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 but now feels fraught with danger. 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 who scaled the Alps in woollen skirts and photographed fearless women climbing, skating and tobogganing at breakneck speeds. Telling Lizzie's story alongside her own, Rachel runs her way from bereavement to belonging, inspired by the tenacious women, past and present, who insist that breaking boundaries outdoors is, and always has been, in her nature.
