This is actually a lot easier plan than what I recalled. One only needs to put the painter suit on for part of the workout until you hit week 3. Easy enough to do in TR by either adding some extra time in Z2 via the workout editor, or selecting a short z2 workout and doing it directly after your regular workout.
This is very much setup for one to peak somewhere after the 5 week mark. Reading it myself I don’t think it’s sustainable for more than 8-10 weeks as it’s a LOT of work.
Definitely READ THE WHOLE PLAN.
