The Julian Alps Trail Run by UTMB is Slovenia's largest trail running event and the only Slovenian race in the UTMB World Series. With six distances from 10 km to 120 km, runners explore Triglav National Park's alpine meadows, dense forests, and panoramic ridgelines, with the iconic Lake Bled as a backdrop.
Based in the charming alpine resort of Kranjska Gora, the Julian Alps Trail Run by UTMB invites over 5,000 runners from more than 80 countries to discover the magnificent beauty of Slovenia's only national park. Triglav National Park is a pristine sanctuary of soaring peaks, crystal clear rivers, and flower filled meadows that embody the very essence of European mountain running.
The flagship 120K course covers 120 kilometers with nearly 5,900 meters of elevation gain, threading through iconic locations including the shores of Lake Bled, the historic town of Radovljica, and high alpine passes with views stretching to the Adriatic. The 80K, 50K, and 25K distances each deliver their own blend of technical challenge and scenic reward, while the 15K and 10K formats offer accessible entry points into this extraordinary landscape.
What elevates this event beyond its stunning terrain is the warmth of Slovenian hospitality and the intimate scale of the Julian Alps. Here, world class trail running coexists with village charm, local gastronomy, and a deep reverence for nature that permeates every kilometer of every course.
