Open Swim Paris, an annual event set to occur in the Seine River, was called off because of inclement weather in the French capital. The river was made accessible to both local residents and tourists on the succeeding day.
France24 had a conversation with Stephan Caron, one of the co-organisers of Open Swim Paris 2025.
