UltraKotlina 2026

UltraKotlina 2026 is a multi-distance mountain running festival held across the Sudetes with a central festival base in Szklarska Poręba. The weekend (9–11 October 2026) brings together seven branded distances — UK140, UK100, UK80, UK50, UK30, UK15 and a team relay (Sztafeta) — that traverse four mountain ranges (Karkonosze, Rudawy Janowickie, Góry Kaczawskie and Góry Izerskie) and all finish in Szklarska Poręba. The programme combines long-distance solo ultras, shorter mountain runs and a relay option, with mobile race offices, packet pickup at the event base and on-course support to suit each distance.

The event is organised by Fundacja Przejście Kotliny under the UltraKotlina brand and offers substantial elevation and technical mountain terrain across its distances, with purpose-built logistical support such as bus transfers to start locations and depot/bag-drop services at the base. Several races (for example UK100 and the Sztafeta) publish GPX/routes and a detailed map on the official site, and the organisers emphasise generous time limits to allow participants to enjoy the courses. Registration for the 2026 distances is processed via the official registration partner and the site publishes the athlete base (packet pickup, mobile offices and finish festival) centrally in Szklarska Poręba.
