I’m on week 8 of this plan and I found there was a bit of a step change in week 5 regarding the Z6 stuff ramping up to 150% of FTP, I quit my first ever workout in this week after thinking I had been making good progress to that point, I failed the cruise intervals in week 5 also, and then missed two more due to work/holiday and the inflexibility of the plan so that was a poor week for me, I was dreading week 6!
I’ve completed every workout since, although missed a few stars on more high power Z6 stuff in week 6 and 7
I’ve completed the AC workout for week 8 and took every star on that one, and feeling confident of completing the 4 remaining workouts without missing any more stars.
Currently 41/49 workouts, 672 stars. 876 mile, 41h49m, 28780kcals!
Best of luck with the rest of your plan!
