Trieste: where the trail meets the seaThe Gulf of Trieste is the ideal destination for winter trail running. Mild climate on the coast, snow-capped mountains in the background, trails that in just a few kilometres go from the seashore to the Karst paths.
From mountain to seaRoutes ranging from the rocky coastline to the Karst forests. You go from altitude to shore in just a few kilometres: technical terrain, fast descents and views that change with every turn.
Karst, two countriesThe trails cross the Italian and Slovenian Karst: Bora-beaten moorland, fragrant pine forests, hidden dolines and paths from the Great War. A border territory without equivalent.
Mitteleuropa by the seaTrieste is a capital city with all the amenities, but with the soul of a border city: historic cafes, Habsburg architecture, bookshops and theatres. After the race, the city is part of the experience.
Zero km at the aid stationsAt the aid stations you will find typical Karst products: cheese, salami, Teran wine, olive oil. Strictly zero kilometre, strictly handmade.
1The right winter for runningLa Corsa della Bora is perfect for those who want a break from the racing season without stopping - or for those looking for technical terrain at low altitudes where they can push themselves to the limit. Wide times, distances for all levels, no ranking pressure: enjoying the scenery is already the result.
2Challenge or discovery: you chooseSeven distances, from 4 km to the 116 km ultra. For those who want to push themselves, there are technical sections and descents where the legs spin fast. For those who want to explore, the routes pass through villages, cliffs, trenches and woods that in themselves are worth the journey. You don't have to choose beforehand: the Karst terrain decides for you.
The Transkarst Ultra is for trained trail runners who are looking for something more than a long race: an experience with a strong identity, where perception changes and the idea of crossing becomes the protagonis

The Borderless Trail is the right choice if you want a characterful race, with that border flavour that makes the experience different from the classic “loop” races. It is suitable for those who like variety and trails that change pace and atmosphere, without being an extreme ultra, but remaining a serious and memorable race. It is a race that leaves you with the impression that you have really moved within a place, not just within a distance.
The S1 Half Trail is the most balanced race for those who already run trails and are looking for a complete experience: varied, engaging, with the right mix of smoothness and fatigue. It is suitable for those who want a real but manageable challenge, without extremes, where rhythm, continuity and a bit of attention in the rougher sections count. It is the perfect distance if you want to feel the soul of the Bora and finish with the feeling of having done trail running ’properly“.
The S1 Family Hike & Trail is designed for those who want to experience La Corsa della Bora in a simple and enjoyable way: plenty of beauty and atmosphere, without having to chase performance or manage challenging stretches. It is the right choice if you want a “full” but accessible day, also suitable for first-time runners or for those who prefer to enjoy the terrain calmly, taking home above all views, wind and that feeling of travel that comes immediately
