Potter continued Britain's dominance in the Series as the country has now won all four elite women's races, including her victory at Abu Dhabi in the opening race of the season.

The other winners were Sophie Coldwell in Yokohama and Georgia Taylor-Brown in the last event at Cagliari.

In this race, Potter clocked in after 58min 10sec as she outpaced Frenchwoman Leonie Periault on the final stretch to pip her to the win by two seconds.

"I didn't have a great swim today but I just made sure I stayed cool and calm and worked hard on the first two laps of the bike and got back on," the 31-year-old from Glasgow said.

"I wasn't actually sure where she [Periault] was and I was thinking if she's in front of me, I am in trouble.

"She was in front of me and I still managed to get there so that's a big confidence boost."

The United States' Summer Rappaport started brilliantly in the swim, leading both Potter and Periault, but was unable to maintain it and settled for bronze with a time of 58:19.

It was Rappaport's first World Championship Series medal podium since Hamburg in 2021.

"I am thrilled," Rappaport said.

"It’s been a really difficult couple of years, I thought about quitting probably more days than not but I think everybody likes seeing someone who is consistent, but I think sport is more about having the struggles and standing back up and keeping on fighting.

"I think that's why most athletes do it and I am not going to quit on myself because of hard times. 

"I was pretty proud of myself today."

In the men's event, Hauser finished on top of a 55-strong field at the Old Port after 53:47.

Brazilian Manoel Messias and Jelle Geens of Belgium followed him across the line 11 and 15 seconds later respectively, to round out the top three.

The victory pushes Hauser up to fifth place in the Series rankings.

"I've just been building my momentum," Hauser said.

"After Yokohama, where I finished in second place, I knew I had a better lead-up in prep.

"I felt good out there and got the job done.

"It's instinct, you've just got to act in the moment. 

"I knew the other guys were just settling into a rhythm and you can't let that happen.

"I knew the sooner I went, the better.

"I was lucky enough to break them up but it was a big group of guys on the run and it certainly wasn't wrapped up until the end."

A mixed relay event was also supposed to take place tomorrow but has had to be cancelled due to smog emanating from forest fires in Quebec.
