The ISMF World Cup circuit makes its traditional stop in the Boí Taüll Pyrenees, hosting the 4th stage of the season in one of the most iconic venues on the World Cup calendar. Renowned for its high-altitude terrain and demanding courses, Boí Taüll once again promises a spectacular showcase of ski mountaineering — with an added twist this year: Sprint and Mixed Relay races.
Set in the heart of the Catalan Pyrenees, Boí Taüll offers races that consistently take place above 2,000 meters, where altitude, technical terrain, and winter conditions push athletes to deliver their very best.
On 31 January – 1 February, the world’s top ski mountaineers will face a double challenge, highlighted by the second Mixed Relay of the season. With the Milano Cortina Olympic Games on the horizon, this race will be a key test for Olympic-bound teams, adding an extra layer of intensity and strategy to the competition.

Thanks to the outstanding work of the Local Organizing Committee and the Boí Taüll Ski Resort, athletes and media can once again rely on a perfectly prepared venue and world-class event organization — reinforcing Boí Taüll’s reputation as a benchmark destination for elite ski mountaineering events.
SPRINT RACE
The Sprint course features a 68-metre elevation gain, delivering a fast and highly technical challenge.
The course begins with a medium-steep opening section, rated two diamonds, followed by a more demanding three-diamond uphill. A short flat section leads into the boot-pack section, featuring the characteristic stairs, before athletes transition into another flat stretch that brings them to the transition zone.
Athletes then enter a fast downhill, followed by a long and flat traverse. The course concludes with a 180-degree turn leading into an uphill finish, where athletes arrive in skating mode to sprint across the finish line.
MIXED RELAY RACE
The Mixed Relay course offers a compact yet intense test of speed, power, and
technical skill, featuring two uphill sections of 68 metres and 83 metres respectively.
The course begins with an already medium-steep opening section, rated two diamonds, followed by a second, more demanding uphill section rated three diamonds. A short flat section then allows athletes to accelerate before entering a moderate uphill, leading into another flat stretch.
Athletes then face the first downhill, which brings them onto a large platform and into a technical zig-zag uphill that continues up to the boot-pack section. After a short straight line following the boot-pack, athletes enter the transition area.
The final part of the course features a downhill with a traversing section before athletes tackle a steep final slope, arriving either at the handover zone or the final transition. With just 15 metres between the last transition and the finish line, the course is designed to deliver an exciting and fast-paced finale, where every second will count.
