Today’s swimming training for the triathlon has been cancelled because of pollution in the River Seine.

Paris 2024 and World Triathlon have released a joint statement that explains that tests have shown the water quality of the river to be below an acceptable standard.

“The priority is the health of the athletes,” read the statement. “The tests carried out in the Seine [on Saturday] 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.

“Given the weather forecast for the next 48 hours, Paris 2024 and World Triathlon are confident that water quality will return to below limits before the start for of the triathlon competitions [on 30 July].”
