my daily commute to school is a little more than 6mi. I don't have a computer on my bike, (one of the reasons I ride my bike is to escape from technology), but from the map I created on mapmyride.com my RT is 12.78mi.
Maybe once I find a job, my commute will be a little longer.
My ride to the beach is only 15mi. Powder white sand beaches of Pensacola.
