Extremely Low Lactate Threshold Heart Rate (LTHR) Detected

Today I did a normal run with HRM strap on, and auto detect LTHR pop up the first time after the run, but the value was extreme low 65 BPM & Pace 6:04(min/km). How is 65 BPM even a value for LTHR? Anyone know what I did wrong? Or is it normal for the first few value detected usually a bit off, and will get better in the future run. Thanks.

This is my heart rate zone setting, I am using Heart Rate Reserve (HRR) ciq.forums.garmin.com/.../1369556.png ciq.forums.garmin.com/.../1369562.png

Same for me, must be a bug

Hi, was it happened to your first LTHR as well? what is your heart rate zone method? try to pin point the root cause.

There are a lot of threads on this issue. Some are speculating that the LTHR is simply missing a 1 in front, so the 65 BPM should be 165 BPM.

I saw the post about missing a 1 in front too, but I am still not comfortable simply assume that is the case. Thanks anyway.
