Set in the majestic Peneda-Gerês National Park, the Gerês Extreme Marathon unfolds over three days from December 5–7, 2025, offering a spectacular blend of endurance and nature. Participants navigate diverse terrains—from mountain roads to trails—choosing from six event distances: the rapid Extreme Mile (1.6 km), a new 12 km race, the punishing 90 km ultra, a classic marathon (42 km), the 32 km middle distance, a scenic half marathon (21 km), and a mini 14 km route. 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.
