More than 600 horses are competing in the dressage, cross-country and show jumping elements of the international horse trials at Houghton Hall.
The competition began yesterday and continues until late afternoon on Sunday with the best of the cross country action today and tomorrow.
As host to the British leg of the Eventing Nations Cup competition there is a massive international entry headed up by the reigning world champion Sandra Auffarth from Germany, who brings three horses to Norfolk.
The British team for the Houghton leg is Sarah Bullimore riding Conpierre; a crowd favourite and the only ever winner of the Rolex Grand Slam of Eventing, Pippa Funnell riding Billy The Biz; Georgie Strang riding Ascot H; and Francis Whittington riding West Side.
The cross country dominates Saturday’s action, with more showjumping and the conclusion of the Nations Cup competition, while Sunday is a day of showjumping, and the conclusion of the CCI2* and Under 21 Championships. Tickets can be bought on the gate.
There is the usual raft of show jumping classes, both affiliated, unaffiliated and pony club, and team dressage. Visitors can also enjoy the Barking Bugle dog agility show.
