Thanks for your comments KK. I have a 400m runner who I think will benefit from your model. I am concerned he will not be able to handle the volume of longer SE runs, such as the 300 250 etc workouts. From past training, 300+150 may be all he can handle. What are your thoughts on this?
Also, from what PJ reported from Jamaica, it seems Bolt a month ago was doing a (300 180 120 ) x 2. I found it interesting to see this, and then noticed your program, which is where my idea came from. Maybe a shorter sprinter doesn’t need all the reps, but a 400m does to improve the last 100, as you describe.
From your female who later made the 4x1 team, do you recall what her time drop was for the year? Having not used your program, and knowing my guy will need a drop in 100m time, I’m curious as to what potential it may have.
