Prince Harry Playfully Challenges Olympic Champion Usain Bolt to Sprint Race

The prince sent a birthday tweet to the runner called the "world's fastest man."

Harry, the fifth-in-line to the British throne, is known for his cheeky sense of humor. He congratulated Bolt on his 30th birthday via Twitter and threw down the gauntlet by challenging Bolt to a rematch of their 2012 race in Jamaica.

Prince Harry, 31, may be the only man who has beaten Bolt on the track, in Jamaica, no less. But, there was a catch: Harry got off to a fast start in his race against Bolt at Jamaica’s University of West Indies in 2012.

Bolt, who has won nine Olympic gold medals in all, responded to Harry's tweet for a royal rematch in the U.K. or Jamaica.
