Eat enough before you run
I know some people who go on a morning run after a quick cup of coffee or a piece of fruit. More power to ya, but my body says “hell no” when I try to do that. I need to eat at least 7-10 grams of protein and complex carbs before a run. Not only that, I need to do this at least an hour before I go in order to feel fueled enough. Coffee may give you a boost, but it can also be dehydrating, so you’re better off sticking with water.
