I'm 55 and just started biking in late July. I did ride my Schwinn Airdyne daily for 25 years though. I bought myself a new bike, Trek 7100 the day before my birthday Sept.27 and love it. My old bike is an '80's Schwinn Sidewinder mountain bike which I think is going to be my winter bike. Anyway I've already ridden 1300+ miles on my Trek and about 900 on my old bike, so about 2200 since late July. I ride at least 20 miles a day after work and anywhere from 30 to 50 on the weekend days and normally skip Friday. I ride the country rodes of SE Michigan and look forward to riding every day. Cycling just makes me feel good, body and mind.
