Free Half Marathon Training Plans

Running a half marathon has become a very popular running goal as 13.1 miles is a great distance for anyone–from beginner to advanced runners to tackle! So I’m excited to help you with your half marathon goals! I’m going to do this by giving you access to my 12-week free half marathon training plans (below) from the couch to half marathon and intermediate levels.

I love the half marathon because it is a challenging and satisfying distance, yet it doesn’t require you to overhaul your entire life. And, honestly, it doesn’t hurt as much as a full marathon. After a half marathon, you may be a little bit sore but not so sore that you can’t sit down without holding onto something to brace yourself (like with a marathon).

If you chose the right half marathon training plan, you will get fitter, reduce your risk of injury, and set yourself up to tackle even bigger running goals (such as the marathon distance — or not!). 

So, let’s get started!

How long is a half marathon?

A half marathon is 13.1 miles or 21.1 kilometers. A half marathon is half the distance of a marathon which is 26.2 miles or 42.2 kilometers.

How long does it take to train for a half marathon?

It takes 12 weeks to train for a half marathon. Most people need at least 3 months to train for a half marathon safely to gradually grow your longer runs. This timeframe allows for your body to adapt physiologically to the impact of running and to develop the adaptations necessary to run 13.1 miles.

Some of these physiological adaptations from half marathon training include:

  • pushing your lactate threshold;
  • increasing capillary density and mitochondria production;
  • improving cardiac stroke volume;
  • increasing glycogen storage (for fuel/energy);
  • strengthening muscles, bones, ligaments, and tendons;
  • bettering muscle activation and neuromuscular coordination.

If you have been running and have base mileage, you can run a half marathon in less time.

However, if you are going for a personal record in the half marathon or have a specific time goal, then you will need about three months to train for a half marathon to optimize these physiological changes.

What makes a good half marathon training plan?

Most half marathon training plans will include at least 2-3 easy run days, 1 long run day, 1-2 complete rest days, 1-2 cross-training days, and maybe one speed day.

More advanced half-marathon training plans will include 2 long runs and 2-3 speed work days.

How do you train for a half marathon?

You should train for a half marathon by running at least one long run a week.

Long runs are the bread and butter of half marathon training because they teach the body how to endure running for longer time spans. It spurs those biological changes that allow your body to optimize energy production and use, and your mind to keep running even when you’re tried.

Long runs should be done at an easy pace. This is a pace in which you can hold a conversation and when you’re done running, you feel like you could keep going. You should not be exhausted at the end of a long run. If you are, you ran too fast!

Your heart rate will likely be in the 140s and your rate of perceived effort (how hard you run) is a 6 out of 10.

How do I find the right half marathon training plan?

To find the right half marathon training plan you need to first look at your running history and time you have. Then, you need to ensure the training plan progresses your mileage carefully, has rest days, at least one long run day, and cross-training days.

When doing your self-evaluation to pick your half-marathon training plan, look at:

  • Your background: How much have you run in the past? How much are you running now? What has been your peak mileage? Do you suffer from running injuries?
  • Your training response: How has past training felt like? Do you handle mileage well? Do you like to run speedwork? Do you need extra cross-training days?
  • Your ability: How fast is your pace? How long does it take you to do long runs? (if you are a slower runner, you will need a training plan that schedules runs by time rather than distance, for example)
  • Your schedule: How much time will you have to train daily? Will you get enough sleep with your training? Will you have time to recover after your long runs and workouts?

Sample Half Marathon Training Schedule

Here is week 7 of my 3-month half marathon training plan for intermediate runners.

The biggest differences between my beginner half-marathon training plan or couch to half marathon training plan is the absence of speedwork and less mileage.

  • Monday: Run 5 miles, 4 strides
  • Tuesday: warm-up, 30-minute tempo run, 1 min easy, cool-down
  • Wednesday: Run 6 miles
  • Thursday: 1-2 mile warm-up, 4 by 800 meters at comfortably hard pace (RPE 8), 1-2 mile cool-down
  • Friday: Cross-train or walk for 1 hour
  • Saturday: Run 10 miles easy
  • Sunday: TOTAL REST
