I’ve alternated the training approach for my endurance rides. One block Balanced, the next block Moderate. That seems to work OK.
It’s at least partly academic anyway because most of the time I just do an endurance ride of about the right duration and about the right wattage and just let the workout go unridden.
Interesting post to read!
Newbie here to structured training and 6 weeks into TR.
Started at 171 FTP (which lined up to my recent ramp test), then after 4 weeks bumped to 184. Admittedly I was stoked and proud, but nervous as heck to tackle such a bump, specifically to sweet spot intervals. To my surprise I’m handling the new bump quite well! However now it’s predicting in 2 weeks it will bump to 204. I can’t fathom managing that bump in a few weeks.
I nearly died on my last vO2 ride at 184 FTP, should I organize my funeral for vO2 at 204?
No. That feeling is entirely normal for any VO2 Max workout worth doing. 
VO2max and high intensity stuff are not the prob.
Here is a sample of my calendar. I’ve got tempo ”endurance” and low endurance 3 days in a row. The 1:30h endurance is supposed to be 0.7 IF, according to my real life FTP it’s more 0.8IF. As i have heard in the podcast and as @kevistraining said it could be beneficial. Do you all think so?
It entirely depends on how well you recover and how well you can hit your intervals, because there’s no point doing interval training if you can’t go hard/long enough to get the intended stimulus to drive adaptation.
I know that at 57 - and without a long training history - I want/need my easy days to be closer to 0.55IF than 0.75IF, especially as AIFTP has set me an ambitious number and a gap from reality that I’m slowly closing. 
Be guided by recovery and RPE. If your endurance rides feel like tempo, they are tempo, and should possibly count as A Hard Day.
