I'm selling two classic running books (more to come).
John Walker, Champion:
Deek: The Making of Australia's World Marathon Champion
I can't remember, exactly, it was on some site, there was also a podcast / interview with Dixk Quax(sp), I believe and he was just great.
Listened to that one first, and then was really looking forward to the JW one, and it was like WOW, what an sour old fart. It was shocking and sad.
Flotrack, in its very early, early days, did an interview with Walker. It was incredible- he gives really honest, frank answers. What comes across is that while he probably isn't an unfriendly man, he doesn't suffer fools (or foolish questions) gladly at all. It's not like you can get a lot from an interview like that, but he struck me as sharp, witty, a great friend to have on your side, and a bad side you do NOT want to be on. A friend of mine is from NZL and rides horses (so she knows him in that capacity, not a running one). She's been round his ranch/store and says he's very friendly/open about talking horse stuff, though, not being a runner herself, can't speak to how he might sound about running related stuff.
The highlight of the interview stuck with me. Floreani asks Walker if, in the 76 Olympics, he was worried about all those fast kickers being on his shoulder with 100 to go in a reasonably slow race. Walker responds something to the effect of (and forgive me for paraphrasing) "No, I thought I was 10 yards clear, and if I had looked back, I probably would have sh*t myself to see everyone so close."
