Another question: Did he mostly just increase his volume without changing the regimen much at all?
Specifically: He shifted from 45 minutes/wk of Z5 to 40 minutes/wk of Z4 -- although, because of the increase in total volume, the percentage to the total changed substantially. But he added 11 hours a week to Z1 with only a 1 hour reduction to the total of all the other zones.
Another interesting thing: he decreased his time in Z5 (95-100% MHR) while adding substantially to Z3 & Z4 (85-95%MHR). It seems to me that Z3 & Z4 might be the sweet spot for high output cycling since nobody can really maintain Z5 for long...
