The pound-for-pound sprinting king reclaimed an old crown on Sunday despite miserable conditions and a nagging injury. Usain Bolt won the 100 meter gold medal at the world championships in Moscow, Russia because he's still the best in the world. 

Bolt's 9.77 second time was his slowest in a major 100 meter final, according to the Guardian's Sean Inge, and he had to come from behind to earn the victory, but there's little reason to believe the 26-year-old is going to start losing any time soon. The track was wet after a downpour shocked the Russian crowd a few moments before the race. Lighting flashed across the skyline, too, leading to this fantastic AFP photo that was passed around Sunday afternoon:

Bolt also admitted to fighting through an injury Sunday to compete. "My legs were sore after the semi-finals, I don't know why, but the world record wasn't on so I came out just to win," he told the BBC after the race. Something seemed off at the beginning of the race when the reigning Olympic champion came out of the gates behind American sprinter Justin Gatlin, who finished second with with a time of 9.85 seconds. But the Jamaican motored forward, passing Gatlin with a little less than half way to go. 

Things went terribly the last time Bolt raced at the world championships. He false started twice and was disqualified in 2011. His fellow countryman Yohan Blake, who sat out this year with an injury, won the gold that year. "It's always great to get back your title," Bolt said after today's win. 

Some of Bolt's biggest rivals were absent Sunday after testing positive for performance enhancing drugs. American Tyson Gay and Bolt's Jamaican teammate Asafa Powell are both serving bans from the U.S. Anti-Doping Agency after getting busted last month. "I'm just doing my part by running fast, winning titles and letting the world know you can do it clean," Bolt said Sunday.
