The prestigious Ultra Trail Mont Blanc (UTMB) has chosen Ushuaia, Argentina, as the host city for its upcoming edition, under the name “Valhöll Fin del Mundo by UTMB 2025”. This historic event will mark a milestone in the South American sports calendar, establishing Argentina as a key destination for trail running on the global stage.

The world’s most prestigious race chooses Argentina

The competition will take place from March 18 to 22, 2025, attracting approximately 2,000 elite athletes and amateur runners from around the world. This decision was no coincidence—it was the result of a competitive selection process in which Ushuaia outperformed numerous Latin American cities to earn the right to host this iconic event.

El Instituto Fueguino de Turismo confirmó que la provincia recibirá a miles de corredores internacionales y nacionales, quienes llegarán acompañados por sus familias, entrenadores y equipos de running. Además, los participantes que completen las categorías correspondientes obtendrán Running Stones, fundamentales para el sorteo del UTMB Mont-Blanc.

Ushuaia Becomes the Stage for the ‘End of the World’ Race

The capital of Tierra del Fuego will offer a unique setting that combines all the landscapes and terrains of the southern Andes. Runners will traverse:

• Subantarctic forests
• Rocky terrain and glaciers
• Lakes and rivers
• Peat bogs and mountains.

Due to its privileged location near Antarctica, the mountains surrounding Ushuaia—rising between 1,000 and 1,500 meters—offer climatic conditions similar to those found in the Alps at 2,500 to 3,000 meters of elevation.

The competition will uphold the highest standards of quality and safety, following a non-stop technical format under the principle of semi-autonomy. Participants must remain self-sufficient between aid stations while facing significant elevation changes and varied terrain.

Particularly significant is the fact that the top three finishers—both male and female—in the 100M, 100K, and 50K categories will receive automatic qualification for the UTMB®, CCC®, and OCC races, respectively. This unique opportunity positions Valhöll Argentina by UTMB as a gateway to the UTMB World Series Finals in Chamonix.

The event not only represents an exceptional athletic challenge but also a significant boost for regional tourism. According to local authorities, the competition will generate substantial economic activity, benefiting sectors such as hospitality, gastronomy, retail, and tourism service providers.

The organizers have confirmed that they will use the same runner tracking system and medical software employed at UTMB® Mont-Blanc, thereby ensuring the highest safety standards for all participants.

Gonzalo Castillo, General Director of Valhöll Fin del Mundo by UTMB, highlighted the excitement expressed by top international runners at the prospect of competing at the End of the World destination. Meanwhile, Florencia Madero, General Coordinator, emphasized that this event will showcase both Argentina and the End of the World to the world, promising an extraordinary adventure for all visitors.

Valhöll Fin del Mundo: Extreme Course

Valhöll Fin del Mundo by Ultra Trail Mont Blanc is set to deliver an unprecedented experience in the world of trail running. This extraordinary event, scheduled for March 18–22, 2025, will transform Ushuaia into the global epicenter of mountain sports.

The southernmost challenge on the planet

The competition will take place in a unique setting where glacial valleys, peat bogs, and ancient forests create a spectacular backdrop for the participants.

The organizers expect to welcome approximately 2,800 runners, 45% of whom will be international athletes representing 53 different nationalities. This international event will kick off from the iconic Plaza Islas Malvinas, where participants will begin their adventure toward the End of the World.

Technical Features of the Main Course

The main course includes the following categories, each with its own specific features:

• EPIC 130KThe main event features 130.7 kilometers with a positive elevation gain of 5,721 meters.
• ADVANCE 85K: A 86-kilometer course with 3,704 meters of positive elevation gain.
• CHALLENGE 50K: A 51.6-kilometer route with 2,785 meters of elevation gain.
• COURAGE 32K: A 32.8-kilometer distance with 1,595 meters of ascent.
• POWER 22K: A 23.8-kilometer course with 929 meters of elevation gain.
• EXPLORE 12K: The most accessible route covers 13.4 kilometers with 684 meters of elevation gain.

The course design takes full advantage of Tierra del Fuego’s unique geography, incorporating natural elements that will challenge participants. Runners will pass through a variety of ecosystems, from subantarctic forests to high mountain areas.

The competition will maintain the same high standards of quality and safety that define the Ultra Trail Mont Blanc. To ensure participant safety, the same runner tracking system and medical software used in the European race will be implemented.

The organizers are already in the capital of Tierra del Fuego carrying out preliminary logistics work, ensuring that every detail is perfectly coordinated to deliver an exceptional experience. Likewise, the event has been designed to preserve its vibrant and challenging spirit—the very characteristics that have distinguished it in previous editions.

The race will follow the principle of semi-autonomy, meaning that runners must be self-sufficient between designated checkpoints. This format adds an extra level of challenge, requiring thorough preparation from all participants.

Runners will face unique weather conditions

The extreme weather conditions of Tierra del Fuego present a unique challenge for participants of Valhöll Fin del Mundo by Ultra Trail Mont Blanc. Its proximity to Antarctica creates a climate similar to that of the Alps at 3,000 meters of elevation, making this race an extraordinary test of endurance and adaptability.

The Patagonian wind as a key obstacle

Patagonian winds represent one of the greatest challenges for runners. During the race, gusts can reach speeds of up to 80 km/h (50 mph), forcing athletes to maintain constant balance while navigating mountainous terrain. Although the strong spring and summer winds usually ease during the time of the event, conditions can shift dramatically within minutes.

To ensure the safety of all participants, the organization has implemented specific measures:

• Constant monitoring of weather conditions
• Mandatory safety equipment
• Real-time runner tracking system
• Specialized mountain rescue personnel

Preparedness for extreme temperatures and sudden weather changes

Temperatures along the course can vary significantly. During the day, valleys may reach up to 11°C (52°F), while in the mountainous areas—especially at night—temperatures can drop below -10°C (14°F). This wide thermal range requires meticulous preparation from all runners.

The unique geographical location of Ushuaia allows for the experience of all four seasons in a single day. Therefore, participants must develop a true sense of personal autonomy to manage:

• Sudden weather changes
• Extreme nighttime conditions
• Dense fog situations
• Rain or snowfall

In the event of adverse weather conditions, the organization reserves the right to modify the routes or shorten the distances to ensure the safety of participants. However, the race will not be cancelled due to bad weather, except in truly extreme situations.

The experience from previous editions has highlighted the importance of these measures. For example, in the first edition, 86% of the runners managed to complete the race despite facing extreme weather conditions, setting a precedent similar to that of the 2003 Ultra Trail Mont Blanc.

Average summer temperatures range between 8°C and 17°C (46°F to 63°F), although these figures can vary significantly in the mountainous areas. For this reason, it is essential that runners arrive at the starting line with all the required equipment, as failure to do so may result in penalties or even disqualification.

CHALLENGE 50K attracts intermediate runners

The CHALLENGE 50K category of Valhöll Fin del Mundo by UTMB positions itself as an appealing option for intermediate-level runners looking to delve into the world of high-mountain trail running. This 51.6-kilometer course features 2,785 meters of positive elevation gain, offering a balance between technical challenge and accessibility. Runners will encounter:

• Mountain passages such as Tristen and The French
• Notable elevations such as Cerro Bonete and Monte Cortez
• Panoramic views of La Cloche Mountain, which rises 1,000 meters above sea level

Throughout the course, athletes will experience significant elevation changes while enjoying privileged views of the Beagle Channel. The route has been designed to offer a comprehensive experience of the Fuegian terrain, allowing runners to appreciate the unique beauty of the End of the World.

Checkpoints and aid stations

The organization has established a comprehensive support system to ensure the safety and well-being of all participants. Aid stations are strategically located along the course, offering:

• Drinks and food for on-site consumption
• Ongoing medical assistance
• Mandatory checkpoint control

To ensure safety, the organization conducts random checks at various points along the course, in addition to those established at the aid stations. Only participants wearing their bib visibly and correctly positioned will have access to support services.

The tracking system used is the same as that employed in the Ultra Trail Mont Blanc, ensuring accurate monitoring of each runner. In addition, the medical software implemented guarantees a rapid response in case of any emergency, upholding the high safety standards characteristic of UTMB® races.

The previous edition saw over 100 runners, and participation is expected to increase significantly in 2025, given the growing international interest in the event. Organizers are already in Ushuaia carrying out preliminary logistics work to ensure an exceptional experience.

• Manage their hydration (minimum 1-liter capacity)
• Carry energy food with them
• Carry mandatory equipment for adverse weather conditions

The maximum time set to complete the course is generous, allowing participants to enjoy the experience without the pressure of a demanding pace. However, it is crucial for runners to prepare adequately to face the challenges of the terrain and the changing weather conditions characteristic of the region.

3. Acclimatization: Arriving early in Ushuaia allows participants to adapt to the local conditions and explore part of the terrain.

It is important to note that although EXPLORE 12K is the most accessible category, the weather conditions in Tierra del Fuego can present significant challenges. Participants must be prepared for:

• Sudden temperature changes
• Strong winds characteristic of the Patagonian region
• Possibility of rain or even snow

The event, scheduled for March 21, 2025, coincides with the end of the Southern Hemisphere summer, offering generally more favorable conditions. However, the unpredictable nature of the weather at the End of the World adds an element of adventure to the experience.
