THE LEGS GO FIRST, SO THEY SAY, AND though in the long run Princess Diana is still No. 1 in the hearts of most Britons, in the short run—specifically the 80-meter dash—30-year-old Di may be losing some ground. Consider her performance in the annual Mummies' Race at Wetherby, the school attended by her younger son, Hairy, 6. Togged out in a beige skirt and navy-blue bolero jacket and running against 17 other moms, Di slipped to fourth place after finishing first, then second, then third the previous three years.

No matter: The mere presence of Prince Charles, 42, at the event was a victory of sorts for the Princess. His back injury forced Charles to the sidelines for the equivalent Daddies' Race, but he smiled and clapped—and sketched the festivities in pencil—as wife and son carried the family standard. Sorely missed was Harry's brother and Wetherby alum, Prince William, 9, who now boards at Ludgrove school. Wills was holed up at Kensington Palace recovering from his recent head injury.
