24F in Madison, too
"Coldest ride of the season for me. When I left the house it was 24F but the sun was out and not much wind so it wasn't all that bad. Rest of the week should be a bit warmer than today. The chill seemed to keep my speed down a bit. I usually average around 15.8 - 16.0 but today was only at a 15.4. Didn't see any other riders and only saw a handful of joggers this morning. People at the office thought I was nuts. Whatever!! "
I'm 100 miles west of you and had my coldest morning yet, too. It seemed as if the cold kept the lubricating fluids in my aging knees and ankles from flowing properly for quite some time. :-) Worst part was coming home in the dark and cold, unable to see the road surface clearly. I stuck to larger roads, which then put me in the path of careless neighbors in their cars. I hope to ride at least until Xmas.
