Toughest task yet for tribesman'.
The presenter of Tribe is part of the expedition recreating Scott and Amundsen's fateful race to the South Pole in 1911.
The first two episodes of Blizzard: Race to the Pole (BBC2, Sunday and Wednesday) see the British and Norwegian teams, led by Parry and Rune Gjeldnes, start their 1,550-mile journey using only original equipment, clothing and food.
The setting is Greenland, because dog-sledging is now banned in Antarctica, in case they pass on deadly diseases to the seals.
Roald Amundsen won, but it was Robert Scott who died a hero. The British team's chances of reversing history are hampered when a violent blizzard strikes the camp, and one injured member has to be flown home.
