>>1772534btw, in case anyone is interested: the screenshot is from
bikemap.net, it's the approximate route i used, i downloaded it as a gpx (for each day at a time) and put it on a garmin device which i used for navigation.
there are some caveats:
one time it lead me to a ferry that was not in operation and i had to ride an extra 10km to the nearest bridge, 2 times it lead me over stairs, a few times over forest roads that were barely ridable
that said, this was the first time i used a navigation device and it was super comfy, otherwise i'd been totally lost
