Featuring the proven 80/20 intensity balance described in Matt Fitzgerald's bestselling book 80/20 Running, this Marathon Level 0 training plan will provide you with the same workout structure used by the most successful runners in the world.
TARGET ATHLETE
This level is intended for athletes without a running background attempting their first marathon event. You should be able to comfortably run for at least 30 minutes before you start the plan.
INTENSITY TYPE: HEART RATE
This plan presents each workout's intensity target by Heart Rate, but Power, Pace and RPE versions are also available. All workouts are structured and can be exported to a supported device to automatically guide you through the session with duration, lap, and intensity prompts. See our Structured Workout page for more information.
BASED ON THE OPTIMAL 80/20 INTENSITY
The difference with an 80/20 Endurance plan is balance. Our plans are based on the 80 percent easy/20 percent hard formula practiced by elite athletes and proven to work better for athletes of all abilities, as presented in our best-selling 80/20 training books.

WHAT 80/20 ATHLETES SAY ABOUT OUR TRAINING PLANS

LOOKING FOR UNLIMITED ACCESS TO OUR PLANS, COACH SUPPORT and MORE?

80/20 Endurance is the creation of Matt Fitzgerald and David Warden. Based on the breakthrough books 80/20 Running and 80/20 Triathlon, runners, triathletes, and other endurance athletes improve the most when they consistently do 80 percent of their training at low intensity and the other 20 percent high intensity. The typical endurance athlete spends only 50-70 percent their total training time at low intensity. The solution? An 80/20 training plan that ensures the optimal intensity balance.
