Garmin 920XT vs Garmin 910XT - Triathlon ShowdownTo enable beat by beat recording on the Garmin 920XT (or Garmin Fenix3 or Forerunner 620 or 735XT, 630 or most newer models) you need to do 2 things

1. Enable per second recording (NOT smart recording)

2.  Open (this) zip file and extract the file “” directly to your 920XT in this folder: :\GARMIN\NEWFILES Sorted.

As of July 2016 this will NOT work PROPERLY with optical HR.

Now; how you plan to look at the data and/or use it in your training is another matter entirely 🙂 Maybe with Firstbeat ATHLETE software? Or Sporttracks using the Garmin FIT Importer plugin and/or Liverecording plugin? Here is a link for the Garmin Forerunner 920XT Review.

Sorry what is the benefit of doing this? It feels like I’ve come in half way through a conversation!


Ah so gives more meaning to the “Recovery Good” and advised recovery times? Is there any downside to this such as increased battery drain/usage? Im trying to work out why this isnt a default!




Is there a way I can use HRV recording with the 910XT? I have tried the above, but it seems to be different. I would like to use it in FBA.


I followed the instructions, but can’t see a difference like a HRV Menu . I installed the HRV App
via Connect IQ. But this app doesn’t offer log data 🙁


THX, how can I see if the recording in the fit file is working ?


I am using Rubitrack 4, because I am using Mac. It is supposed to show HRV as well since the latest release. I just tried uploading the FIT File directly not via Garmin Connect, and it showing a HRV value. THX.


Is there a way to use Garmin Connect and get HRV data ?


Just a note: That does work for a Fenix3 as well!

Thanks a lot.


Late, but still good. Thanks for the link to the file. Helpful.

RUNALYZE ( supports reading HRV data from FIT files and shows several values and graphs like R-R intervals and a Pointcaré graph


hi, when I copy the file on to the newfiles folder, it doesnt stay there. each time I reconnect to the 920xt the file is gone. anyone else have this issue?


thanks for response, ok i see, that would make sense. must be something else that’s an issue. i enabled per second recording also, still getting wonky HRV results. cheers


thanks, ok sure. i recorded these two right after another, the HRV data is coming out very different in each. (Actually how do I attached files here – or want me to email them?)

btw – I use Kubios software. so my process is:
setup Garmin – install hrv settings FIT file to ‘newfiles’ folder, then I set up recording to ‘per second’.
I then record 1min sitting/1min standing by using the indoor run activity – so it doesnt try search GPS.
I then upload file in to kubios, grab only the first minute for analysis. data is widely different every time.

How do you turn this off once it’s on? The file sizes are way too big for longer runs…takes upwards of 5-10 minutes just to transfer from watch to phone over bluetooth.


How could I turn it off definitely on the Fenix 3 ?


I can’t find the fit file. It has been “abzorbed” by the watch and transformed into a setting somewhere.

Is there a possibility to activate the Beat-to-Beat-Recording on the Vivoactive HR using a Heart-Strap?

J Bussmann

I’ve tested this approach on a Forerunner 230 (with chest heart monitor) although this watch officially does not support HRV analysis. If you copy the into the Newfiles directory, R-R intervals are recorded in the .fit files coming from this watch. It might therefore work for other watches that do not officially support HRV measurement (including the vivoactive HR).
