- Chad Le Clos shot to fame after beating Michael Phelps at the 2012 Olympics
- The South African swimmer wants to go even further at this year's Commonwealth Games
- For le Clos, it's a test of the mind as well as the body
(CNN)South African swimmer Chad Le Clos is out to make history.
The 25-year-old, a multiple world champion and 2012 Olympic gold medalist, is hoping to become the most successful athlete in the history of the Commonwealth Games.
Le Clos is six medals away from his goal. Ahead of the 2018 Commonwealth Games on Australia's Gold Coast, two shooters -- Englishman Mick Gault and Australian Philip Adams -- lead the way with 18 medals.
The pair amassed their totals over six Games. Le Clos aims to do it in just three.
In it to win it
At the 2014 Commonwealth Games, Le Clos medalled in all seven of the events he entered -- including gold in the 100m and 200m butterfly -- bringing his medal total to 12.
This year, Le Clos is chasing podium finishes in all three butterfly events -- he is a former world champion over 50m and the world record holder over 100 and 200m -- as well as a top-three finish in the 200m freestyle.
He is also hoping for two relay gold medals, though this task has been more difficult following a row over South Africa's selection policy for the Games.
Backstroke swimmer Christopher Reid and Zane Waddell, who competes in freestyle, were left out of the team after they were unable to attend mandatory South African trials in December due to study commitments in the US.
Despite this setback, Le Clos is determined.
"I just love to win," he tells CNN, "I love to compete at the highest level and I really enjoy racing."
It was the 2012 London Olympics when Le Clos shot to global fame. Aged 20 at the time, he was placed in the lane next to his idol, swimming legend Michael Phelps, for the 200m butterfly final.
In the race's early stages everything had been going to plan for Phelps, the most decorated Olympian of all time. But over the final 50m, Le Clos chased him down and took gold by a fingertip margin of 0.05 seconds -- ending the American's domination of the event since the 2004 Games.
Le Clos became an instant hero -- as did his father Bert, whose ecstatic and breathless reaction in a subsequent TV interview went viral.
Bert Le Clos is not just his son's most enthusiastic fan but also the driving force behind his swimming career, convincing him to give up football -- which he also played at a national level until about 13 years old -- and focus on the pool.
It proved the right decision. By the age of 14, Le Clos had made the senior Olympic squad, and by 18 he held two South African records. He is now his country's most-decorated Olympian.
Getting to such an elite level requires more than physical strength. As Le Clos readies himself for the start of the Commonwealth Games on April 5, there will be long hours in the pool and the gym, but also "a lot of mental, emotional and psychological preparation."
"My biggest attribute is my mind," he explains, "and my willpower to try to be the best that I can be."
