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.
