Ironman legend Dean Mercer has died at the age of 47.
The father of-four passed away at Gold Coast University Hospital after crashing his SUV through a fence at Mermaid Waters early this morning.
According to reports, Mercer suffered a medical condition at the wheel. Paramedics rushed him to the emergency department where he went into cardiac arrest.
Mercer grew up in Thirroul on the NSW south coast and competed professionally for nearly three decades.
Throughout his illustrious career, he won five state NSW championships, two Test of the Toughest titles, the 1997 World Oceanman series and two Australian Ironman titles.
Mercer retired in 2010 and was inducted into the NSW Hall of Champions in 2014 alongside the likes of Dawn Fraser and Don Bradman.
