At the 1920 Summer Olympics Ainsworth-Davis ran the third leg for the British 4 × 400 m relay team, which won the event. He also competed in the individual 400 m, to replace Cecil Griffiths who fell ill, and finished fifth.
After graduating from University of Cambridge Ainsworth-Davis studied medicine at St. Bartholomew's Hospital and played music at a nightclub to support his family. He could not make time for sport, and retired from competitions after placing fourth in the 440 yards at the 1921 AAA Championships. He became a respected urological surgeon and the Secretary of the Royal Society of Medicine. During World War II he was head of the surgical division of the RAF hospital at RAF Cosford. Later he served as Secretary and President of the Hunterian Society (1958) and Secretary of the Royal Society of Medicine.
Ainsworth-Davis married Marguerite C. Wharry in 1920, with whom he had three children: Mary (1923), John Christopher (1924) (an actor/director/author who wrote under the pen name of Christopher Creighton and used the name John Ainsworth in the theatrical world), and Jennifer (1930).
