I made the switch in week 6, so basically 2 weeks into the second block. It was a bit too late for me at that point, I mean, I got though the rest, but it wasn’t pretty and I was carrying a ton of fatigue exiting it. I had also never done long intervals above threshold and I crushed myself on those.
Next time through I will probably do one of the following:
- Do two highest pri workouts on Tues/Thurs and low pri as optional on Friday.
- Do the lowest TSS workout (but not the vo2 one) on Saturday morning and do a bunch of z2 after, and do the other two workouts on Tues/Thurs. Saturday would probably not be a 3-4hr day though as I’m sure I would be feeling a little toasty after the workout.
I think my FTP stayed the same coming out of SusPB, which is probably a decent outcome considering how I felt. But I feel like it really payed off later in the year with better fatigue resistance, sustained super threshold efforts, decreased RPE around threshold, and handling sustained high power and surges in zwift races.
