yes u are right about that. some fast 600ms and some longer runs are needed for the 800m I believe.
This program however seem to fit more to super fast athletes that lack the endurance, than slower runners with good endurance. (as many have stated here) But cant say for sure. have never tried the program. The miler types will probably think the volume and intensity of the tempos are too little and slow, while the pure 200m type will probably hate and suffer during the tempo workouts :)But probably achive the best results from this program
