Right now, the only way to see this info is to look at a completed workout or ride, in the “Power Zones” section of the data.
It would be handy to have a page that shows the Power Zones for the rider based on their current FTP as set in the app and web. This info can be useful for general info, planning for outside workouts and races and likely other purposes.
Additionally, including the Watts/kilogram could be interesting include on a page with this info. But this is likely a much lower priority than the pure power zones above.
