Backyard Ultra Platja d’Aro

Backyard Ultra Platja d'Aro is a trail ultrarunning race held at the Sala Polivalent in Castell d'Aro, Girona. Participants follow the Backyard Ultra format: a 6.7 km loop with 23 meters of elevation gain per lap, completed each hour. The race continues until one runner outlasts all others by completing an additional loop. The course crosses Castell d'Aro, Platja d'Aro, and S'Agaró. The competition emphasizes sustained pace, resource management, and fatigue control over a single maximal effort. Organized by Tritons de la Vall d'Aro, the event has limited entries and is designed for experienced endurance runners seeking a tactical challenge rather than a conventional finish line.
