jeez.. we should do some sort of forum-wide poll for just height and weight!
cycling is a smaller persons sport and i think most of the ppl who responded to this thread are over 6ft and 200lbs!
i'm not surprised that so many folks here are in their 40s, but i expected.. well.. smaller ppl i guess.
i'm almost 34, very tall and skinny, and slow as poo. i just got a computer when i got my new bike a few months ago and i only seem to avg 15-16mph. i'm thinking (hoping) that might be because so much of the riding i do is on paved bike paths which i believe are just inherently slower than car roads. i live in DC though, so i definitely don't have hills as an excuse.
been off the bike for a few years with overuse injuries (which in case you're curious were pretty much eradicated by going to back to eating meat after years of being vegetarian) so maybe when i have more than a season of riding in my legs the speed and strength will come up on it's own.
