Circuito Maratour — Itaparica (novembro)

The waters surrounding Itaparica are not merely a backdrop for swimming; they are a vast, salt-heavy expanse of the Baía de Todos os Santos that rhythmically pulse with the Atlantic tide. Navigating this bay requires an understanding of how the water moves between the mainland and the island, creating channels where the current can shift significantly as the tide turns. When you swim here, you are moving through a maritime corridor that has defined local life for centuries. You might feel the shift in density as you drift away from the shallow, mineral-rich coastlines toward the deeper, more turbulent center of the bay, where the history of colonial maritime defense still anchors the seabed.

Historical currents and landmarks

As you sight your next marker, the silhouette of the Forte de São Lourenço emerges from the shoreline. Built by the Dutch during their 17th-century occupation, this stone sentinel has witnessed centuries of territorial struggle, including the fierce battles for the Independence of Bahia that once roiled these same waters. The area’s maritime legacy is deeper than its fortifications; from the 17th to the 19th century, these bays were primary hubs for the whaling industry, with processing stations at Ponta de Itaparica and Ponta da Cruz. While the whales have long since migrated elsewhere, the deep-water channels they once frequented now host the 16km ultramarathon course.

This event is part of a broader culture of long-distance swimming in Bahia, echoing the tradition of the famous 12km Travessia Itaparica-Salvador, a historic race dating back to 1955 that has seen legends like pentachampion Lourival Quirino and a young Ana Marcela Cunha claim victory. For those seeking a different challenge in the region, the Maratour Village Itaparica offers shorter, high-intensity distances just a day before the main ultra event. Whether you are tackling the full 16km or the shorter circuits, you are participating in a tradition that connects the island's colonial past to its modern status as a destination for serious open water athletes. Amerigo Vespucci first charted this bay on All Saints' Day in 1501, and the strategic importance that drew early explorers remains visible in the way the local geography dictates the race line today.
