On August 5, day nine of the London Olympics, all eyes will be pinned on the Games' most-expected athletic event, the men's 100-meter final, where Jamaica's Usain Bolt will have to prove he is still the fastest man on the planet.
Bolt, who won three Olympic golds in 2008, was beaten twice by fellow Jamaican Yohan Blake in national races last month.
In the fight for the Olympic tennis gold, Brit Andy Murray takes on Roger Federer, in a replay of this year's Wimbledon final, in which the Swiss legend prevailed.
Other events include men's and women's artistic gymnastics, men's weight lifting and Greco-Roman wrestling, and men's handball, where Serbia faces off with Hungary and Croatia -- the tournament's revelation so far -- takes on Spain.
Croatia, a double Olympic champion, has made lightwork of its group adversaries so far, crushing reigning European champions Denmark 32-21 on August 4, dismissing South Korea by 10 points, Euro 2012 runners-up Serbia by eight and Hungary by seven.
On August 4, day eight, U.S. swimmer Michael Phelps made Olympic history, ending his career with another gold medal as the United States won the medley relay.
The most decorated Olympian of all time leaves the sport with 22 Olympic medals, including 18 golds.
Speaking at a news conference, the American champion said, "I was able to really put the final cherry on top tonight, put all the whipped cream I wanted, and sprinkles. I was able to top off the sundae."
