SPD San Pedro — Circuito OWA

The current of the Paraná River pulls steadily against your stroke as you navigate the wide channel, where the distant silhouette of the ARA Irigoyen museum ship emerges from the morning haze. To your right, the shoreline rises into the distinctive barranca cliffs, natural earthen walls that have defined this landscape for millennia and now serve as your primary navigational reference. Beneath the water, you are swimming over a region of profound geological history; the riverbanks here are known for significant fossil deposits, where remains of prehistoric mammals have been unearthed by local researchers. This environment, shaped by the complex Paraná Delta island system, provides the backdrop for the SPD San Pedro, a central event within the OWA Circuit.

Race day logistics

Organized by OWA, the event returns on November 15, 2026, centering its operations at Camping América. The race program features a 7K main distance, which awards points for the circuit, alongside a 4K intermediate option and a 1.5K short-course format. For those familiar with the local racing calendar, this event follows closely behind the Vuelta de Obligado held just days earlier, allowing athletes to experience different segments of the same river system. Participation requires a medical clearance issued within 90 days of the race, and all swimmers must utilize a safety buoy. While the use of a wetsuit is optional, those choosing to wear one will be placed in a separate classification. The registration fees, which reach up to 180,000 ARS for the longest distance, cover the logistics of river safety, including patrol boats and medical support, ensuring a controlled environment for all skill levels. Competitors receive an official kit, a finisher medal, and a T-shirt as part of their entry. As you push through the final stretch, the sight of the cliffs and the surrounding delta islands reminds you of the deep historical layers of the region, from the ancient fossil beds to the 19th-century sites where local forces once defended the riverbanks.
