James Cracknell & Ben Fogle's show On Thin Ice Starts Sunday
This new BBC 2 series follows the adventurous duo and their third team member (originally Johnny Lee Miller and then Ed Coates) as they attempt the first organised race to the South Pole.
Facing extreme weather conditions, training in how to avoid, frost bite and hypothermia and deal with the constant cold, winds and altitude, the trio set their faces towards a challenge of a lifetime.
