Like most private employers, mine does not give Presidents' Day off. That wouldn't make any difference in terms of working out, of course.
The plan for the day was to run 10 easy miles. My older son N had the day off, but my wife dropped him off at a Lego camp at the local science museum, but as always, J was the limiting factor, and I didn't get him off to preschool until past 10:15. I had stuff to do, including picking N up at 3:30, so I decided before getting on the treadmill to trim the run length to 8 miles.
However, when I got to the gym, all of the treadmills were being used or in need of service. D'oh! Well, I could use some more leg strength, so I got on the stairmaster, set it at level 8 (out of 20), and started climbing away. Naturally, after just a few minutes on it, I noticed that a treadmill had opened up.
I got off the stairmaster, grabbed the treadmill, set the incline to 1%, and started running at an easy 8:57 pace. For the first four or five miles, I read a few chapters from Absolutely Small: How Quantum Theory Explains Our Everyday World. I actually took a year of hardcore quantum physics in my sophomore year at Caltech, but I remember very little of it. This book is written for mathematically literate non-science majors, so there are a few equations but it's mostly descriptive. Now I understand why cherries are red and blueberries are blue!
When I logged this run at Fitocracy, someone left this comment: "Also, you read a book on quantum mechanics while clocking an average pace of around 8:30m/m? Can I give separate props just for that?"
Heh heh. Actually, math/science seems like a pretty good thing to read while running on the treadmill. You can stop to ponder the math in your head, which is a pretty good distraction from the tedium of being on the treadmill.
Anyway, splits were 9:04, 8:56, 8:57, 8:56, 8:48, 8:34, 8:07, 7:19. Heart/lungs felt really strong throughout, though of course the last mile was a bit taxing. I could have carried a conversation easily for the first five or six miles.
My right hip did feel twingy during this run, so afterward, I used the foam roller. OH MY GOSH, that thing is incredible! I have to get one for myself . . . .
