I guess I'm not the only one.
Don't feel bad. I'm in my late 50s, ride for recreation and fitness- and am alone most of the time.
Last year I inquired at a local bike shop about meeting up with the women's group they have-and got the distinct impression that I didn't fit their stereotype.
She emphasized how fast they ride and added that surely I'd rather ride with a group closer to home. (I was only about 10 miles from home-and I do have a way to transport my bike.) Oh well...
