Prince William is to open a three-day marathon in Anglesey on Friday.
The Duke of Cambridge will attend the start of the 135-mile Ring O’Fire race that sees competitors to circumnavigate the Isle of Anglesey in North Wales.
“His Royal Highness will meet a number of the runners and their families and a selection of volunteers involved in the administration of the race before officially starting the Ultra Marathon,” a spokesman for the Prince confirmed.
The engagement will be the new father’s second outing in Anglesey since the birth of Prince George. Earlier this month, William attended the Anglesey show where he thanked residents for their kindness since the couple moved to the area.
“I know that both of us will miss it terrible when my search and rescue tour of duty comes to an end next month,” he said in a speech.
“From the bottom of my heart, thank you for making my wife and me so welcome when we arrived here, as you do thousands of visitors each year.”
The Duke and Duchess of Cambridge are currently staying in Anglesey with their son Prince George, while William continues to work as a search-and-rescue pilot. On Monday, Kate was spotted for the first time since giving birth as she was photographed leaving a local supermarket with a full trolley.
The new mum appeared relaxed as she picked up supplies while Prince William and Prince George waited for her in the car.
The new parents are expected to move to London next month when William’s tour of duty finishes and the renovations on their apartment at Kensington Palace are completed.
Kate will make her first official public appearance on September 12 when she joins husband William as they attend the Tusk Trust Conservation Awards.
