your plan sounds good. maybe too much eat and not enough drink. then again you can get calories from HEED?

i love Hammer. for me on a hard 3 or 4 hour ride i would go with two bottles of HEED and two of water. a Cliff Bar mid ride and some gel at the end if needed. post ride consist of Recoverite and some PB&J samiches. works for me, may not for you.

good luck with the ride. later.
