The new route first follows the Soča River and climbs below Mt. Krn. Crossing the Zatolmin mountains, the route passes the world-famous memorial church on Javorca, before descending back into the valley of the Tolminka river. The route then follows the Tolminka river all the way to the starting point at the confluence of Soča and Tolminka.

Between the festival venue in Tolmin and the village of Kamno in the valley, the route runs almost entirely on gravel paths and cart tracks along the Soča River. In the village of Gabrje, the route turns away from the river and bites into the first steep, but short ascent. Reaching the village of Volarje, the route descents back down towards the river.

Most of the ascent between the villages of Kamno and Krn runs on a well-maintained asphalt road. After Krn, the route turns into a forest road in the direction of Mt. Pretovč. A short section of this path is very narrow and competitors need to dismount their bikes here.

Near the hunting lodge on Mt. Pretovč, the trail joins the connecting route between the Zatolmin mountains. The latter runs mostly downhill on a gravel path from Mt. Medrje across Mt. Laška seč, Črča, Zagrmuč and Javorca, all the way to Mt. Polog. At the Javorca Memorial Church, the route runs on a scenic paved road. In the valley, it reaches a well-maintained forest road, which is mostly gravel, but also has a few asphalt sections.

At the church of St. Peter, which is located at the entrance to the Triglav National Park, the route turns left towards Tolmin and then to the Tolminka River. The last part of the route follows the river all the way to the marathon starting point at the confluence of Soča and Tolminka. Due to organizational reasons, the initial and the final section of the route might still be changed.

The eighth edition of the Soča Outdoor Festival since 2014 brings the discipline of MTB XC Marathon back to Tolmin with a classic marathon distance and a brand-new route.

The biking competition takes place on the last day of the festival, on July 4th 2021. The start of the competition is scheduled at 9:00 at the main festival venue. Timing ends at 14:00.
