I have noticed that my heart rate zones do note change no matter which method i use to set it i.e. bpm, %hr max, %hrr or %lthr. I also find it frustrating that when selecting a method, i can see the set percentages for each zone but it does not show the corresponding HR range. Nevertheless no matter which method i use or by how much I change the percentage range, my zone 2 ends up being 112bpm to 129bpm. I currently have the %LTHR as the method, my current lactate threshold is 162, max hr is 185 and rest hr 44, so i do not think this is right. I have the auto detection HR and LTHR on. This issue impacts on the feedback received when when doing a run targeting a set heart rate zone and also when the activity is uploaded to Garmin connect. Has anyone come across the same? Any solutions?
