Roll out of Ruhstorf an der Rott and let the route unfold along the Rott and the Inn, with 74.9 km of paved road ahead. Castles come thick and fast: Schloß Mamling, Schloss Frauenstein, then Schloss Ering and Schloss Kleeberg. Between them you slip through the Unterer Inn nature reserve before the road turns you home. A gentle 437 m of climbing keeps it lively.
