I went for a walk. i started the track and ended the track.
At home i logged onto Explore at share.garmin.com. I can see my track in the left column, called "Track Summary" and click on that and see the track with all its points on the map. I don't see how to delete it or edit it - no garbage can or editing pencil.
I can click on the track on the map and see the info, and click to see more, but no can or pencil.
You can see that this has worked before - i've edited previous track names.
Also, why is my max speed 5.75 - I'm pretty sure i can't snowshoe that fast. (an old complaint - for another time)
