Bjelasica Trail

Bjelasica Trail is the biggest trail running event on the Bjelasica massif, raced each August from Kolašin across the mountain and through Biogradska gora National Park — home to one of Europe's last primeval forests. Now an established fixture of the northern racing calendar, it fills Kolašin with runners for a full weekend each summer.

Kolašin is the north's most polished mountain base — a small town of hotels and café terraces in the Tara's upper valley, with Bjelasica's rounded green ridges rising directly behind it. Where Durmitor is rock and drama, Bjelasica is grass, forest and water, and the running reflects it: fast, flowing and endlessly scenic.

The flagship Red course is a proper mountain ultra: 60 kilometres across Bjelasica's ridges and pastures. Below it sit the 40-kilometre Green course, plus 23 and 12-kilometre races that open the weekend to strong recreational runners, and a kids' race that gets the youngest onto the trails. The main distances all carry ITRA points, drawing runners chasing qualifying credentials as well as scenery.

And the scenery earns its billing. Courses pass Biogradsko jezero, the forest-ringed glacial lake at the heart of the national park, and the katun Vranjak, a traditional shepherd settlement on the high pastures — a route that compresses Bjelasica's best into a single race day.

Race weekend fills the town centre with bibs, pasta and nerves, and the finish-line atmosphere lasts well into the evening. Supporters have an easy time of it — the start and finish sit on the central square, and the national park's lakeside paths make a gentle day out while the runners work above.

The 2026 event runs over the 8–9 August weekend, with all courses starting from Trg boraca in the centre of Kolašin. Entry fees apply per distance, and full course details and registration are at bjelasicatrail.me.
