A.M. Ran with the kids - 4 with Benjamin, 3 with Jenny, 1.5 of it with Joseph. Julia ran 4 with Sarah. I have been thinking about quickness of muscle contraction vs force and decided to do a test. So I ran 7:30 pace for about 1.5 miles, and then picked up to about 6:15, and then to about 5:55. It appeared to me that the difference between 7:30 and 6:15 was mostly in how quickly I was moving my legs, but the amount of force I had to put into the step was not much difference. But 5:55 compared to 6:15 required a whole lot more force. Also, in terms of breathing, I was not breathing much harder at 6:15 than 7:30, but much more at 5:55.
P.M. 0.6 doing errands on foot.
