Background

When you bulk export Strava data you may receive a zip file of a number of different file formats:

• .gpx
• .fit.gz
• .tcx.gz

Annoying. To get them all into gpx format follow these steps.

Method

Extract the .gz files

For Linux - Extract, or decrompress, .gz files using gzip -d filename.gz. Use -dk to keep the original .gz file.
For Windows - Extract .gz files using 7-zip. 7-zip allows you to select all files and extract them all in one go.

Convert .fit files to .gpx (requires Python)

Install the fit2gpx python library:

  pip install fit2gpx

Or using pipx:

  pipx install fit2gpx # or,
  pipx inject [environment] fit2gpx

Note fit2gpx can also do the extracting in step 1 if not done already (see documentation.

Create and run a python script:

  from fit2gpx import StravaConverter
  DIR_STRAVA = 'path/to/strava_bulk_export_parent_folder/'
  strava_conv = StravaConverter(
      dir_in=DIR_STRAVA
  )
  strava_conv.strava_fit_to_gpx()

Converted files will be in the activities_gpx folder.

Convert .tcx files to .gpx (requires node.js.)

Download/clone tcx-to-gpx-converter.

Type npm install from the clone folder's location.

Copy the tcx files into the input folder.

Type node convert.js.

Converted files will be in the output folder.
