IRISH-bred horses dominated Saturday night’s Tattersalls RoR ridden showing supreme championship at Aintree where the Jane Williams-ridden Hazel Hill claimed the title while last year’s winner, Rich Man Poor Man, stood reserve under Kirsty Douglas.

Over four days of competition in the Aintree International Equestrian Centre, nearly 300 former racehorses took part in The Jockey Club RoR National Championships which featured arena eventing, dressage, in-hand and ridden showing classes, show jumping and working hunter competitions.
