Yesterday I completed Taylor -2. My question/concern is my exertion was not what I expected. I maintained my power target of 120% of FTP during each of the 30 second intervals (candence ave during interval 105-110). Knowing this was a VO2 Max workout I anticipated higher elevated HR rages which I just did not see. My max HR rate is in the high 170’s (I’m 54), but I never went above 145 bpm, which was surprising to me. I feel my ftp number is pretty close, just want to make sure I’m maximizing this type of workout, it was my tough workout of the week. I was mentally prepared for a difficult workout, but didn’t feel like I maximized it. For what’s it’s worth I’m on a Kickr in ERG mode which could have something to do with this?
