Paris 2024 organisers cancelled training for open-water swimming on Tuesday because of pollution in the River Seine.
The latest cancellation happened a day after the mixed team triathlon relay was held.
The cancellation makes it the fifth time the water quality has forced a swim familiarisation session to be cancelled during these Games. The men’s race also had to be put back a day.
All the triathlon swim legs have taken place in the Seine, which is also set to be used for marathon swimming.
Tests taken showed the levels of the enterococci bacteria in the water had dropped back below the required standard, although E. coli levels were still deemed acceptable.
Another familiarisation session was scheduled for Wednesday, with the women’s 10km race due to take place on Thursday and the men’s race on Friday.
Paris 2024 spokesperson Anne Descamps said, “We are confident the events will go ahead as planned given the weather tendency.”
Heavy rainfall has increased the levels of bacteria in the Seine, although hot weather helps to reduce the count.
Organisers have disclosed that If the Seine is still deemed unsuitable, the marathon swimming can be moved to Vaires-sur-Marne, east of Paris, where the rowing and canoeing competitions take place.
