Roll out from Parkeerplaats Digelfeld and let the ride unfold: first past Burg Rechtenstein, then on to Burgruine Bussen, two castles in the opening stretch. The middle of the route swings through Flusslandschaft Donauwiesen and Steinberg-Dürrenfeld, both nature reserves, before Halmberg and Warmberg keep the green coming. With 1190 m of climbing spread over 91.3 km, the legs will know they've been out. It's 98% paved and 2% unpaved, and the loop brings you back to where you started.
