I don't know about that. The goal of 20mph pace is kind of an arbitrary figure. I just used it because it was a round number. I'm working within the factors of age, strength and build. I'm not exactly the most aerodynamic person. I tell people I do these things, not because I have an athletic build, rather I do it in spite of it. Too short and too wide to be a good athlete.

I do what I can with my equipment. I know some people hate them but I have clamp on aero bars for my bike, not so much for the aero but to relieve arm fatigue. Still, I'm sure it's not hurting my aero either. Once I finish school, I'm going to look for a decent used tri bike. I have no idea if that would help at all but I'd really like to try one.
