Rival and teammate Ryan Lochte might have other plans, though.
Usain Bolt

OLYMPIC EXPERIENCE: 2008 Beijing (3 Gold)
*All information courtesy of <a href="http://usainbolt.com/" target="_hplink">www.usainbolt.com</a>
Needless to say, all eyes will be on Usain Bolt when he steps on the track in London. Not just to see if he can duplicate a performance anything like what he did in 2008, but just to see the 6'5'' phenom and reigning world's fastest man compete on the world's biggest stage.

Abby Wambach, last year's AP Female Athlete of the Year, isn't just trying to lead the U.S. women's soccer team to another Olympic gold medal victory. She is looking to <a href="http://articles.latimes.com/2012/jul/19/sports/la-sp-oly-soccer-abby-wambach-20120720" target="_hplink">build on the momentum in popularity she and her teammates helped build for women's soccer in the United States. </a>

Not too long ago Roger Federer showed that he isn't done winning grand slams, <a href="http://www.huffingtonpost.com/2012/07/08/roger-federer-defeats-andy-murray-wimbledon-final_n_1657394.html" target="_hplink">defeating Andy Murray for his seventh Wimbledon title</a>. Well, he'll be playing on those same grass courts where he has been dominant at the London Olympics. With a gold medal in doubles in 2008, Federer will be going for his first Olympic gold medal in singles.

OLYMPIC EXPERIENCE: 2008 Beijing (Gold)
*All information courtesy of <a href="http://www.teamusa.org/Athletes/SO/Hope-Solo.aspx" target="_hplink">www.teamusa.org</a>
Although Hope raised eyebrows recently revealing her "Olympic secret" about partying in the village in 2008, the U.S. star goalkeeper seems poised to <a href="http://www.timesheraldonline.com/sports/ci_21127639/u-s-goalkeeper-hope-solo-ready-olympics" target="_hplink">lead her team to another gold medal without any distractions. </a>

*All information courtesy of <a href="http://www.teamusa.org/Athletes/LO/Ryan-Lochte.aspx" target="_hplink">www.teamusa.org</a>
One of the biggest challenges in Michael Phelps' path is teammate Ryan Lochte. Despite both representing the U.S., the pair has developed into a fierce rivalry with both getting the best of each other over the last few years. Lochte beat Phelps twice in the 2011 World Championships, but Phelps came out on top three out of four times at the Olympic trials. They're competing in two races against each other. It might be safe to say there will be plenty of viewers tuned in for those.

Nicknamed M'n'M, Matthews Mitcham is trying to repeat with an Olympic gold medal after becoming the first Australian to do so since 1924 when he received the highest single-dive score in Olympic history in Beijing. The 24-year-old <a href="http://www.huffingtonpost.com/2012/04/18/matthew-mitcham-gay-olympic-diving-champion_n_1435257.html" target="_hplink">openly gay diver</a> recently said that his mental toughness <a href="http://wwos.ninemsn.com.au/article.aspx?id=8503335" target="_hplink">"could make the difference"</a> in winning at the London Games.

He has already won <a href="http://www.london2012.com/athlete/wiggins-bradley-1093813/" target="_hplink">three other events in 2012</a> other than the Tour de France, making him one of the <a href="http://www.oddschecker.com/olympics/cycling/mens/time-trial/winner" target="_hplink">favorites </a>to bring home an Olympic gold medal.

Wu Peng didn't have the outcome he was looking for in 2008. Nobody did when Michael Phelps was in the pool. But in 2011 <a href="http://sportsillustrated.cnn.com/multimedia/photo_gallery/1107/olympics-2012-olympians-to-watch/content.46.html" target="_hplink">Peng took down Phelps twice in the 200 fly</a>, a race Phelps hadn't lost in nine years.

*All information courtesy of <a href="http://www.marielzagunis.com" target="_hplink">www.marielzagunis.com</a>
It may be tough to believe that fencing star Mariel Zagunis was <a href="http://usfencing.org/athletes/mariel-zagunis" target="_hplink">originally a replacement athlete for the 2004 U.S. Olympic Team.</a> When the women's saber event made its debut in 2004, Zagunis came home with the gold becoming the first U.S. fencer in 100 years to accomplish that feat. After winning the gold in Beijing, Zagunis will try to three-pete in London.

Lauren Jackson, a three-time WNBA MVP, will try to lead Australia to a gold medal after finishing with the silver in 2008. Knowing that this might be her last opportunity to win gold at age 31, Jackson skipped the first half of the 2012 WNBA season to prepare.
"The one thing I haven't done in my career is get a gold medal at the Olympic Games. It may be my last opportunity," <a href="http://www.perthnow.com.au/sport/2022-world-cup-bid/australian-wnba-star-lauren-jackson-sets-sights-on-london-olympics/story-e6frg25u-1226045580817" target="_hplink">she said back in 2011</a>.

The fastest man in the United States set quite a benchmark for the other sprinters in the Olympic 100 meters final, believing it will take 9.7 seconds <a href="http://www.chicagotribune.com/sports/olympics/sns-rt-us-oly-athl-atm100-mgay-adv8bre86i138-20120719,0,14372.story" target="_hplink">"to even get a medal"</a> (Usain Bolt was the first to ever crack 9.8). Gay edged Bolt in 2010, but hip surgery in 2011 kept him from running for almost a year. After Gay's comment praising the other runners like Bolt, Yohan Blake and Asafa Powell, the U.S. track star will look to be one of the men to beat 9.8.

Kohei Uchimura, 23, won the silver medal in the men's all-around gymnastics even in the 2008 Olympics.

Semenya, who was also <a href="http://www.guardian.co.uk/sport/2012/jul/19/london-2012-caster-semenya" target="_hplink">chosen to carry the South African flag</a> at the opening ceremonies, finished second (800m) in the 2011 World Championships but was <a href="http://sports.espn.go.com/oly/trackandfield/news/story?id=6626100" target="_hplink">struggling with injury. </a>

Kenenisa Bekele looks to continue his reign as the best long-distance runner in the world when he once again competes in the 5000- and 10,000-meter double. He did the same in 2008, winning both events and setting Olympic records in the process. The only thing that could stop him would be injuries which have slowed down the 30-year-old. But back in May, Bekele said he was<a href="http://www.telegraph.co.uk/sport/olympics/athletics/9257423/London-2012-Olympics-Ethiopian-Kenenisa-Bekele-is-free-of-injury-and-aiming-for-gold-in-both-5000-and-10000m.html" target="_hplink"> "free from injury</a>" and is aiming for gold.

Earlier this year, soccer legend Pele said Neymar is<a href="http://www.huffingtonpost.com/2012/04/11/pele-messi-surpass-neymar-best-soccer-video_n_1417118.html" target="_hplink"> better than three-time world player of the year Lionel Messi. </a><a href="http://espn.go.com/sportsnation/post/_/id/7801054/neymar-lionel-messi" target="_hplink">Many disagreed</a>, but with Messi not competing in London, Neymar is easily the one to watch.
