Heart rate gauge shows wrong zones

Hi, I have the Fenix 6X and train based on %LTHR. But when I run, the heart rate gauge isn't set to %LTHR and I can't figure out how to change it. I think it's still set to MHR. So for instance it will tell me to run at 135 BPM, and if I have audio it will tell me my range should be 130-143. But the gauge will show me in the 'green' from anywhere between 133-151, and then only beep to tell me that I'm leaving the recommended zone if I go to 152. My Z3 starts at 144, so the result is that I'm not the proper warning that I'm leaving the recommended zone.

Note that when I go to the Connect App, it shows my heart rate in the correct zones, but that doesn't help me while I'm running.

Does anyone know how to adjust the gauge to %LTHR zones? Thanks!

You can adjust this in Garmin Connect Web and in Garmin Connect Mobile in the Device Settings -> User Settings

I've already done that. When I view my run in Connect Mobile or Web, I see the correct zones. But during my run on the watch, the colourful zones dial along the top of the watch says I'm in the right zone from 130-150. based on my LTHR settings, it should be between 130-143.

Why does the watch "heart rate gauge" still think my Z2 is up to 150 when I already set it to 143?

I assume you have synced the watch after the Changes so that the new settings get pushed to the watch. Maybe the Graph is just programmed to display based on MHR, but thats a thing one only can assume as well.

Have you had a look at the zones on the watch to see if they are the same as Garmin Connect?

It may be worth checking if you are using sport-specific (in this case running) HR zones, or just the general zones.

I agree with the other posters - any zone changes should be made in Garmin Connect and synced to the watch, rather than being set on the watch directly.

yep, they're the same.

I tried both - I set a running HR zone just to see if it would change it.

Originally the watch detected my LTHR and then I changed the zones from MHR to LTHR. But that's a good idea, I'll reset the zones on the watch to the default and then change it in Garmin Connect, re-sync, and see if that works!

I haven't paid attention to the zones while running but I know that Garmin uses Max HR zones for many of their metrics, regardless of what you set in your profile. Perhaps the HR gauge do the same and always use your max hr to set the zones and not your threshold?

I think you're right and this is what I want to change. The watch is constantly telling me I'm in the right zone or high, but it isn't consistent with its own recommendation. for instance, the recommended run is at 135, the audio says 130-143, and the gauge says 130-150. This makes no sense.

Agree. I often do base runs with the majority in Z2 and rest in Z3 but the watch still says it was a tempo run afterwards.I will look at the gauge next time, my zones are set using HR reserve. I don't know how accurate the LTHR estimation is but know my resting HR as well as MAX.
