To ride in a few charity events each summer/fall season, (and most importantly stay in skiing shape) I ride my touring bike 3-days a week for 12-16 miles per and 25-40 miles one morning every other weekend. For fun, we break it up with some trail riding on our property or find a small group trial rides in Southern NH.
We spent two days riding the carriage roads in Acadia National Park this past Memorial Day weekend as well as hiking up Cadillac Mountain.
To be honest, riding bicycyles makes feel 30-years younger.
