Chad le Clos is a young man in a hurry. But he learnt that patience pays off in the sweetest way last night when the 21-year-old South African broke the world (short-course) 200 metres butterfly record at the Fina World Cup meet.
He had missed it last month in Dubai, when he came as close as 0.03 of a second, and at the following leg of the series in Doha.
So he tweaked his strategy, he assessed his splits, and he fine-tuned his training - for Tuesday's swim at the Singapore Sports School.
At the same pool where he launched his international career three years ago at the Youth Olympic Games, he timed 1min 48.56sec for the second world record of his career.
He said: "Of course I picked this one. This pool is where it all began for me - a few years ago, at the YOG, my first gold medal, my first national anthem ever.
"This is my second world record, very happy to be here... I love Singapore."
Erasing his own mark of 1:49.04 timed in August, le Clos became the third swimmer to set an individual world record in the series here.
American Natalie Coughlin rewrote the 100m backstroke mark in 2007, the year the annual eight-legged meet was first hosted here, and her compatriot Peter Marshall broke the 50m back mark in 2009.
Le Clos blew the field apart on Tuesday as he touched home over four seconds ahead of second-placed Pawel Korzeniowski of Poland (1:53.59) and Yuki Kobori (1:55.39) of Japan, who was third.
But the record and victory did not come easy. It took a courageous swim - bursting ahead from the start - coupled with a spellbinding finish.
