Career
Born in 1937, Willcox began riding in childhood, and participated in Pony Club. She rode in her first three-day event with partner High and Mighty, an Arabian/pony cross, in 1955 at the young age of eighteen. Her first ride around Badminton occurred a year later, where she managed to capture second place.
Willcox also competed in the 1957 European Championships with High and Mighty, earning both team and individual gold medals.
However, women were not allowed to ride in the Olympic Three-Day competition at this time, and so she was unable to participate. Her mount was sold to Ted Marsh, to be used by the British Team, although High and Mighty was, in the end, never selected.
Sheila Willcox married, becoming Sheila Waddington, and returned to Badminton in 1959 with her new, and inexperienced, mount Airs and Graces. Willcox competed successfully for several years, winning eight major titles.
However, a fall in 1971 at the Tidworth Horse Trials left her partially paralyzed, and she gave up eventing and focused on dressage.
She went on to gain success in this equestrian sport as well, reaching the Grand Prix level on Son and Heir.
