Carrerira Ao Son Do Masma 2026

Ao Son do Masma is a 5.6 km asphalt race in Barreiros, Lugo, Galicia, typically held in November. It serves as the final event of the Circuito +Kms Barreiros. The primary race begins at midday, following a 10:30 walking event, or andaina, and children's races at 11:00. Organized by the cultural collective Ollomao and the Concello de Barreiros, the day is designed for local runners, families, walkers, and children, not exclusively competitive club athletes. The course traces the Masma River, offering a straightforward, open-air route that avoids becoming an endurance test. Its position at the conclusion of the circuit adds significance, as final category standings can be determined there. The broader Circuito +Kms Barreiros also covers the Carreira Solidaria de Reis, Carreira das Praias, 1/2 Km Vertical, and Trail Monte Comado. This arrangement makes Ao Son do Masma the concluding event in a local series featuring a mix of road running, beach routes, vertical racing, and trail running.
