Travesía Internacional Amazónica

The legend of the Ikitu people tells of a desperate flight from their ancestral lands to escape the wrath of a 'demon tiger,' an event that etched the name 'ikitu'—meaning 'tiger'—into the very soil of this region. Today, swimmers who arrive in Iquitos to tackle the Travesía Internacional Amazónica find themselves tracing the liquid arteries of that same jungle, where the human struggle against nature is not a myth but a tangible reality. The race unfolds in the Amazon, an environment where the water is a living, shifting entity. Participants navigate the complex confluence of the Nanay, a blackwater river that moves with a slow, deliberate cadence. Its winding path is defined by 'caños'—natural canals—that during the rainy season breach their banks, flooding the lowlands and creating a labyrinthine landscape that changes from one year to the next.

The jungle from the water

As you swim, the modern world feels distant, yet landmarks of human ambition pierce the skyline. You will pass beneath the Nanay Bridge, a 2,283-meter feat of engineering that stands as the longest in Peru, connecting the Bellavista-Nanay neighborhood to the quiet reaches of Santo Tomás. The route is steeped in stories of those who probed these waters long before the race began; Captain Archibald Butt of the US Navy famously ascended 314 kilometers of the Nanay, testing the limits of its navigability. In the surrounding areas, the landscape is dotted with historical markers like the Casa Fitzcarraldo in Punchana, a site that once served as the operational base for Werner Herzog's cinematic explorations of the jungle.

Race day and legacy

The event is a test of endurance across 50,000 meters, a distance that demands respect for the river’s immense scale and its unpredictable seasonal shifts. Iquitos itself is an anomaly of the jungle, a city that once saw the 'Casa de Fierro'—a structure prefabricated in Belgium—carried in hundreds of pieces through the forest by men on foot, only to be reassembled in the heat of the tropics. This spirit of improbable construction mirrors the commitment required to complete this marathon swim. The race remains an annual pilgrimage for those looking to experience the Amazon not from the safety of a boat, but from the surface of its deep, dark waters, where the current dictates the pace and the jungle provides the only backdrop.
