So, my goal here is to focus on the HOW, based on several years of training as a distance runner with my father as coach/advisor. He coined the term, now I am trying to put it into practice.

I will begin with the bottom line! Build a strong base (LIT, strength training, distance) then intensify (HIT and speed work).

Figure 1: My recommended pyramid of progression from base building to peaking

The base layer in the pyramid is a component of all distances from the 1500m to the marathon. It is your fundament, and it depends on health, fitness, and training ‘age’ (how long you have been running/specifically training).
