Interesting stuff. But this part does not compute:
“biggest” workout of his entire marathon training block — eight miles at marathon pace followed by one mile at threshold pace for recovery, times two.
By what definition is threshold pace slower than marathon pace? I know it can vary, but isn't it usually in the 15K-HM range? On it's own, 8 MP + 1 float recovery + 8 MP + 1 float recovery sounds like a challenging workout, but by no means impossible. On the other hand, 8 MP + 1 T + 8 MP + 1 T could get ugly real quick, if T is the standard tempo pace.
No need to nerd out about it. It says for recovery, so you know what it means. Could mean aerobic threshold though.
