Arthur Lydiard - the great mid/distance coach from New Zealand back in the 50-60’s, who went touring the world teaching other nations how to keep up…
Here is a very limited shot
100 miles week off season
No La+ in off season base miles
99.9% of runs to be close to marathon pace (not long slow distance, but long fast miles…)
And the key - 5sec sprints to be done 1 x week
The result - back in the 60’s, on a grass track, a 1:44 800m - zero pacing.
The same guy - out kicked everybody over 800m, virtually undefeated over 800m
A 1:44 on grass - that’s comparable to the run at the last Olympics on the latest synthetic tracks. And how fast is Rudisha!!
