What can the worlds of mountaineering and endurance running reveal about changing ideas of freedom, identity and the body? Laurie Taylor talks to Sarah Lonsdale, Senior Lecturer in Journalism at City, University of London, about her new book Wildly Different - her study of early 20th‑century women who sought autonomy through outdoor adventure. She focuses on the mountaineer Dorothy Pilley, whose Alpine achievements and reflective writing challenged prevailing assumptions about femininity and physical capability.

In 'Dirtbag Dreams', Carl Morris (sociologist, historian and social psychologist from the University of Lancashire) explores the history of mountain, ultra and trail running in the US and Britain from its origins right up until today. He asks if the ever-increasing popularity of these sports risk making them overly commercial and corporate? A keen fell runner himself, Morris examines the distinctive values that shape these endurance communities, including ideas of authenticity, self‑sufficiency and the pursuit of physical extremity.
