Roll out of Mitterndorf an der Fischa and let the ride unfold: first through the Obere Au forest, then past Schloss Brodersdorf and along the Leitha river. Further on come Schloss Ebenfurth, the Schloßgraben and the castle ruin at Pottendorf, before Schloss Schöngrabern and the Fischa river guide you home. It's 74.4 km, all paved, with 437 m of climbing along the way.
