Heart rate monitor or wrist monitor?

Hi guys

I ran a half marathon yesterday and from the start my heart rate reading on my watch seemed way higher than normal for the pace I was doing and it stayed higher throughout. I felt fine though as if the reading was way too high and inaccurate

Now I’m wondering whether for some reason the watch was taking my heart rate data from the wrist sensor rather than the Polar H10 I always use and was wearing, hence the possible inaccuracy?

Is there any way that anyone knows of that I can go into the Garmin connect activity or elsewhere for the half marathon and see from which source the heart data was collected from?

many thanks

Generally speaking, anytime an external heart rate strap is paired and active and being used for a specific activity, the wrist-based HR function is not active. So - you'd have to check when you're starting the activity, that the Polar HR strap DID in fact connect and was active, etc. I've not seen a way to look into an activity after the fact to determine the source of HR data, whether it be strap or wrist optical HR....

I believe some sites, such as FIT File Viewer will do this. Look at the product number in the device_info section.

For example HRM-Run is product 2327

Can anyone use this FIT file to check? Can I check yesterday’s run? Thanks

Yes. FIT File Viewer is a web site and should work regardless of what computer you're using. Click on "Open Fit File" then upload the fit file you want to check.

Actually if you view the activity in Garmin connect is the respiration field only present with activities where a chest heart rate monitor is worn??

I’ve been for walks where I haven’t used the H10 only wrist monitoring and respiration isn’t there?

Connect your epix to a computer using the supplied USB cable so that you can browse to your device using file explorer.
On your computer go to to FIT File Viewer
Click the "Open FIT File" button
On your computer browse to the folder EPIX > Internal Storage > GARMIN > Activity.
Select the fit file you want to upload

Then as above look for the section labeled "device_info" then expand it to view the product numbers.

If the H10 was being used during the activity to record your HR, then it should say manufacturer Polar followed by the product number.

OP can also download the fit file from connect without connecting the watch to the computer.

Not that the second way is difficult or complicated...just giving an alternative to not remove the watch, etc etc

Thanks so much everyone for all the advice. I’ve looked at the relevant fit file and it says this under device info. No mention of Polar specifically but an ant plus connection which polar uses? Is this the external HR? Thanks
