After playing in my city league basketball game last night, my knee was only slightly tender to touch and the pain I had been feeling in flexion wasn't present. Things were looking up, at least for running--we lost by 20 in the game.
This morning the scheduled workout was 6 miles, with the middle 2 miles at a Short Tempo pace, which I decided, with the help of the McMillan Running Calculator, is 6:30-6:45 for me. Considering the weather and my knee, I decided it would be a 4 mile run, with the middle two at a faster clip. This morning's temperature in Plymouth, WI is somewhere between the-hairs-inside-my-nose-have-frozen and I-better-get-inside-soon-or-my-you-know-what-is-in-serious-trouble. I took off for a one mile warm-up (ha ha) and clocked 7:00 on that downhill stretch. I could feel the knee at this point and was considering turning around, but by the time I was into the second mile, it was fine and didn't cause me any more trouble the rest of the way.
Just checked weather.com...it's -6 out. I don't put much stock in "Wind Chill," but for those that do, it's -26 with that.
