100 ft/mile is often considered pretty hilly. That would certainly slow you down, especially if you are heavy (I don't remember if you said and I don't care to go back and look through all the posts). It also would make the extra weight of the mountain bike have more affect, and the suspension
Stupid but honest question - he's doing loops and ending at the same elevation that he started out at... shouldn't he be making up a little time on the down side, anyway?
