Though they make sports drinks and accessories, the folks at Gu are most known for their energy gels - those small little packets of viscous fluid that gives you the energy to keep moving. In the gel category, they compete with [Clif Shots], [Carboom], [Power Shots] and a few others.

Gu is primarily a carbohydrate drink that energizes and sustains you during exercise. If you are involved in endurance racing (or any demanding physical activity that lasts more than 2 hours), it's time you started to appreciate the taste of the energy gels, and Gu is as good a place as any to start. Honestly, I think it all comes down to flavors.

The gu flavors include:
* Vanilla Bean
* Espresso Love
* Chocolate
* Tri Berry
* Lemon Sublime
* Strawberry Banana

It seems the most popular flavors are Tri Berry and Espresso Bean (thanks to it's Caffeine kick).
