I have yet to meet a hill on the road that I can't get up. I've got really small gears though - 24 x 27. The slowest speed I've seen was like 2.5. I don't remember it exactly, but it was on DMD two years ago - Patterson pass into a headwind.

Off road - I walk if needed. Depending on the ride I may turn around and try again or just walk up the hill.
