What do you keep in your bottles and bring for a snack on longer rides? I'm a mountain biker and buying a road bike in the coming weeks that I'd like to eventually start racing with. When I go on longer(2-3hrs) rides I generally fill my Camelback with 60oz water and bring a Cliff bar. For road biking I Was thinking of going with 1 water, 1 Gatorade, a cliff bar, and maybe some raisins. I was wondering what everyone else carries and if what I'm planning to bring is sufficient? Are the powder mixes any good? Should I drink one bottle before the other?
