Fundación Pura Voluntad
More Than a Race
El Reto del Indio was born out of pure passion by a group of trail friends. There are no corporate owners or profits: it is a non-profit organization where 100% of proceeds are reinvested into the event and the indigenous river communities along the course.
"Camaraderie, friendship, and positive energy. That is the essence of El Reto del Indio, and that is what we leave behind in every village."
The Reto Family
El Reto del Indio started with a group of friends and remains just that: a family crossing Panama together through laughs, mud, and warm embraces at every aid station. Here nobody runs alone — runners, volunteers, and Río Indio locals make the journey unforgettable.
