I'm a newbie, so I guess in part I'm wanting to be sure I have handy stuff to keep me from bonking -- and the food they provide may well be sufficient, I just haven't done the long cycling the ride will require before so I'm thinking ahead...too much?!!

I believe they do provide fruit and stuff at the rest stops, and I know their sport/energy bar of choice is Clif so that's why I was thinking I might experiment with other options while training so I can have some of my own stuff along just in case. Am I over doing it?

Thanks for the clarification on the bloks...by the way!
