Sweet Spot Progression

Here was the post I was referring to.

Targeting 200 watts for 1 hour

I’m absolutely not having a go at your fitness, we all start somewhere and as someone coming back from an enforced hiatus I have a lot of work to do! But it does show that regardless of the number, overreaching on an FTP test (as you appear to have) can completely throw your training zones off. You mentioned that you are training in zone 2 power for endurance, but if you are training at your ‘set’ FTP rather than your ‘achievable’ FTP how do you know you are actually training in the correct z…

If incorrect as it appears to be your tempo and or sweetspot is actually going to be threshold. Endurance is going to be tempo etc. Seems out if 20 minute best is 20 watts lower than your set FTP

What is your power measuring device and how have you set your FTP?
