This year’s first Ironman regional champs will get underway in Melbourne, Australia on Sunday (22 March), with a furious battle expected in the women’s race between Kona 2014 winner Mirinda Carfrae (AUS) and defending champ Caroline Steffen (SUI).

Held since 2012, Ironman Melbourne begins with a one-loop 3.8km sea swim off the coast of Frankston, a town south of Melbourne, followed by a 180km two-lap bike route along the Eastlink Tollway, a major expressway closed for race day. The point-to-point 42.2km run also starts in Frankston and finishes in the beachside neighbourhood of St Kilda. 

Steffen has reached the podium for the past three years running, winning twice (2012 and 2014) and placing third in 2013. Carfrae on the other hand has never won it, her best result in Melbourne being bronze in 2012.
