Ironman 70.3 Marbella 2026

Ironman 70.3 Marbella is a Half Ironman race in Marbella, on Spain’s Costa del Sol in Andalusia. Athletes race the standard 70.3-mile format: a 1.9 km swim, a 90 km road bike leg, and a 21.1 km road run. The event sits inside the wider Ironman circuit and is scheduled around the end of October, so it comes late in the triathlon season. The course uses Marbella’s city setting while also pulling in the coast, nearby mountains, and natural areas around the Province of Malaga. Marbella also appears on the Ironman 70.3 World Championship host list, linking the race to the top international competition for this distance, organized by the World Triathlon Corporation since 2006. The wider Ironman 70.3 Pro Series runs from March to October, and its fields include professional triathletes chasing points across multiple races, while Ironman’s club, beginner, women’s, ranking, and rules resources show how much of the ecosystem is built around age-group athletes as well as pros.
