The Extra Mile! What Is The 80% Rule In Running?

In this episode of RunPod, host Jenny Falconer introduces listeners to the transformative concept known as the 80% rule in running training. This rule posits that athletes should allocate approximately 80% of their running time to easy, conversational-paced runs, leaving only 20% for more intense training sessions.

Falconer explains that this method, aligned with polarized training principles, is effective even for elite runners, allowing them to improve their performance without the risk of fatigue or injury. By maintaining a relaxed running pace, runners can enhance their aerobic base and endurance, ensuring they have the energy required for their harder workouts later in the week.

Through this approach, runners are encouraged to have four easy runs if they train five times weekly and reserve the last session for harder efforts such as intervals, hills, or tempo runs. Falconer reassures listeners that easy running is not lazy—it is a strategic decision that plays a critical role in achieving faster and stronger outcomes. Therefore, by applying the 80% rule, runners can focus on consistent progress and improvements over time while preventing plateauing. Ultimately, the episode concludes with the motivational reminder that slowing down can lead to faster improvements.
