supplements recognised by the Australian Institute of Sport as having strong evidence for use in appropriate sporting situations.
Race week is about continuing your established routine, not inventing a new one.
---
# Get Some Sleep
This is technically a nutrition article, but sleep deserves mentioning.
Finishing your perfect chicken-and-rice meal before staying awake until 1am watching HYROX videos isn't exactly elite preparation.
Aim for a sensible bedtime.
Have your kit prepared.
Know your journey.
Know your start time.
Know what you're eating for breakfast.
Reduce as many race-morning decisions as possible.
And if nerves mean you don't sleep perfectly the night before, don't panic.
One imperfect night's sleep doesn't erase months of training.
---
Race Morning: The Main Pre-HYROX Meal
Now we get to the important bit.
Sports nutrition guidance generally recommends eating the main pre-event meal approximately 2-4 hours before exercise.
For carbohydrate specifically, broader sports nutrition guidelines commonly recommend approximately 1-4g of carbohydrate per kilogram of bodyweight in the 1-4 hours before exercise, with the amount depending on timing, athlete size, event demands and individual tolerance.
That is deliberately a wide range.
You don't need to sit at breakfast with a calculator and laboratory scales.
The closer you are to the race, the smaller and easier to digest the meal generally needs to become.
Your breakfast should ideally be:
Carbohydrate rich
Relatively low in fat
Not excessively high in fibre
Easy to digest
Familiar
Sports Dietitians Australia recommends exactly this sort of approach for pre-exercise meals.
---
Good HYROX Breakfast Options
Option 1: Porridge
Porridge
Banana
Honey
Small amount of yoghurt
This works particularly well if you've used it successfully before training.
---
Option 2: Bagel
Plain bagel
Honey or jam
Banana
Small yoghurt
Simple and relatively easy to digest.
---
Option 3: Toast or Crumpets
2-4 slices of toast or crumpets
Jam or honey
Banana
Add a small amount of protein if desired.
---
Option 4: Cereal
Low-fibre cereal
Milk
Banana
Something as simple as cornflakes can actually make more sense immediately before competition than a heroic bowl containing seventeen ancient grains and half a rainforest of seeds.
Race morning isn't a competition to see who can produce the healthiest-looking Instagram breakfast.
---
Option 5: Cream of Rice
Cream of rice
Banana
Honey
Potentially add a small amount of TBJP Performance Protein if this is something you have already used before training.
---
What If My HYROX Starts in the Afternoon?
HYROX start times vary, so not everyone will be racing first thing in the morning.
If you're racing later in the day, don't make the mistake of eating breakfast at 7am and then hardly eating because you're nervous.
For an afternoon event:
Breakfast
Normal carbohydrate-focused breakfast.
For example:
Porridge + banana + yoghurt.
Lunch
Approximately 3-4 hours before racing:
Rice + chicken
or
Pasta + lean protein
or
Bagel + banana + yoghurt if you prefer something lighter.
Final snack
Approximately 60-90 minutes beforehand if required:
Banana
Rice cakes
Crumpet with honey
Small cereal bar you already tolerate
Sports drink or familiar carbohydrate drink
Sports nutrition guidance supports a normal meal earlier in the day followed by a lighter carbohydrate snack closer to competition for athletes with later start times.
---
Two to Four Hours Before HYROX: Hydration
You want to arrive at the start line hydrated without feeling as though your stomach is an aquarium.
General sports hydration guidance recommends drinking steadily before competition rather than trying to correct dehydration immediately before exercise.
Research-based guidelines have suggested approximately 5-7ml of fluid per kilogram of bodyweight around four hours before exercise, with additional fluid potentially needed if urine remains dark or output is low.
For a 70kg athlete, 5-7ml/kg would represent approximately:
350-490ml
For an 80kg athlete:
400-560ml
For a 90kg athlete:
450-630ml
This isn't a challenge to drink that amount in one enormous gulp.
Sip fluid sensibly.
Your total needs also depend on:
* Body size
* Temperature
* Sweat rate
* What you've already drunk
* How much sodium you lose
* Your individual tolerance
---
Where DRIP Fits on Race Morning
If you've successfully used LSC DRIP during your HYROX training, race morning is an obvious time to incorporate it.
Mix one serving with 300-500ml cold water according to the product directions.
Sip it in the period leading up to your event rather than necking it on the start line like somebody has just shouted last orders.
Remember:
DRIP forms part of your hydration strategy.
It doesn't replace your entire food intake.
And you don't need four servings because four must logically be four times better.
Human physiology remains annoyingly more complicated than that.
---
What About Coffee or Caffeine?
Caffeine is one of the better researched sports-performance ingredients.
Research suggests caffeine can improve several aspects of exercise performance, including aerobic endurance and muscular endurance, although individual responses vary substantially.
Studies frequently use approximately 3-6mg of caffeine per kilogram of bodyweight, commonly around 60 minutes before exercise, although some people may respond to lower amounts and higher doses increase the likelihood of unwanted side effects.
This does not mean everyone should calculate 6mg/kg and swallow it.
If you're normally a one-coffee person, race day isn't the moment to transform into a laboratory experiment.
Too much caffeine can leave you:
* Jittery
* Anxious
* Nauseous
* With an uncomfortably high perception of heart rate
* Desperate for the toilet
If caffeine is part of your strategy, use an amount you have already successfully tested in hard training.
And account for all sources of caffeine.
Coffee + energy drink + pre-workout + caffeinated gel can add up very quickly.
We'll cover caffeine and pre-workouts properly in another article in this HYROX series.
---
60-90 Minutes Before HYROX
At this stage, the heavy lifting nutritionally has already been done.
You don't need another meal.
If you're hungry or want a final carbohydrate top-up, keep it small.
Options include:
* Banana
* Rice cakes
* Crumpet with jam or honey
* Small cereal bar
* Familiar carbohydrate drink
If you're feeling full, don't force food down just because your nutrition plan says you should.
The aim is to arrive at the start:
Fuelled, hydrated and comfortable.
Not waddling.
---
15-30 Minutes Before the Start
This is where people often begin panicking.
They see somebody eating a gel.
Suddenly they want a gel.
Someone drinks a mysterious fluorescent liquid.
Suddenly that looks essential too.
Ignore them.
If you have practised a small carbohydrate intake immediately before racing and know it works for you, stick with your plan.
Otherwise, don't introduce something new.
Have a few small sips of fluid if required.
Warm up.
Get yourself organised.
And remember you have already eaten properly.
---
Should You Eat During HYROX?
This depends partly on your expected race duration and what you have practised.
For prolonged high-intensity exercise extending beyond approximately an hour, sports nutrition research supports carbohydrate intake during exercise, with recommendations often around 30-60g per hour depending on the event and individual.
However, HYROX presents practical challenges.
You're running, pushing, pulling, lunging, rowing and performing burpees.
This isn't a Sunday bike ride where you can casually unwrap a sandwich.
Some competitors may benefit from:
* A carbohydrate gel
* Sports drink
* Easily consumed carbohydrate
particularly if their expected race time is longer.
But you should practise this during HYROX simulations first.
If consuming a gel halfway through training causes your digestive system to launch an official protest, finding that out during competition would be unfortunate.
---
Foods I'd Avoid Before HYROX
In the final few hours before racing, be cautious with:
Huge amounts of fat
Fried food
Very fatty breakfasts
Heavy creamy sauces
Large quantities of cheese
fibre
Huge salads
Bran cereals
Very high-fibre bread
Large servings of beans or lentils if you're sensitive
spicy foods
Your intestine doesn't need additional competition.
alcohol the night before
Hopefully self-explanatory.
portions
More food doesn't necessarily mean more energy available during the race.
you've never tried
Race day should contain as few surprises as possible.
The sled will provide enough of those.
