Bolt's time of 19.55 seconds is the fastest time of 2015, his fastest time since the 2012 Olympics, and his fifth-fastest time ever. And he did it while pretty much jogging in the last five meters.

Bolt came into the World Championships in the unfamiliar role of the underdog. He had a miserable year because of injuries and a lack of training. His fastest 200-meter time in 2015 was 20.13 seconds - well behind Gatlin's world-best of 19.57 seconds.
But in Beijing, Bolt showed why he's still the world's greatest sprinter, even at age 29. He won the 100 meters, and then followed it up by blowing everyone away in his favorite event. Check out the celebration before the race is even over:
