The Lauwersmeer Najaarstocht begins and ends at the Staatsbosbeheer activity centre entrance to Lauwersmeer National Park, close to Lauwersoog in the northern Netherlands. This autumn event is for walkers and runners, offering distances of 5 km, 10 km, 15 km, and a half marathon, allowing participants to select an easy walk or a more challenging trail run.
The routes traverse the Lauwersmeer area along unpaved paths, featuring open nature and a peaceful national park atmosphere instead of a city-road race environment. Stichting 40Mijl organizes the event, and practical information, including route details, parking instructions, and the precise schedule, will be provided to participants shortly before the event.
