Not 100 per cent accurate.
You don't flip a switch to go from 100 miles per week of easy, steady, strong running to suddenly bounding up steep hills every day. And the same with going into the anaerobic phase.
Weekly fartleks in base keeps one from going anaerobic because they are done by feel, while staying in touch with speed and effort. Alactic strides for form and activating the neuromusclar system. And running over hilly environments during base phase is...well....hilly.
The hill phase also includes standard-style hill repetitions with a rectangle circuit, for ups, downs and recovery sections and strides sections. You can change the name of the phases, but Lydiard training is still Lydiard training. I get a kick out of coaches who say they know the Lydiard way and I talk to them for a while, and they have the basics, but get stuff quite wrong. Arthur said, "good and bad training can look the same on paper."
I was at a coaching conference several years ago. James Li from Arizona (Lawli Lalang and a few other athletes of note) got up and said, "I coach the Arthur Lydiard way." He wasn't prompted, he just said it. Then Alberto Salazar gets up after him and says, "I too coach the Arthur Lydiard way."
The two presentations were opposite in nature. And what I do know about them, use completely different approaches.
Neither in my mind coach the Arthur Lydiard Way, Salazar has a focus on too much fine quality and Li seemed rather apathetic about what Lalang was up to half the time. Had him run 60 miles per week, didn't know if he went off with some friends for a run half the time.
If it is true that Salazar was microdosing his studs and studettes, it makes sense that they hit it really well some of the time and were injured often and then when he was banned, most of them fell off completely.
