The Paris 2024 Paralympic triathlon events originally rescheduled for September 1 were postponed by a day due to poor water quality in the River Seine following heavy rainfall. Organizers from World Triathlon and Paris 2024 stated that recent tests showed a significant drop in water quality, making it unsafe for athletes to swim. The events will now take place on September 2, pending further water quality tests. This postponement is part of ongoing challenges faced by the Paris Olympics and Paralympics, where several events were previously disrupted due to similar water quality issues caused by rain-induced pollution. Organizers emphasized that the health of the athletes remains their top priority.
