The RAWRUN Mulhouse Trail is a 21 km (430 m D+) urban and nature trail run set in the heart of the Mulhouse metropolitan area. The course starts and finishes at La Fabrique, 98 Rue de Bâle, and crosses five municipalities: Mulhouse, Riedisheim, Rixheim, Zimmersheim, and Bruebach. The route combines urban segments, forest trails, stairs, parks, technical climbs, and natural sections, including the Tannenwald forest. The course is fully marked, secured, and supervised by volunteers and medical teams. Organized by the RAWRUN association, the event promotes a raw, human, and inclusive approach to trail running, with a strong focus on runner experience and environmental responsibility.
