One hour before a long run, what is the best way to fuel my body? —Angie
JB: Carbohydrates! I recommend a small meal that contains approximately 30 grams of carbs for runs lasting longer than an hour. Half a bagel, an English muffin or a small bowl of cereal will fill this requirement. You should look for foods that are low in fiber in order to prevent upsetting your stomach during the run. Pay attention to exactly what you consume and how it makes you feel during your workout. Next time, tweak this if necessary. Finding your perfect pre-run snack may require some trial and error.
