Kate Humble talks to Julia Wheeler about the benefits of walking and her book Thinking on My Feet in which she recorded her walks (and runs) throughout a single year, but also charted her feelings and impressions throughout.

She looks at the reasons why we walk – whether for creative energy, challenge and pleasure, or therapeutic benefits, and offers reflections and insights that will encourage, motivate and spur you into action. In her book she also included walks with others who have discovered the magical, soothing effect of putting one foot in front of the other, including the artist who walks to find inspiration for his next painting and the woman who walked every footpath in Wales (3,700 miles) when she discovered she had cancer.
