River— Argentina

XXIII Cruce del Yaguaron

Nov 29, 2026
Distances: 3km and 8km
23rd edition

About the race

The Yaguarón flows as a silent witness to the turbulent history of the Paraná riverbanks, acting as the final passage for the Arroyo del Medio before it merges with the greater Paraná river. To swim here is to trace a path where the depth reaches 34 feet in the port zone, a necessity for the large cargo vessels that navigate upstream from the Atlantic. The water often carries the weight of its past; beneath the surface of this confluence, one finds the echoes of the 1811 Battle of San Nicolás, where royalist fleets and revolutionary forces engaged in the first naval clash of the region. As you stroke through the channel, you are traversing the same currents that saw the Spanish royalist squadron conduct their 1812 looting of the town to secure supplies for Montevideo.

## Race day logistics

The XXIII Cruce del Yaguaron, organized by the Club Belgrano, brings swimmers together for an integration race of 3000m and a competitive 8000m event. The scale of the organization—transferring hundreds of participants to the starting point—is reflected in the registration fees, which are set to cover necessary logistics like site access and comprehensive medical assistance. Participants receive a kit containing a t-shirt, swimming cap, medal, and a cereal bar. While the 8km event is the main draw for those seeking a longer challenge, the venue remains a place where local pride is deeply felt, often linked to the legacy of local figures like football icon Omar Sívori. The city itself is also remembered for the Acuerdo de San Nicolás of 1852, a foundational pact that helped shape the nation. Swimmers should note the strict time limits enforced on the water, a safety protocol essential for managing the river's flow during the race. For those looking to compare their strength against other currents, the local calendar includes events like the Travesía Fabio Guerzoni in nearby Ramallo or the Desafío de la Ribera, which also utilizes these river systems.

Where to stay

San Nicolás offers a mix of modest urban hotels and comfortable guesthouses near the riverfront, catering to those who prefer proximity to the club’s base. You will find several regional hotels and boutique stays in the city center within walking distance of the port, with rates typically ranging from $40 to $90 per night depending on the level of service. For a more relaxed atmosphere, some visitors opt for local lodges situated slightly further along the riverbank.

Things to do nearby

The area is defined by its strong historical ties to the independence movement. Beyond the race, you can explore the preserved colonial architecture in the city center or visit the sites associated with the 1852 national pact. The riverfront is the hub for local activity; many swimmers spend their post-race hours at regional riverside grills, known as parrillas, or take to the water in kayaks to explore the quieter branches of the Paraná delta, which offer a sharp contrast to the main channel's current.
