Thanks, you’re right. I’ve got a 3.5 hour Z2 one, which is 9.3. Custom workout though, with sprints. I’ve got 4.5hr Z2 scheduled for 2 weeks, which is about 9, not really looking forward to that. I’d need to stop to eat, and not not sure how TR will react to that (I normally just ride these, and not try to do a workout). That much Z2 creates an incredible amount of very deep hunger and need to pack lots of PBJ sandwiches and fluids.
Yeah, It is actually > 16. Stuff like “Spanish” is pretty easy for me especially at those power levels and a considerably easier workout than I would normally do. VO2/Anaerobic short repeats are easier for me than steady state stuff. The 4x16 @ 106% in the polarized plan is murder and would not even want try. I might be able to do 2 of those, but 3rd and 4th would bury me. Considering my TTE @ FTP is about 35 minutes, it would all but be a major failure and would take me out for a week or more if I even tried to complete it.
