1. Ultramarathon am Dreiländereck (NED/GER/BEL)

The Ultramarathon Triple is an epic three-day endurance challenge that spans across the borders of three countries: Netherlands, Belgium, and Germany. This unique race offers runners the opportunity to tackle diverse terrains while experiencing the cultural richness of each nation.
Day 1 - Vaals (Netherlands)
Starting in the picturesque town of Vaals, located at the tri-border area where the Netherlands meets Belgium and Germany, participants begin their journey on September 25th. The route for this day is a rugged 15.3-kilometer loop that ascends to an elevation gain of approximately 290 meters (according to Komoot). Runners will navigate through unmarked trails, making navigation skills essential as they cover the terrain three times in total.
The race starts and finishes at Parking Lot P2 near the Dreiländereck. Participants are advised to bring their own supplies for hydration and nutrition since there is no official support along the course. The parking area serves as a checkpoint every lap, so runners should plan accordingly by carrying water or other necessary fluids during the run.
Day 2 - Eupen (Belgium)
On September 26th, participants continue their journey in Belgium at Eupen. While details about this leg of the race are not provided here, it is part of a larger itinerary that builds on the previous day's efforts, offering another challenging course through Belgian landscapes.
Day 3 - Nideggen-Schmidt (Germany)
The final stretch takes place in Germany near Nideggen-Schmidt on September 27th. This concluding leg promises to be as demanding and rewarding as its predecessors, wrapping up the three-day adventure with a sense of accomplishment for all who complete it.
Each day's race is an individual start event, allowing participants flexibility in their pacing strategy across varying terrain and weather conditions. The organizers, Ute Karklis from Steinhagen and Uwe Laig from Lengerich, emphasize the importance of self-sufficiency throughout the entire Ultramarathon Triple experience.
Registration for this endurance challenge remains open until 6 PM on the day before each event's start date or earlier if participant limits are reached. Interested runners can sign up via race result platforms, and last-minute registrations may be possible with organizer approval.
This multi-day ultramarathon is listed under DUV (Deutsche Ultramarathon Vereinigung), ensuring a high standard of organization and recognition within the endurance running community.
