Triatlón Challenge Islas Cíes 2026

Triatlón Challenge Islas Cíes is a Half Ironman-distance triathlon in Vigo, on Spain’s Atlantic coast in Pontevedra, Galicia. It takes place in mid-September, offering athletes the standard long-course challenge: 1.9 km swimming, 90 km road cycling, and a 21.1 km road run. The race utilizes Vigo’s coastal environment instead of being confined to city streets. The course features seaside sections, sand, urban roads, and natural areas, making the day more than a simple road race. Athletes of various skill levels compete, and the event is organized as a professional sporting competition, not a casual beach event.
