The athlete training session for the Olympic marathon swimming was cancelled on Tuesday as concerns over the water quality of the River Seine continued at Paris 2024. Ireland's Daniel Wiffen, already a double medal winner in the pool, is due to take part in the event. 

Athletes had been due to take to the water for familiarisation sessions ahead of the women's 10 kilometre marathon on Thursday and the men's race on Friday, but water quality assessments found that levels of Enterococci - an indicator of faecal pollution - were too high in the river.
