The day is enhanced by cultural festivities such as the Dem Folklore Festival, adding a unique community vibe to the challenge. The final day, September 28, is hosted in São Lourenço da Montaria, offering four diverse races: the GTSA 31KM, GTSA 17KM, a 12KM Hike, and a Kids Race. These circular routes showcase the natural beauty of the region, passing forests, waterfalls, and traditional villages, with distances suited to competitive runners, nature lovers, and families alike. From night-time ultras to festive hikes, GTSA 2025 promises a dynamic celebration of sport, culture, and the wild Serra d’Arga landscapes.
