This article and training plan was written by expert running coach, Greg McMillan, from McMillan Running.

The thrill of crossing the finish line with 26.2 miles behind you is a bucket list goal for many, and there is no doubt that running a marathon is a monumental accomplishment. However, tackling a marathon or ultramarathon is a physical and mental test that should not be taken lightly. You'll need to prepare and you need a plan that will not only have you crushing your goals, but one that incorporates cross-training such as rowing, yoga, and mobility, as well as rest, so that you stay healthy and injury free.

How Long Does it Take to Train for a Marathon?

There's no reason to sugarcoat it—running a marathon is hard on you physically and mentally. That is why I am a proponent of easing into training and incorporating cross-training into your weekly regimen. I have been lucky to coach thousands of runners, and because of that, I have figured out a solid 12-week plan that allows runners to adequately prepare while also keeping their minds and bodies happy and healthy.

This three-month plan allows novice and moderate runners to fit training into their daily lives. By committing to a 120-day plan, I have found that runners are not worn down by race day, but it also provides plenty of workouts that will simulate the type of fatigue that they will face on race day.

Why You Should Follow a Marathon Training Plan

The very nature of a marathon means that there are going to be a slew of unknowns. However, by following this training plan, runners are able to gradually yet progressively build their ability to match the demands of whatever race days throw at them. Training plans will leave runners feeling confident that they have enough endurance, stamina, strength, and speed to eat up 26.2 miles. Furthermore, a proper training plan exposes runners to the mental challenges that they will face when undertaking a marathon. If people stick to their training plan, race day becomes more like being on autopilot rather than worrying about the nuances and challenges of a particular course.

The Marathon Training Plan - Know the Lingo

It is important for runners of all levels to stick to training plans, and that includes getting familiar with some of the jargon and learning how to evaluate your progress.

  • Cross-training: Cross-training incorporates a variety of other exercises, such as yoga, rowing, resistance training, and mobility, into your weekly plan. Cross-training increases your overall fitness, trains other muscle groups, and helps reduce injury. It is important to not skip these days.
  • Steady-state run: When running at a steady state you will keep a continuous easy-medium pace.
  • Intervals: Although your ultimate goal with this plan is to crush a marathon course, intervals will play an integral part in getting you there. Intervals are short, intense runs that are repeated several times. There are small breaks between each interval.
  • Tempo run: Tempo runs are also called "threshold runs" because you run at a pace slightly below your current marathon threshold pace—approximately 25-30 seconds per mile slower. They help your body learn to run at a harder pace for longer.
  • Rest days: Just as our bodies need exercise, they also need rest. Rest days allow our muscles to restore and rejuvenate. They also help keep us from burning out during our training.
  • Down week: Down weeks consist of running less mileage than the weeks leading up to them. They can help you stay healthy and energized for an upcoming race. Like rest days, it is critical to adhere to your schedule for down weeks.
  • Progression run: Progression runs start a slow, comfortable pace and then build to a faster pace at the end.
  • Goal pace: Once deciding on your goal finish time for your marathon, you can gauge the average pace that you will need to run each mile to meet that goal.
  • 3rds progression run: On these runs, you will break them down into thirds. The first third will be a slow, comfortable pace. During the second third, you will increase to a steady running pace, and the third will be done at a strong, fast pace.
  • Yasso 800s: By utilizing Yasso 800s, a series of 10 fast 800-meter intervals alternated with short rest periods, you will feel the effort and speed of running a marathon at your goal pace.
