And that’s what I like most with the new polarized plans: they are the new best way to adapt your own training with. I posted this here https://www.trainerroad.com/forum/t/polarized-training-plans-are-here/55844/338?u=huegelreiter.
I take the MV Plan, use the VO2-Max session as prescribed with the smart trainer, ride the endurance sessions outside and add Zone 3 (i.e. Tempo to Sweetspot) according to my needs. Would it be Winter still, I’d use the Threshold Long Interval sessions either also as prescribed or transform them on the fly towards a Sweetspot or Tempo Session (easily done with the difficulty setting in the app).
4 days per week from the plan leave enough space to add 2 strength training workouts per week.
