Philip, 95, took his carriage out for an early morning trot through the park beneath Windsor Castle as the annual Royal Windsor Horse Show got under way.
The royal drove the carriage of four horses under some trees along the River Thames. As he called out an order for them to keep along the right lines, he briefly turned off the track and drove along a grassy bank by the water’s edge, before rejoining the path and heading into the showground areas.
He then rode the carriage back to Windsor Castle, where he and Queen Elizabeth are staying. Philip, who used to compete in carriage driving, likes to keep active with the hobby at Windsor and on the estate at Sandringham.
His morning trot came a day after a very memorable blast from the past. On Tuesday, he met his match when an old sea-faring colleague dubbed him a “very randy” sailor in his younger years.

While Philip enjoyed his scenic ride, the Queen — with a headscarf covering her hair — watched her heavyweight horse Tower Bridge compete and win second place.
She is expected to attend the Horse Show through the week until Sunday. She is regularly joined by members of the royal family as she checks up on her horses and takes in the competition.
