The Duke and Duchess of Cambridge attended the Ring of Fire race in Anglesey, Wales, where they are currently living as William wraps up his Royal Air Force duties there. Kate's appearance was a surprise, and she came out to thank members of the local community for their support, according to Sky News.
The new parents stood on a grassy hill overlooking the bay, joining the crowd as they counted down from 10 to kick off the race. William rang the bell to signal the start to runners participating in the three-day 135-mile foot race along the coast.

The new mom has kept a low profile since debuting their son outside the Lindo Wing of London's St. Mary's hospital a day after he was born. William returned to work -- and the spotlight -- soon after the birth and charmingly compared his military duties to raising a son.
The royals also gave the world a glimpse of their provincial life by sharing informal family portraits of themselves, George and their dog last week. The duchess' next scheduled official appearance is Sept. 12, when she's to join William at the Tusk Conservation Awards in London, the Daily Mail reported.
Kate, 31, already looked pre-baby perfect at the race. She paired a green Ralph Lauren blazer with a patterned silk blouse by Zara and snugly fit her already slim figure into a pair of dark J. Brand skinny jeans, according to People magazine and the Daily Mail.
The first-time mom stayed fit by walking her dog, Lupo, and taking regular "ante-natal" yoga classes while she was pregnant, the Mail reported.
She said that their 5-week-old son was at home napping with his grandmother, Carole Middleton, who came to babysit.
"He's doing very well," Kate told Sarah Bingham, 38. "He's with granny at the moment. He's sleeping well but I know these things change at a minute's notice."
The new mom described her son as "sweet" and told another event-goer that she was keen to get back into shape -- even though what little baby weight she gained appeared to have already melted off.
