I think of a hill as anything that noticeably goes up. Something you might have to shift down for or work hard to get up. It doesn't matter how long it is, a couple hundred yards or a couple miles, it's still a hill.

I can't say that I go uphill any faster than you do, Lynne. I am working hard to develop the mental attitude that hills are my friend though. You can't really ride around here without hitting some hills so I figure I'll enjoy the rides better if I think 'woohoo, another hill I can challenge myself with' rather than 'oh darn, not another hill already'.
