EVERYTHING YOU NEED TO KNOW ABOUT THE EXPEDITION:

The first expedition to the South Pole and back again, unsupported

Capt Scott - The last person to try to walk back from the Pole.  In November 2010, John Wilton-Davies and Justin Miles of Great Britain will attempt to become the first people to reach the South Pole and return, completely unsupported. No resupplies, no dog sleds, no kite skiing.  Nothing.  The longest unsupported polar journey in history.
