Benasque Great Marathon 2026: all the information about the race

Plan your race pace

On June 13, 2026, Benasque will transform from a picturesque village in the Aragonese Pyrenees into the epicenter of one of Spain’s most powerful trail running events: the Gran Maratón Montañas de Benasque. This high-mountain race offers three distances —42K, 28K, and 19K— all starting and finishing on Avenida de los Tilos, attracting close to 2,000 registered runners from 27 countries. Participants will face a demanding course featuring elevation gain, technical trails, residual snowfields, and the unmistakable character of the Pyrenees.

The race and its unique mountain identity

The Gran Maratón Montañas de Benasque has grown steadily while preserving a rare quality in popular sport: a distinct identity. It is not an alpine ultra styled as a showcase event, nor a bib-bearing pilgrimage. Rooted deeply in the Valle de Benasque inside the Posets-Maladeta Natural Park, the race challenges runners to negotiate terrain, elevation, mindset, and stamina rather than just the clock.

The event is described as a mountain experience rather than a mere sum of kilometers. The 42K course crosses five valleys —Estós, Literola, Vallibierna, Ardonés, and Benasque— and ascends to the area around Pico Estibafreda, offering 44.15 kilometers with 2,699 meters of positive elevation gain. The 28K “Directa al Pico” presents a long, technical climb with panoramic views, while the 19K “Vuelta al Valle de Estós” serves as a more approachable but still challenging entry into Pyrenean trail running.

The terrain and elevation: more than just numbers

Positive elevation gain is a defining element of the Gran Maratón Montañas de Benasque. In mountain races, elevation shapes pace, strategy, and recovery. The 42K’s 2,699 meters of ascent are not mere statistics but a constant presence that dictates how runners manage their effort. The technical terrain includes rocky sections, exposed paths, and variable weather conditions that can rapidly change temperature and footing.

Runners must read the mountain intelligently, pacing themselves by drinking before thirst and eating before hunger, avoiding early bursts that can lead to late fatigue. The race rewards consistency, adaptability, and a measured approach. The varied terrain ensures no monotony: sustained climbs, punishing descents, and altitude that makes every kilometer feel heavier than a flat one.

Setting and atmosphere: Benasque and its community

Benasque, nestled in the heart of the Posets-Maladeta Natural Park, offers a spectacular natural setting that enhances the race’s character. The village and valley are surrounded by major massifs and glacial valleys, creating a mix of openness and rugged relief. This environment shapes both the challenge and the memory runners take home.

The race benefits from the involvement of over 200 volunteers who ensure smooth logistics, safety, and support throughout the course. This human dimension is crucial in a demanding mountain environment, where aid stations, marked crossings, and runner support transform the event into a shared experience rather than a mere competition.

During race weekend, Benasque becomes a vibrant meeting point for runners, companions, locals, and trail enthusiasts, fostering a unique sense of community. This connection between race, territory, and people contributes to the event’s special texture and enduring prestige within Aragonese and Spanish trail running.

Participation and appeal

The 2026 edition sold out its 2,000 bibs in just three months, reflecting the growing appeal of this challenging and authentic mountain race. The distribution of participants among distances —750 in 42K, 750 in 28K, and 500 in 19K— shows the event’s ability to attract a broad spectrum of runners: from seasoned specialists to passionate amateurs seeking a serious mountain experience.

The Gran Maratón Montañas de Benasque is more than a race; it is a gateway into Pyrenean trail running that balances epic endurance with accessibility. It challenges runners physically and mentally while immersing them in one of Spain’s most beautiful and demanding natural settings.
