Jamaican track and field demigod Usain Bolt is currently the fastest man in the world, but his reign will be tested once more at the 2012 Olympic Games.
He completed a three-race sweep for gold at the 2008 Summer Games, winning the 100-meter, 200-meter and 4x100-meter sprints. His accomplishment was on par with what Michael Phelps did in the pool that year, and he has his sights set on more glory this year.
He's not the only talented sprinter in the field in London, though. American sprinters Tyson Gay and Justin Gatlin have come on strong leading up to these Games. Additionally, Bolt's own teammate, Yohan Blake, is nipping at his heels.
With that in mind, let's take a look at how the top sprinters in the world stack up against one another in a good, old fashioned power ranking.
