I don't have a road bike, I have a hybrid -- specifically, a Trek 7.3. So far, my longest ride is 28 miles, and I averaged about 13 mph.

Do you think it is possible to train for a century on this kind of bike? Would I be so slow that it's a crazy goal? I've done a sprint triathlon on it as well and on the tri boards they always say "don't worry about the bike, work on your engine" but I know at some point the bike does make a bit of a difference. Just wondering if I am crazy to even consider it.
