A.M. Ran with Jeff and Josse. Jeff and I did an interesting workout. The target was to go 73 seconds per quarter until I could not hold the pace, then once the failure became obvious finish at the closest quarter mark. The first quarter was right on target - 73. On the second one Jeff put a bit too much pepper on my plate - 70. No wonder it felt so hard - I began to think wow, my anaerobic capabilities are so bad that I can barely make it to 0.5 doing 73s? Hit the 0.625 mark (a bit over 1 K) in 3:00, that was good. Then 3:37 at 0.75 (74). Around that point I started falling apart. No heavy legs, just all of a sudden cannot go, and do not understand why. That was not good. Next quarter was 78, stopped at the mile in 4:55.
What was interesting about the experience is that the boundary between, well, I can do this for a while and no this is not sustainable for more than another quarter was very thin. Which is expected when you do purely aerobic training, and is actually good in the marathon because the moment you start running too fast it hurts enough to alert you to the problem. With some anaerobic training I could of course train myself to sustain 73s for longer. But that would do me no good in the marathon. I want to be more aerobic at that pace, and sufficiently aerobic at 5:00 pace to make it through the 5 mile tempo. How do we do that? Big mystery, exciting mystery.
Here is an idea - find out a way to shut down the anaerobic gear without shutting the nervous system down with it, and do some high volume speed work as fast as the aerobic gear will let you.
For the rest of the run we ran easy with Josse and had her do 2x100. She did the first in 16.4, and the second in 16.6. Dropped Josse off, went around the block twice while Jeff went to the bathroom, then ran another 4.25 with Jeff. Total of 15.05.
