Overview

Already run a marathon? This plan is designed to make your next one faster. It focuses on VO2max intervals, lactate threshold runs, and race-specific long runs.

Prerequisites: You should have completed at least one marathon and be running 40+ km per week consistently.

2	5 × 1 km @ 5K pace, 2.5 min rest	8 km easy + core	9 km tempo	24 km easy	~53 km
3	4 × 1.2 km @ 10K pace, 2 min rest	9 km easy + core	10 km tempo	26 km w/ last 6 km at MP	~57 km

MP = Marathon Pace. Mon, Fri, Sun are rest or very easy recovery days.

Key Workouts Explained

Workout	Purpose	Effort Level
VO2max Intervals (800m–1.2km)	Improves oxygen processing ability	Hard — 5K race effort
Tempo Runs	Raises lactate threshold	Comfortably hard — 15K to half marathon effort
Marathon Pace Long Runs	Teaches your body and mind to run at goal pace	Moderate — should feel controlled
Recovery Weeks (4, 8)	Allows adaptation and prevents overtraining	Easy — embrace the rest
