The longest race of the festival. It goes through the Tolmin Gorges, past Tolmin Castle on Kozlov Rob and the Grofova voda spring, then along the Soča River. It climbs Mengore hill, passes the lake at Most na Soči and the Senica viewpoint, and finishes with a wade through the Tolminka River at the confluence. There are 8 aid stations and intermediate cutoffs at Gabrje, Most na Soči and Senica.
