On the ride- I take along my Cliff bar- cherry crabapple, one bottle of water, and for really tough rides- I fill another bottle with Cytomax.
What I like for recovery when I get home, either Endurox, if wiped out or a sandwich with a light coating of peanut butter, a sliced banana and a slight coating of honey. That gets me jezzed instead of asleep on the floor..
Oh, yes. If like climbing a real mountain- I am a big believer in energy gels. I think it gets me to the top..
