Roll out of Winterbach and let the ride unfold past the Sommerrain and Schmalenberg nature reserves before the Lorcher Baggerseen lakes appear. Onward through Morgensand und Seelachen, then a castle at Burgschloss and the Hahn'sche Mühle watermill. With 74.6 km and 1055 m of climbing, it's a loop that keeps giving, and almost all of it is paved. Back to Winterbach where it began.
