Sunday, 4-8 am, 16 miles, temps were 35-36F, windchill was 24-25F. I was a little nervous setting out, but I had my back-up Sockwas with me, and within less than a mile my feets had become comfortably numb. That is, they had cooled down but then stabilized at a very slight, easy numbness. After that, the only real probably was my legs. I took lots of walking breaks, as per Dama's MO, since the goal wasn't really running performance, but rather to see how far I could go at sub-zero temps (OK, really sub-zero windchill, since the air temp was above freezing), and to have a little adventure. It was interesting seeing a good chunk of Minneapolis in the dark cold, and then experiencing the sunrise and the warming rays of the sun for the last hour of the run/walk. My calluses still aren't fully reformed, but they seemed to hold up pretty well. Supposed to get up to 60F today. Yippee!
