Roll out from Parkeerplaats Espenloch-Hintere Halde and the Rammert forest closes in before the route drops through Katzenbach-Dünnbachtal nature reserve. The Neckar river leads you on toward the Heuberger Warte viewpoint, then the Starzel river keeps you company to Schloss Hirrlingen castle. Of the 54.7 km, most runs unpaved, and 733 m of climbing keeps it lively. Back at the start, you'll know you've ridden.
