The contestants were amazed to discover that in another Loser first, it would be the trainers weighing in. The results were a surprise to all, and not about to go unpunished. The contestants were woken at an unsociable 5am for a gruelling training session, after which they were given their bio ages by resident Doctor Swan. Each family member then recorded a video message to their future selves. That night the contestants were presented with their first Contest, endurance: a three-round, 10km race on the treadmills. Jodie, Leigh, Joe and Jarrod were chosen as the contesting champions, with The Blacks and Whites left at the final round.
