Paris 2024 Olympics triathlon organizers have canceled training sessions for the swimming leg for the second consecutive day on Monday due to elevated pollution levels in the Seine river. Despite this setback, Paris 2024 and World Triathlon remain confident that the medal events will proceed as planned later in the week.

The decision to cancel the triathlon training was made in consideration of the athletes' health, with heavy rainfall on July 26 and 27 exacerbating the pollution levels in the Seine river. The pollution, including high E.coli bacteria levels, has prompted concerns regarding the safety of the water for triathlon and marathon swimming events.

France has invested over $1.5 billion in efforts to ensure the Seine is suitable for the Olympic events. The men's individual triathlon is scheduled to kick off on Tuesday at 8:00 a.m. local time, followed by the women's individual event on Wednesday.

Options for the organizers include potentially delaying the swimming events by a day or relocating the marathon swimming to a river east of Paris as a last resort. Efforts to maintain water quality continue as various vessels and watercraft were observed on the Seine river on Monday, with individuals conducting tests by collecting water samples.

As the Paris 2024 Olympics prepare to showcase the world's athletic talents, challenges such as the Seine river pollution highlight the complex logistics involved in hosting a successful international sporting event. The determination to prioritize the athletes' well-being while striving for the smooth operation of the Games remains at the forefront of the organizers' decision-making process.
