Roll out from Parkeerplaats Windwehetal and let the route carry you past Schloss Iggenhausen, a castle that opens the ride. Then it's nature reserve after nature reserve: Grüte, Steinbruch am Barkhauser Berg, Fleckernheide and Südkamp, each one rolling by in turn. With 629 m of climbing across 90.6 km, the legs get a workout between the green stretches. The surface stays mostly paved, and before you know it you're back at Windwehetal.
