Before

Before a long run, eat a snack to recharge your batteries. Ideally, reach for something that’s mainly carbohydrates with modest amounts of fiber, fat, and protein. If you’re going for a jog or running for less than an hour, drink plenty of water.

During

During intense runs lasting more than 1 hour, performance foods like gels and chews provide quick carbohydrates (fast fuel) to working muscles, helping to prevent the dreaded “bonk.”

Stay hydrated with 4–6 ounces of fluid every 15–20 minutes. Reach for water or try sports drinks to help replace sodium lost in sweat.

Timing

30-60g of Carbohydrates / Hour

After

After a long run, drink plenty of water and focus on foods and drinks with carbohydrates and complete protein (like meat, dairy, and soy). Carbohydrates help restore muscle-energy stores (glycogen), while protein encourages muscle repair.
