In 1994, Gunnell added the European title to her collection, winning comfortably in 53.33. She also won the Goodwill Games ahead of Kim Batten, successfully defended her Commonwealth title and won the World Cup title in London. 1994 was her third (and final) year as the world's number one. She missed most of 1995 due to injury, an injury from which she would never fully recover. Her defence of her Olympic title in Atlanta in 1996 was cut short when she pulled up injured in the semi-finals. This seemed a particularly cruel blow, as this race occurred on her 30th birthday. Also in 1996, she worked as a Red Cross ambassador in Angola. In September 1997, she retired after a recurrence of an Achilles tendon injury forced her to pull out of the World Championships semi-final.
