Roll out of Berghausen and let the ride unfold: past the Erlachsee nature reserve, then on to Schloss Gottesaue and Schloss Karlsruhe, with a pause at the Schlossturm viewpoint. The route keeps rolling through the Saalbachniederung, past Schloss Bruchsal, and into the Steppenheide am Bittberg and Schreibersklamm nature reserves before the loop returns to Berghausen. With 78.1 km and 729 m of climbing, it's a day of castles, reserves and mixed terrain.
