Upload GPX with Heartrate

[Christopher Brandt]

Hi there,

I'm uploading .gpx files created by Garmin that contain heartrate information, but Strava does not seem to be taking the heartrate data in. The documentation here says that Strava can import GPX 1.1 files with Garmin's trackpoint extensions v1.1. The trackpoint extensions include a <hr> tag for heartrate.

I've created a tool to upload gpx files using the /uploads API. Neither that API or the web interface (which is likely using the same API underneath) is reading the heartrate info.

Anyone have experience or suggestions?

I've already uploaded ~1000 gpx files and just realized the heartrate data didn't get in :-(

Christopher,

Are you qualifying the extensions? Here's an abbreviated sample:

<gpx version="1.1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xsi:schemaLocation="

Yes, the extensions are qualified. I'm using the file Garmin output. This only difference I see is the name of the namespace.

<gpx creator="Garmin Connect" version="1.1"

I'd just like to ask what GPS unit you're using, that is precise down to 28 decimal digits.
At this level of precision, you're ten million times more granular than the theorized size of quarks and electrons, so in my use case perhaps I won't miss a KOM by a rounding error.

That's funny, hadn't noticed. For the record, that workout came from my old Garmin 405, not likely accurate to much better than 5 decimals places.

Ran into the same situation.

Yes, updating the XML namespace schema worked! Change Garmin's exported GPX ns3 to gpxtpx. Now HR, cadence and temperature show up on Strava.

However, one other problem I noticed is that there is no "Lap" view in the sidebar for GPX files exported from Garmin.
