Steve Backshall is one of our leading natural history broadcasters; he's also an extreme sportsman who has conquered some of the world's most dangerous mountains. Despite suffering a severe rock-climbing injury in 2008 he continues to set himself extraordinary challenges.

For this edition of One to One, Steve meets explorer Ann Daniels to discover what drives her need for adventure: Ann is the record breaking polar explorer who, in 2002, became the first woman in history (along with a teammate) to have reached both the North and South poles as part of an all-woman team.
