I completely agree with that Nobby.
When Lydiard first came to the US, most people were interval-trained. He told them that his runners did 100 miles a week of training. Some people tried it but, because they weren't as well-conditioned as his runners, did it slow (just to survive). They figured running this slow would not make you a fast competitor. So Lydiard training is no good. For decades, Lydiard had to fight against such thinking by telling them also that "Snell and Davies did 20X400 in 60 seconds or faster. How much speed to you need?"
Marathon conditioning, or aerobic base building phase, is merely prerequisit to more exacting training phases. Because his runners were so much stronger than others from all the miles that they ran, they could do much more faster or more race specific training than other runners. This is the whole principles of the Lydiard program that has been applied to other sports like rugby or kayaking--those who have developed their stamina can do more competition-specific training than others. While others might practice "passing of the rugby ball while running as fast as you can" 20 times, if you developed adequate stamina, you do that 40 times.
I think one of the main reasons why Lydiard is misrepresented is because he was reacting against the extreme interval training of the late 50's by Zatopek and Pirie. They took Gershler's ideas to the extreme and it was their downfall after their amazing initial success.
So people thought that Arthur was anti interval training, when in fact he was just trying to make more sense of what works and what is too much.
