3.3 miles each way. But, I do errands & such, so I average 14 miles a day.
My recreational riding per week doubles the number of miles I ride (~100 miles/week total). But that tends to be longer rides, less often. 100 miles/week is a lot and I am getting a lot of flack for it both at home and at work, so I suspect & hope that number will drop with the temperature.
