The 32-year-old royal created the international multi-sport event in 2014 to honour servicemen and women and has recorded a video message to boost the confidence of new competitors, telling them it will be a "life-changing" experience.

In the clip posted on the official Twitter page for the games, he says: "Some of you will have already been to an Invictus Games, while others will be taking part for the very first time and may be apprehensive.

"What you will experience in Toronto will be life-changing.

"They will support you and help you. Don't underestimate the power of that and please do the same for them."

Harry can't wait to cheer them all on from the stands and says it's a real honour to be able to thank all of them for their services and most of all "sacrifices" they've all made.

He said: "The Invictus Games is also a chance to thank them for all their support and sacrifices they have made.

"I'm really looking forward to meeting you in September. I'll be there in the stands cheering you on."

The video was captioned: "Prince Harry sends his good luck to all 550 competitors from 17 nations who will be competing @InvictusToronto in just a few weeks! (sic)"

Bruce Springsteen, Bryan Adams, Kelly Clarkson, Bachman and Turner and Couer de Pirate will be performing for the September 30 closing ceremony in Toronto.

Michael Burns, CEO, Invictus Games Toronto 2017 Committee said: "Talk about closing the Games with a bang! As a committee, we couldn't be more thrilled to add the iconic Bruce Springsteen to an already outstanding lineup of Closing Ceremony talent. We wanted to deliver memories from these Games in Toronto, and this represents the culmination of two years of planning and work."

550 injured service members and veterans from 17 nations will compete in the third annual Invictus Games.
