Rich Elliott (4:10 HS miler back in the 1970s) did a piece last year in Running Times entitled "Out of Hungary." It detailed Igloi's influence on American distance running. Elliott's college coach was Bob Timmons at Kansas University also Jim Ryun's coach. From my experience one of the better pieces on Coach Igloi. After the article appeared I called his son Tomas and he purchased as many copies he could find for the extended family in the Hawthorne, Caliornia area. Tomas Igloi was very successful as a mechanical engineer with patents for airplane flight control systems.
In my own experience, we ran 13 sessions a week, 2-a-days Monday thru Saturday, and once Sunday morning. We had Christmas, Easter and a week in August off. We had a 3/4 mile and 440 time trial New Years Day. I went from a 4:50 mile as a high school junior to 14:04 three mile as a sophomore.
He would coach anyone.
