SINGAPORE- Darren Lim was trying to remain unnoticed in the middle of his swimming training two years ago.
Tired of the monotony of repetitive swim sets, the self-confessed "slacker" was constantly devising ways to skive.
Then aged 13, he would stop in the middle of a lap and quietly slip underwater to waited for his swim-mates to rejoin him.
However, his antics at Swimfast Aquatic Club did not escape his coach Gary Tan, who recalled: "He was really naughty and always playing around.
"It was really driving me crazy. His team-mates would also complain to me as they would also get affected when he was cheating during the sets."
Everything changed at Christmas 2011, when Tan and his assistant coach Richard Chng sat Darren down one evening after training to set him straight.
Said Tan: "It was Christmas, but I was stern. I told him to get his act together, I told him that he was driving me crazy."
Darren has an older sister, Shana Lim, who holds the national 50m backstroke record, and Tan used that as a motivational tool.
"I asked him to not live in Shana's shadow, to come out of his shell and not just be known as Shana's brother," the coach said.
