We've all been there: halfway through the second WOD, legs giving out, stomach turning. More often than not, the problem isn't a lack of training. It's what was on the plate the night before. Whether it's a cross training competition, a Hyrox race, or a CrossFit®-affiliated event, nutrition is just as important as the workouts leading up to it.
The night before: fuel up without overdoing it
The goal the evening before is straightforward: top off glycogen stores without weighing down your digestion.
- Focus on complex carbs: rice, pasta, sweet potatoes, quinoa
- Lean proteins: chicken, turkey, white fish
- Limit excess fiber: raw vegetables, legumes, cruciferous veggies — they slow digestion and cause bloating
- Skip heavy fats: fried foods, rich cheeses, heavy sauces
Dinner should be familiar. The night before a competition is not the time to try a new restaurant or an exotic dish. Stick with what you know, in normal portions.
Golden rule: nothing new on competition day. Everything you eat should have been tested during training.
Competition morning: the most important meal
Breakfast should be eaten 2 to 3 hours before the first WOD. This allows for full digestion without any heaviness.
The winning combo
- Medium glycemic index carbs: oatmeal, whole grain bread, banana
- Light protein: eggs, Greek yogurt, whey
- A touch of healthy fat: peanut butter, a handful of almonds
What to avoid
- Coffee on an empty stomach (acidity + stress = bad combo)
- Pastries and pure fast sugars (insulin spike followed by an energy crash)
- Too much volume: aim for 400-600 kcal, not a full brunch
If the competition starts very early and you can't eat 3 hours ahead, a light snack 60-90 minutes before works well: a banana with some peanut butter, or an energy bar you've already tested.
Between WODs: strategic refueling
This is often where it makes or breaks. Between events, the body needs to quickly replenish its stores without overloading the stomach.
- Within 15-20 minutes after each WOD: a carb drink or a few sips of diluted fruit juice
- 30-45 minutes after: a light solid snack — banana, granola bar, rice pudding
- Continuous hydration: small regular sips, not a whole bottle at once
Quantity guidelines
| Time between WODs | Strategy | |---|---| | Under 30 min | Liquids only (sports drink, gel) | | 30 min to 1h | Quick snack (banana, applesauce, bar) | | Over 1h | Light mini-meal (rice + cold chicken, sandwich) |
Electrolytes matter too. When sweating for several hours, water alone isn't enough. A pinch of salt in your bottle or a sports drink helps prevent cramps and early fatigue.
Common mistakes to avoid
A few traps come up at every competition:
- Testing a new gel or supplement on race day — stomach issues guaranteed
- Skipping breakfast due to nerves — your body needs fuel
- Stuffing yourself between WODs — frequent small bites beat one big meal
- Forgetting to drink — dehydration tanks performance long before you feel thirsty
- Relying on caffeine to fix everything — one morning coffee, yes. Three espressos at noon, no
Build your nutrition routine
The best approach is to test your nutrition during intense training sessions. Long WOD days or mock competitions are the perfect opportunity to validate your fueling plan.
Write down what works, what doesn't sit well, and adjust. On competition day, all you have to do is follow a proven plan.
