Phillips in action at Burnham Market on Toytown in 2007

Zara Phillips will be back in Norfolk for the 2008 Burnham Market Horse Trials between 28 and 30 March.

The world champion will be part of an entry boasting most of the likely Great Britain Olympic equestrian team.

The 840-strong entry list for the event will also include William Fox-Pitt, Oliver Townend and Mary King, who are all tipped to be in Beijing.

Event director Alec Lochore said: "It's great to see so many Olympians choosing us as their first event of the season."

Over the last four years our event has developed into the competition where world class riders start their seasons Alec Lochore

He added: "Burnham Market has always been popular with British riders and this year we have really good representation from Germany, Italy, Belgium, Holland and Denmark, so Burnham Market is now firmly established on the World Map.

"Over the last four years our event has developed into the competition where world class riders start their seasons.

"The international classes have grown for the fourth year running and the total prize fund is now well over �30,000."

Phillips will be bringing three horses, including Toytown, to the competition, so there will be plenty of opportunities for visitors to the event to see her in action.

Also bringing three horses are Jeanette Brakewell, last year's winner Townend and his girlfriend, Norfolk girl Piggy French.
