Inacurate heart rate

Former Member over 7 years ago

I went for a run with my Fenix 5 watch. I started the run activity properly and the activity was recorded as per screen shot. It shows an average heart rate of 163 bpm. Now when I go onto the daily heart rate screen (iOS app) then the run is properly tagged with the green runner icon, but the heart rate is totally wrong. The graph shows a very low heart rate from 10am to 5pm. At 5pm it comes back to a normal rhythm.

Could anything explain why the data shows fine in the Run Activity view, but not in the Daily Heart Rate view?

Thanks! ciq.forums.garmin.com/.../1271641.png ciq.forums.garmin.com/.../1271642.png

Yeah that's weird. I've not come across that before?
Did you use a chest strap for the run or the optical HR of the watch?

No I am not using a chest strap. So that was the optical HR monitor.

I also had a couple of times the watch becoming unresponsive before an activity, so I I has to reboot it. But cannot recall whether that happened on that occasion.
