I'm 72 and try to ride every day when the Chicago weather warms up to 60 or so. We have a paved loop trail nearby that is 13 miles long and it makes a nice hour ride. In Florida in January we ride every day from 25 to 30 miles per outing; usually to a restaurant halfway than back.
BTW we ride Schwinn World GSE electric bikes and pedal all the time.
