Wed 2/15 - PM 60 minutes incl. 4k progression, 10x200

First track workout since the latest comeback from the calf travails. Since it had been feeling tight during the day the past two days I had some concern, but no issues at the pace I was going. Originally this was going to be straight leg prep, decided to make it a mixed session instead. Original plan was to start the 4k at a reasonable and modest 90 sec/lap and cut it down a couple of seconds at each kilo. With no sense of pace whatsoever, I instead hit the first 200 in 43, 400 in 87, and decided to start the cutdown from there. Which meant finishing at 80, which was almost but not quite biting off more than I could chew. Km splits of 3:37.2, 3:33.3, 3:26.6, 3:20.5. Focused on staying relaxed and not overdoing it, as ever. After this, 5.5 minute jog recovery then into "glorified strides" or so I was telling myself. Hitting the button but not checking numbers until afterward, trying to run on feel and keep from going over the line. Interestingly and happily, both the reps and the recovery intervals of the last five were all faster than anything from the first five. First five 37.4-38.1, recoveries avg 65, second five 36.9-37.3, recoveries avg. 61. Relatively short warmup and cooldown.
