I’ve had a Garmin running watch (Forerunner 620, great watch!) for quite a while and ran a lot with that watch. Sadly, Garmin Connect is lacking an “export all” feature for your runs. We will use garmin-connect-export to download all our runs and visualize them with Matlab to obtain a heatmap-like summary of the most frequent routes we’ve been running.
