I did 10 miles today since we're to have Arctic air moving in that will bring our daytime high temps down to single digits and drop us sub-zero at night. It was cold enough today--low 20s. I hadn't ridden since a bout of flu. I almost didn't go for the ride, but couldn't stand the thought that I may not be able to get on the bike most of next week. (I'm not going to try to ride when our highs are 5 or 8F and we've got steady winds of 8 MPH with gusts of 15 MPH. I don't have a death wish.)
