Questions
How many weeks is this marathon plan?
20 weeks counting back from race day, 3 runs a week. Week 20 is race week.
How far is the longest run?
23.5 km (14.6 mi), reached in the peak phase before the taper begins.
How much will I run each week?
Between 20.5 km (12.7 mi) and 42.5 km (26.4 mi), with a lighter week roughly every fourth week.
Can I train for a marathon running only three days a week?
Yes. Three days is enough if one of them is a properly long run. Cross-training is optional and is not part of this plan.
What if I miss a workout?
Don't try to make it up. The MarathonPlan app moves the next week down by 15 percent after two or more missed workouts and never adds distance to catch up. The rules are public on the methodology page.
Is the plan free?
Yes. The full plan, every week, is free on this page and in the generator. The app subscription ($4.99 a month or $39.99 a year) adds the calendar, rescheduling and the adaptive rules.
