This is Zone 2 from my understanding (Tested since 23 October Last year)
It is the point Between 1. Fat Oxidation starts to drop, 2. Carbohydrate Starts to increase.
I’d agree with this, easily riding around 3 or 4 hours at the upper z2 takes its toll and especially if you expect to knocking out very intense workouts either side of them.
In isolation maybe, as part of plan for someone on limited hours that includes regular hard workouts, definitely not easy.
You constantly hear this narrative from a few here and its nonsense.
Statements like if you cant ride 3 * 20 @ FTP then your ftp is overstated.

This is a great point. .75 IF for 15 hours a week can be pretty tough to do week after week, usually leading to some pretty deep fatigue and takes away from ability to do intervals. Sure, go do a 3-4 hour ride at .75 3-4x a month, but day in and day out .55-.65 IF is much more sustainable.
Yep, but then I ride ultra distance, where 15 hours is small potatoes when it comes to event duration.
Hehe, ok. That is another ballpark ;-).
Should be great when you have endurance like that ;-).

After months of training, now I can do 281W for 90 mins (Tempo) - I think I can do longer but have to gradually increasing. (The load is high for my fitness now)
Fatmax from last year test was 158 bpm. Today’s ride mainset is avg 161 bpm.
Even HR is higher but I’m feeling better. 2-3 years ago 280W was my FTP. Now Garmin detected current FTP 324W but maybe already higher because I did not do 20 mins intervals much.
