Certainly, we have far more knowledge today than when Lydiard was, through trial and error, developing his training program. But, it can't be denied that he got a ton of things right.
: He insisted that his athletes build up a large aerobic base before embarking upon harder, more anaerobic (glycolytic)
training. And, to his credit, this base (as he called it, marathon training), was NOT just a lot of easy running. During
base training his runners did tempo runs (near marathon pace) twice weekly, and short, quick alactic sprints. So, contrary
to what many believe, Lydiard did not advocate just long slow distance at any point in his training plans.
: He was a pioneer of plyometric training (hill bounding)
: Mileage Matters: His runners did far more mileage than others of his day, but not more than current middle/long distance
stars perform. He was ahead of his time.
: His program was far more long-term focused, more sustainable, and more humane than the hard interval focused
programs that had previously dominated world-class training.
Yes, Lydiard could be very set in his ways, but there was no one more influential in the way the world's best middle/long distance runners train today. No one.
