Strengths: Provides a good insight into what is obviously an often overlooked and highly underrated sport.
Weaknesses: I found the structure confusing and disjointed. There was too much detail and focus on past fell-running heroes, which all got a bit 'same-y' in the end.
Overall: I had expected more about the author's personal struggle to achieve his goal and less of a potted history of fell-running and its past heroes. There's only so much you can stomach about old guys living in unheated cottages in't North. Some of the history about the sport was interesting, in particular the amateur/professional conflict, but I felt the book lost focus at times and became more a series of anecdotes than a progressive story.
