Many of the riders starting on younger horses and it will be the first 3-star level competition for some.
Viktoria Carlerback, one of five Swedish riders in the field, won Malmo last year on her Olympic team horse Ballys Geronimo. This time she brings the newly upgraded Moustic de Canta.
One of the most experienced combinations is Katrin Norling with Pandora Emm, 19th and members of the 4th-placed Swedish team at the Olympics in Hong Kong last year. Niklas Lindback's two horses, Mister Pooh and Olivia, completed their first 3-star CCI at Boekelo last year.
For Belgium, Karin Donckers, who recently produced her country's best ever result at the Badminton Horse Trials when she finished seventh - rides the youngster Lamicell Charizard, while Carl Bouckaert has the seasoned Irish-bred grey Rampant Lion, 19th at the 2007 FEI European Championships and a team horse at the 2005 Europeans.
Finland, Lithuania, Norway, Poland and Germany, whose Olympic gold medallist Peter Thomsen rides Parko, are also represented.
