Going for a 5-day commute week, something I don't do very often. Usually bad weather or work commitments force me to drive at least one day each week. This morning it was very foggy and I briefly considered driving, but I rode because it was otherwise very nice -- warm temperatures, no rain, not too windy. What is ironic is that my legs have been toast all week due to a tough group ride on Sunday and some fit issues with a new bike. So, I'm getting lots of miles but my pace is off.
