The night before cycling you should eat a high-carbohydrate meal (65-75% calories from carbs) with some lean proteins and healthy fats. Here are a few ideas:
Pasta topped with salmon and sauteed vegetables
Brown rice bowl with grilled chicken and roasted vegetables
Turkey burger on a bun with a baked potato
Brown rice noodles with stir fried veggies and pan-fried tofu
Eating a high-carbohydrate meal paired with protein and fat the night before cycling will help max out your body’s glucose reserves (i.e. glycogen) while also providing satiety and a source of slow-burning fuel while you sleep.
