I have known T-Will for 22 years and used to run against him (never beat him!) so this training log comes as no surprise to me. I have seen this kind of thing from Todd before.
One thing that stands out for me is that very little (maybe none!) of the training was done at 42:22 pace (which is 4:31 per 1600). Nor was any of it done at 27:31 10k pace, nor the pace you would expect to do in a 12k WCCC type race.
The intervals were done much faster, like 64 per 400 at the slowest. The LT runs are done at what rec runners would think are too fast, but 4:45 is very reasonable for a guy who runs 5k at 4:16 per 1600.
SO the intervals were done around 60-64 a lap for 800-1600 reps, the LT runs at 4:45-5:00 and the base runs were done around 5:40-50 a mile.
Now that I think about it more the 10 x 1k was done at exactly 10k pace.
Anyway, my point was that I often see posters decrying that you must do a lot of race-specific training pace-wise and I always think, "Why?"
You want to train your VO2max, or your LT, or your slightly slower stamina (10 mile, half-mar, mar) ... so that doesn't mean you train at EXACLTY race pace.
