Currently at 4th week of POL Base.
AT is now trying to push me into 2x16min at 105% with 3min recovery (Cho Oyu, PL 6.8). This is also my current threshold PL. From previous weeks’ experience, this is going to be really hard. Plus after that workouts with 3x16min at 102% are waiting. In comparison, I think I can do sub-threshold Unicorn (PL 8.4) with less mental fighting. Actually neither workout is specific to my goals (ever growing medium intensity Z2 rides on flat terrains). Given choice, I do like Unicorn-like workouts better, though.
After high volume of Z2 and improving TTE for various durations, I am interested in raising FTP. So, here’s the question: should I continue following AT suggestions with suprathreshold or focus more in TiZ like @jarsson suggests?
