Garmin Connect Exporting Data

[DFinn32]

I have a Garmin Forerunner 235, which does the job. However, does anyone know how to export HR data from rides? I know you can export the GPS and view time in HR zones through Garmin Connect, however I like to do my own HR analysis, so would be great if anyone has any help here. Thanks.

On the activity page go almost top right to the cog icon and select "Export to TCX" and the data should be in there.

I also get the data if I do "Export to GPX", e.g.

      <trkpt lat="51.48028009571135044097900390625" lon="-0.1796971075236797332763671875">
        <ele>4.599999904632568359375</ele>
        <time>2017-06-22T08:33:09.000Z</time>
        <extensions>
          <ns3:TrackPointExtension>
            <ns3:hr>161</ns3:hr>
          </ns3:TrackPointExtension>
        </extensions>
      </trkpt>

The Forerunner records in FIT format. If you plug it into a computer, you can find the files in the Garmin\Activities directory. So you can just copy them from there.
Though depends on what sort of analysis you want to do, you may want to convert to another format. eg GPX or TCX or CSV etc. You could use GPSBabel to convert it.

You could try Golden Cheetah, it can do a variety of fancy analysis for heart rate etc. It should be able to import your FIT files.

Thanks both - worked a treat!

You've gotta love all those useless decimal places.  No wonder tracklog files sometimes seem bloated.
Given that the 5th decimal place of lat/long represents about 1m (broadly speaking) which already exceeds the precision of the GPS system, 29 decimals implies a positional accuracy (a yoctometre?) which I'm guessing could be sub-atomic.

Indeed, somewhere there's a senior developer pointing someone the manual for fixed point representation.

Float (IEEE754 Single precision 32-bit)

4.6

Most accurate representation = 4.599999904632568359375E0

Ugh.
