Avsnitt 6

How well do you know your city? Well enough to beat a local taxi driver in a race across town? In this episode, Alexis hops behind the wheel in London, and challenges its legendary black cab drivers and their knowledge of the city to a race across the capital. Then, with the odds stacked against him in unknown territory, he attempts to out-smart a professional tracker and his team of sniffer dogs in America’s Blue Ridge Mountain Range . Once this ultimate evasion challenge is over, Alexis needs to win against a grandmaster of memory. But who will come out on top - man or expert?
