Today's Birthday, June 25: Australian swimmer and Olympian Kyle Chalmers (1998 - )

Olympic gold medallist Kyle Chalmers blazed through this month's world championship trials with the fastest 100m freestyle of the year.

The 20-year-old swam a personal best of 47.35 seconds but wants to go even faster to beat reigning world champion Caeleb Dressel of the US.

"I need to work on my speed if I'm going to take on Dressel," he told The Courier Mail.

Chalmers was born in Port Lincoln, South Australia, in 1998 and attended Immanuel College. His father is former AFL and Port Adelaide premiership player Brett Chalmers.

In 2018 Chalmers admitted he'd dreamed of playing AFL since childhood but he was not ready to walk away for swimming yet.

"I'll swim now for as long as I can and look to play country footy one day," he told the Sydney Morning Herald.

Chalmers holds the junior world record in the 100 metre freestyle and won the gold medal in the same event at the 2016 Olympics. He also won the gold medal for the men's 200 metre freestyle at the 2018 Gold Coast Commonwealth Games.

In 2017 Chalmers was forced to withdraw from the world championships after he had successful surgery for the heart condition known as supraventricular tachycardia.

In 2016 he won the Australian Institute of Sport Performance Awards' Male Athlete of the Year and Best Sporting Moment. The same year he also received South Australian Sports Star of the Year and Swimming Australia Awards' Olympic Swimmer of the Year and Golden Moment. Last year he was crowned Oceania Male Swimmer of the Year.

Chalmers is also a reptile enthusiast and runs an Instagram account dedicated to his passion, boasting more than 11,000 followers.

"I probably pushed everything aside and thought swimming was me after the Olympics, and now I'm trying to re-find all those loves that I had and that helped me perform, like I'm obsessed with reptiles," he told The Australian.

"Blue tongue skinks are my thing, I've got about 16 of them. I've got all the super-rare ones, albinos, I'm right into it."
