Competition day nutrition is the final piece of an athlete's preparation puzzle. Everything you've built through months of training can be enhanced or undermined by poor nutritional choices in the days and hours before competition. The goal is to arrive fully fuelled, properly hydrated, and without any gastrointestinal discomfort.
The 2-3 days before competition (carbohydrate loading): for events lasting more than 90 minutes, systematically increasing carbohydrate intake (7-10g per kilogram of body weight daily) in the 2-3 days before competition maximises muscle glycogen storage. This "supercompensation" can store 20-30% more glycogen than usual, extending the time before glycogen depletion during competition. For shorter events (under 90 minutes), carbohydrate loading provides minimal benefit.
The competition day: eat a familiar, proven pre-competition meal 2-3 hours before the event. Never try new foods on competition day. Avoid high-fat, high-fibre foods that slow digestion. Stick to carbohydrate-dominated meals you've practised in training: oats with banana, rice with chicken, or toast with eggs. Continue sipping water throughout the pre-competition period (aim to arrive well-hydrated). 30-60 minutes before competition: a small carbohydrate snack (banana, rice cakes with honey) and ensure you've consumed enough fluid. During competition: follow your established strategy - don't experiment. Post-competition nutrition is also important: prioritise rehydration and carbohydrate restoration to facilitate recovery for subsequent competition or training.
