OK, I am usually a roadie, but I'm doing a charity ride for Alzhiemers Association.
I was told that the whole path was mostly flat.
I currently have a hardtail Mountain bike (Jamis Cross County 1.0) which I plan to put less knobby tires in hopes that I roll faster (26 X 1.75). But I am also contemplating a Hybrid (Giant Cypress or Trek 7000?). I was wondering if this can help with comfort and speed. I was told that 700c tires may make a difference in such a distance. Any info/tips will be helpful. My choices are to use my current Mt. Bike or trade it for a hybrid.
I've been to sites about the C&O canal that were somewhat helpful (a yahoo group and bikewashington.org) but there was no real opinion or anything resembling an answer to my question.
I'd like to add that I've gone on a trial run on part of the path and could barely go 12MPH - Most discussions I see mention averaging 13-14mph.
Not sure if my computer is just off. I guess this is the reason I am contemplating 700cc tires. I cycle quite often (obviously Road bikes are faster) and average around 15-17mph on my rides(usually around 20 -30 miles). And that's with some hills.
