Usain Bolt may be the current king of the speedsters, but after gaining the title of "fastest man alive" in Beijing in 2008, it looks like London might be the city where this king finally gets dethroned.
The competition has stepped up for Usain, and the title that he gained in Beijing may not be his for much longer.
Tyson Gay is already the fastest American, but that title is not enough for this hungry competitor. He wants more, and he knows that in order to make his mark on history he needs to challenge and defeat Bolt—a challenge he may just rise to.
Unable to compete in Beijing because he was serving a four-year ban for testing positive to banned substances, Justin Gatlin is ready to make up for lost time.
The Brooklyn native is already making a splash after becoming the fastest man over the age of 30
But with Gatlin's age comes experience, and that just might be what pushes him over the edge.
Known to suffer from pre-race anxiety, this may finally be the year when Asafa Powell learns to control his nerves and takes Usain Bolt and the world by surprise.
Known for being good friends with Usain Bolt, the friendship between the Jamaican superstar and Wallace Spearmon may soon come to an end—at least for the few seconds when they will be racing against each other.
Perhaps Usain Bolt's biggest competitor, this up-and-coming star has already made the news for beating Bolt during the Olympic trials.
If there is any man on earth who can beat Usain Bolt in London, it is probably Yohan Blake—and that's a prediction you can take to the bank.
