Ok, I don't like riding in the cold. I don't have enough or the right kind of clothes. It was a balmy 45 degrees today, and windy, but sunny. I set out to do one of my regular routes, but repeat the hill a few times. I got to the top and was still cold. At that point I decided to just finish the route and go home.
Here's a picture of the hill. It's known locally as the Col d'Costco. It's a little over 1/2 mile long and a good 9-10% grade. Today my Garmin showed a 12% peak, but I think that was wrong.
