UltraŁemkowyna 150 km is a point-to-point mountain trail race held on October 17, 2026 in southern Poland, starting at 01:00 in Krynica-Zdrój and finishing in Komańcza — a full traverse of the Beskid Niski range along the historic Main Beskid Trail. The course gains 5,860m and loses 5,970m (+39.1 m/km) across a symmetrical ridge profile: 38.8% uphill, 22.7% flat, 38.5% downhill.
The race's defining feature is not its gradient but its conditions — the Beskid Niski is notorious for turning October trails into seas of mud, with multiple editions featuring knee-deep forest paths. The most technically demanding moment is Descent 1 at km 26.2: 304m over 1.9 km at −16.4% average and −33.3% maximum — a steep muddy plunge in the first quarter. The biggest climb (376m, 7.4 km) arrives at km 118.5, the final quarter, on legs that have covered the entire Beskid Niski. Entry costs €0.88/km (549 PLN current tier). Kraków (KRK) or Rzeszów (RZE) are 173 minutes away by road.
Running since 2014, the race drew 212 finishers in 2025 against a 35-hour time limit. It suits experienced mountain ultra runners with strong technical descent ability and high tolerance for variable autumn Carpathian conditions.
