Roll out from Parkeerplaats Nachtweid von Dauernheim and straight into the Nachtweid nature reserve. Then it's on along the Nidda river to the Mähried bei Staden nature reserve, before the Nidder river leads you to Schloß Assenheim. Of the 62.3 km, just over half runs unpaved, and 593 m of climbing keeps things lively. Back to where you started.
