Final preparations are being made to re-enact the epic voyage of Sir Ernest Shackleton, the Antarctic explorer who battled to save his crew nearly a hundred years ago.
A team of mountaineers and scientists will make the journey using the same clothes, food and boat - and without any modern navigation tools.
