BR - thanks for expanding on why you disliked it. Fair enough, we are all different people with different thresholds and sensibilities. I agree absolutely that Askwith came across as a journo (he is a journo of course) looking for something to write about, but this didn't offend me. Many, perhaps most books start life like this. The acid test for me personally is not the motivation, but whether they succeed in moving me. In theory, given her eminence, Radcliffe's book should have knocked me for six, but didn't, because her ghost writer was as inept as she is talented.
You're right - Askwith did adopt a "tone" that was noticeable. For reasons that are bound up in our different characters, the tone worked for me, but not for you. No value judgement here.
One other thing that did occur was whether your superior running ability / determination or whatever, made you resent him, for articulating what you already know; whereas for me, he is so remote from my experience that I can't help but find his story fascinating.
You said something else that was interesting:
"Even though some running books are dull... at least they arise out of having accomplished something first for the sake of the sport, rather than someone taking mental or actual notes all the time to put into a book."
That's another difference. I'm not that bothered about achievement 'per se'. In fact, I think this might be it. I'm more interested in the journey than the destination. You are more goal-driven. You're a competitive runner, while I'm a plodder who knows his place -- at the back of the field, happy to observe what's going on.
I guess this translates into the way we assess running writing.
It comes down to this distinction that's been mentioned before -- runners who discover writing; and writers who discover running. I much prefer the latter. I suspect you like the former.
As they used to say in Moss Side: "It's allowed".
