XVIII Maratón Aguas Abiertas Bacalar 2026

Om løbet

The XVIII Maratón Aguas Abiertas Bacalar 2026 invites swimmers to experience one of the most breathtaking natural wonders in Mexico: the 'Lagoon of Seven Colors'. Located in the heart of Quintana Roo, Bacalar is a magical town (Pueblo Mágico) defined by its crystal-clear, shallow freshwater lagoon, which shifts through mesmerizing shades of turquoise and deep sapphire. Swimming here is not just a race; it is an immersion into a unique ecosystem characterized by its ancient stromatolites—living fossils that create a prehistoric, serene underwater landscape unlike anywhere else on earth.

Organized by a consortium of regional sports authorities and the local government, this annual event has become a cornerstone of the Mexican open water swimming calendar. The race attracts a diverse field of participants, ranging from elite long-distance specialists to amateur enthusiasts drawn by the calm, current-free waters and the warm hospitality of the Bacalar community. The event is deeply family-friendly, fostering a festive atmosphere that celebrates both athletic achievement and the preservation of the delicate local environment.

Beyond the competition, the town of Bacalar itself, with its rich history of pirate legends and colonial-era forts, provides a captivating backdrop for a weekend getaway. Whether you are traveling solo, with a training group, or with your family, the event offers the perfect excuse to {{link:accommodations|find a peaceful retreat}} by the water's edge.

Joining this marathon means becoming part of a tradition that honors the endurance of the athlete and the timeless beauty of the Mexican Caribbean's hidden jewel.
