This morning I returned to the track for another go-around with 1000 repeats on five minutes. I imagined knocking this workout out of the park after five days worth of easy running, which meant finishing all 10 repeats while working down from 3:20 to 3:15.
3:19, 3:19, 3:16, 3:17, 3:16, 3:17, 3:16, then a last 400 where I ground to a halt midway through the curve to start a second lap. Yeah, that's only 7.
What happened? I was simply done. The legs still felt good, but the lungs started working too hard, the system felt too stressed, and I just felt like I was falling off the knife edge when I started forcing myself through the second 400 of the 8th repeat. Up until that point I had been feeling fine and smooth, with a heart rate in the low 160's immediately after each rep which dipped down to 100-108 after a minute. Things just changed quickly and I bailed out. As I'm finally starting to understand, Lydiard's coordination phase is more about getting the legs and body feeling sharp, and as I was digging in on the eighth repeat I felt like I was crossing the line into putting the hurt on myself.
Am I training to quit? That's been nagging me a bit, but I have to put it out of my mind at this point. I've grinded out my share of runs, especially long runs and back to backs this build, and it's time to back off and hopefully reap the benefits rather than giving in to the temptation to keep punching through the last round. The days where I've pushed through the final repeats have found me generally dragging my way home on the cool down and feeling stiff an sore the next day. Today the legs came back quickly on the mile home, and it was difficult to not extend the cool-down a few miles. I thought better of this when I remembered Mystery Coach's meager mileage target for the week.
Training: 9 miles, 1h5m, 7x1000 on 5 minutes at 3:19, 3:19, 3:16, 3:17, 3:16, 3:17, 3:16
