N) 14 miles with 3100+ ft of climbing at average pace of 8:36. Thermometer read -18 with wind chill. I walked out the door for this wanting to challenge myself and raise the bar on what I think cold is. After about 5:00 I settled in and felt quite good, the cold was never a bother.
With the morning run: 18 total and 3900ft of climbing at an average temperature of -20 something.
