80/20 Marathon – Level 1

About the plan

18-week plan based on the 80/20 methodology for beginner runners preparing for their first marathon or for experienced athletes who prefer a lower-volume program. The marathon is a distance that demands a very high level of endurance and the ability to run hard even when fatigued. About 75% of the participants in any marathon — elite runners included — hit "the wall" in the final miles. This plan was designed to minimize the chances of losing pace after mile 20 (km 32), progressively building aerobic endurance and fatigue tolerance.
