Gorbeia Suzien 2026

Gorbeia Suzien is a Basque mountain skyrace held in Zeanuri, Biscay, northern Spain, typically in late September. The primary 32 km race is a demanding loop within Gorbeia Natural Park, featuring approximately 2,400 meters of elevation gain and a 6.5-hour time limit. A 21 km option is also available for those seeking a shorter mountain race. The course ascends through woodland, reaches exposed rocky ridges, and descends on fast, technical sections. Its highest point is near the Mount Gorbea cross, around 1,480 meters. The event is part of the Skyrunner World Series and is known as the “Zegama bizkaína,” referencing the rich Basque skyrunning tradition that attracts both elite mountain athletes and local trail runners.
