I can't eat much on a long ride, so I go with Gatorade - lemonade flavor is like rocket fuel. (Have you noticed that Gatorade is now "G"? My children at the University of Florida report that thre is a bit of an uproar about the branding change.) I'll eat Snicker marathon energy bars too, and pop a few Advil along the way. I might change to Excedrine with cafeine and see how that goes.
