In 1984, Cadbury Marathon was born as a small event. Since then, thousands of people have taken part in Tasmania's biggest marathon, some looking to set records and others to achieve their dreams of running a marathon. Cadbury has been a key supporter throughout the years. The race starts and ends at the Cadbury Factory in Claremont, Tasmania and includes a full marathon, half marathon, 10km, 5km and a 1km event for children under 12.
