Olympic triathletes took to the Seine River in Paris on Wednesday, overcoming previous water quality concerns that had delayed events. After a $1.5 billion cleanup effort, officials declared the water safe for the women's and men's triathlon events, allowing France's Cassandre Beaugrand and Great Britain's Alex Yee to win gold medals. Despite ongoing rainfall that raised concerns about water pollution, the competitions proceeded near the iconic Pont Alexandre III. Organizers confirmed that water quality tests met the required standards, although heavy rainfall poses a risk of contamination. The successful swim marks a significant achievement for Paris 2024, which has invested heavily in infrastructure to improve the Seine's condition for the Olympics. Future marathon swimming events may be relocated if water quality issues recur.
