Sport: Swimming Nicknamed The Missile, Magnussen is spearheading Australia's hopes for gold this year. The confident Aussie's earned the fastest time in history in the 100-meter freestyle achieved without the aid of a speedsuit (they're now banned in international competitions). At the London Games, Magnussen, 21, has his sights set on one person in particular: Michael Phelps. "If you want to be the best, you have to beat the best," he told Sydney's Daily Telegraph in May. "I want the chance to race him at the Olympics…He's someone I have looked up to, but when I get on the blocks there is no love lost for anyone that I race against."
