About the Event

Immerse yourself in the rugged beauty and rich history of Slovakia with the BBU races. These events take place across the undulating hills of Kysucká vrchovina, where runners are greeted by panoramic views of Malá Fatra's peaks and the dramatic landscapes of Strážovské vrchy. The journey begins at Budatín Castle, a historic landmark that sets the stage for an unforgettable adventure.
The BBU100+ race offers an epic challenge through varied terrain, while the relay version allows teams to share in the scenic delights. For those seeking a more compact yet equally thrilling experience, the new BBU40 race starts at Turie and quickly leads runners along the Súľov Rocks ridgeline.
The centerpiece of this event is its diverse route that winds through four castles, each adding a touch of historical grandeur to the journey. As you traverse runnable meadows and enchanting forest paths, prepare for technical sections over rocky terrain and steep ascents and descents. A refreshing river crossing adds an element of adventure before concluding at Budatín Castle.
Whether tackling the full BBU100+ or enjoying a shorter distance like the new BBU40 race, participants will experience Slovakia's natural beauty combined with its rich historical backdrop, making this trail-running event truly unique and exhilarating.
