Overview: While TV presenter and adventurer Ben Fogle undergoes an intensive course of treatment for a lethal tropical illness, Olympic gold medallist James Cracknell and new third team mate Doctor Ed Coats keep training for the race to the South Pole. Their dreams of reaching the South Pole look in tatters and James has to consider leaving his friend Ben behind. After four weeks of intensive and dangerous treatment, Ben waits for his results; will the doctors pass him well enough to face Antarctica? Thankfully, Ben is given the all-clear and the team pack, with only days to spare, and head off to their final time in the warm and sheltered climate of South Africa. On 18th December, all six race teams board their flight to take them to Antarctica. They set off on a final 10-day acclimatisation trek towards the South Pole, heading out into the polar wilderness on foot, pulling all they need to survive behind them in their sleds. Within days, they face the first of the many dangers Antarctica will throw at them. Big storms and blizzards blow in, forcing them to be tent-bound for days and threatening the start of the race.
