A registered dietitian drank beetroot juice for a week before running a half marathon to gauge how the nutrient-rich fuel would affect her.
One of the most commonly quoted reasons to run: “I can eat whatever I want!” But should you? To calculate how much caloric damage running really does, we’ve equated the energy burn* from common race distances with the food you’d need to eat to level off your tank. Not that we recommend popping 793 grapes after a marathon—even though it sounds kind of fun to try!
*Calories based on an average 145-pound woman running at a 10-minute per mile pace with relative comfort.
