I’ve got this scheduled on my plan for today and the weather is too nice to do an indoor session that is not HIIT. I’ve only ever done this workout once, 2 years ago before I had a smart trainer and looking back it must have been dialed back as a recovery ride because it was all Z1 to low Z2.
What kind of structure would I be looking at for an equivalent outdoor ride (I don’t have a power meter so will be riding to RPE and HR), scrolling through the video it looks like 4x 6-8 minute blocks of Z3-Z4 (75-100% FTP)with 2 minutes rests at Z2 (50% FTP)?
