Julian Alps Trail Run by UTMB Route 

The 120km Ultra Trail race involves 5,000 metres of ascent and is worth four UTMB running stones.

Runners begin in Kobarid, before embarking into Soča Valley. The route continues towards Tolmin, where the challenge really begins which takes runners above Podbrdo and Črna prst towards Soriška planina. 

The breathtaking views along the way, including Slovenia’s highest mountain Triglav, will spur on the runners as they make their way through the tricky course. The route continues across the ridge towards Ratitovec, before descending to Jelovica and Babji zob.  

The route heads onwards to Žirovnica, beneath the Karawanks peaks, before an ascent towards the highest peak Stol which offers stunning views of Julian Alps, before heading across the ridge to Golica and Dovška baba.  

From there athletes face a downhill trek to Mojstrana. A flat section follows next, before a further climbs aims to break the spirit of the runners. 

Climbing in Gozd Martuljek then going towards Srednji vrh, it is all downhill to the finish in Kranjska Gora. 

The 80km Ultra Sky Trail race features 3,500 metres of ascent and is worth three running stones.

The race begins in Radovljica along Sava river before climbing towards the Jelovica plateau. A trek through the forests on the way to Babji Zob follows before a trip around Lake Bled.

The biggest climb of the race awaits after Lake Blef – involving 1700 meters of elevation gain from Žirovnica towards Stol – one of the most stunning Slovenian mountain ridges. From Stol, along Golica, Hruški vrh and towards Dovška baba – almost 30km of incredible trails right at the top of the ridge.

Descending into the valley, the race follows the river Sava once more, with the finish in Kranjska Gora.

The 53km Sky Trail race, with 2,700 metres of ascent is worth two UTMB Running Stones

Beginning in the village of Žirovnica, the cultural capital of Slovenia, the route also ascends the peak of Stol before following the remainder of the 100km and 170km routes along the stunning ridge and in Kranjska Gora.
