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. Inspired by their UNICEF visits to Africa, they knew they had to go back and experience this extraordinary continent in more depth.

On October 6, 1973, Ted Simon knew there was no going back. He loaded up his 500cc Triumph Tiger in the pouring rain and said good-bye to London. Over four years he rode 64,000 miles round the world. Breakdowns, revolutions, war, a spell in prison, and a Californian commune were all part of his experience, which was colored variously by utter despair and unimaginable joy. He was treated as a spy, a god, a welcome stranger and a curiosity

In 1982, at the age of just 23 and halfway through her architecture studies, Elspeth Beard left her family and friends in London and set off on a 35,000-mile solo adventure around the world on her 1974 BMW R60/6. Reeling from a recent breakup and with only limited savings from her pub job, a tent, a few clothes, and some tools, all packed on the back of her bike, she was determined to prove herself. She had ridden bikes since her teens and was well-traveled. But nothing could prepare her for what lay ahead.

In less than a year, Neil Peart lost both his 19-year-old daughter, Selena, and his wife, Jackie. Faced with overwhelming sadness and isolated from the world in his home on the lake, Peart was left without direction. That lack of direction lead him on a 55,000 mile journey by motorcycle across much of North America, down through Mexico to Belize, and back again.

After six years of laying rubber on racetracks and immersing herself in the high octane, adrenaline pumping sport of motorcycle racing, Tiffani was yearning for something new from her life on two wheels. Fortunately (or unfortunately), losing her comfortable office job was the perfect opportunity to do exactly that.
