He betrayed the cult, the inner sanctum. Serious competitive and elite runners get to where they are by long, hard, painful work. And none of their non-athlete friends and relatives get it ("Why do you put yourself through so much pain?"). But the serious runners get it, and that forms a bond among them, a blood pact. They like the cult status and actually enjoy that others "don't get it." In the early 70s Galloway was charter member of that hardcore running cult, he ascended to its heights. But now he betrays it. And the thing is, he didn't HAVE to. Serious runners would still respect him if he simply said at the beginning of his books:
"When I was young in the early 70's, I ran like a maniac, an animal. Shorter, Bacheler and I beat each other's brains out. It was soooo painful, and we loved every sweat-soaked, gut-wrenching second of it. And where did all that pain and agony get me? To the freaking OLYMPICS, man. Doesn't get any better than that. BUT, I am now, like a lot of people my age at a different point in my life (job, marriage, kids, etc). So I run differently now, for different reasons. And although its apples and oranges, I enjoy it just about as much as in the 70s, but for different reasons. So if you are or want to be the kind of animal I was in the 70s, I get it, go for it, I hope you enjoy it as much as I did. However, you should then look elsewhere for running advice. But if your life situation or aspirations are more like where I am now (you want to finish races more than win them, you do not want too much discomfort in races, you want to focus your training more on avoiding injury than on getting better faster, etc.), then I think my books will help you."
That's all he had to say.
