Gillian McKeith's daughter breaks down on first challenge

Gillian McKeith's daughter breaks down on first challenge on The Summit. Just minutes into the 'tough to watch' premiere, Afton, 25, was seen sobbing to her co-stars and telling them she couldn't go through with the first challenge. The model and fitness coach had been tasked with a single-rope crossing at 'Paradise Gorge', 50ft above the ground, just 8km into the trail up the mountain.
