Jesienny Ultramaraton Warmiński Warneland Łańsk is an autumn trail-and-road race in Łańsk, in the Stawiguda municipality of Poland’s Warmian-Masurian Voivodeship. Runners choose from three distances: 12.4 km, 28 km, or 53 km, suitable for those stepping up from shorter off-road races or seeking a full ultramarathon distance. The Warneland Foundation organizes the race, with entries capped by participant limits.
The routes use roads and tourist trails around Warmia, including forest asphalt roads and some public-road sections with partially managed traffic. Course marking uses ribbons and signs, with aid stations provided. The race’s identity stems from its Łańsk setting, its mix of forest roads and open-road logistics, and the three-distance format catering to different runner levels.
