My gym is starting up a 2 hour endurance spin class, oriented towards triatheletes and marathoners. I got invited because they know my penchant for long epic mtb rides..

anyway here's the question: the class is going to be mondays 4:30 -6:30. This is the WORST time of day for me in terms of energy level. I've never done any "training" like this before, (other than just riding)and I am wondering what the best way to fuel myself for best function might be... any and all ideas appreciated. I've always been a "nuts and PBJ sandwiches" in the pack kind of gal, and that's probably what I'd do without any other input... I"m all ears

thanks gals
