Not addressing the subject of this thread, but:
1. Salazar ran more than 42.195 K that day in 1981. Anyone can watch the tape, like I did, and GPS what he ran, like I did, to see that.
2. The bigger tragedy here is that in 1981, and throughout the 70s actually, the marathon World Record was set a half-dozen times, yet Clayton's suspicious 2:08:34 was held up as THE WORLD RECORD.
Salazar's record was not, eventually, but it didn't matter once Deek ran at Fukuoka a few weeks later.
All you millenials claiming every single course on earth was short until you ran a road race need to zip it. The dude who claims they took a shortcut over the "dirt path" is retarded, plain and simple. I've gone over probably two or three dozen courses I raced in the 70s and 80s with GPS and phone GPS, and found just as many discrepancies with today's courses. Some are short, some are long. NYC is currently long. In 1981, a precise tangent route LIKE THEY RUN EVERY YEAR AT BERLIN, CUTTING OVER SIDEWALKS ON CORNERS, would likely make that course short. The way Salazar ran, it was not short.
