James Magnussen, known as "The Missile," has had a storied career in competitive swimming. Born and raised in Sydney, NSW, Australia, Magnussen began swimming at the age of three. By 11, he was competing in the sport, driven by his parents' desire for him to learn water safety due to their proximity to the beach.

Despite his successes, Magnussen faced significant challenges. In August 2014, he suffered a back injury that affected his performance for two months. In June 2015, he underwent shoulder surgery, which ruled him out of competing at the World Championships in Kazan, Russia.
In June 2019, Magnussen announced his retirement from competitive swimming at the age of 28. He cited difficulties in maintaining his love for the sport due to physical challenges. "I believe now is the right time to step away from the sport," he said.
Outside of swimming, Magnussen enjoys going to the beach and spending time with friends. He holds a degree in Sports Management from the Australian College of Physical Education in Sydney. His sporting philosophy is simple: "There is nothing to it but to do it."
Magnussen has several tattoos that hold personal significance. After returning from the 2011 World Championships, he got an alpha symbol tattooed on his left forearm as a reminder of overcoming early challenges. He also has the Olympic rings tattooed on his ribs.
