Paris 2024 organisers are confident the Olympic triathlon events will go ahead as scheduled from Tuesday despite concerns over pollution in the River Seine.
Two swimming training sessions were cancelled on Sunday and Monday because of the water quality.
There was heavy rain in Paris last week, which has affected the water quality, and temperatures are now expected to reach 34C on Tuesday, when the men’s event is scheduled to start.
The men’s event is due to take place at 1 am Jamaica time, with a final decision to be made today at 9pm.
The women’s event is set to take place on Wednesday and the mixed team competition on August 5.
