I am hooking up with a fast group ride that leaves at 5am. I would like to sleep until about 430am, get up, dress and out the door at 4:50am to arrive at meeting place at 5. The ride is fast according to guy who asked me. I'll have 300 on-board calories in my drink (ride lasts 90 minutes). What should I drink or eat before I head out? My normal routine won't cut it. I'm thinking 8 oz. chocolate milk and a banana. thoughts?
