Duncan is one of Britain's most instantly recognisable and well respected sportsmen. He tragically lost all his hair aged 10 and suffered with dyslexia which went undiagnosed until he was 14. Duncan took respite in the water and used his experiences to spur him on to success. After a disappointing Olympic debut in Montreal 1976, Duncan returned stronger than ever in Moscow 1980. Despite political pressures not to attend the Games, Duncan was adamant the Olympic Games should not be ruined by a short-term political event and his decision was justified when he won a gold medal in the 100m breaststroke. He followed this up with a bronze in the 4x100m medley relay and returned back to Britain a hero. Today, Duncan draws upon his experiences to motivate and inspire others, especially young people. He is actively involved with the Youth Sports Trust and many other charities.
