Training was intense for all the contestants, particularly Leigh, who was tested to the upmost by Shannan. The families were taken to the Challenge site, and told they had to carry buckets of water to the top of the sand dunes, tipping them into their barrel at the top to bring their key to the surface and release it. Sam and the Reds were the first to get their key, and release their flag for the win, giving the Challenors a 1kg weight advantage going into the weigh-in.
