Kate Middleton shared a sweet photo of her son Prince George nearly towering over her during an outdoor family outing.

The Princess of Wales posed with her arm wrapped around her tall 12-year-old after completing last week’s National Three Peaks Challenge to support The Royal Marsden Cancer Charity, per an Instagram photo posted on Sunday.

Younger son Prince Louis, 8, also appeared in the snap, tugging on Middleton’s arm, as daughter Princess Charlotte, 11, stood nearby.

Middleton appeared to be the only one who participated in the challenge, as she sported workout gear and a backpack.

Another photo she shared showed the four chatting with Prince William, who was also there to support his wife.

In additional snaps, Middleton clasped Louis’ hand and held Charlotte tightly.

“This time last week, completing the National Three Peaks Challenge,” she captioned the photo dump. “A huge thank you to everybody who has supported The Royal Marsden Cancer Charity.”

The challenge is a 24-hour endurance event that involves climbing the highest peaks in Scotland, England, and Wales, covering 23 miles and an ascent of 10,052 feet, often in adverse weather and in the dark.

Prince William and Middleton were a no-show at Taylor Swift and Travis Kelce’s New York City wedding on Friday — but reportedly met up with the bride and groom ahead of the ceremony.

The royals secretly linked up with the couple, likely when the Grammy winner and NFL player, both 36, were in London in May, People reported on Saturday.

Kelce hinted at the meetup in Friday’s surprise “New Heights” podcast episode with the Prince of Wales.

The future king himself had hinted they might make an appearance at the star-studded wedding.

In a May “Heart Breakfast” radio interview, William teased that he had “no comment” when asked about the event.

However, he added at the time, “I’m hoping, and I’m sure there might be an invitation around, but we’ll see.”
