The Trail 100 Andorra by UTMB 2026 will take place in June 2026, consolidating the parish of Ordino as the nerve center of trail running in the Pyrenees. This prestigious international event offers four distances of 105K, 50K, 21K, and 10K, granting essential Running Stones for the UTMB World Series Finals in Chamonix. For athletes and their companions, managing transportation logistics, understanding the technical profile of the terrain, and securing reservations in the best hotels in Ordino is fundamental to ensuring a successful competitive experience.
The competition will unfold throughout the first weekend of June 2026, with official activities starting from the days leading up to it with bib collection in the center of Ordino.
The routes of UTMB Andorra stand out for their high elevation gain per kilometer ratio and for largely running above 2,000 meters of altitude, touching iconic peaks and protected natural parks such as Sorteny.

With approximately 105 km and 6,900 meters of positive elevation gain, it is an extreme challenge of pure high mountain. It crosses technical ridges, surrounds glacial lakes, and demands impeccable management of nocturnal effort and temperature changes. It awards 4 Running Stones.
A circuit of 50 km with 3,600 meters of positive elevation gain. It shares technical sections with the ultra and requires strong legs to overcome the brutal initial ascent from Ordino. It awards 2 Running Stones.
Ideal for skyrace specialists: 21 km and 1,750 meters of positive elevation gain. A leg-breaker with direct climbs and very fast descents over loose terrain and alpine grass. It awards 1 Running Stone.
The short circuit has 10 km and about 460 meters of elevation gain. It runs along the wooded trails of the lower areas of Ordino, combining fast tracks with clean paths.

Ordino stands out for preserving its traditional stone and slate architecture, offering a tranquil environment ideal for pre-race rest. Since the start and finish of all modalities are located in this municipality, booking accommodation here avoids road trips in the early hours of the morning.
The hotel inventory in Ordino is limited compared to the commercial hub of Andorra la Vella. Therefore, anticipation is key. Options are mainly divided into three logistical areas:
To guarantee the best rates and check real-time availability adapted for athletes (many establishments offer breakfast adapted to the early morning of the event), you can plan and book your stay directly from the section Accommodations in Andorra.
The event not only brings together runners but also hundreds of families who take the opportunity to enjoy Andorra's natural environment. Depending on your profile, the range of complementary activities is very wide.
While runners accumulate kilometers on the peaks, companions can explore the cultural richness of the parish. The guided visit to the Casa d'Areny-Plandolit Museum in the historic center of Ordino offers a journey into Andorra's stately past. Likewise, taking simple excursions along the Iron Route (a flat trail with sculptures that recalls the country's mining past) is a perfect alternative for children.
If you're looking to complement your trip with high-mountain hiking or plan pre-training routes, access to the Sorteny Valley Natural Park is essential. From there, ascents to Pico de la Serrera or Estany de l'Estanyó begin.

As a runner accustomed to the demanding trails of the Principality, I'll detail three critical aspects that will dictate your success or withdrawal in the Trail 100 Andorra:
The Trail 100 Andorra by UTMB 2026 represents one of the most demanding, alpine, and authentic challenges of the global trail running circuit in the heart of Ordino. Success in the competition requires not only rigorous physical training focused on steep elevation gain, but also meticulous logistical planning that prioritizes early accommodation booking and proper management of mandatory equipment.
