This 54.0 km loop rolls out from Parkeerplaats Helstorfer Altwasser and soon meets the Leine, the river that shapes this landscape. From there it winds on to the Helstorfer Altwasser nature reserve before turning back toward the start. With 62% of the route unpaved, the mix of surfaces keeps things varied under your wheels, and 82 m of elevation gain means the pedaling stays friendly throughout.
