Equestrian
Founded in 1993, the Equestrian Club has gone from strength to strength. Over 50 pupils are involved in showjumping, eventing and hunter trials. Success has come at all levels in all disciplines. In 2005 teams from Kilkenny College won both the senior and junior competitions at the All- England Showjumping Championships at Hickstead in England.  Former members have pursued their interests in the equine world, including Classic winning jockey, Jamie Spencer. Meetings, excursions, table-quiz evenings help fill a busy calendar. Pupils may go trekking or take showjumping and dressage lessons by arrangement. Every support and encouragement is given to our riders whatever their ability.
