I rode my longest ride so far since getting my bike last week. Don't know the exact mileage (don't have a cyclometer yet) but I rode for an hour and fifteen minutes. (I must admit it was mostly on very flat terrain, with the exception of the stretch going back home which is almost entirely uphill on a slight grade.) So maybe it was somewhere between 12-15 miles?

Baby steps...

BTW it got up to 92 degrees here today. Niiice!
