Deal with getting no less than 100 energy of a carb-rich meals like a banana, a handful of pretzels or entire grain cereal, or a slice of toast. (After your run, you may eat the remainder of your breakfast and get within the protein, fruits, and veggies you skipped earlier, she says.) An vitality gel pack with round 100 energy is one other good possibility.
