Marathon des 10 Étangs

The Marathon des 10 Étangs is a trail-running event in Hahnenklee, Lower Saxony. Runners can choose from a 5 km trail to the full marathon, accommodating both short-distance runners and those seeking a longer run. This is not a road race; water, forest, and narrow paths are the main features. The routes run through wooded sections and along ponds, with each distance laid out as a single loop. Runners head out, settle into a rhythm, and return without repeating sections. The field is mainly made up of people who want an outdoor test rather than a city-race atmosphere: runners looking for trails underfoot, quiet surroundings, and a course that keeps them close to the lakes and forest around Hahnenklee.
