Prince Harry: Invictus Games will help rebuild lives
31 July 2014 Last updated at 11:54 BST
The first ever Invictus Games, a series of para-sport events for wounded, injured and sick servicemen and women, begin in September.
Prince Harry has been heavily involved in the organisation of the event, after attending the Warrior Games, a similar event held in the US.
Sports range from indoor rowing to wheelchair rugby and Prince Harry hopes the opportunity will help rehabilitate injured and sick competitors and help get them back into employment.
He spoke to Chris Evans on BBC Radio 2 about why these games matter.
