Semi-Marathon Formentera 2026

Semi-Marathon Formentera offers a half marathon and an 8 km race on Formentera, a small Balearic island south of Ibiza. The main race is limited to 2,000 participants, and the 8 km race has 1,000 spots. Runners are chosen by lottery because of the event receiving more applications than available places annually. The appeal lies in runners crossing parts of Formentera’s open island terrain, with the course integrated into natural surroundings instead of a typical urban setting. The Government of the Balearic Islands and the Balearic Islands Tourism Agency support the event, which organizers associate with sustainable sports tourism and consider a leading running event in Spain and internationally.
