Zegama-Aizkorri 2025: The Mountain Marathon That Defines Grit and Glory

ZEGAMA, SPAIN — On Sunday, May 25, 2025, the world’s most electrifying trail marathon returns to the rugged peaks of the Basque Country. The Zegama-Aizkorri Mountain Marathon, now in its 24th edition, is more than a race—it’s a rite of passage for mountain runners.

Each year, hundreds of elite and amateur athletes are drawn to the small village of Zegama to test themselves on a course that is as breathtaking as it is brutal. With 42.195 kilometers (26.2 miles) of steep, technical terrain and 2,736 meters (8,976 feet) of vertical gain, the challenge is legendary.

A Look Back at 2024: Jornet and Nordskar Shine

In 2024, trail running legend Kilian Jornet claimed his 11th Zegama title, completing the course in 3:38:07, the second-fastest time in the race’s history. The Spaniard’s unmatched mastery of this terrain—where weather, altitude, and technicality collide—continues to amaze.

On the women’s side, Norway’s Sylvia Nordskar delivered a breakthrough performance, winning in 4:29:12. Her victory came after years of chasing a podium finish, cementing her place among the world’s best mountain runners.

What Makes Zegama So Unique?

Zegama's course runs through the Aizkorri-Aratz Natural Park, an untouched alpine landscape of jagged ridges, mossy forests, and sweeping vistas. But it’s not just the scenery that defines Zegama—it’s the intensity of the terrain:

• Brutal Climbs: Runners face punishing ascents like Sancti Spiritu, where fans line both sides of the narrow path, turning the mountain into a human tunnel of noise and encouragement.

• Technical Descents: Slippery rock faces and steep downhills test a runner’s balance and nerve, often under unpredictable weather that can shift from fog to freezing rain in minutes.

• Unmatched Atmosphere: Thousands of passionate Basque fans hike deep into the mountains to cheer with cowbells, flags, and chants. It’s been compared to the Tour de France on foot.

In Zegama, you’re not just running against the clock—you’re running with the crowd, through weather, over stone, and into history.

2025 Expectations

With another stacked field expected for 2025, the stage is set for drama. Can Jornet make it 12 wins? Will Nordskar defend her title? Or will a new name rise through the mist?

One thing is certain: Zegama es Zegama. No other race captures the raw essence of mountain running like this one.
