Do mostly solo rides as go out every other day being retired. Trying to do more group rides. One of our local groups does 18 - 21 MPH or faster on Saturdays. We ride together in double file so good chance to talk. Had trouble keeping up especially at corners and stops. Getting stronger and hope to keep up sometime soon. Getting dropped after 15 or 20 miles now.
Advantage of groups is riding 25-30% faster with less effort plus cameraderie.
Riding alone means no one to keep up with or talk to but can ga as fast as like and stop when like. Both have pluses and minuses eh?
