I keep an eye on the colour of the lightning bolt power symbol in the HUD (top left) to try and make sure it stays green as much as possible so I am in the productive zone for most of my ride. Up to now, the symbol changed from blue to green at 100W, but today it didn’t change colour until I went over 102W.
Can anyone explain this?
(just fyi, I am typically running at 1.2W/kg - I am a beginner and quite an old man!)
Your FTP will determine when the game thinks you are in a given zone, so if that changed, that could explain it. Details about how that setting is managed:
Riding at tempo pace all the time will most likely result in a fitness plateau in a matter of months. If you want to see if your training is productive, I recommend pairing your Zwift account with intervals.icu and look at the fitness graph so you know if you are in the “grey zone”. The Zwift fitness tracker does not show this information.
Thank you for explaining.
