After you’ve completed your warm-up you will run 800 meters at a Zone 4 effort. This will likely be faster than the pace you typically run at on a daily basis.


After the first 800 meter rep, you will recover with a slow run or jog in Zone 2 for 400 meters or approximately 2-3 minutes. After the 400 meter recovery period you will then perform another 800 meter hard effort in Zone 4. You will repeat this process a total of 4 times for 4 x 800m at a hard effort in Zone 4.


The goal of this workout is to take you out of your comfort zone and push yourself to build strength, power and endurance.
