80/20 Running into Practice
I have been putting the 80/20 running rule into practice. The principal is simple. Instead of running to your max you run at a comfortable pace for most of your running instead. Instead of pushing yourself to be fast, you push yourself to have endurance. You train at a pace that is 80 percent or less of your maximum, to perform better when you race.
Train for Endurance, Not Speed The concept is rational.
