The test run to allow Olympic athletes to familiarise themselves with the marathon swimming course in the Seine has gone ahead.
World Aquatics cancelled a familiarisation session 24 hours earlier as water quality assessments found levels of Enterococci - an indicator of faecal pollution - were too high in the river.
Fluctuating bacteria levels in the long-polluted waterway have been a constant concern throughout the Games.
But World Aquatics, Paris 2024 and other officials met Wednesday morning and concluded the latest water test results were acceptable.
The women's marathon swim competition is set for Thursday, while the men are scheduled to race Friday.
The triathlon mixed relay event was held Monday in the river and World Triathlon released data Tuesday showing the levels of fecal bacteria E. coli and enterococci were within acceptable levels during those swims.
The marathon swims take place on longer portions of the river and will start and finish at the Pont Alexandre III. Marathon swimmers do six laps on the 1.67km course for a total of 10km.
Organisers said they “remain confident” that the marathon swimming events will happen in the Seine as planned based on “a favourable weather forecast and forward-looking analysis.”
Meanwhile, Belgian triathlete Claire Michel who fell ill and caused her team to withdraw from the mixed relay event at the Paris Olympics, said blood tests showed it was a virus that had made her sick.
Michel had competed a few days earlier in the women’s triathlon, which included a swim in the Seine.
Some news outlets had reported Michel had been sickened by E. coli and spent several days in the hospital.
In an Instagram post, she wrote there had been “a lot of conflicting information in the media lately” and she wanted to “clarify a few things.”
It was not E. coli that made her sick, she wrote, adding she sought treatment at a clinic in the Olympic village on Sunday after several days of vomiting and diarrhoea “left me quite empty.”
