​Footage from Sunday, July 12, 2026, captures hundreds of swimmers leaping into the Seine near the Eiffel Tower, then weaving past some of Paris’s most iconic landmarks. As the competitors raced downstream, cheering crowds lined the riverbanks to show their support, amplifying the excitement of this urban open-water event. At the finish, many athletes crossed the line with arms aloft, proudly accepting medals after completing the open-water race in the heart of Paris.
The Open Swim Harmonie Mutuelle represented the first organized swimming competition in the Seine in nearly 80 years. The event featured a flagship 8.5-kilometer course that stretched from the Bibliothèque nationale de France to Quai de Grenelle, complemented by shorter one- and two-kilometer distances to suit swimmers of all levels. Co-organizer and OlympicMedalist Stéphane Caron noted that the river’s water quality now meets exceptionally high standards, underscoring the event’s commitment to safety and sustainability.
Established in 2012 by a group of former French swimmers, including Caron, the Open Swim Harmonie Mutuelle has enjoyed 11 years of support from insurer Harmonie Mutuelle. In previous years, similar festivities took place on the nearby Canal de l’Ourcq, where 500-meter and five-kilometer races formed part of the same weekend program. The Seine edition signaled a milestone in Parisian open-water swimming, drawing participants and spectators to the city’s iconic shores and showcasing Paris as a premier destination for urban endurance events.
