The running section of the race presents a proper trail running challenge. From the T2 in the village Kamno the athletes begin their running course with a rather flat section towards the town Tolmin (approximately 9 km), where the first aid station will be organized. From there on the athletes will have to conquer the 12 km long physically and especially mentally demanding ascent to the village Tolminske Ravne (750 m elevation gain), where a second, well deserved aid station will be organized. The village Tolminske Ravne is located on the 21^st km of the running section and is also marked as T3 (cut-off time). Hereafter the athletes follow the marked hiking trails past Planina Razor and towards the 1922 m high mountain Vogel, where, in case of clear weather, a breathtaking panorama of the Julian Alps on the North and gulf of Trieste on the South reveals itself. From Vogel the path leads past the saddle Globoko and back towards Planina Zadnji Vogel, where the third aid station will be organized. The athletes will then start descending from Planina Zadnji Vogel through Žagarjev Graben towards Ukanc.

The fourth aid station will be provided at the end of the descent. Just before finishing this epic race, the athletes will have to overcome the last 3.7 km of rather flat run to the finish line at Hotel Jezero.

To ensure maximum safety of all participants the trail will be marked with glow sticks. Before entering the mountainous part of the running course each athlete will go through a mandatory equipment check. A glow stick will be part of the mandatory equipment of each athlete, which will have to be carried on a visible place until the finish line. We recommend that a supporter accompanies the athletes after T3, from Tolminske Ravne to the finish line (a supporter is not mandatory during this section). In case of bad weather conditions, an alternative running route will be used.
