Milorad Čavić

At the age of 16, Čavić represented Yugoslavia at the 2000 Summer Olympics in Sydney, Australia in the 100 m butterfly (disqualified) and 100 backstroke – 42nd – 58.25 s.[9]

Čavić represented Serbia and Montenegro at the 2004 Summer Olympics in Athens, Greece in the 100 m butterfly, 50 m freestyle and the 100 m freestyle.

Čavić was leading in a semifinal of the 100 metre butterfly, but right after the turn at the halfway point of the race, his suit opened at the neck and sucked in water, causing Čavić to finish last. In the heats of the 100 metre freestyle, Čavić finished 19th missing the semi-finals by 0.02 seconds.

Čavić trained at The Race Club, a swimming club founded by Olympic swimmers Gary Hall, Jr. and his father, Gary Hall, Sr. The Race Club, originally known as "The World Team," was designed to serve as a training group for elite swimmers across the world in preparation for the 2000 Sydney Olympics. To be able to train with the Race Club, one must either have been ranked in the top 20 in the world the past 3 calendar years or top 3 in their nation in the past year. The Race Club included such well known swimmers as Roland Mark Schoeman, Mark Foster, Ryk Neethling, Ricky Busquet and Therese Alshammar.[10] The Race Club offers various swimming camps, swim clinics, and swimming technique video recording year round for young swimmers at their Islamorada, Florida based training center.[11]

Čavić represented Serbia at the 2008 Summer Olympics in Beijing, People's Republic of China in two swimming events. Even though he qualified for the 100 metre freestyle semi-final Čavić withdrew in order to prepare for the 100 metre butterfly.

On August 14, 2008 at the Beijing Olympics, Čavić broke the 100 meter butterfly Olympic Record during the preliminary heats, finishing ahead of Michael Phelps and also recorded the fastest time in the semi-finals. Čavić came in second to Phelps by one hundredth of a second in the final, and became Serbia's inaugural Olympiad medalist. It was Phelps' seventh gold medal of the Olympiad. The Serbian team initially challenged the result but FINA later confirmed the finish. It was later confirmed by the FINA and Omega timekeeping officials that Čavić indeed arrived firsts but it was Phelps who, in the milliseconds after touching the wall, applied more force to trigger an electronic touchpad first.[12] Čavić later wrote in his blog: "People, this is the greatest moment of my life. If you ask me, it should be accepted and we should move on. I’ve accepted defeat, and there’s nothing wrong with losing to the greatest swimmer there has ever been".[13]

Čavić continued training at The Race Club.[10]

Čavić represented Serbia at the 2012 Summer Olympics in London, England, making it his sporting finale. He qualified for the 100 meter butterfly final and tied for fourth place.
