I’m currently following 80/20. Doing the same as @sinbad, designing my own. Low intensity rides outdoors and indoors. Augment about 1x per week with a TR VO2max or threshold workout. It would be easier if TR had a polarized plan.
I may transition to TRs usual Sweet Spot plans at some point next year, for specificity reasons i.e. to get rides under my belt at sweet spot intensity.
