Bottroper Herbstwaldlauf / Ultramarathon

The RWW-Herbstwaldlauf is the Bottroper Herbstwaldlauf, a German running event offering both 10 km and 50 km races. Its name translates to autumn forest run, placing the event within the tradition of German club-style road and trail races that focus on distinct distances rather than a single main marathon. The key feature is the choice of distances: participants can select either a standard 10 km or a 50 km ultra within the same event. While specific route details, field size, and traditions are not readily available, the race is listed as the 53rd in its series, indicating it is a long-established event, not a new or infrequent one.
