Is anyone ever truly ready for a
20 km trail race?
Don’t let the distance fool you – this is no road half marathon. The course is dynamic and fast, but still packs around 500 metres of climbing. And if the weather behaves the way it should at the start of summer, you probably won’t be feeling cold. So here’s the deal: you bring strong legs, and we’ll make sure there are plenty of drinks waiting for you at the aid stations.
The extraordinary nature of the Soča Valley will provide plenty of inspiration along the way. From the ruins of Tolmin Castle on top of Kozlov rob, you’ll look out over Tolmin and the surrounding landscape. In the Tolmin Gorges, you’ll see what centuries of water can do as the small Tolminka River carves its way through rock, creating dramatic limestone walls. And just like the landscape, running is about more than one race day. It’s about all the kilometres you’ve put in over the months and years before.
Once your body is ready, all that
effort turns into pure joy.
Long-distance running is a long-term investment. The moment you step into the Tolminka Stream just before the finish after 20 kilometres is one you’ll carry with you forever.
TRAIL
Runners will receive the latest GPX files together with the race guide shortly before the event.
