Finally hit the teens here in PA (Fahrenheit). I rode on Tuesday and it was in the low 20s (approx -6 Celsius). I forgot my Endura wind pants. Big mistake. I did about 30 miles the last ten in heavy wind and when I got home my legs were as red as lobsters. Went out of Wednesday and it was in the teens. Took the pants, layered up, was pretty warm. I noticed a few ice patches, so yesterday I put my Nokian snow tires on. They're noisy, heavy, and slow, but they really do grip the road. I think it's OK to reduce mileage, maybe even time on these rides. Riding in the cold weather is a lot of work, and if you add the Nokians, it's even more effort. Comments appreciated. 16 degrees today (-8 Celsius).
