Roll out from Parkeerplaats Lindenberger Wald and the ride unfolds past the Gillenbusch nature reserve, then the Erft between Bergheim and Bedburg. Schloss Paffendorf, Burg Zieverich, Burg Bergerhausen and Kommandeursburg follow, castle after castle. Onward through the Bürgewald Steinheide and Lindenberger Wald nature reserves, with 91.6 km, 284 m of climbing and a touch of unpaved along the way, before you're back at the start.
