I just started a power/power olympic 1 plan this week. Week. Last week I tried the CFo2 workout to see how it syncs with Zwift. It synced wonderfully. My FTP is set at 225 after a 20-min Zwift test. I had really hard time with the intervals at 280 and even with the 30 min zone 2 after that. Today during my zone 2 (supposedly 180w) bike workout my heart rate was in the high 150’s. It definitely didn’t feel easy. According to TP calculation of my 80/20 HR zones. In zone 2 I should be between 132 and 147 which sounds more like a zone 2 to me. So my question is, should I adjust my FTP so my zone feels more like a zone 2, should I do HR zone for easy workout? I know zone 2 in the 80/20 plan should be a bit challenging but I’m afraid that if I stick to those power zone I will overtrain. Any advise would be appreciated.February 17, 2021 at 5:03 pm #10505David WardenKeymaster
Thanks for using our plans!
First, let’s pause at “I had really hard time with the intervals at 280…” If your FTP was 225, your 80/20 Zone 5 starts at 248. The highest intensity our plans would provide you is barely north of 248 watts. 280 is 120% of your FTP, we won’t prescribe anything like that.
Your Zone 2 indeed starts at 180, so I can’t fully explain why you are seeing 280 at one end but the correct Zone 2 of 180 on the low end. Maybe send me a screen shot of your Power zones within TP?
To answer your direct question, you can always use Zone 1 when Zone 2 is called for. The division between Zone 2 and Zone X (the threshold between low and moderate intensities) in the 80/20 system is empirical. The division between Zone 1 and Zone 2 in the 80/20 system is an estimate. Matt and I just made a best guess on where Zone 1 ends and Zone 2 starts. There is no empirical data for “low intensity” and “really low intensity.” Therefore, high Zone 1 is still low intensity, and qualifies in the 80/20 system the same way as Zone 2. Feel free to hover in Zone 1 when Zone 2 is called for, and as you get stronger that Zone 2 won’t feel so hard.
Finally, I’d use Power over HR if you have Power. If you let yourself drift down into high Zone 1 power, that HR will probably match your Zone 2. Power should be primary and HR a distance secondary.

how can I send you screenshots?February 18, 2021 at 5:53 pm #10532David WardenKeymaster
Directly to firstname.lastname@example.org. However, on reflection, I think an even easier method would be to link your TP account to mine and I can look at your zones directly.
Follow this link https://home.trainingpeaks.com/attachtocoach?sharedKey=OKYJVWHNFAPPG and let me know when you have done it, than I’ll take a look.
