Notes
Base temp = 0F, -18C
Windchill = -20F, -29C
First 10 minutes were the worst - mentally had to push myself. After body warmed up a bit, I was fine the rest of the way (though it was still cold). Wore the Yaktraks ice spikes for shoes, though not really necessary today.
Didn't feel like I was running as fast as the calculations say I did. I felt like I was running sluggishly.
Good news: probably the coldest conditions I'll ever run in! And I did it! It can only get better!
