HR Zones misconfigures repeatedly

Hi there,

   It has happened 3 times now. I configure my default HR Zone to HRR%, changing some zones 60%, 70%,  80%  90% and 100% to other values (60%, 70%, 78%, 86%, 100%). And it works great, the first time. Then, next run activity (I am a runner, no cycling or swimming activities), HR zones in exercise are reported again as the 60, 70, 80, 90 and 100.

   Looking at the configuration I can see that my default HR Zones are correct... but then, besides the default zones I configured I can see there is a configuration for HR zones specific for running. First time I thought that maybe it was me messing with the configuration, weird because it worked fine the previous activity. I deleted the running HR zones leaving only the default HR zones. Next run it works ok. But next after that, zones are reported again as the 60, 70, 80, 90 and 100. I look in the configuration and here it is in the configuration: HR zones for running with the default values, again. This time I do a "Reset zones", delete everything and configure the default HR zones as I want.

   Next run (today) it is ok. But now I check the setup and I can see a new specific Cycling HR zones. I am 100% sure I never created HR zones for cycling. I don't know where that is coming from! There is something wrong with the way the watch handles HR zones.

   Next time I will try to setup all the zones (Default, running, cycling and swimming) the same, and see what happens, because luckily I don't need different zones for different sports. But it is getting annoying. Any insight?

   Best,
   Kurt.-

  • There are some settings for automatic updates of your zones. If you enable that, Garmin will use the percentages you mention. If you switch off the automatic setting, they will stay as you have edited them. 

  • I checked my own watch. I have the zones set up based on Max HR, and my edited percentages never change.
    The zones for cycling and running are just a copy of the general zone unless you make changes to them.

  • Thanks for your reply. What automatic setting is that? In "Auto Detection" I disabled "Max HR". I have "Threshold" on but I think that until the next update Lactate theshold detection is not working (since I have this watch it has not detected any new LT), and anyway, my zones are based on HRR% not LT%. Any other thing I may have missed?

    In my case the zones for cycling and running that appear spontaneously are never a copy of the general zone. They always show the default values for zones, not the values I edited in the general HR zones.

  • It starts out as a copy of the general zones, but it seems like there is some automatic update at play, and that will update only for the relevant sport. Does the watch ask you if it should update the zones after your runs? I have auto detection of both lactate threshold and max HR.
