Hydration on Fight Day: Drinking, Refeed, Timing
From the weigh-in to the first bell: what to drink and eat when, so you step into the ring or onto the mat at full strength.

Fight day doesn't start with the fight, it starts with the weigh-in. What happens in between helps decide whether you go into the first round fresh or flat. The good news: it isn't complicated. The bad news: fight day is the wrong moment to try anything new.
Ground rule: nothing new
Everything you eat and drink on fight day you have tested in training before. No new bar, no drink from the sponsor, no restaurant a friend recommends.
After the weigh-in: water first
Even if you barely dropped water, you drank less than usual up to the weigh-in. So:
- Right after the weigh-in: Half a litre of water or an electrolyte drink in small sips. Not in one go – your stomach won't thank you.
- Then keep going regularly: A few sips every 20–30 minutes until your urine is light again. That's the simplest indicator you have.
- Salt is part of it. Water alone doesn't refill you if you've sweated or reduced salt. A pinch of salt in the drink, salty food or an electrolyte product.
Refeed: easy to digest, carb-rich
After the weigh-in you need above all carbohydrates and fluid, but little fat and little fibre – both slow digestion.
- Good: White rice, pasta, white bread with honey or jam, bananas, rice cakes, sports drinks, diluted fruit juice.
- Less good: Whole grains, big salads, fatty sauces, beans, anything fried.
- Portions: Several small meals instead of one big one. The last proper bite is three hours before the fight.
The last two hours
- Two hours out: a small, familiar portion of carbohydrates (banana, rice cakes, white bread).
- One hour out: sips only. If you drink half a litre before the fight you'll feel it during the warm-up.
- Caffeine, if you're used to it, 45–60 minutes before the fight. If you're not, don't start now.
After the fight
Drink, eat what you like – and get back into the rhythm over the following days. If making weight is a battle every time, it's worth looking at the weight-cut basics before the next fight – or having an honest conversation about the weight class.
