For racetime fuel my secret was always (and still is) bananas. That is all I would eat all day. Gives you lots of energy, absorbs quick and has enough potasium to prevent cramps or arm-pump. For hydration it was always water or flat 7uP. Everyone is different but this is what worked for me. Real gatorade (the powedered stuff) works quite well too. In my first real trial with it I entered a 100mile Xcountry at the last minute a few years back. No prep and had'nt ridden for 3 months prior. All I had was some gatorade. After I few 60min laps I was beat, so I guzzled a jug of gatorade at each pit stop. The energy boost was dramatic and I felt like superman...but only for 3/4 of a lap until it wore off. Had planned to ride it just for fun but got the holeshot, the old adrenaline came back, and had to go for it! Old guys rule....sometimes. Cam.
