There’s a reason why bananas are a frequent sight at running events. They are an excellent source of potassium, a mineral that your muscles need to contract properly. Insufficient potassium can lead to muscle cramps. Have a banana 30 minutes before a run, during a run or immediately after. Besides eating it plain, you can slice and add it to cereal or blend into a smoothie.
