I just noticed an article that stated that Mihaly Igloi introduced Jogging half the distance of a repetition irrespective of what speed it was run in. It goes on to say that Igloi was the first coach to introduce training in sets. I found that those two features were an intricate part of his program.
I wanted to be a marathon runner. What I have in my log are the workouts I did. They do not represent the workouts of any other runner.
I often did 35 repetitions in one workout and there were weeks when I ran 3 or more hard workouts in a row.
All my running was on the grass. The repetitions were often on the track infield. Where I mention big laps I refer to a 657 yard oval which included 330 on the track infield. I often repeated 440s, 880s, 110 or 220.
Mon am 20 laps-5 easy then alternate 1 with 330 good swing then 1 with good speed
pm 10 laps, 10 shakeups-5 sets-1 of 10x260 good speed with 180 jog, 1 set of 5x660 good swing with 220 jog etc--2 laps between sets, 14 shakeups after (a 26 mile plus day in a 133 mile week)
This went on day after day. We ran twice a day except for Sunday.
An easy day consisted of 20 laps (7 miles) easy in the morning and an hour easy in the evening followed by 20 shake ups.
Putting this on paper does not do it justice. Coach knew how to administer the work on an increasing basis so that one could increase mileage and handle it mentally and physically. He watched all workouts and changed them as you completed sets usually only giving you your workout one setion at a time.
