GU Energy Gel
If you're out for a few hours and want to perform, go no further. GU Energy gels were made for you. The Energy Gels help by providing you three key nutrients: carbohydrates, electrolytes and BCAA's. The carbohydrates cover your energy losses, the electrolytes keep you well hydrated and the Branched Chain Amino Acids are known to decrease muscle and mental fatigue during your mission.
If you're a person who'd prefer to actually eat something out on the trail consider GU Chews or GU stroopwafels. If you're needing rocket fuel, consider getting some GU Roctane.
Get into it, or as they say... GU for it! (We have no clue about this whole marketing thing, it seems cheesy to us)
P.S. These are gluten free, kosher and made with no animal products
