The Duke of Edinburgh paid tribute to thirty British and American war veteran amputees on Friday.
Prince Philip greeted the servicemen who will be taking part in a charity cycle race to raise money for the Wounded Warrior Project, BLESMA and ABF The Soldiers' Charity.
The Soldier Ride UK Challenge will begin at the royal family's Sandringham Estate in Norfolk and finish 250 miles later in London on Thursday.
A Northern Ireland veteran, Pat Provis, lost his left arm and the majority of his right hand in an explosion last year, also took part in last year's challenge.
He said: "It is a challenge, especially when it is as hot as it was last year."
"The guys on hand bikes had to work extra hard work on some of the hills, but we all helped each other along and didn’t leave anyone behind. We had chance to really talk to the other riders, and we really had so much in common, it was a fantastic experience."
