Olympic triathlon goes ahead after officials give the green light over Seine water quality
More rain came into Paris overnight but World Triathlon and Paris 2024 determined the water quality was sufficient to move ahead for both the women’s and men’s races.
“Following a meeting on water quality held on 31 July at 3:30 a.m. attended by Paris 2024, representatives of World Triathlon and their Technical and Medical Delegates, Météo France, the City of Paris and the Prefecture of the Île-de-France Region involved in carrying out water quality tests, the stakeholders involved have confirmed that the women’s and the men’s triathlons will go ahead as planned on 31 July at 8 a.m. and 10:45 a.m. respectively,” Paris 2024 and World Triathlon said in a joint statement.
The women’s race had been marked by bike crashes on the wet streets of Paris. In the cycling portion of the race, several athletes fell after slipping on the slippery roads. Vittoria Lopes of Brazil was among the leaders when she fell but fell out of contention.
France’s Cassandre Beaugrand eventually was crowned women’s triathlon Olympic champion on home soil, roared across the finish line by a boisterous French crowd that broke out into a rendition ‘La Marseillaise.’
The men’s race is set to begin at 4:45 a.m. ET.
Rains impacting water quality
Heavy rains battered Paris over the weekend, drenching Friday’s opening ceremony and raising concerns about water quality in the river, which usually declines after rainfall.
Training was canceled for a second straight day on Monday after water quality testing deemed the water unsafe for athletes, but organizers were confident at the time that Tuesday’s race would go ahead as planned.
The decision to hold some swimming events in the famous river that splits Paris raised eyebrows when it was first announced. Swimming in the Seine has been illegal for a century but, in their desire to put the host city on full display, organizers worked up a plan to clean up the river so the world’s best athletes could use it during Paris 2024.
About $1.5 billion (1.4 billion Euros) has been spent trying to clean up the river ahead of the Games and Paris officials have made a big show of displaying its suitability. Paris Mayor Anne Hidalgo swam in the river earlier this month to display her confidence in the river’s water quality and promised to put a swimming pool in the river after the Games. The French sports minister has also gone for a dip in the Seine.
One of the key infrastructure projects designed to help tackle pollution has been a new rainwater storage basin – called the Austerlitz basin – which can hold 20 Olympic swimming pools worth of water, according to a statement from Paris 2024.
Following rainy weather on June 17 and 18, the basin filled to 80% capacity, successfully preventing 40,000 cubic meters (40 million liters) of wastewater and rainwater from being discharged into the Seine, according to the city of Paris.
But the water quality can change fast. Official data shows one-off rainfall events can quickly cause E. coli levels to spike again, and as recently as June 30 – following rain the previous day – E. coli levels increased to around 2000 CFU/100mL at Alexandra III Bridge, where the race is set to begin.
That’s double the level needed for “good” water quality, as per World Triathlon standards.
For much of the month before the games, E. coli levels were above acceptable levels, which could expose athletes to serious health concerns. If E. Coli levels are above 1000 CFU/100mL, the swimming leg of the triathlon will have to be cancelled, according to World Triathlon competition rules, unless the organization’s medical committee decides the race can go ahead.
The individual triathlon races begin with a 1.5-kilometer swim, followed by a 40K bike race – passing by the Le Grand Palais and the Champs-Élysées – before finishing with a 10K run through the heart of the city.
A mixed team relay race involving four athletes – two men and two women – will start with each team member completing a 300-meter swim, followed by a 5.8K bike ride and 1.8K run.
