GOOGLE MAPS

[emptysea]

I copied your map to my account so I could edit it. To change the route, first click on the route line. It will change to a lighter shade of blue with a white highlight. Then click on it again and hold the mouse button to drag it to a new road.

Edit: actually, this is very odd. The entire route moved as a unit, keeping the same geometry. On maps I've created, after I've clicked the route to highlight it, I then get a white circle as I hover over the route. I can click and hold to drag this white circle to a new position.

I suspect that your editing issue is because I created the map in Google Maps then converted it to GPX before importing into MyMaps. I did it this way because it's MUCH easier to search for a location (in this case Shell gas stations along my route) in the regular version of Google Maps than it is in MyMaps. If I'm right, I think I will need to have my map 100% correct before exporting it to MyMaps, but maybe there's a work-around.
