In the festival program "Challenge Days 2025" viewers will be able to immerse themselves in one of the most extreme mountain biking adventures in the Balkans – Hellenic Mountain Race 2025.
In May this year, Bulgarian cyclists Tsvetan Ivanov and Dimitar Mihaylov embarked on a tandem ultra challenge in the Greek mountains – 900 km and over 32,000 m of elevation gain, completed entirely on their own and without outside assistance. Each participant carries all their own equipment and relies solely on their own endurance, preparation, and logistical decisions.


Many of you know how much I love challenges, or rather, how much I love the unknown in them. I love that ultra-little, ultra-ultra... thing that makes all the difference, actually." says Tsvetan Ivanov. And about the competition itself, he adds: "The Hellenic Mountain Race is more than human limits can comprehend. It's not just mountain biking, it's huge logistics, preparation, and planning."


The presentation and film dedicated to their participation will reveal what it's like to go beyond your limitswhere does the secret of survival lie, and what inspiration does the courage to embark on the journey bring?
