Remember, many successful programs are arranged to follow a weekly pattern:
1: Speed
Speed Endurance
Off

Sometimes, coaches who think their athletes are “behind” will use the four
high intensity day schedule. And while this can be quite dangerous, when
monitored closely, an athlete may receive some gains from this more intensive
schedule. The mesocycle with a four high intensity day schedule would most
likely have to follow the 2-1 work-recovery scheme, or the athlete would be
substantially overloaded with high intensity work.
