Episode 1

Sixteen of the UK's finest stars from sports and entertainment join host Mark Wright to fight for their share of £100,000 and the title of Challenge Champion. These stars have a track record full of parties, hook-ups, and memorable one-liners, but none have ever played The Challenge before. Contestants are shocked by the gruelling nature of this new competition, which not everyone will leave unscathed. Will these titans be able to adapt and thrive in this treacherous new terrain of brutal athletic battles, political betrayals, and sultry distractions, or will they fall apart as the pressure builds throughout the season? Participants are: Kaz Kamwi, Danni Menzies, Aisleyne Horgan-Wallace, Kaz Crossley, Courtney Veale, Zara Zoffany, Ella Rae Wise, Arabella Chi, AJ Pritchard, Curtis Pritchard, Callum Izzard, James Locke, Tristan Phipps, Ashley McKenzie.
