About the Event

Answer the wild call of Northern Portugal’s most iconic mountain range at the Grande Trail Serra d'Arga (GTSA). This premier trail running festival, set against the breathtaking backdrop of the Serra d'Arga from 2nd to 4th October 2026, offers a transformative distance for every ambition. Conquer the legendary GTSA 100KM under a cloak of stars starting in Caminha on October 2nd, or embrace the epic GTSA 50KM journey from Dem at dawn on October 3rd. For those seeking a powerful one-day mountain test, the GTSA 31KM awaits in São Lourenço da Montaria on October 4th, while the vibrant GTSA 17KM provides a stunning gateway to the trails on the same morning. Beyond the runs, immerse yourself in authentic local culture, from folk music to ancient villages, across a meticulously organized weekend that connects runners directly to the soul of the landscape. This is more than a series of races—it's a complete immersion into the rugged beauty, community spirit, and unforgettable challenges of Portugal's verdant north.
