After their fantastic trip round the world in 2004, fellow actors and bike fanatics Ewan McGregor and Charley Boorman couldn't shake the travel bug. And after an inspirational UNICEF visit to Africa, they knew they had to go back and experience this extraordinary continent in more depth. Joining up once more with producer/directors Russ Malkin and David Alexanian and the Long Way Round team, and with two new BMWs loaded up for the journey, Ewan and Charley will set off on a new adventure, facing very different challenges. Riding from John O'Groats right down to South Africa, they will discover spectacular but unforgiving terrain, rich cultures and unforgettable local characters. Long Way Down tells their story - the drama, the dangers and the sheer exhilaration of riding together again. With their trademark humour and honesty, Ewan and Charley embark on their incredible journey, testing their endurance, biking skills and friendship to the limits - on the Long Way Down.
