Olympic gold medallist Usain Bolt has revealed that Prince Harry is down-to-earth, despite being a member of the Royal Family.

The Jamaican sprinter met the 28-year-old during the Diamond Jubilee visit to Bolt's homeland and the pair challenged each other to a race earlier this year.

"He's a really a fun person, so for me it was an experience that was not what I expected - because he's royalty," Bolt told Vanity Fair. "And he was really cool. So for me, it was a lot of fun."

Bolt clinched gold medals in the men's 100m and 200m finals as well as the 4x100m relay at London 2012 in the summer.
