In Advanced Intermediate classes the horses are asked to perform an Advanced dressage test such as they might perform at Badminton or at the Olympics, to jump an Advanced show jumping course and to jump an Intermediate cross country course. A tyre and palisade combination fence near the end of the cross country course demanded a great deal of accuracy and claimed a notable scalp when Olympic and World Champion, Blyth Tait, riding Chesterfield, was eliminated there.
