The only example i have is myself. I was trained by my nimrod coaches at my high school last year, and all we focused on was short distances and that was it. It didnt click in until regionals where i had no gas in the tank after competing in the TJ finals.I believe that you should always focus on speed. The special endurance would undulate based on their race distance and previous training. Can you give us an example of an athlete? That way we can get more detailed.
For this year i would like to include some special endurance. along with the hurdle workouts. The first step is getting the book training for speed.
I have thrived off of this crappy program for 2 years but doubt im going to see more improvements.
