A.M. Did an odd workout. On Saturday during Benjamin's soccer game I noticed that the Foot Printers Field was not aerated. So that gave me an idea to run there. Jeff, Benjamin, and I drove out there. Then we measured a loop. On the first measurement it was 1626 feet. On the second measurement after the run, when we followed the path that we actually ran, it was 1633 feet. So I'll go with 1633 feet.
Benjamin ran the first 2.5 laps with us, then we sped up. He ended up doing 7 laps (2.15 miles) in 18:50 (8:42 average). We gradually kept speeding up until I saw my HR was 145 and our laps were in the 2:05 range (6:45 pace). I figured it was time for a mini-tempo, so I conservatively told Jeff to get my HR to 152 knowing that he has an overachiever tendencies. We ran the next 8 laps (2.47 miles) in 14:42 (5:56 pace). It felt hard. HR quickly made its way to 158, then spent a good portion of the second half of the tempo at 161, and hit 164 in the last lap, which we did in 1:46 (5:43 pace). Jeff's HR was also high - 176 when mine was 161, and 181 when mine was 164.
So something was odd today. I asked Jeff how hard he was working, he thought about 5:20-5:25 effort. Slower pace also felt noticeably harder, and the HR showed. So either both of us got out of shape fast, or there is something about that grass that we do not quite understand.
Ran the cool down. Total of 33 laps (10.2) in 1:14:14.
P.M. Wore Crocs. 2 with Jenny in 17:59. Julia ran the first 1.5 with us in 14:21. Then 0.5 with Joseph in 5:01. The foot felt good enough to try running 10 miles on pavement.
