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.
