Raising his hands aloft in victory, Prince Harry celebrates winning a race against the world's fastest man.
On a visit to Jamaica on behalf of the Queen in her Diamond Jubilee year, the royal had a special training session at the University of West Indies with Usain Bolt.
Being the good sport he is, the champion stepped off the gas halfway through their race.
He then showed him how to perform a victory dance.
Usain is a track hero after spectacular wins over 100 and 200 metres at the Beijing Olympics in 2008.
Later in the day, the Prince was due to visit two children's hospitals.
An engagement at a project called Rise Life, for young people in a deprived area of Kingston, was also on the agenda.
