I find the Garmin Connect UI frustrating when it comes to rendering tracks: way, way too little screen space dedicated to the track.
e.g. https://photos.google.com/share/AF1QipMHDERDPAS7ZNjkd4SjIYEMJIXqtp_qKXEC3olBWOaR3vTHjLy8Ej0Zj0Nhs99Ubw/photo/AF1QipNH0h3tRd8HiHmO4knRHMNn1JlgUEVDN9bGV93B?key=WDdSdm4wSG90UkNwMG1FMVdSQ2p0NEFRQThPRVJ3
Is there a way to get those TrackPoints out of GarminConnect and into a file that could be rendered in, say, GoogleEarth?
