1,700 runners, 40+ countries, and zero single-use plastics—discover how Derby backed an unforgettable trail running adventure from the Karst hills to the Adriatic sea.
At Obala Ultra Trail, it’s not just about chasing the finish line—it’s about soaking in every moment along the way. Runners wound their way through an ever-changing backdrop of golden autumn vineyards, ancient olive groves, sun-drenched Mediterranean forests, and the charming, narrow streets of coastal gems like Koper and Izola, before finally reaching the sea.
Fun fact from the world of sports: did you know that trail running on uneven terrain burns up to 10–15% more energy than running on flat asphalt? Because your body constantly adapts to changing surfaces, climbs, and descents, trail running engages significantly more core and ankle stabilizing muscles—while research also shows that exercising in green spaces lowers levels of the stress hormone cortisol noticeably faster than indoor workouts.
The excitement kicked off early at the EXPO Obala Ultra Trail, the vibrant social hub of the entire weekend. With a record number of exhibitors, athletes, and supporters swapping stories and gearing up together, the pre-race atmosphere set the stage for an unforgettable weekend.
Running with purpose: protecting what we love
Partnering with Obala Ultra Trail came naturally to us at Derby. Beyond celebrating an active, vibrant lifestyle, we share a deep commitment to protecting the trails and nature that make events like this possible.
Guided by the pledge “Together, let’s keep nature just as we found it,” the event set a powerful standard for sustainable sports:
- Saying goodbye to single-use plastics: aid stations eliminated disposable plastic cups altogether, encouraging runners to carry their own reusable flasks and refuel with crisp, fresh Slovenian tap water. Considering that each of the 1,700 runners visits an average of four aid stations along the course, that adds up to roughly 6,800 plastic cups saved in a single weekend!
- Leaving only footprints: with reusable course markings, trail maintenance in partnership with local communities, and a strict zero-litter policy, every participant helped ensure the landscape remained just as pristine after the race as it was before the starting gun.
Here’s to the next adventure
To all the runners who conquered the hills, pushed through the toughest miles, and crossed the finish line with a smile—you are a true inspiration. A huge thank-you also goes to the organizers and tireless volunteers, whose dedication continues to put Slovenia on the global trail running map.
