Download GPX
Paste a Strava, Komoot, or RideWithGPS URL and download it as a GPX file.
Send it to Garmin Connect: open the course importer, then drag the file you just downloaded onto its drop area.
Supports Strava (routes/<id>, activities/<id>),
Komoot (tour/<id>?share_token=…), and
RideWithGPS (routes/<id>, trips/<id>).
Public items only. Strava activities usually lack elevation; everything else has it.
