48. Internationaler Altenaulauf 2026

The Internationaler Altenaulauf features student races, a 5 km, a 10 km, and a half marathon. The shorter races offer flat routes, suitable for beginners and those aiming for a personal best. The 5 km follows an out-and-back course, and the 10 km remains flat. The half marathon presents a greater challenge, including over 200 meters of elevation gain and significant portions on forest trails; registration is mandatory for participation.
