Cassandre Beaugrand of France triumphed in the women's triathlon at the Paris 2024 Olympics, marking a successful first Olympic event held in the Seine River despite prior concerns over water quality. The race was initially postponed due to heavy rains that raised E.Coli levels, leading to doubts about the river's safety for swimming, but a last-minute test confirmed it was suitable for competition. Beaugrand's victory came after a tightly contested finish against Switzerland's Julie Derron and Britain's Beth Potter, taking gold in a time of 1:54:55. The men's triathlon, which was scheduled for Tuesday, was rescheduled to follow the women's event due to the same water quality issues. President Emmanuel Macron celebrated the achievement, highlighting the significant investment of 1.4 billion euros to modernize Paris's sewage system. Despite challenging conditions, including slippery roads and strong currents, the event drew a supportive crowd cheering on the athletes.
