A.M. Ran with Mike, then with the kids. Benjamin - 3, Jenny and Julia 2, Joseph 1, Jacob 0.5. Total of 12.25 for me.Mike and I did a pickup for 1.25. The target was to run 5:20 pace for 1 mile, then 5:00 pace for the last quarter. We did it faster - 5:15 through the first mile, then high 72 for the last quarter, total of 6:27.9. I was happy that 72 quarter came so easy, the entire time I was wondering if we were going to hit 75. But at the same time we passed another runner during the kick that was going around 9:00, and I could not tell at first if she was walking or running. So the ground was moving. I did a calculation - when you are going 4:50 you are moving at 10:26 pace relative to somebody going 9:00. That is, he is coming to you as fast as the trees do when you are running 10:26. If you slow down to 6:00, and he is still going 9:00, the rate of approach is 18:00 per mile. Even at 5:20 the rate of approach is only 13:05. Mike and I do not visit the 4:50 range too often due to the lack of fitness, so when we do we get to observe interesting visual effects.
