The slogan for this year's Devon Horse Show and Country Fair is "Devon: The Tradition Continues."

That is certainly a fitting motto for an event that began in 1896. This year, however, a new tradition has been born.

The Grand Prix of Devon, arguably the signature of the 11-day event, now bears a horse's name - Sapphire.

"That's going to be an exciting event," said Carrie Wirth, a press officer for the show who works for the Phelps Media Group.

The Sapphire Grand Prix of Devon is a two-round event in which riders and their mounts navigate a course with jumps up to five feet high and six feet wide.

Its namesake was the mount of show jumper McLain Ward, 39, who retired the mare after winning two team gold medals at the 2004 and 2008 Olympic Games.

"He has won the class more than anyone in the history of the class," Wirth said of Ward.

Ward, currently ranked fourth on the Rolex/USEF Show Jumping Ranking list, will compete against top riders from the United States and around the globe.

The Devon Horse Show and Country Fair has raised an estimated $47 million for the Bryn Mawr Hospital since 1919.

"It's a Pennsylvania treasure and treasure for the equestrian world as well," Wirth said. "People come from all over the country and the world to compete here."
