80/20 5K – Level 1

About the plan

9-week plan based on the 80/20 methodology for beginner runners preparing for their first 5K or for experienced athletes who prefer a lower-volume program. The 80/20 philosophy holds that roughly 80% of training should be done at low intensity (easy pace) and only 20% at moderate and high intensities. Studies show that this approach reduces injury risk and improves performance in a sustainable way.
