Race week is not the time to test anything new — not shoes, not gels, and definitely not your diet. The week before a half marathon is about giving your body what it already knows how to use: steady carbohydrates, enough fluid, and just enough restraint to avoid a stomach full of regret at mile 6. Here’s how to eat your way to the start line feeling ready instead of wrecked.
For the first few days of race week, keep your meals close to your normal routine. This isn’t the window for carb-loading — that comes later. Focus on whole foods, lean protein, and vegetables, and keep hydrating consistently. If you’ve been fueling well all training cycle, this part should feel boring. Boring is good.
Rule of thumb: if a food hasn’t shown up on a long run before, it doesn’t get to show up on race week either.
This is when you gradually shift your plate toward more carbohydrates and slightly less fiber and fat, which can slow digestion and sit heavy before a run. Good options include rice, pasta, and potatoes; oatmeal and low-fiber cereals; bananas, bagels, and toast; and lean proteins like chicken, eggs, or tofu in moderate portions. You don’t need to double your portions — think “more rice, less broccoli” rather than an all-you-can-eat pasta bar. Overdoing it just adds bloat, not glycogen.
The day before the race, keep meals simple and low in fiber and fat. A classic move is a carb-forward dinner — pasta with a light sauce, rice with grilled chicken, or a baked potato with some protein on the side. Skip the celebratory buffet, the new sushi spot, and anything spicy or unusually rich. Hydrate steadily throughout the day rather than chugging water all at once in the evening.
Eat a light, familiar breakfast 2–3 hours before the gun goes off — think toast with peanut butter and banana, oatmeal, or a bagel with a bit of jam. Stick to what you’ve used before long training runs. Sip water or a sports drink in the final hour, and if you use gels or chews mid-race, make sure they’re the same ones you’ve already tested.
Race week nutrition isn’t about doing something special — it’s about not messing up what’s already working. Keep it familiar, lean slightly more into carbs as the race approaches, stay hydrated, and save the celebratory meal for after you cross the finish line.
