All about the athletes swimming in the Seine at the 2024 Summer Olympics

On Wednesday, July 31, 2024, the men's and women’s triathlon swimming portion took place in the Seine River. In it, the athletes swam 1.5 km (0.93 miles) in the river before biking 40 km (25 miles) and then running 10km (6.2 miles).  

The women competed at 2:00 a.m. EST (8:00 a.m. Paris time), with the men following them at 4:45 a.m. EST (10:45 a.m. Paris time). This comes after a previous delay in the men's competition, causing the event to be moved from Tuesday, July 30 to Wednesday, July 31.

A press release by the Paris Olympic Committee detailed how they came to the decision to allow athletes to compete in the river for the swimming leg, saying: “Following a meeting on water quality held on 31 July at 3.30 am 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 ?le-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.”   

The World Triathlon also took to X (formerly known as Twitter) posting the words, “We will swim” at 10:13 p.m. on Tuesday, July 30, 2024.

Olympic athletes respond to swimming in the Seine  

Taylor Spivy, a United States competitor in the women’s division who came in 10th, told NBC News, “That current — wow. I felt like I was on a treadmill in one place.”  

She also told the news outlet that she has ingested “a ton of water” but prepared for that by taking a lot of probiotics due to the health concerns and heavy rainfall that hit Paris early in the week.  

Says Spivy: “We’ll see how it goes.”  

Jamie Riddle, a South African who competed in the men's competition,  echoed similar thoughts, revealing that, “I’m definitely going to be visiting the bathroom later, I swallowed gallons and gallons of water, so that’s gonna be a fun post-race party.”

Beaugrand came in first place in the women’s triathlon, finishing in 1:54:55. In second was Switzerland's Julie Derron, with Great Britain's Beth Potter rounding out the podium. One American — Spivey — placed in the top 10.
