I have owned a smart watch for a while and use it to record my runs. I figure it would be pretty cool to see a personalized heatmap of where I run the most.
Garmin connect has no bulk export option, but Strava does!
Bulk Export
As of May 25th, 2018, Strava provides the option to export an archive of your account.
Your data archive will include the following:
A zipped folder with all of your activities in their original file format.
-
Python installed locally
-
A Strava Account
You can clone this project to generate your own personal heatmap.
1.) Bulk download your strava data. Once downloaded, unzip strava bulk export.zip
2.) move the contents of strava bulk export/activites into the projects activities/ directory
3.) Some activities may need to be unzipped instructions for file types
4.) Pip install required packages
pip install gpxpy
pip install geojson
pip install fitparse
5.) Before you will see any heatmaps you need to convert these activites to .geojson and combine them
6.) This can be done from the UI by running an instance of the express server
7.) Start the express server running the command node express/expressServer.js
8.) In another terminal run npm run dev to run the website on your localhost
There are various activity types. In my case I have .fit .gpx and .tcx
Some of the files may be gzipped.
// unzip all .gz
gunzip *.gz
Note
If some of the .fit files are failing conversion. It may be because they should have been named .fit.gz but are named .fit in the export. Renaming those files and unzipping should fix the issue.
Depending on how many data points are being drawn, the browser may kill a memory heavy tab. Here are some optimizations:
- Reduce the coordinate precision to 5 decimal points GeoJSON Minify (very minior loss in accuracy)
- Reduce the timeframe to not include all activites
