Kirsty Young's castaway this week is the Polar explorer Ann Daniels. Before she was 30, she hadn't so much as walked with a rucksack and had no experience of navigating with a compass. Then her husband saw a newspaper advert seeking ordinary women to join an all-women relay to the North Pole. Ann was successful and since then she has walked to both Poles, become a Polar guide and now has her sights set on being the first British woman to walk solo to the North Pole - an endeavour she'll attempt for the second time this March.

While she is on her expeditions, the life she leaves behind is also far from routine - she is a mother to four children including triplets. She has met some criticism for leaving her children for long periods, but she responds by saying that they are her inspiration - she wants to demonstrate to them how to live life to the full.
