Roll out of Lilienthal and let the ride unfold: first past the Butendieker Gehölz nature reserve, then on through the Borgfelder Wümmewiesen. The Fischerhuder Wümmeniederung and Untere Wümme nature reserves follow before the loop brings you home. Along the way, 61.1 km roll by, with 37% of it unpaved and just 128 m of climbing.
