Half Madrid Triatlón 2026

Half Madrid Triatlón is a new triathlon based in Madrid’s Casa de Campo, with Puente del Rey also part of the event area. The race offers three distances, and the middle-distance event also serves as the Madrid Middle Distance Championship. The race hub sits around the lake in Casa de Campo, one of the city’s biggest green spaces and a familiar training area for Madrid athletes. It also counts toward Spain’s national middle- and long-distance ranking, so it draws competitors chasing federation points as well as triathletes targeting a major local title.
