Featuring the proven 80/20 intensity balance described in Matt Fitzgerald's bestselling book 80/20 Running, this Marathon Level 1 training plan will provide you with the same workout structure used by the most successful runners in the world.

TARGET ATHLETE

This plan is appropriate for newer runners preparing for their first marathon, masters athletes, or 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 3 times per week for up to 6 miles or more.

INTENSITY TYPE : HEART RATE

This plan presents each workouts intensity target by Heart Rate, but Pace, Power and RPE versions of this plan are also available. All workouts are structured and can be exported to a supported device, which will 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.
