Athletes consume energy bars for a variety of reasons, including fuel during a workout or race; using a bar as a meal replacement; and noshing on a bar as a snack. Endurance workout and race durations can vary wildly from around 20 minutes to 17 hours or more. Generally, it's not necessary to consume an energy bar for a workout or race that is shorter than 90 minutes.
Which energy bar you choose for any situation depends on your current daily diet composition, food preferences, food allergies and dietary goals. Below, you will find a comparison of various energy-bar-type foods that endurance athletes are known to consume. This chart is sorted by the total number of carbohydrates contained in the bar, beginning with the lowest and ending with the highest.
