The 100 calories of complex carbohydrates found in all 24 pouches of the Energy Gel 24 Pack are only part of the reason why Gu is such a ubiquitous sight in the peloton and on recreational rides. Gu's Energy Gel also packs amino acids, antioxidants, and muscle buffers to help begin the recovery process even while you're refueling mid-event. A splash of caffeine helps kick your engine into fat-burning mode, and the packets are easy to tear and eat -- no chewing, no two-handed fumbling, and no risk of choking on solid food during hard efforts at an unrelenting pace.
