Extremo Sul Ultramarathon

The Extremo Sul Ultramarathon is an extraordinary race that invites participants to test their endurance and resilience across a vast 226 km route (140 miles). Set in Brazil’s southernmost region, the course stretches from Barra do Chuí in Santa Vitória to Cassino in Rio Grande, along the world’s longest beach. This self-sufficient race must be completed within a 52-hour limit, demanding participants to carry their own supplies and navigate a shifting, ever-changing terrain where the boundary between sea and sand fades into an endless horizon. With several checkpoints along the way, this challenge is as much about mental fortitude as physical strength, making it an unparalleled adventure for those seeking to push the limits of endurance.
