So this morning I got out and ran my standard 2-mile course — this time in 16 minutes so that's feeling really good. The outside temperature was 37°F and breezy but the most exciting part was that I got to run in flurries. Occasionally one would sting my tongue with its cold pinprick. And yeah, once again, I ran it barefoot. When I got back I checked the temperature of the bottoms of my feet and they were a chilly 58° but pink from adequate blood flow. It didn't feel too much different than when I ran last time in the cold weather, but this time there was some moisture on the ground from the rain last night and that made it draw more heat away. I'll stick with it and see what happens, ever watchful of how my toes are feeling.
