Hammer Gel +...
Hammer is my fuel of choice but I can't stomach countless gels over the course of long hours. My endurance fuel of choice is to mix a thick cake-battery paste of Hammer Perpetuem with Hammer Gel and a little water. I go for plain or vanilla on the gel because I can't handle too-sweet flavors on long, long days. (If you do go for the mix option, try using a food processor to get a nice smooth consistency.) Now Backcountry needs to start selling Perpetuem.
