Gayford retired before the 1972 Olympics to become an equestrian coach, judge, and course designer. He designed the jumping course at the 1976 Summer Olympics in Montreal, and headed the Canadian national jumping team from 1978 through 1996. He was inducted into the Canada's Sports Hall of Fame in 1968 and to the Canadian Olympic Hall of Fame in 1971.
