Roll out of Luckenwalde and let the ride unfold: past the Keilberg nature reserve at Forst Zinna, then on through the Nuthe-Nieplitz nature reserve. Next comes the Oberes Pfefferfließ nature reserve before the watermill at Obermühle Gottsdorf. With most of the 64.9 km unpaved, it's a mixed-surface loop that brings you back to where you started.
