Route: Bodensee Umrundung (Germany, Switzerland, Austria)

Die Bodensee Umrundung umläuft den gesamten Bodensee inklusive Untersee und Überlinger See.

While the Bodensee-Radweg is one of the most popular bicycle routes in Europe, this FKT is a "free course" finding the shortest/fastest route to circumnavigate the lake on foot.  It is often, but not always, on the bike path.  Approx. 200km.
