Anybody done 1 min on, 1 min off intervals @ vo2 / tempo? I dug out this session my old coach set me recently and managed 20 minutes with a NP of 104.7%. It was tough but not all out. Managed 2x15’ @ 90% afterwards during a heavy block of training too.
There’s no way I could hold a consistent effort like that for 20 minutes on the turbo. That’s just below the power I do on the road for an all out TT. Anyone have similar experiences, or know why I found that kind of session easier?
