There's a thread on Letsrun.com hypothesizing that the reason US marathoners ran such good times back in the day was the courses were short.

Among the responders is Benji Durden, one of the top American marathoners of the early 80s (he was 2nd in the Boycott Games Trials). I knew he was doing race management these days; according to the post he's measuring courses as well. I seem to recall that he was the measurer for Bolder Boulder.
With Benji and Hugh Jones in the measurers' fold, we've got some pretty fast company.
