Kilkenny (aka "Henry"), a bay gelding owned by Mrs. Dorothea Wofford, competed in two Olympic Games with rider Jim Wofford (who was inducted into the Hall of Fame in 2003) in 1968 and 1972, winning team silver medals in both Games. He and Wofford also won the individual bronze at the 1970 Eventing World Championship in Punchestown, Ireland, and competed at the Badminton Horse Trials in 1968. In addition, Kilkenny also competed with Tommy Brannan at the World Championships at Burghley in 1966.
According to Wofford, "Henry was an impressive horse with a trot that had all four feet off the ground and a gallop that took a young man to enjoy. He was disdainful in dressage but tolerated it because of his strong desire to please. He took a fierce hold cross-country, but I rode him throughout his career in a snaffle because I then held the belief that my horse's affection is the strongest bridle of all and believe that to this moment. He was afraid of only two things: bagpipes and not trying hard enough.”
