Every cycle must have some low points... I got mine last week, on the 16-mile long run, when 12 was supposed to be at marathon pace (6:43). I was perfectly fine for the first 6 of the 12, and then I started to slow. Mile 7 was 6:54, Mile 8 was 6:51, and mile 9 slipped over 7 minutes. I called it quits and I jogged the rest.

I felt very demoralized, but it's not a huge deal. I'm now two runs into week 8, and I feel good. I will not have many marathon paced runs in the remaining of the training cycle, but I'll have one very long (14 miles), which will tell me my progress.

What went wrong? Who knows. It was warm (80s), but not very hot, I got a bit dehydrated, but not too much. My cardio felt fine; it was my muscles that seem to have given up. Too many miles? Dehydration? The oil change and tire rotation in the hot garage before the run? I will probably never know.

Week 8 (recovery):

T: 9 GA
W: 9 w/ 6 x 800 @ 5K pace
T: 6 R
F: 11 ML
S: 8 GA w/ 10 x 100 ST
