Official distances and routes: Technical analysis

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.

Ultra Trail 105K (The Queen's Race)

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.

Trail 50K (Demanding and spectacular)

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.

Trail 21K (Vertical Half Distance)

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.

Trail 10K (Speed and Introduction)

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.

Registration process and participation requirements

Registration for the Trail 100 Andorra by UTMB are managed directly through the official UTMB World Series platform. Deadlines usually open months in advance, with an early bird period for holders of an UTMB Index active.

1. UTMB Index: A minimum index is not mandatory for registration, but having a valid one will assign you to an optimal starting corral according to your historical performance.
2. Medical certificate: Mandatory for the 105K, 50K, and 21K distances. It must be uploaded, signed by a registered doctor, to the official platform weeks before the race.
3. Accident insurance: The organization provides the required basic coverage, but it is strongly recommended to have federative insurance that covers helicopter rescues in Andorran territory.

Where to sleep in Ordino: Recommended hotels for runners

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:

• Ordino urban axis: Hotels a few meters from the starting line. They allow walking to material check and changing rooms.
• La Cortinada and Ansalonga: Residential areas located just 3-5 minutes by car from Ordino, ideal for those seeking absolute tranquility and spacious apartments for families.
• El Serrat: Located at a higher altitude, ideal if you wish to acclimatize in the days leading up to the event in a purely alpine environment.

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.

What to do in Ordino and Andorra during the weekend

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.

For companions and families with children

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.

For athletes and alpine hiking enthusiasts

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. To organize guided trekking itineraries, canyoning, or adventure activities, explore the options available at Experiences in Andorra.

Tips from a local runner to master the race

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:

• Technical terrain management: The Andorran Pyrenees are unforgiving. Unlike other UTMB events in the Alps where the trails are gentler, here you'll find abundant areas of scree (loose rock), granite boulder fields, and exposed roots in wooded sections. Train long and technical descents thoroughly.
• Altitude acclimatization: A large part of the 105K and 50K takes place above 2,200 meters of altitude, with peaks reaching extreme elevations. Lower oxygen pressure accelerates fatigue and makes digestion difficult. Hydrate constantly and increase your intake of mineral salts from the start.
• Strict mandatory equipment: Weather conditions in the Pyrenees vary in a matter of minutes. A hailstorm or snow at high altitudes in mid-June is perfectly possible. Don't skimp on the weight of your waterproof jacket (minimum 10,000 mm water column) and wear thermal gloves even if the forecast in the valleys is sunny.

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.
