I wasn't going to put a computer on my road bike for this reason! I didn't want to feel bad if I wasn't as fast as I thought I should be! I did get a computer, but I don't look at my average speed at all while I ride. I found myself doing so the first few times, and then I wound up pushing myself harder than I wanted to, just to bring up my average. I didn't like it. So now, I just leave it set to show the clock and my current speed, I ride the speed I think I should ride when I think I should ride it, and check the rest of the info post-ride. I just want to enjoy.

"I rejoice every time I see a woman ride by on a bike. It gives her a feeling of self-reliance and independence the moment she takes her seat; and away she goes, the picture of untrammelled womanhood."
Susan B. Anthony, 1896
