Wald-Läufer
I totaly forgot...
For navigation I use a Garmin Edge.
I just checked if I can get the gpx track.
Maybe it's not really helpful, because I moved first to the wrong side of the river and then back (after a few meters), but maybe you can use it together with the other track...
I pushed it to osm. I hope you can find it!
I set the name of the node: 3122795
Thanks for fixing that! :o)
