Hi - I've recently got the Fenix 5 so may be doing something stupid, but I set my HR Zones manually and saved them via Garmin Connect App. I set HR Zone 5 as 179 - 190 (190 being my HR Max). I also set them for the RUN section.
When I then went for a run with my Fenix 5, all my run activity shows as occurring in HRZone 5 (> 156 bpm). But 156bpm shouldn't be the floor for HR Zone 5, it should be 179. Is the Activity not using my custom HR Zones and if so why ever not?
Where does activity take HR Zone data from if not from what I set via the Garmin Connect App?
Thanks in advance for any sage advice.
Andy
