Each race starts at different park locations—including Vila do Gerês, Castro de Laboreiro, and Fronteira Portela do Homem—ensuring immersive landscape and cultural experiences. Organized by Carlos Sá Nature Events with support from the Terras de Bouro municipality, the event provides marked routes, aid stations, and a vibrant atmosphere, delivering an unforgettable mountain-running adventure. With stunning natural backdrops and diverse challenges, the Gerês Extreme Marathon is a true highlight of Europe’s trail-running calendar.
