That's B.S. You did make claims about him that haven't been verified: the 200 and 300-mile weeks. Let's face it: they aren't believable. He clearly lied a lot, so anything that he says that sounds unbelievable shouldn't be believed. For instance, his description of how he almost ran the first sub-2-hour marathon, but collapsed just before the finish, is clearly not true, and not even based a real event.
Yes, the guy was good. Best male US high school runner ever, quite possibly. But there is no reason to think he trained much differently to any other runner of his caliber. The only reason to believe, for example, that he ran a weekly 88-mile long run is that he said so. But he's the same guy that said he barely missed a sub-2 marathon which was basically at his 10k pace. When anybody calls B.S., guys like you always start pointing out that he was really fast and had a tough childhood. Fine, but that doesn't mean he's not a liar. If his best-ever result was 27:11 for 6 miles, then he probably did training runs, workouts, long runs, etc, that were similar to other people of that caliber.
The problem, as I see it, is he has spouted so much garbage about his supposed accomplishments, that some people think, wow, at least SOME of it must be true. They use outlandish claims he made to back up other outlandish claims he made. He was fast, after all. If he didn't do 350-mile weeks, he probably did something close to that, right? After all, he said he would go out for 10-milers in the middle of the night, just for the heck of it! And he did 88 mile every Sunday! So if he wasn't getting 300 a week, he was probably at least getting 200-250. And so on.
I suggest, stick to facts that are ACTUALLY verified. He set some great HS records that stood for ages, and he once tied for a 6-mile WR. He was one of the top distance runners in the world for a while. Nothing more, nothing less.
