Travessia das Pontes

The morning sun rises over the capital, finding a community of swimmers gathering at the edge of the lake, where the local clubs prepare their support vessels and markers. This annual gathering, returning for its second edition, has become a core fixture for the local open water circuit, often drawing athletes who look for a different challenge after participating in the nearby circuit events. The atmosphere is defined by the unique geography of the capital, planned in the mid-20th century, which creates a striking contrast between the urban grid and the expansive water of the lake.

The landscape from the water

As you navigate the course, particularly during the 5km test starting at the waterfront, the horizon is dominated by the JK Bridge. Opened in 2002, its steel arches provide a distinct visual rhythm against the sky. Further along the shoreline, the Three Powers Plaza marks the seat of national governance, where the world's largest regularly flown flag ripples in the wind, a sight visible to those swimming in the main channel. The scale of this environment famously led cosmonaut Yuri Gagarin to remark that he felt he had landed on another planet during his visit in 1961.

Life beneath the surface

While moving through the water, you may notice the ecological islands, such as the Ilha do Paranoá, which function as protected nature reserves within the lake. The aquatic environment is shared with native wildlife; it is not uncommon to spot capybaras along the banks or the neotropic cormorant diving for fish. Swimmers might also encounter the jacaretinga, a small, shy caiman species that inhabits the quieter, vegetated shallows. The water itself is often described as temperate by late summer, though the experience remains deeply rooted in the city's identity—a city whose founding, according to local legend, was foretold in a prophetic dream by Saint John Bosco in 1883. For those focused on the history beneath them, the submerged ruins of the Vila Amaury, a settlement from the dam’s construction era, lie silent at the bottom of the reservoir. The competition day itself remains a straightforward test of endurance, with distances ranging from short sprints to the 5km marathon, supported by a system that includes timing chips and official event gear for all finishers.
