HR spikes mid run when running outdoors only.

HR spikes mid run when running outdoors only. My wife’s Forerunner 265S works OK when running on the treadmill, but gets a spike in HR mid run and her HR readings remain elevated till the end of the run. HR chart looks like a step: stable reading for the first half and +30bpm stable for second half of the run. This happens regardless of the distance 10mi, 5mi or even 1mi. We have tried using an Apple Watch and my Garmin 265 as comparison and the issue seems isolated to her watch. Is this an issue with the watch or with the latest software update? What should we do?

I'm glad that this seems fixed for now, but we are tracking a software issue regarding OHR spikes/drops. We hope to release a fix as soon as we can. In the meantime, feel free to view a couple…

This is 235 subforum, older model.

Check 265. There are threads about heart rate problem and mention update, so ye, probably it's software.

The issue got fixed by resetting the watch to factory settings and cleaning the sensor with alcohol wipes. Not sure if it got fixed for good, but the last few runs have been captured correctly.

I'm glad that this seems fixed for now, but we are tracking a software issue regarding OHR spikes/drops. We hope to release a fix as soon as we can. In the meantime, feel free to view a couple of the main threads that are affecting a couple of other models:

- She didn't say it was fixed…obviously wipes won’t solve a sw issue. It’s not happening for my runs, so it’s not affecting everyone with every activity.

Hi i do not remove the watch from my wrist, i just do a quick "technical" pause

This morning -5° Celsius

I can't explain the HR spike at 27mn, each time i saw these spikes it's around 25-35mn during regular run, no specific exercises or difficulties. Sometimes i saw this spikes 1 or 2 times later during the activity.

This bug has been escalated to the highest level. We have a fix in an upcoming software update, but I do not have a timeline for when it will be released unfortunately. I will update this thread once it's available. I'm very sorry for the frustration in the meantime.

I know that Elevate 4 is shared accross FRxx5 and F7/E2, software for this sub-component is also the same WHR/BMX 15.1.1/15.01.01, i don't know if Sensor Hub is concerned but same situation with version 28.10.

I encounter strange behavior too on my F7Xss 15.xx Public and now 16.xx beta.

Thanks in advance
