A.M. Started with Ted, Colby, and Jeff. Ted and Colby turned around 3 miles into it. Did explosions. Two fat miles. First in 5:56, second in 6:05. A change in the respiratory rate at 6:00 pace. Down to 15 from 17 breaths for 100 meters. Total time was 1:17:03 for 10.1.
Took HR a couple of minutes after finishing the run. The last two quarters were 89 and 88, so around 5:55 pace. Interesting difference vs Jeff. My HR went down to 78, while Jeff's was still at 111. I was at 1.62 of my resting HR, while he was still at 2.05 of his resting HR. We estimated that mine dropped by 48% in the same amount of time that his dropped by only 36%. His HR at that pace was about 20 bpm higher than mine, even though the pace was easier for him in almost every regard - percentage of max HR, respiratory rate, muscular effort, willingness/ability to talk, ability to accelerate off that pace, etc. The only questionable aspect is sustainability. I might be able to sustain that pace for longer due to larger fuel reserves. But fuel aspect aside, the pace was easier for Jeff in every way. Nevertheless, I was recovering a whole lot faster.
Shortly afterwards 2 miles with Benjamin in 17:33, and 2 with Jenny in 18:58. Julia ran 1.5 with us in 14:23.
