Who's taking part in Race Across the World series two?
The second series has been extended by two weeks and will now air for eight weeks, with contestants competing to get from Mexico City to the most southerly city in the world, Ushuaia in Argentina.
Like series one – where contestants travelled from London to Singapore – they will need to travel thousands of miles without taking any flights or using a smartphone and with a limited set amount of money.
The 10 travellers will work in pairs to navigate across 16 countries via horse, foot, boat and bus to reach the finish line.
