Caffeine

Make a Starbucks run! Caffeine aids sports performance for many people. Endurance activities are most affected by java-jolted sports nutrition, with runners being able to go longer without tiring, but some studies have indicated shorter duration activities may also benefit. However, large doses of caffeine in a sports nutrition diet may be harmful. Some people do not benefit, and may suffer nervousness or have trouble staying hydrated. But if you’re used to it, a cup or two of coffee before your run or ride may feel helpful to you. Don’t take any more than that, and try it in practice before using it in a race.
