4×1200 with 400 m rest. Plan was 5 or 6. The first two went just the way I wanted. Then, an atrocious one, without any change in effort or the way I felt. I was so upset that I was going to quit right after it, but after a lap jog, did another one out of an experimentalist's interest. It was just as bad: 4'07 4'11 4'24 4'25. I went home.
I was not tired or feeling particularly interesting. My best guess is that the effects of rogaines are somewhat cumulative; I did not see this drop-off in speed after the July one, but maybe two rogaines in 7 weeks start to add up to some dead mitochondria. My next best guess is that it has something to do with all the interesting pharmaceuticals I have been trying in the past couple of weeks (all legal, in case you wondered).
