adidas Terrex 15 km trail starts at the main festival venue and continues towards Kamp Gabrje where it turns and steeply ascends towards the Tolmin Castle. From the top of the castle hill the trail leads to the village Zatolmin and to the Tolmin Gorges from where it descends to the confluence of  Zadlaščica and Tolminka rivers just to make another uphill leg to the village Žabče.  Trail continues to the underpass of the main road Tolmin – Most na Soči and finishes  at the confluence of  Soča and Tolminka rivers. The last obstacle to overcome is Tolminka river which runners have to cross right before the finish line.
