The Rolex Kentucky Three-Day Event, one of the world's top equestrian competitions, returns to the Kentucky Horse Park on Thursday with a field of 75 horses and riders. Among them will be Zara Phillips, grand-daughter of Queen Elizabeth II, riding in Lexington for the first time. She will compete against her Olympic teammate and last year's Rolex Kentucky winner, William Fox-Pitt.
Also returning to Lexington for the first time since the 2010 Alltech FEI World Equestrian Games: German rider Michael Jung and his horse Sam, who won individual eventing gold medals at the 2010 WEG and 2012 Olympics in London.
Top American riders Buck Davidson and Phillip Dutton will be riding three horses each.
The Rolex Kentucky, which runs through Sunday, is the only four-star or Olympic level eventing competition in the Western Hemisphere, and one of six held annually worldwide. Prize money for this year's competition has been doubled to $100,000 for the winner, according to Equestrian Events Inc., which puts on the annual competition.
The Rolex Kentucky, along with Badminton and Burghley eventing competitions in Great Britain, are the $350,000 Rolex Grand Slam of Eventing.
