Le Clos stretched his lead to 92 points over Russian Vladimir Morozov at the last three meetings in Moscow, Dubai and Doha, over a 10-day period which ended on Monday.
Two other South Africans were also holding their own after five legs, with veteran sprinter Roland Schoeman lying sixth overall in the men’s series and rising distance star Myles Brown in seventh.
“It was a great week and I’m really happy,” Le Clos said yesterday. “Winning the overall cluster is obviously big for me but my coach (Graham Hill) and I are also trying to make sure I’m having good swims and good races, which is important.
“The SA team is doing well and we’re hoping to end the year on a positive note.” The last three meetings will be held in Singapore, Tokyo and Beijing between November 5 and 14, and Le Clos hopes to maintain his momentum in an effort to win the series for a second time.
“The World Cup has become really serious. “It’s a lot different to last year when you only really needed to win three big races to win the series. “Now you have to compete in every event and I’m having to swim just off my world record in every final.”
Le Clos broke the world 200m butterfly short course record when he touched the wall in 1:49.04 at the opening leg of the series in Eindhoven.
After missing out by 0.03 seconds at the fourth leg in Dubai last week, he hopes to have another crack at his own mark before the end of the campaign.
“It’s going to be hard to do it again. You can’t be on form every time you compete. “But I’ll try at the last leg in Beijing. I think that will be my best chance.”
