The Belgian triathlon mixed relay team withdrew from the event at the Paris Olympics after one of its athletes, Claire Michel, fell ill following her swim in the Seine River.
Michel, who competed in the women's triathlon last Wednesday, was taken to a clinic in the Olympic Village on Sunday for treatment, as reported by The New York Times.

Claire Michel, 35, finished in 38th place in the women's triathlon and later experienced health issues. The Belgian Hammers, as the team is known, announced that Michel had been treated and had returned to her room by Sunday evening.
The statement, released by Belgium's Olympic committee and triathlon federation, did not specify whether Michel's illness was directly caused by pollution in the Seine. However, in the days leading up to her race, there were significant concerns about the river's water quality.
The men's individual triathlon event had been postponed, and training sessions were cancelled due to unsafe swimming conditions detected through water quality testing. Despite these precautions, Michel competed in the women's event, and the team's subsequent withdrawal highlights the ongoing issues related to the Seine's pollution.
The Belgian Olympic Committee and the Belgian Triathlon Federation expressed their hope that future triathlon competitions will learn from this experience. They emphasized the need for guaranteed training days, clear competition formats, and conditions that do not create uncertainty for athletes, their entourages, and fans.
Concerns about the Seine's water quality have overshadowed the Paris Olympics. Prior to the Games, more than $1.5 billion was invested to ensure the river was safe for athletes.
However, heavy downpours during the opening weekend of the Olympics are equivalent to a month's worth of rainfall in just 36 hours to a spike in dangerous bacteria levels in the river. These bacteria levels can take one to three days to subside, complicating the situation further.
Daily water quality tests are being conducted by Games officials to monitor the safety of the Seine. Last week, training sessions were cancelled for two consecutive days, and the men's triathlon was delayed by a day due to high bacteria levels. These disruptions underscore the challenges faced by the organizers in ensuring the safety of the athletes competing in open-water events.
The withdrawal of the Belgian triathlon team is a significant development, reflecting broader concerns about the environmental conditions at the Paris Olympics. As the Games continue, the focus remains on ensuring that all events are conducted in safe and healthy conditions for all participants.
