In tonight's episode, the British and Norwegian teams are struggling on in their bid to recreate the legendary Scott and great Amundsen's mammoth expedition of 1911/1912. And as if this wasn't enough, Gjeldnes's contemporary Norwegian team have set their own challenge of reaching the destination faster than Amundsen. For Bruce Parry and the British team things are about to get really tough. Two men have been injured and flown out, and now the team has the gruelling prospect of hauling two 500kg sledges with six men instead of eight. Bruce has a tough decision to make to - the whole team cannot go to the pole, so who will he pick and who is he going to send back?
