Roll out of Pullach im Isartal and past Burg Schwaneck, then let the Isarauen nature reserve carry you onward. The route then threads the Südliches Gleißental and the Isarauen between Schäftlarn and Bad Tölz, both nature reserves, before Forstenrieder Park closes the loop. With 59.3 km and 574 m of climbing, most of it runs unpaved, so the gravel keeps things lively. Back to Pullach you roll.
