So, these guys do 345-365 for a 20 min effort, 1900 for a 5s-something effort and yet cant even maintain 300 for an hour? I'm not gonna say you are wrong, because I bet these are your observations, but I still think something is off. A 20 min effort is a very aerobic effort, even if you have a huge W'. A 20 min effort at 365w is about 440 kJ and with great anaerobic capacity you might get 10% of those kJ from anaerobic processes. Thats 10%.
What you saying is basically that a 16 min 5k runner cant run a 1:30 half marathon. It does not make sense from an physiological standpoint.
There are 13min 5k runners that cannot go 1:30 half.
