Kilian jornet and the utmb: the history of a trail running legend

The Ultra-Trail du Mont-Blanc (UTMB) and Kilian Jornet form a mythical duo in the world of trail running. This iconic 171-kilometre race around the Mont-Blanc massif revealed the exceptional talent of the Catalan runner to the entire world. We look back at the complex relationship between an extraordinary athlete and one of the most prestigious events on the global circuit.

HOW DID KILIAN JORNET MARK THE HISTORY OF THE UTMB?

In 2008, a 20-year-old man disrupted the established codes of trail running. Kilian Jornet, then unknown to the general public, claimed his first victory at the UTMB with an impressive time that already heralded his extraordinary potential. This performance marked the beginning of a legendary career and forever transformed the face of mountain racing.

Kilian Jornet's track record at the UTMB remains etched in memory:

• 2008: First victory at just 20 years old;
• 2009: Second consecutive victory;
• 2011: Third success confirming his dominance;
• 2022: Triumphant return with a historic record of 19h49'30".

This final performance in 2022 remains one of the greatest chapters in the history of the Ultra-Trail du Mont-Blanc. Facing Mathieu Blanchard in an epic duel, Kilian Jornet pushed the limits of what was possible by completing the 171 kilometres and 10,000 metres of positive elevation gain in under 20 hours—a feat that seemed unattainable just a few years prior.

WHY HAS KILIAN JORNET DISTANCED HIMSELF FROM THE UTMB?

Despite his resounding successes, the relationship between Kilian Jornet and the UTMB has progressively deteriorated. The acquisition of the event by the Ironman Group and its transformation into an ultra-commercial global circuit deeply offended the vision of trail running defended by the Spaniard. For him, the very essence of trail running lies in simplicity, authenticity, and respect for the mountain.

In 2023, Kilian reached a turning point by publicly declaring that he would no longer participate in the UTMB as long as the current management remained in place. This courageous stance reflects his deep convictions regarding what trail running should be: an accessible practice, respectful of the environment, and far removed from commercial excesses.

In the spring of 2025, you may have noticed that Kilian lined up for the Chianti Ultra Trail by UTMB, finishing second behind Jim Walmsley. This pragmatic choice shows that despite the tensions, the history between the champion and the UTMB World Series organisation continues to be written, even if it is now on terrains other than Chamonix.

WHAT ARE KILIAN JORNET’S FUTURE PROJECTS IN EUROPE?

The year 2026 promises to be rich in challenges for Kilian Jornet. In a recent interview with L'Équipe, the Spanish runner mentioned his projects while remaining voluntarily evasive about certain details. His qualification for the UTMB, thanks to his result at the Western States, opens up interesting perspectives, even if his participation remains uncertain given his current positions.

Kilian Jornet's projects go far beyond traditional races. His approach to trail running continues to evolve towards ever more personal and creative challenges. Between expeditions in the Himalayas, record ascents on mythical peaks (where wearing a helmet is often mandatory), and races in Europe, the Catalan athlete constantly seeks to push his limits while staying true to his values.

This permanent quest for authenticity and innovation makes Kilian Jornet much more than just a champion. He embodies a specific philosophy of trail running—one that prioritises human experience and a connection with nature over the frantic search for pure performance.

WHAT LEGACY DOES KILIAN JORNET LEAVE TO TRAIL RUNNING?

Kilian Jornet's impact on the world of trail running goes far beyond his victories and records. With four victories at the UTMB, five successes at the Hardrock 100, eleven triumphs at Zegama Aizkorri, and ten victories at Sierre-Zinal, he has redefined the standards of performance and style, popularising the use of speed shades in mountain racing.

Beyond the numbers, Kilian Jornet has, above all, inspired an entire generation of runners to see trail running differently. His ability to combine high-level performance with a deep respect for the mountain environment has paved the way for a more conscious and responsible practice of the sport.

Today, as the debate over the future of trail running and its commercialisation rages on, Kilian Jornet's position serves as a reminder of the importance of preserving the essence of the sport. His refusal to participate in the UTMB under current conditions is not a simple star's whim, but the expression of a coherent vision of what mountain racing should be: free, authentic, and respectful.

The story between Kilian Jornet and the UTMB is likely not over. Recent years have shown that dialogue remains possible, and who knows if one day we will see the Catalan champion treading the trails of the Tour du Mont-Blanc once more. In the meantime, his legacy continues to inspire thousands of enthusiasts who, every day, set out to conquer the summits with the sole ambition of fully living their passion for the mountains.
