Roll out of Heiligenhafen and along the Oldenburger Graben, a river that sets the tone early. Next up: Schloss Weißenhaus, a manor, before the Weißenhäuser Brök nature reserve and the Wesseker See nature reserve unfold in turn. All 89.4 km are paved, with 414 m of climbing to keep the legs honest. Then it's back to Heiligenhafen, where the ride began.
