SPD San Pedro — Circuito OWA

The current of the Paraná River pulls steadily beneath you, a powerful reminder of the complex delta system that defines this stretch of the Argentine landscape. As you sight forward, the prominent barranca cliffs of San Pedro rise sharply from the water’s edge, serving as a natural navigational landmark that has guided travelers here for generations. This terrain is more than just a scenic backdrop; the riverbanks surrounding these waters are renowned for their paleontological significance, housing prehistoric deposits that have yielded remains of over twenty species of fossil mammals, now preserved in the local museum.

This is the setting for the SPD San Pedro, a signature event of the OWA Circuit taking place on November 15, 2026. Whether you are tackling the 7K, which scores points for the circuit, the intermediate 4K, or the dynamic 1.5K, the experience is anchored in a deep sense of community. The event is hosted at the Camping América, a location that mirrors the social spirit of the race. While the competitive focus is clear, the day is designed to be inclusive, welcoming those who are testing their limits in open water for the first time alongside seasoned swimmers.

Race day logistics

The organization prioritizes a safe, well-supported environment, utilizing a comprehensive water safety protocol that includes support boats and lifeguards. For the 2026 edition, a significant technical upgrade has been introduced: the implementation of chip timing to ensure accuracy across all categories. Participation requires an official medical clearance dated within 90 days, and the use of a safety buoy is mandatory for every swimmer. Wetsuits are optional, though swimmers choosing to wear them will be placed in a separate classification.

As you navigate the course, you may catch a glimpse of the ARA Irigoyen, a former US Navy vessel now serving as a museum ship in the port, standing as a silent witness to the history of these waters. Your journey here also keeps the spirit of the local heritage alive, much like the swimmers who gather nearby for the Vuelta de Obligado just one day prior. With entries ranging up to 180,000 ARS, the event includes an official kit, a finisher medal, and full medical coverage, ensuring that every participant—regardless of distance—receives the same professional support as they emerge from the Paraná.
