Today was real cold. Below freezing. I wore almost everything I had. Arms, Legs, 2 base layer + jacket, Skull cap, face mask, booties, long finger gloves. All in all, I think my legs were the coldest, then my face. I was well protected, so I never had that feeling of frost-bite or hypothermia. The wind was from the north, so the only time I felt the cold at its worse was on the way back, on the descents. My knee feels stable, a bit sore off the bike still. Concentration was right on, in the zone for the most part. Balance was good. Ailments were next to none. Gear is working well, no complaints there. Other notes, I stopped by Roger's Torah Center on the way back down OTR. I think it added a mile or two to my ride.
