Thanks Dada. That sounds pretty logical. Indeed, I have not topped out with VO2max, as evidenced by my recent Z4 work,I think.
This endeavor will be an exercise in recovery.
So the short is increase speed at low effort. My experience shows that multiple weeks at AeT will lead to overtraining. My goal is to stay in the recovery zone and Z1, with occasional bits of Z2. I hope that will be sustainable.
That doesn’t change the training program much. So, thanks for advice.
My future focus is mainly on fine tuning recovery and maximizing VO2max. I plan on doing the into to skimo plan.
