The event in a few words

The dawn of a new year is often synonymous with fondue 🫕, a blanket and binge-watching in full cocooning mode 📺. For La Corsa della Bora, it means lacing up your sneakers and getting ready for a little hair rebellion 💇‍♂️.

In early January, this trail will take you around Trieste, between Slovenia 🇸🇮 and the Adriatic Sea 🌊 on the Italian side. Yep, you'll follow the Italian-Slovenian border with nothing but the power of your legs🦵. No need to worry about the weather: it will be just cool enough for your legs to work and for every stride to be felt ❄️. The start will be from the seaside resort of Sistiana, at PortoPiccolo 🌴 (except for the " S1 Trieste Ultra" of 61 km and the "S1 Bora Ultra" which will start from Trieste 📍)—but no time to sunbathe 👙! Very quickly, you’ll string together trails, typical villages and little surprises along the route, enough to keep your eyes and calves busy 😏. You’ll run, you’ll laugh, you’ll enjoy it, and you’ll start the year somewhere other than the couch 🛋️. After a few kilometers, you’ll realize that winter can actually be pretty nice when you spend it outside 😎.

The menu? It’s à la carte 🍽️. As a starter, the "S1 Borin" (4 km) and the "Family Hike & Trail" (14 km) will be perfect for warming up, strolling with the family or saying “I did the S1” without sweating too much 😌. You can even do them in hiking mode 🥾 and bring your little four-legged buddy 🐾. For the main course, we’re serving up the "Half Trail" (23 km) and the "Borderless Trail" (36 km) 🏃‍♂️: long enough for a real nature 🌲 getaway, short enough to be back in time for aperitivo 🍺. And for the big appetites, there’s the all-you-can-eat buffet: "TransKarst Ultra" (55 km), "Trieste Ultra" (84 km) and the sacred monster, the "Bora Ultra" (116 km) 🥵. At that point, it’s no longer sport—it’s a spiritual quest 🧘, but certified UTMB World Tour. As for the course, hang on tight: you’ll cross the Karst plateau, run along the sea, climb ridges 🔭 and venture onto the legendary Sentiero Rilke 🏞️, a true suspended balcony. We hope you’re not afraid of heights 🥴. In short, between the sweat 💦, the rocks 🪨, the wind 💨 and the “woooow look at that!” 🤩, you won’t have time to get bored. And watch out—the Bora can turn your trail into an impromptu paragliding session... 🪂 Try not to take off! 🛫 At the finish, Portopiccolo will roll out the red carpet 🎉. You’ll soak up the big harbor atmosphere with volunteers who make you feel like a star 🌟. It’s not quite the Cannes Film Festival, but almost! 😅

If you want to keep the party going🥳, we’ve got a few recommendations for you! Because the Friuli Venezia Giulia region isn’t just about running and heading straight home afterward ❌. It’s a place that blends Austro-Hungarian elegance with Italian dolce far niente 😍. You can sip your spritz facing the gulf in a classy mood 🍹 in Trieste, admire the Miramare Castle perched over the sea 🏰, or wander through the downtown alleys, stopping in one of its typical cafés ☕. And when hunger catches up with you, get ready for a festival of flavors: San Daniele prosciutto that melts on your tongue 🥓, Friuli cheeses that will make you forget your Babybel 🧀, and white wines from the hills that go down easily on their own with a risotto 🍚. If you want to extend the adventure, know that Ljubljana 🇸🇮 is only a 1.5-hour drive away 🚗. So we’ll let you choose between Italy and Slovenia for what comes next 😜.

You come for the calves, you stay for the views, you leave with a head full of memories 😍.

4 reasons to join this race

A unique playground between two countries 🌍
Running on the Karst plateau is already an adventure in itself. The route follows the Slovenian border and will offer you a pretty crazy variety of landscapes: rocky coastline, wooded trails, wide-open views over the gulf, and snowy mountains in the background. You’ll go from technical high-altitude sections to more runnable stretches where your legs can really open up 💨.
Prestige ultra 🏅
The long races of the S1 ("TransKarst", "Trieste" and "Bora Ultra") are part of the UTMB World Series circuit. In other words, you’ll enjoy an insane trail between land and sea while racking up points for the biggest international challenges. Not bad for starting the year in adventure mode and as a future UTMB finisher, right? 😎
The full cultural experience 🇮🇹
Trieste is the perfect blend of wild nature and the comfort of a big city. After the effort, you can explore every corner, taste local specialties and soak up the atmosphere of this border region. Trail running, culture, gastronomy, a change of scenery—it's the perfect combo for a memorable weekend! 🔥
The perfect Mediterranean winter for running 🏃
Weather-nerd mode activated! Trieste offers a mild winter climate with sea views and snowy mountains in the background. It’s the ideal destination for a winter break without freezing your calves off. Plus, there’s no performance pressure: you can run for fun in unpredictable weather conditions that are never extreme! ☀️

A few more words

You will start the 116 km ultra along the shores of the Adriatic 🌊, with a section behind Trieste. Before long, you’ll leave the seafront to climb onto the Karst plateau, where wild, open limestone landscapes will be waiting for you 🌿. The route will then take you to the Slovenian border 🇸🇮, heading toward Bagnoli della Rosandra, with long, runnable yet demanding sections. Around km 35, you’ll string together climbs and descents before reaching the border area again at km 50.

After that, you’ll gradually make your way back toward Italy, across the Karst, until you catch sight in the distance of the sea and the cliffs of Duino and Sistiana 🌅. The final kilometers will have you running along the coast before dropping down to the finish in Sistiana, after more than 116 km and 3,900 m of elevation gain 🔥.
