United States' Michael Phelps swims to win gold and set new world record in men's 200-meter butterfly final, 12 Aug 2008

But what stood out Wednesday was the victory by American great Michael Phelps in the men's 200-meter butterfly. That win gave Phelps his fourth title of the games and a record 10th career gold medal. He says every win has been special.

"When you have an Olympic gold medal, it stays with you forever," Phelps said. "That never leaves your side. You are always an Olympic gold medalist. Birthdays happen every year. Christmas happens every year. You know, you only get to be an Olympic gold medalist so many times."

Phelps added a fifth gold thanks to a record shattering performance in the 4x200 meter freestyle relay. He and three teammates clocked the first sub-seven minute performance ever (6:58.56), chopping more than four and a half seconds off the previous best. Phelps has three races remaining on Friday, Saturday and Sunday.

Stephanie Rice poses with her gold medal after the women's 200m individual medley medal ceremony in Beijing, 13 Aug 2008

The top accolade in the women's 200-meter individual medley went Australian Stephanie Rice, whose world record of 2:08.45 minutes edged Kirsty Coventry of Zimbabwe.

"The last 50 [meter] was a great challenge," Rice said. "I mean, we were both battling it out. And that is sort of what the Olympics is all about. It is about the challenge. I was trying not to look over because I knew she was right there. I just tried to close my eyes and concentrate on all the hard [practice] sessions we have done. And really just focus on my own race."

Italian Federica Pellegrini expressed her relief after lowering her own world record with a time of 1:54.82 minutes to win the women's 200-meter freestyle race.

"When I win, I say 'finally, finally.' Because this 200 meters [race], really I have been expecting to win this competition for the last four years. So for me, this is like I redeem myself," Pellegrini said.

American gold came on the Beijing streets, where Kristin Armstrong rolled to victory in the women's road-cycling individual time trial. Fabien Cancellara of Switzerland won the men's event.
