The open-water event is slated to the 2008 Olympic Games for the first time. It is also referred to as a "wrestling match in water" due to the aggressive techniques employed in competing in the sport. Competitors often knock into each other as they fight for position around the marker buoys and at the feeding stations.

"Ten kilometers is a long distance and there are a lot of girls in quite a short distance and in a short space. At the start, you have clashes on and when you are swimming you knock on each other. That does happen, that is the hard part of the race," Patten said.

Ilchenko also complained about the clashes in the race. "It's difficult. I myself had to clash on numerous occasions, especially with the swimmers from Brazil. The last stretch was particularly difficult. I had to via away all the time."

Ilchenko was given a yellow card warning during the race. But she said she didn't know it. "I didn't see I was given a yellow card. Perhaps at the time when I was trying to break away from the two Brazilian swimmers who were quite aggressive, sometimes bordering on being unsportsmanlike. This is swimming after all, not boxing."

The combative and aggressive nature of the open water event has failed quite some superfish in the pool. Australia's "long distance king" Grant Hackett was disqualified when trying to get a berth in the race in Beijing at the 2008 World Championships.

"Even if you are a super star, it doesn't mean anything when it comes to open water," Ilchenko said.

South Africa's Natalie du Toit, the first amputee qualified to swim the 10km open water race at the Olympics, ranked 16th.

"For me this is dream come true. I think I'm a bit upset as I wanted to come in the top five. But I even couldn't get out of the water at the finish, so I've done everything I possible could. I'm glad it's over," she said.

"Hopefully I'll be back for 2012 (London Olympics), where I'll be hoping for a top five place," she said.
