In training for those world championships, she won the New South Wales Duathlon Championships in the 20-24 age group. She finished second in her age group in Kona.[citation needed]
In 2004, she won the 18-24 age group at the Australian Ironman for a second year. At the World Championships she finished third. She turned professional during 2004.

On 30 July 2016 Marangon released a statement[4] that she will receive a four year ban by the Australian Sports Anti-Doping Authority for testing positive for the banned substance Ostarine. The test result originated from a sample taken in January 2016 at the Challenge Melbourne event, where Marangon finished 5th.[5]
