Workout Detail: The jog pace is programmed to be at an “active recovery” or “conversational” pace. The remaining intervals are intended to be fast and consistently paced from distance to distance. Remember…the intensity for these intervals must be fast. Helpful hint on “fast” is equal to or slightly slower (1sec/100m) than your 1 mile PR pace.

Workout Focus: Force recovery during the active jog recovery.
