Plan Description


Meticulously crafted from the principles laid out in Matt Fitzgerald's best-selling book 80/20 Running, this Marathon Level 1 training plan will provide the athlete with the same workout structure used by the most successful runners in the world. Each week, cycle, and the complete 18-week plan has been specifically formulated to match the research articulated in Fitzgerald's publications and ensures the runner adheres to the 80/20 principle.

Target Athlete


This plan is appropriate for newer runners preparing for their first marathon and for more experienced runners who need or prefer a relatively low-volume training program. Before you begin the plan, build your training to the point where you are running at least three times per week for up to 6 miles or more.

100% Structured Workouts


This plan leverages the TrainingPeaks.com structured workout feature with heart-rate based workouts. On supported devices, including many Garmin models, each workout can be exported to the device, which will automatically guide you through the session with duration, lap, and intensity prompts. Workouts do not have to be exported to be performed effectively, as the detailed descriptions provide all the information you need to successfully complete the workout. See our Structured Workout page for more information.

Level Guarantee


Not sure which level is right for you? Each 80/20 plan comes with a Level Guarantee: if you discover that the level you have selected is too hard or too easy for you, simply contact us for a complimentary switch to a different level within the same distance category.

Support


Robust support resources and documentation for your plan, including zone guidelines, can be found at the 80/20 Resources page. Purchasers of this plan will be able to contact the authors Matt Fitzgerald and David Warden directly in order to request clarification on any items that may be unclear in the plan.
