Race Across the World

After racing nearly 13,000km over seven weeks through China, Nepal and India, the teams are about to embark on the final leg. Just 1,200km stand between them and the finish line, with a prize of £20,000 for the winning pair. They must travel through India's southern states, a region with a distinctly different flavour, with new languages, cuisines and traditions. And with only seven-and-a-half-hours separating the top three pairs, there's no way of knowing who will be first past the post
