Another perfect pre-run snack: a piece of fruit, such as a banana. “For pre-run, you’re topping off energy stores for the workout ahead and keeping blood sugar levels stable beforehand,” says Hadfield.
Bananas are high in fiber, so they’ll keep you feeling less hungry during a distance run. They’re also rich in potassium, which can help keep blood pressure in check, protect your muscle and digestive systems and potentially help ward off muscle cramps.
Add some peanut butter to your banana and you’ll also be getting a healthy dose of niacin, which helps your body harvest energy from carbohydrates, and is good for your digestive system, cholesterol level and heart health to boot. Just make sure you practice portion control. Nut butters sure are scrumptious, but high in calories, so limit your serving to 1 or 2 tablespoons.
