So what you should eat before, during, and after a run?
Balanced meals for runners should comprise roughly 20% fats, 60% complex carbohydrates and 20% proteins. It real terms imagine a bowl of pasta with a fresh tomato sauce, as many vegetables as you like and a handful of cooked, chopped chicken on top.
Before a run
Try to avoid foods that are high in fibre and fat before your run as they are much harder to digest and could cause problems along the way. Reach for a small, low-fiber, high-carb snack 30-60 minutes before your run. A good pre-run snack would ideally contain around 50g of carbohydrates.
Try: Think two bananas, two slices of bread or toast with some honey or peanut butter. Granola bars are good as long as they don’t contain too much sugar, or a handful of dried, mixed fruit.
