It's hard to keep an athlete away from the field for too long.
After several days of cheering on
Olympians – including fellow equestrian and cousin Zara Phillips
– Princes Harry
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.
