I wasn't a huge fan, but even I would damit that franz's contribution to coaching was on a par with lydiard, cerutty and Bowerman. He was the father of interval training.
Gerschler was using it at about the same time in the late 30's, but stampfl's efforts went unnoticed due to the war. I believe he was more of an advisor to Bannister and a coach to Chataway and Brasher. His realy strong efforts came with Merv Lincoln, Ralph doubell and later, Peter Bourke.
His athletes did both distance and intervals with 7-10 mile runs the norm during the season. He had a base period of distance like most, butfelt that the body was like a fine car, "you need to open up the throttle so that you can test the motor."
Doubell did workouts like:
50 x 200m 100 x 100m and 30 x 300m All with short intervals
for a 4 minute miler he suggested:
10 x 400 @70sec during the base period with 3 min recovery
6 x 800 @ 2:15 with 5 min recovery
4 x 1200 @3:35 with 10 min recovery
He would also use sprints (100-150) during the build-up and some fartlek work
As the athlete approached racing season, the 400's got down to 60 the 800 2:05 and the 1200 3:15
Final prep period saw the 400's under 60 and everything else at 4:00 pace.
He included weights right up to the major comp week
If you get the chance you must read of Lincoln's series of races with Elliott.
Hope this helps
