Roll out of Luckau and into the Spreewald, then on through the Innerer Oberspreewald and the Tagebau Schlabendorf-Süd, three nature reserves in a row. Past Gutshaus Mallenchen manor and Schloß Beesdau castle, the route swings through Borcheltsbusch und Brandkieten before heading home. With 72.7 km of paved surface and just 176 m of climbing, it's an easy-going loop.
