4. The period of Percy Cerutty, who found in Herb Elliot probably the most talented athlete ever (together Jim Ryun) for 1500m. Cerutty, not professional coach, practically ended to coach top runners after the retirement of Elliot, which happened in very unusual way : only 22, after winning Olympic Gold in Rome with the WR (in this, something as David Rudisha did in London in 800m).
Directly connected with Cerutty, but a little bit later, the history of Arthur Lydiard started.
He spoke about "Marathon training", avocating a large "Aerobic base" before going to the pecific quality. But really, this training can be good for every event, apart Marathon : nothing of specific for that event.
Lydiard had a great influence on all the coaches of the period, due to the successes of his athletes, and to the fact he was of English Language.
In Europe, during the same period, we had development of different schools, all connected with high mileage : in France with Frassinelli (Jazy ran sometimes 3 hours, starting every new season with very slow run), in Poland (with more intensity, producing top athletes as Jerzy Chromik and Krzystof Krzyszkowiak), in UK.
UK had a period with very high mileage, using winter, and the cross country season, as main motivation for developing qualities of endurance later used on track.
All the best athletes (also who later became a specialist of shorter distances) started in the school with long cross : Steve Ovett, Steve Cram (winning European Junior in Bydgoszcz '79 in 3000m), Seb Coe.
At the same time, they developed a system of CIRCUIT TRAINING looking at increasing of STRENGTH ENDURANCE, and this system was, later, used by North African athletes too, because is the best for 800-1500m (and also today, very little changed, and many changes made specific training worse in this direction...).
It was also the period of the great Portuguese runners : Fernando Mamede (WR holder of 10000m)and Carlos Lopes (winning of WCh in Cross Country, and Olympic Gold in the Marathon) followed, with different plans, the phylosophy of the great coach Moniz Pereira, who in my mind was the first lookin at the INTENSITY OF LONG INTERVALS.
5. A new period looking at higher intensity, WITH THE MISTAKE TO REDUCE DRAMATICALLY THE VOLUME. This was for making training more "comfortable" looking at the requests of new generations, which didn't have anymore the same will to use a lot of time for long run. But this fact, combined with the lack of general endurance due to a more sedentary type of life, REDUCED THE LEVEL OF RESULTS, and all the Western Countries (Europe, US and Oceania) went in the darkness, losing completing the clue of training.
