El Cruce 2026 in Bariloche: The world’s largest stage trail running race
El Cruce 2026 comes to Bariloche from December 5 to 11: 100 km over 3 days through the Patagonian mountains, with two lakeside camps. Everything you need to know about the largest multi-stage trail race in the world.
Some races you run; others you live. El Cruce is the second kind. For three days, hundreds of runners from around the world head deep into the Patagonian Andes to cross mountains, ford rivers and sleep under the stars, far from everything. In 2026 the meeting point is Bariloche, from December 5 to 11, in what is already the 24th edition of the largest multi-stage trail running race on the planet.
What El Cruce is
El Cruce was born in 2002 with an idea as simple as it was ambitious: to cross the Andes on foot, linking Argentina and Chile through the mountain passes. More than two decades later it has become a classic of adventure racing, an experience that blends physical demand, unique landscapes and a logistics setup designed so every runner can focus on one thing: finishing.
This is no ordinary race. It is a stage journey where the route changes every year and, at the request of private landowners and local communities, is not revealed until the day before the start. That touch of mystery is part of its essence: discovering new terrain in every edition.
El Cruce 2026: Bariloche and Cerro Catedral
The 2026 edition is based at Cerro Catedral, Bariloche, in the province of Rio Negro. That is where accreditation, the opening ceremony, the start of the first stage and the final finish all take place. During those days the city turns into the capital of mountain trail running, with runners from more than 45 countries arriving to take on the challenge.
The format: 100 km over 3 days
El Cruce 2026 is 100 kilometers split into three stages, with two lakeside camps as rest points. To protect the experience and the logistics, runners are split into five start groups that race on consecutive dates within the same week. Everyone runs the same stages, the same route and the same camps; the only thing that changes is the day they begin.
One thing is worth knowing from the start: the cut-off time is 15 minutes per kilometer. Anyone who does not reach the checkpoints within that limit cannot continue the stage. That is why El Cruce rewards both preparation and heart.
The terrain and the challenge
The route is pure Patagonian landscape: mountain trails, ridgelines overlooking the lakes, forests, river crossings, streams and beaches that look like another world. The weather matches that intensity. Even though the race is held in summer, in Patagonia you can go from a sunny 20-degree day to cold, wind, rain or even snow within hours. Packing the right gear and training ahead of time is not just advice: it is the difference between enjoying and suffering.
The camps: sleeping in the mountains
A big part of the magic of El Cruce happens at the camps. After each stage, runners arrive at a camp set up in one of the most beautiful corners of Patagonia, with two-person tents, full meals, water and spots to soak their legs in the lake and recover. There are also services built for the body: massages, compression boots, GPS and phone charging, and a screen showing the photos and videos of the day.
Eat, rest, chat with runners from all over the world and get ready for the next stage. That routine, repeated over three days, is what many describe as the real El Cruce experience.
How to take part
Registration for El Cruce 2026 opens on February 10, through the EntryFee platform or in person at Club de Corredores in Buenos Aires. There are also offices across the country and abroad. To race, every runner must present a medical fitness certificate, which can be handed in at accreditation or uploaded online before the stated date.
And if the adventure tempts you but you are not ready for 100 km yet, El Cruce also offers La Etapa, with 15 km and 33 km distances for those who want to feel the spirit of the race in a shorter format.
Why it is worth it
El Cruce is not just a competition: it is a week where body, mind and landscape are all tested at once. Those who finish take home more than a medal; they take the memory of having crossed Patagonia on their own legs. As those who have run it say, not everyone can race it, but whoever does will never forget it.
