This is a minimal Version of the 80/20 Run Zones data field to provide legacy support for older watches with limited memory size like Fenix 3, Forerunner 920Xt, ... This will only record and show your 80/20 power zones. Individual functional threshold power can be set for running and cycling. The data field will automatically choose the FTHP from the current type of activity. Note that this requires you to set an individual heartrate for cycling in you watch user settings as well.
