Temp of 11F and windchill of -7F when we started the run. At the finish the temp was 7F and a windchill of -12F. Feet got very cold, face a bit chilly, otherwise was toasty warm. Wore underarmor, long sleeve tech shirt and Colorado jacket, tights, tech undies, addidas shell, smart wool socks, gloves and mitten shells.
Felt good, no aches or pains.
