Olympic men's triathlon postponed due to Seine pollution concerns

The big picture: Results of tests undertaken July 17-23 indicated levels of E. coli and other potentially harmful bacteria had risen at points of the river where athletes were due to compete following heavy rains, per an Olympics report.

• Officials canceled training in the Seine over the weekend "after revealed water quality levels that in the view of the international federation, World Triathlon, did not provide sufficient guarantees to allow the event to be held," per an emailed statement from Olympics organizers Monday.
• The statement expressed confidence from the 36-hour weather forecast that water quality would improve enough to hold the men's event on Tuesday morning as scheduled.

Driving the news: "Despite the improvement on the water quality levels in the last hours, the readings at some points of the swim course are above acceptable levels," per the statement that World Triathlon posted to X that was also shared by Paris 2024 organizers that cited heavy rainfall in Paris last Friday and Saturday.

• "Paris 2024 and World Triathlon reiterate that their priority is the health of the athletes."

What we're watching: Olympic officials rescheduled the men's triathlon event to 10:45am Wednesday local time following the women's competition that's due to take place at 8am that day after taking into consideration the latest weather forecast, according to the statement.

• "Both triathlons are subject to the forthcoming water tests complying with the established World Triathlon thresholds for swimming," per the statement.
• A "contingency" plan remains in place to hold the event on Friday if needed.
