After racing nearly 13,000 kilometres over seven weeks through China, Nepal and India, the four teams are about to embark on the final leg of the race. From the Great Wall of China to the southernmost tip of India, at Kanniyakumari, the teams have journeyed through the two most populous countries in the world and are now just 1,200km from the finish line, with a prize of £20,000 for the winning team. As the race comes to an end, the teams all take a moment to reflect on their experiences. Relationships have been tested, bonds deepened and memories made. Which team will triumph and be first to reach the book on the finish line?
