80/20 Half Marathon – Level 1

About the plan

15-week plan based on the 80/20 methodology for beginner runners preparing for their first half marathon or for experienced athletes who prefer a lower-volume program. The half marathon requires complete preparation: the 13.1-mile (21 km) distance demands a solid endurance base, but it is also short enough to be run at a relatively strong pace. That calls for work on both endurance and fatigue resistance at high intensity. This plan develops both qualities progressively and safely.
