But it looks a bit silly when there are 20 others in class who ride out of the saddle in 'running' position when you keep seated all the time..
At 62 years old, I simply don't care any more how I look to others. I guess this is one of the reaons I enjoy riding solo or just with my wife. I do what I want, when I want, no questions asked. If I want to put on my Levis and ride in an old sweatshirt, I do exactly that. If I want to get all dolled up in in biking paraphernalia, I do that.
I like not caring. It makes life a lot easier.
