At the University I workout at I have never seen one rep of what we would all call speed work. Of course I haven’t seen all of their running workouts but at least 3x per week for most of the year I see them training. They do the sprint the width of the field as position group thing and then back again after the other groups go. That would be tempo type training really. They do some agility drills with decent rest that would qualify as true high CNS work.
