When Rachel loses five family members in five months, grief magnifies other absences. Running across moors and mountains used to help her feel at home in her body and the world, but now she becomes painfully aware of her inability to run without being cat-called or followed by strange men, or to walk alone at night without fear. Her eyes are opened to injustices facing women in sport, from men who push her off paths during races, to male bias in competition regulations, kit and media coverage. The outdoors becomes a place of danger, sharpening her sense of the grief women experience – every day, everywhere – for lack of freedom.

Rachel goes in search of a new family: the foremothers who blazed a trail at the dawn of outdoor sport. She discovers Lizzie Le Blond, a courageous Anglo-Irishwoman who scaled the Alps in woollen skirts, photographed fearless women climbing, skating and tobogganing at breakneck speeds, and founded the Ladies’ Alpine Club, defying men who wanted the mountains to themselves. Yet after such groundbreaking progress in the late 1800s, a backlash drove women out of sports and public space.

Are we now living through a similar reversal in women’s rights or an era of unprecedented liberty? Telling Lizzie’s story alongside her own, Rachel runs her way from bereavement to belonging, in a world that feels hostile to women. On the way she’s inspired by the tenacious women, past and present, who insist that breaking boundaries outdoors is, and always has been, in her nature.
