I missed yesterday's run. There was something about staying up till 1:00 AM working that made a 5:30 AM run near impossible. I slept plum till 7:00 and rushed to leave at 7:30. The other thing that made the decision to sleep in a little easier was the -2 F temperature with a windchill in the -20's. Running on 4 hours sleep I can do. Running a treadmill on 4 hours sleep is more difficult.
Today, the temp was even colder: -4 F. I finished up work by 12:00, so 5:30 was a little more do-able. So, I hopped on the treadmill for a 10 miler. I ran at about an 8:10 pace (7.4 mph) except for the last two miles which I ran at 7:30 (8 mph). My mileage will be low this week anyway, so I couldn't skip today no matter what. It wasn't as bad as I thought it would be. At 3.5 miles, I thought I was going to go crazy, but I just let my mind wonder and quit thinking about it and endured. It was funny that two other people came in the small hotel fitness center and ran and left during my run. They're probably more sane than me.
U2 seemed to make the time go by a little faster. But I do know now why 4 miles is generally my treadmill limit.
