The Challenge - Season 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.

After the first elimination, the game gets real! The first alliances are formed heading into the second Challenge, where their endurance and memory are put to the test. The Challengers quickly realise they are only as strong as their partners, and it will take a lot more than just physical superiority to take home a victory in this game. Power proves to be complicated for the Challenge winners when they are forced to choose between alliances and friends. Meanwhile, romance in the house heats up as one Challenger decides it's better to play hard to get.

The Challenge is in full swing, and the name of the game is to survive another night. At the Getting Tyred Challenge, Challengers have to solve puzzles and tasks for points. Model and Love Island star Arabella Chi is faced with her first major decision of the season. Does she side with the strongest alliance in the house, or does she stay loyal to an old friend? Meanwhile, romance is at an all-time high as two Challengers take their relationship to the next level.

With the final in sight, alliances begin to fracture. After the Frozen Senseless Challenge, friendships are tested as one player questions if £50,000 is worth the real cost to her associates.

All the sacrifices come down to this! The remaining Challengers put it all on the line as they race across the Argentinian countryside for their share of £100,000, the title of Challenge UK Champion, and their chance to represent the UK in the Challenge: World Championships, where they will compete against players from all across the globe. Host Mark Wright will make it challenging for the Challengers as they race all day, testing their endurance, stamina, strength, and smarts. These players will have to earn their right to take home the crown, the money, and the title of Challenge UK Champion.
