Reto Acapulco La Prueba Reina

Reto Acapulco La Prueba Reina offers marathon swimming across three distinct distances: 6.4km, 11km, and a 22km ultra-marathon. Scheduled for November 7, 2026, the event takes place in the open waters of the Bahía de Acapulco, a natural harbor that has shaped the maritime history of the Mexican Pacific for centuries. Swimmers navigating these waters follow routes that pass by the shoreline where geological and military events have left permanent marks on the landscape. Unlike the colder currents found further north along the Pacific coast, this bay maintains a distinct warmth that requires careful hydration and energy management for the longer 22km category.

A landscape of fortifications

As you progress along the coast, the geography tells a story of strategic defense. You will be swimming within sight of the Fort of San Diego, a pentagonal structure rebuilt in the late 18th century to safeguard the port against privateers. The bay's defensive significance peaked during the 17th century; specifically, the 1615 Dutch pirate invasion caused such extensive damage that it forced a total rethink of the port’s security. Further along the line of sight, the Cerro de La Mira remains a reference point for the 1863 resistance, where the Fortín Álvarez withstood a two-day naval bombardment during the French intervention. The history of these waters is not merely one of defense but also of intense conflict, such as the 1813 Siege of Acapulco, where revolutionary forces led by José María Morelos isolated the city, effectively halting the trade routes that once linked these shores to Asia. While modern swimmers may admire the steep cliffs where the famous La Quebrada cliff divers operate, the bay has also witnessed volatile natural phenomena; in 1820, a seismic event caused the sea to retreat 10 meters, before returning in a massive 4.5-meter surge that reshaped the coastal geography. Today, the water remains a hub for endurance, often seen as a longer, more solitary challenge compared to the shorter Roqueta Weekend held in the same waters earlier in the season.
