SINGAPORE – The start of the open water swimming competition at the World Aquatics Championships has been postponed by a day due to concerns over water quality off Sentosa, the organisers announced early on July 15.

The women’s 10km race, which was scheduled to kick off the open water programme on July 15 morning, will now be held on July 16. A total of 69 athletes had been expected to compete in the first event of the competition.

The men’s 10km race, initially planned for July 16, will still take place on the same day – before the women’s event. The remaining events – the men’s and women’s 5km (July 18), 3km knockout sprint (July 19), and the mixed 4x1,500m relay (July 20) – are set to proceed as scheduled.

In a statement, World Aquatics said: “While testing in recent days has consistently shown water quality at the venue to meet World Aquatics’ acceptable thresholds, analysis of samples taken on 13 July surpassed these thresholds.”
