A very well articlutaed post there RC.
My favourite running books of all time are the Ron Hill autobiographies and the Bill Adcocks `Road to Athens'. Neither of them are particularly well written (or badly written for that matter, but they don't set out to amuse and entertain) but they encapsulate the struggle and determination to get the very best out of yourself, with the pitfalls of going too far on occasions.
These are the type of books were they got out and ran hard, then at the end of their career thought they might have something worthwhile to write about whic others might want to read.
For me too much of the FITC book was not about running; it was about Mr Askwith. The best bits (which I admit were very interesting) were when he was interviewing the top fell runners.
