Princes Harry & William Pony Up

After several days of cheering on Olympians – including fellow equestrian and cousin Zara Phillips – Princes Harry and William saddled up Sunday for a game of polo.
The brothers squared off in the Jerudong Trophy Polo Match, held at the Cirencester Polo Club just outside London, to benefit a trio of charities close to both their hearts.
But by day's end, the two were back to playing spectator, joining Catherine, Duchess of Cambridge to cheer on Jamaica's Usain Bolt to another gold medal finish in the 100-meter dash.
