Yes, they sure do. I know a girl who ran for a well known University in Texas. The coach made the girls team run so many 600s through the whole year it was sick.
As I was told from this girl the head coach does not believe in pure speed work and only uses SE2 type workouts as there meat and potatoes. As a matter or fact her old HS coach got into a small argument with the coach at the university because he said the university would see better performance if this girl would do some speed work but it never happened.
Anyhow, I remember being on the phone with this girl and she would be crying because practice was so hard but she had to put herself through it because she was on scholarship. She ran about a 53-55 sec 400.
I have been under a coach like this myself but not as bad as her. Anyhow, I’m now on Charlies program and ONE of the MANY things that is awesome about his design is that you feel fresh every time you step on the track for a workout and you WANT to give it your all instead of arming yourself up just to get through practice; there is a difference.
