VI Zimowy Ultramarton Kurpiowski

The 6th Kurpie Winter Ultramarathon is a winter running event held in the scenic forests of the Ostrołęka Forest District, near Łęg Starościński and the Lelis Forest District. Participants can choose from four distances: 56 km, 28 km, 10 km, and 10 km Nordic Walking. The routes follow forest tracks with a few climbs, and the start and finish are at the Running Shelter. The event is well organized, with aid stations along the routes and a limited number of participants, creating an intimate atmosphere.

The participant limit is 150 paid entrants. The 56 km and 28 km routes are forest loops, with aid stations operating during specified hours. Starts are staggered: 56 km at 7:00, 28 km at 9:00, 10 km Nordic Walking at 10:00, and the 10 km run at 11:00. In the 2026 edition, aid stations along the route served hot tea and meals, and there were bonfires. The limit was 150 paid participants. Price and route information comes from the 2026 edition.
