day 12

Well, I gave it a go...layered up...and went outside for a run at 6am. It was 27* outside, and I felt pretty good. Towards the end, my lower lip was starting to get numb. Maybe it really was cold. I don't know. I had a hard time keeping my HR in the 140-145 range, so I had to stop and walk a couple of times (only for about 30 seconds each time. My HR came right down into the 120's) When I got home, I realized that all of my sweat had turned to frost. I feel tough or something now. ha.

RUN, 45:00 (6:00am), 146bpm, 625cals
