Six-time Olympic cycling gold medallist Chris Hoy tells the story of Colin McRae, Britain's first-ever winner of the rally world championship. He explores the driver's roots as a Scottish trials bikes star and travels over the dunes of the Sahara Desert along the route of the Dakar rally as he retraces a wide-ranging career. Colin's father Jimmy speaks about the helicopter crash that claimed his son's life in 2007, and the pride he still has in his many successes. Finally, Chris faces the challenge of taking on a stage of the RAC Rally, the event where Colin clinched his world title in 1995
