Men's Olympic Triathlon postponed due to Seine pollution levels

The men's triathlon at the Paris Olympics will be rescheduled to Wednesday due to high pollution levels in the Seine, as confirmed by World Triathlon.

The event will now take place at 10:45 (09:45 BST) following the women's race at 08:00 (07:00 BST) on the same day.

Despite expectations of improved water quality after recent heavy rains, some areas of the swim course still exceed safe limits. Organizers emphasize the health of the athletes as their top priority.

If pollution levels persist on Wednesday, both races may be postponed to Friday, the designated contingency day.

In the event of continued poor water quality, the swim portion will be replaced with a duathlon. The mixed triathlon relay event on August 5th has a contingency day on August 6th.

Authorities in Paris have committed to making the Seine River swimmable as a significant legacy of the Olympic Games, investing 1.4 billion euros (£1.17 billion) in wastewater infrastructure to manage sewage and reduce contamination in the waterway.

Earlier this month, Paris Mayor Anne Hidalgo personally swam in the river to reassure skeptics about its cleanliness.

The decision to rely on the river's water quality for the triathlon was a risky one, as the cleanliness of the water can fluctuate significantly from day to day.

Rainfall tends to elevate the levels of harmful bacteria, such as E. coli and enterococci, in the water.

Seth Rider, one of the 55 triathletes competing in the men's event, shared with reporters that he has taken unusual steps to prepare for potential bacterial exposure.

"We are aware that there will be some E. coli exposure, so I try to raise my E. coli tolerance by encountering a small amount of E. coli in my daily life," the American athlete stated during a press conference on Saturday.

The design of the Olympic triathlon course aims to create a spectacular experience, with the river swim being a central feature.

Athletes will leap into the Seine from a pontoon adjacent to the Alexandre III bridge, racing past the Musée d'Orsay and Grand Palais during the cycling and running segments before returning to their starting point.

As they cross the finish line on the bridge, competitors will be framed by stone columns adorned with gilt-bronze statues of Pegasus, with the golden dome of the early 18th-century Invalides monument serving as a stunning backdrop.
