SOČA

Soča 25km

27th June 2026 at 7:30 - Tolmin, Slovenia

From past experience, we recommend this run to those who have already tackled a flat marathon (42 km). The route starts with two warm-up climbs – first to the church of St. Mark above Žabče and then up from Tolmin Gorge. But don’t leave all your breath on these scenic spots, because next up is the ascent to Tolmin Castle. And just when you think you’ve seen it all, the trail takes you even higher – to the Open-Air Museum on Mengore and the panoramic viewpoint at Bučenica. There you have it, a full Tolmin tour from three sides! Now, time to head back to the festival grounds. For the perfect finishing touch – hop – over the Tolminka River and… collapse onto the pebble beach or under the shade of ancient trees. You did it!

AID STATIONS

We are trying to reduce negative effects of the festival on the environment, therefore cups for one-time use will not be available at the water stations and fit zones. We ask runners to bring their own cup, bottle or a camel bag to use it at water stations and fit zones for water and energy drinks. Runners will be able to purchase reusable cups at the registration point.
