RIVER ANDJUNGLEMARATHON
"Run where the forest meets the river.
Push your limits in the greatest Amazon adventure."
Countdown to race day
A Race That Connects
You to the Living Amazon
The River and Jungle Marathon (MRS) is an international trail running marathon held in the heart of the Brazilian Amazon, in the community of Pindobal, Belterra, Pará. A unique event that combines physical challenge with the incomparable beauty of the world's largest tropical rainforest.
Running through trails between rivers, dense forests, and landscapes that few have the privilege of knowing, the MRS is much more than a race — it is a transformative experience that connects athletes from around the world to nature in its purest and most wild form.
Our goal is to promote high-performance sport combined with sustainable tourism, valuing local culture, Amazonian biodiversity, and respect for the environment. Every step taken in this race is a step toward adventure and self-transcendence.
