Yeah, after my ride on that bike path, I was like, "Aw man, I bought the wrong kind of bike . . ." So to make myself feel better I started going for some light offroad rides, you know, places where a roadie could never go. That made me happy.
And I also figure that, due to my bike, I'm getting a better workout than I would if I had a light, high-geared, narrow-tired road bike.
But I also thought that those people zipping around didn't really look like they were in especially fantastic shape or anything. I think it was the bike making them go faster, not the rider.
