Yes, eating before your run can enhance energy, especially if you are running longer or more vigorous runs. As for whether you should eat before a run, it depends on your run duration, goals, and run intensity. For quick, relaxed workouts that last about a half-hour, the majority of runners find they can do them pretty comfortably without snacking just before, as long as they’ve eaten normally. It’s usually advantageous to eat before a 60-minute (or longer) run because it can help resupply some muscle glycogen and aid performance. If you’re running first thing in the morning, you do not need a big meal: a banana, a slice of toast, or a few dates should be fine if it is a light session.
