all garmin activities on a map

After further scouring through my data export from Garmin Connect (see https://www.musings.ch/2020/02/22/all-garmin-tracks-on-a-map/), I found ${username}_${index?}_summarizedActivities.json, which contains all activities I ever recorded. 😃

That one contains 468 usable startLongitude/startLatitude elements, which fits nicely into kml as Placemark and renders well on https://www.google.com/mymaps.

The resulting map:

all my Garmin activities anchored in a location, plotted on a map using kml Pacemarks

Which also works well zooming in:

Again, drop me a note if you feel I could help you with any of this.
