100 Meilen Berlin – Mauerweglauf - Reiner Mehlhorn 2026

100 Meilen Berlin – Mauerweglauf is a 100-mile ultramarathon in Berlin tracing the former Berlin Wall's path. It is a long, demanding race centered on a single concept: crossing the old Wall route on foot, with the city’s history directly beneath the course. The race attracts German and international ultrarunners, some planning for it years ahead because of the distance and timing requiring serious commitment. Reiner Mehlhorn is the organizer, and the challenge is framed as mental as much as physical: the task's scale depends heavily on the runner's mindset, and nerves can heighten as the start approaches.
