New Ninjas, new obstacles and a new location, this season is bigger than ever before. Heat one features six brand new obstacles including The Double Warped Wall.

It's heat two and the course changes up again. New contenders to take on the course include Raphaela Wiget and former-Wallaby Nathan Charles and pro-netballer Verity Charles.

50 everyday Aussies will take on the toughest obstacle course in the world with the goal of making it through the obstacles, up a Warped Wall and into the Semi Finals.
