The infamous 2026 Zegama-Aizkorri Marathon celebrates its 25th edition with a giant elite field and a long weekend of celebration. Tens of thousands of spectators are expected to fill the mountains and valley surrounding the small village of Zegama in Basque Country, Spain. iRunFar is excited to join the celebrations and share stories from the event!

The race takes place on Sunday, May 17, at 9 a.m. local time (1 a.m. U.S. Mountain Daylight Time).
The race course is a loop starting and finishing in Zegama, and taking in a technical and aesthetic line through the Aizkorri Massif. Over its 42 kilometers (26.2 miles), there are 2,736 meters (8,976 feet) of climbing. The course has extremely technical sections as well as some glorious runnable singletrack and doubletrack, making something for every kind of runner, but those used to the vertical change and roughness of mountain running are most likely to excel here.

Given the course has been raced so many times by fast athletes and hasn’t changed, course-record-setting is generally limited to years with good weather — when it’s neither too hot nor too muddy. The year 2022 was a great weather year, and that’s where both Kilian Jornet and Nienke Brinkman set the current men’s and women’s course records of 3:36:40 and 4:16:43.
We’ll be live blogging the race over on iRunFar’s X feed with text and photo reports from all over the course. We’ll also be live blogging the same material below in this article. Follow along!
