Pool love triangle reunion as Kyle Chalmers, Emma McKeon and Cody Simpson compete together this week

There’s a reunion of the so-called arctic love triangle between Emma McKeon, Cody Simpson and Kyle Chalmers, with the trio set to team up again this week at the Australian Short Course Championships in Sydney.

The tournament, where swimmers race in a 25m pool instead of a 50m pool, marks the first time since the Commonwealth Games that all three have been on a pool deck together.

Chalmers, who briefly dated McKeon last year, caused a storm of attention at the Games when he repeatedly came into contact with the media about coverage of his life, both in and out of the pool.

McKeon, the most decorated Olympian in Australia’s history, has since moved on with singer-swimmer Simpson – with the pair both taking part in the Duel in the Pool event last weekend.

Simpson and Chalmers will compete in two events in the national short course titles, which begin Wednesday: the 50m and 100m freestyle.

It’s another twist for Chalmers, who in May dismissed speculation that his sole reason for competing in the 100m butterfly was to ensure Simpson missed out on a spot on the World Championship team.

Simpson appeared to have secured a spot among the champions as he finished third in the National Titles event behind Chalmers and winner Matt Temple.

Australia was only able to send two representatives but Simpson was expected to make it as Chalmers would drop out due to his busy schedule and have to save his body after sustaining serious injuries.

But just two days later, the freestyle gold medalist backflips and decided to swim the 100m butterfly, leaving Simpson out in the cold.

After all that, Chalmers didn’t make it past the tournament semi-finals in Hungary, though he denied that the decision to backflip was a personal one.

“I think for me, I started with butterfly, I’ve wanted to be a butterfly all my career. My body just won’t allow me to do that, so being able to swim butterfly is so special to me,” he said. 2Day FM at the time.

“Unfortunately, yes, I’m the one who has to stand up and apologize and be called the bad guy for giving my all to my sport and my country.”

He is not a butterfly player in this tournament: the only stroke he will participate in is freestyle over 50, 100 and 200m.

Australian coach Rohan Taylor confirmed Chalmers will return to the pool from Wednesday and join an all-star team.

“When Melbourne got the world discount, it was amazing how many athletes went, ‘You know, I’m going to have a crack,'” Taylor told the Daily Telegram.

“I think there’s only a handful that don’t put themselves out there. For our best athletes to compete, Kyle (Chalmers) and others, I am a lucky coach with the best talent on my team.”

Simpson will literally spread his wings and compete in five major events, the 50 and 100 meter freestyle, 50 and 100 meter butterfly and the 100 meter individual medley.

McKeon, who first swam to Australia at the 2015 World Championships, will compete in the events where she won medals in Birmingham: the 50 and 100m freestyle and butterfly events.
