Pre-Ride Meal Calculator — What to Eat Before Cycling

Ideally 2-4 hours before for a full meal, allowing digestion. A lighter snack can be eaten 1-2 hours before. Within 30 minutes of riding, stick to simple sugars only (gel, sports drink).

Focus on carbohydrates (60-70% of the meal), moderate protein, and low fat. Easy-to-digest foods are best: porridge, toast, rice, bananas. Avoid high-fibre, spicy or fatty foods.

Yes. For a race, eat a larger carb-focused meal 3-4 hours before, then a small snack 1 hour before. Stick to familiar foods — never try anything new on race day.

Fasted rides (easy intensity, under 90 minutes) can help fat adaptation. However, for hard or long rides, eating beforehand improves performance significantly.

Per the ACSM, drink about 5-7 ml/kg of body weight at least 4 hours before riding — roughly 375-525 ml for a 75 kg rider. If your urine is still dark (or you have not produced any) closer to the start, add a further 3-5 ml/kg in the final 2 hours. Urine should be pale yellow before you set off.
