I'm not arguing against the results hart's program has produced. I am arguing against HS coaches using his program just like he uses it. The 200m tempo time is based on goal 200m time. If you have a 22s 200m runner his 8x200m day should be @30-31s not 28s. I went to a coaching conference last year where this coach actually suggested that sprinters at the HS level be started at 12×200 in 32s. I was sitting there shaking my head, I am sure they'll be able to finish it, but what happens when you get that down to 4x200m and 24s? That's too intense for a tempo day. It's more like a special endurance day, but even then the intensity may be too high. If you have a 20s 200m sprinter that 24s is fine, but for a 22s 200m guy its too much.
I agree as well. Sorry if it sounded like I was disagreeing with you. MOst high school coaches unfortunately don't adjust their workouts.
