My experience based on various Europeans who trained in Phoenix in the mid-80's to early 90's [including Markus Ryffel ('84 OG 5000 silver medalist), Dietmar Millonig, Stephane Franke, Dieter Baumann (yes, he's now discredited, but from what I saw, he trained smart)] is that they trained a lot like what JK talks about... very little anaerobic repetition work, and a lot of high end aerobic stuff. Their fartlek runs were very rhythmic, with "float" sections at a fast road pace and "hard" sections that appeared to be right around LT pace, or slightly faster. Their sprint work was usually very short - 200's or shorter. Sound familiar? Read 'Summer of Malmo' or JK.
At various occasions (they weren't necessarliy in town concurrently) some European elite runner would say to my coach, "your runners train too hard," or "Americans train too hard." I think they were referring to our cultural propensity to hammer out anaerobic stuff, like repeat 400's, year-round.
