I live in the flat plains and most of my rides average in the 15-17 range- when I'm on my carbon tri bike. When I'm on my steel commuter I average between 11-13. A hill around here is only about a 200 ft elevation change, but there aren't too many. I've been riding about 6 years, have done more centuries than I can count, more triathlons than I can count, one Ironman, and lots of short bike tours.

Funny how different people can be because I couldn't care less how I compare to others. I mostly ride alone because competition turns me into a green demon who is not pleasant to be around. Numbers mess with my head and make me go crazy with negative self-talk (I'm not fast enough, that ride wasn't long enough, I should have a higher avg., etc). I often will take the computer off the bike and just go ride for the sake of riding. There was a year a few years ago when I hated riding and it was because of the numbers (on the computer, the garmin, the HR monitor). I'm good enough and riding makes me happy- that's mostly what I care about. I'm never going to be as fast as some, and I'm probably faster than a few. Like Popeye says: I am what I am!
