Lily loves fell running. She’s good, but never quite good enough: she gets anxious and loses her focus and then that’s it. Out. Plus she’s worried about her grandmother, who has Alzheimer’s and is growing distant and confused.

But whilst staying with her grandparents just before her first big race of the season, Lily discovers her great-grandfather was a runner too. Not only was he a fell running champion, but he was also a message runner during World War One.
