“The Duke met representatives from the @royalmarines runners’ contingent, including two Royal Marines who have completed the entire 1664 miles,” the royal family shared on their official Instagram alongside a slideshow of highlights from the day. “His Royal Highness also spoke to veterans and cadets before returning to the dais to receive the 1664 Global Challenge baton.  The Royal Marines are the amphibious troops of the Royal Navy, acknowledged as one of the world’s elite commando forces.”

The duke received three cheers from marines and was handed the 1664 Challenge Baton during the parade. He was appointed Captain General of the Royal Marines in 1953.

The Royal Family broadcasted the Duke’s last day of work on their official Facebook page on Tuesday.
