Roll out from Parkeerplaats Bergholz and let the ride unfold: past Schloß Ostrau, on to the Burgstetten viewpoint, then along the Saale and the Mühlgraben canal. The Porphyrlandschaft bei Gimritz nature reserve leads you toward Burg Wettin and its Unterburg, before the Bergholz nature reserve brings you home. It's 80.4 km, all paved, with 409 m of climbing.
