About This Race
The Julian Alps Trail Run by UTMB 80K courses through Slovenia's Triglav National Park, connecting remote mountain valleys and high alpine zones in the eastern Julian Alps. Starting and finishing in Kranjska Gora, a mountain resort town near the Austrian and Italian borders, the route explores terrain that ranges from forested river valleys to exposed ridgelines where weather systems move in quickly from the surrounding peaks. This is UTMB's flagship distance at the Julian Alps venue, drawing experienced ultra runners to a course that requires sustained technical footing and careful energy management. The race typically runs in mid-summer, when snowmelt has cleared the higher passages but alpine conditions remain unpredictable. Runners encounter stream crossings, rocky descents, and extended sections above treeline where navigation skills and weather awareness become essential. The 80K serves as a qualifier for UTMB Mont-Blanc and attracts a field familiar with European mountain racing. Aid station spacing reflects the remote nature of the route, with several sections requiring self-sufficiency between support points. The finish in Kranjska Gora places runners back in the heart of a town that has hosted international mountain sport for generations.
The course moves north from Kranjska Gora into the Martuljek mountain group before turning south through the Vrata Valley beneath the north face of Triglav, Slovenia's highest peak. Technical singletrack dominates the route, with extended sections on rocky alpine paths that demand consistent attention to footing. Forest trails provide brief respite between higher elevation passages, but the overall profile maintains a demanding character throughout.
Runners navigate terrain shaped by glacial history and limestone geology, passing mountain huts and shepherd stations that have served alpine travelers for centuries. The route's remoteness means limited bailout options once committed to certain sections, making proper pacing and gear selection critical from the start.
