UltraKotlina 2026

UltraKotlina is a trail running series held in Szklarska Poręba, a mountain town in Poland’s Lower Silesia region. It takes place in early October in the Sudetes, offering five race distances: 34 km, 56 km, 79 km, 140 km, and 181 km. The 140 km race can be completed solo or as a relay, transforming the event into a full ultra weekend. The courses traverse mountain, forest, and natural terrain in the Karkonosze area. Runners can anticipate significant climbs, forested paths, and Sudetes weather conditions, distinct from road racing. UltraKotlina is included in the UTMB Index, contributing to runners' performance records within the broader UTMB system.
