Hello, in my activities on Garmin Connect my "time in zone" (Heart Rate) has shifted up a zone. Not sure what caused it. I just went from a Fenix 3HR to a Forerunner 735XT on Friday, Sept. 2nd. I made 2 runs that day one with the Fenix (5 miles) then when I got the Forerunner I ran again (3 miles). I check my time in zone after every run because I'm training in my zone 2. So all of my runs since the Forerunner was in the correct zone up until this morning when I checked, zone 2 shifted to zone 3. I checked my heart rate zones in user settings under devices (Forerunner 735XT) and all the zones are the same as they were with the Fenix 3HR. Yesterday the zones were correct in "time in zone" but for some reason as of this morning all my runs with the Forerunner the zones have shifted. Wondering what could have caused this. I'm going try some other things, maybe reconfigure my heart rate zones in user settings. I plan to do some strength training at the gym sometime today and plan to run a few miles on the treadmill. All my runs thus far has been outdoors. If this continues I'm going to open a ticket with Garmin. Btw on Strava and Endomondo all my "time in zones"" are correct so this seems to be an issue with Garmin Connect.
