You are correct, and if oyu analyze all the bad advice RW gave out, it basically told people not to do recovery runs. Their advice was geared towards the average working people who did not want to dedicate themselves to running. They did some short, hard workouts, other stuff, not the easy days a real runner would take, and they were socialble at their races.
It expanded into the high school world (from the parents) and, lo and behold, we were running lower mileage.
I realize that there are many ways to train- some with high mileage, some wihtout. but I really don't think anyone will be competitive internationally on low mielage. The best runners simply run alot.
