SPD San Pedro — Circuito OWA

Nov 15, 2026
Distances from 1.5km to 7km

About the race

The current of the Paraná River pulls you forward, blurring the distant greenery of the delta islands that frame your horizon. As you settle into your rhythm, your hand occasionally brushes against the silty water, a riverbed that holds the fossilized history of over twenty prehistoric mammal species. Ahead, the riverbank rises into the sharp, imposing barranca cliffs, natural sentinels that have watched over these waters long before the city of San Pedro was founded. You are in the middle of the SPD, a gathering that turns the river into a shared path for swimmers of all levels.

The River and its Stories

Navigating these waters means crossing paths with layers of human history. On the 7km course, miscalculating your finish is easy if you lose focus: once you glide past the ARA Irigoyen—the former US Navy tug now resting as a museum ship—you know you have already overshot the final stretch. The banks here whisper of the Battle of Vuelta de Obligado, a 19th-century confrontation where local forces stood against foreign blockades, a reminder of the strategic importance of this channel. Even further back, the area reveals the legacy of the Querandí, whose ancient settlements were unearthed just decades ago, grounding your swim in a deep, indigenous past.

Race Day Logistics

Scheduled for November 15, 2026, the SPD offers distances of 1.5km, 4km, and 7km, all designed as point-to-point downstream swims. The logistics are extensive, requiring shuttles to transport athletes to the start lines upstream to capitalize on the river's flow. For the 4K and 7K events, wetsuits are optional and placed in separate ranking categories, while the 1.5km Super Sprint strictly forbids them to ensure a pure test of speed. If you are looking for a different pace, those seeking a varied challenge often pair their visit with the VOB held just the day before. With water temperatures typically sitting between 23°C and 26°C, the river remains a constant companion, demanding respect for its current and its hidden, prehistoric depths.
