This route involves ascending Germany's highest mountain "Zugspitze", followed by traversing "Jubiläumsgrat" (https://en.wikipedia.org/wiki/Jubil%C3%A4umsgrat) towards "Alpspitze" and then descending back to the valley (Hammersbach). 

Route has to start and end at "Hammbersbach Wanderparkplatz P2". Routes up to "Zugspitze" and down from "Alpspitze" may differ. Route of "Jubiläumsgrat" must be accurate.
