Currently using an old forerunner 305 and a Edge 810
I'm sure when I first got the 305 I had Time in Zone (heart rate) on the Training center.
Whatever, I can now get it on Strava, just not on Connect.
Thing is, its a premium (subscription) item on Strava.
Any other Apps (windows 10 or Android) that measure TiZ as I'm considering starting a HR training program.
(Obviously the 305 may be on its way out, so with such 'basic' functionality not available on GC, I may start looking elsewhere for its replacement.... Might even start using the fitbit/phone and dump the 305)
