The men’s triathlon at the Olympics has been postponed due to polluted water in the Seine River, with last-minute tests revealing water quality levels that were “still above the acceptable limits” for Tuesday’s race to go ahead on time and leaving athletes facing uncertainty.

Heavy rain led to increased levels of the harmful bacteria E.coli in the Seine, despite more than €1bn spent in an ambitious plan to clean up the river and host open-water swimming events in the Seine. Organisers had previously said they were confident the race would go ahead on time.

Swimming training event for the triathlon had been cancelled for two consecutive days on Sunday and Monday because of concerns over water quality and organisers now plan to stage both men’s and women’s races on Wednesday morning, but that remains contingent on water levels improving.

“Following a meeting on water quality held on 30 July at 3.30am attended by Paris 2024, representatives of World Triathlon and their Technical and Medical Delegates, the International Olympic Committee, Météo France, the City of Paris and the Prefecture of the ile-de-France Region involved in carrying out water quality tests, a decision has been made to postpone the men’s triathlon event which was due to be held on 30 July at 8am.

“Considering the latest weather information, it has been decided to schedule the men’s triathlon event on 31 July at 10h45. The women’s triathlon is due to take place the same day at 8am. Both triathlons are subject to the forthcoming water tests complying with the established World Triathlon thresholds for swimming. The original contingency day also remains in place for August 2, for further considerations.

“Paris 2024 and World Triathlon reiterate that their priority is the health of the athletes. The tests carried out in the Seine today revealed water quality levels that did not provide sufficient guarantees to allow the event to be held.

“Unfortunately, meteorological events beyond our control, such as the rain which fell over Paris on 26 and 27 July, can alter water quality and compel us to reschedule the event for health reasons. Despite the improvement on the water quality levels in the last hours, the readings at some points of the swim course are still above the acceptable limits.

“We will provide the athletes who are due to take part in the men’s triathlon event with all information on its postponement, as well as real-time updates on the situation. Information regarding tickets and broadcast of the events on Wednesday July 31 will be shared in the next hours. There will be a meeting at 8am between World Triathlon and the coaches to provide further information and the updated schedule for July 31.”

Tom Daley gazed up after completing the set of Olympic medals with a fabulous silver alongside Noah Williams in the men’s synchronised 10m platform. But then came a surprise; a juice cup launched from above in his direction. It was his adorable son Phoenix, revelling in his father’s latest glorious Olympic moment, tossing down his cup in pure excitement as reporters scattered.

Three hundred and twenty-eight other gold medals will be handed out at these Paris Games, but surely none will be won as dramatically as this. Tom Pidcock lost the race to a puncture, won it back, then lost it again to the determined Frenchman Victor Koretzky before pulling off a do-or-die overtake around a tree to defend his Olympic title.

Hollie Pearne-Webb insists Team GB’s women’s hockey stars will use their turbulent Tokyo experience to help them bounce back and ‘create history’ after a slow start at the Olympics.
