The Pi(e) Day workout is all about pace differentiation and giving just a little bit more. Start with either a your half marathon or 10k pace for a 1200m; finishing your third lap with an extra .1415926 of a lap (obviously, it depends on where you start, but this will be just over halfway around the curve if you just finished on a straightaway).

Next up, progress to a set of 800’s at 10k or 5k pace (one notch faster than your 1200m). Take a 1:30-2:00 rest in between each 800. Add .1415926 of a lap to the 3rd 800.

After your brief recovery from the 800s, crank up your pace a little more for some 400’s! Suggested recovery time between 400s is 1:30. Add .1415926 of a lap to the 3rd 400.
