He has raced against Usain Bolt, played volleyball on a Rio beach and cooked doughnuts for the press, but now Prince Harry completed his most unusual feat - joining a human pyramid.
On day four of his US tour the Prince, 28, joined cadets at a US Air Force academy in Colorado Springs for an American Football training session, during which he also watched a display of gymnastics by the cheerleaders.
The third in line to the throne gamely got down on all fours to help form a three-tier pyramid with a man dressed as a bird at the top.
The Prince also managed to rope in Britain's most senior military officer in the US, Major General Buster Howse, military attache to the British embassy in Washington, who crouched down beside him.
Two cheerleaders crouched on top of them and the mascot of the US Air Force Academy's Falcons gridiron team formed the apex.
