I switched library branches in March, in part for a longer commute. Through the winter I'd only ride directly to and from work at 1.7 miles, and it wasn't enough to stay anything remotely resembling in-shape. A longer commute fixes that.

The new commute is 4.65 miles one-way (between 15 and 20 minutes depending on direction, winds, traffic, etc.) by the most direct and safe route. So far, I've developed several variations out to 16.5 miles. But my favorites are the flat 4.65, a hilly 10.3 and the flat 16.5. This past week, the average of all trips was 11.25.
