Royal fever swept the Olympics today as Zara Philips, the Queen's granddaughter who is 13th in line to the throne, put in a perfect performance in the challenging and dangerous cross-country round of the equestrian competition.
She was cheered on by an enthusiastic crowd which included all the young Royals: Wiliam, Kate, Prince Harry, Princess Beatrice and Princess Eugenie.
Her outstanding ride leaves her in joint tenth place overnight individually, and leaving the UK team int he silver medal position.
The 31-year-old, who made a solid Olympic debut in the dressage yesterday, managed to complete a clear round of the the cross country course in nine minutes and 55 seconds, comfortably within the time limit of 10 minutes and three seconds.
Before her run, several riders had fallen and horses slipped as they tackled a tricky course in historic Greenwich Park.
William and Kate applauded and cheered enthusiastically as she passed them in the main arena.
William wore a Team GB polo shirt and beige chinos, while the Duchess of Cambridge wore a dark blue blazer, white shirt and dark trousers.
William and Harry then went on to watch the British men's gymnastics team at the North Greenwich arena.
Sixty years and hardly a slip.
