Prince Philip's final public engagement was hailed as "historic" by a Royal Marine.
The 96-year-old royal's last official event featured men from the Royal Marines and has been talked up by Cpl Thompson, who ran 1,664 miles over 100 days in aid of the Royal Marines Charity.
He said: "This is historic because this is the Duke's last royal engagement and we're a part of it, the Royal Marines are a part of it - so it's an absolute honour."
Elsewhere, Lieutenant Colonel Gary Green, who devised the 1664 Global Challenge, was delighted to play a part in the Prince's last official engagement earlier this week.
He explained: "It's an honour for the Armed Forces having the Duke of Edinburgh's last public engagement with the Corps and the Royal Navy - it's brilliant, we're delighted."
And Lieutenant Colonel Green said Prince Philip still serves as an inspiration to people in the Armed Forces.
He shared: "The Duke of Edinburgh is all about challenges, he's all about charity work and helping people and having somebody like the Duke as head of the Royal Marines, it just helps the Corps with our own challenges.
"With somebody who's head of the Corps, who's quite exceptional in what he does, it makes the Corps exceptional, it builds our Commando spirit and he's a wonderful figurehead for all Royal Marines to look up to."
Although Prince Philip's royal duties have now officially ended, Buckingham Palace recently confirmed that he may still attend the occasional event alongside the Queen.
