Hate him or love him, but Salazar did not run the tangents, not even close. It was measured in the early 80's following his footsteps that day the best that they could via using the race video and apparently still came up slightly short, 50 yards. Don't ask me how, but that's what I read.
The bummer on it is with all of the pre-race hype, national TV coverage mainly because of the WR prediction by Salazar, and it wasn't balls on accurate. I'm not blaming Mr. Katz, I'm just still shocked that it wasn't triple dog checked for accuracy. I realize too that the rules were apparently different back then.
Salazar ran 2:09:29 the next year, so did that time count? It's not Boston, it's New York.
All in all it was a total bummer for him. Look at his 1/2 marathon split that day, how accurate was that and if not, how far off could it have been?
