Tickets are on sale for the Nissan Chatsworth International Horse Trials.

Chatsworth (10-11 May) is the second of only two British qualifiers in the 2008 FEI World Cup series (the other being Burnham Market) and will count towards a final, which will be held at the end of this season.

The World Cup qualifier course will be in the hands of Olympic designer Mike Etherington-Smith, while the other courses will be designed by former five-time Olympian Ian Stark.
