Training for your first, fifth, or even 50th half-marathon is always exciting. The distance strikes a perfect balance: it’s long enough to feel like a major accomplishment when you cross the finish line, yet manageable for most runners balancing training with work, family, and other responsibilities.
That said, running a successful half-marathon doesn’t happen by accident. It requires consistent training, smart pacing, proper fueling, and a thoughtful race-day strategy.
Whether your goal is simply to finish, set a personal best, or enjoy the experience from start to finish, preparing the right way can make all the difference.
To help you get there, our expert coaches have compiled their best tips for half-marathon training—from building your weekly mileage and structuring workouts to dialing in your race-day plan.
Follow these strategies, and you’ll give yourself the best chance of reaching the finish line feeling strong, confident, and ready to sign up for the next one.

#1: Choose an Appropriate Half-Marathon Training Plan
Among the many hundreds of online half-marathon training plans you will find, there will be a bit of a range in the number of days per week you run and a variety in the training sessions you will perform.
The more aggressive the training plan, the more frequently you run per week, and the higher your training volume (weekly mileage) will be.
Here are our most popular free half marathon training plans:
- 8 Week Half Marathon Training Plan – a compact plan for runners with a solid base
- 12 Week Half Marathon Training Plan – the most popular option for most runners
- 1:45 Half Marathon Training Plan – a goal-specific plan to break 1 hour 45 minutes
- 1:30 Half Marathon Training Plan – for experienced runners targeting a fast time
For example, beginner half-marathon training plans require only three running workouts per week, while advanced or intermediate plans often require six.
In addition, some beginner training programs will focus all their weeks leading up to the race on easy runs, while others, more advanced, will include speed work, threshold runs, fartleks, and race-pace runs.
When choosing the best half-marathon training plan for you, consider your experience level, injury history, and your life schedule.
Some runners can realistically run only three to four days per week due to work or family commitments, while others have no problem with six running days.
If you have a history of getting injured when you run too much, or you have some type of chronic injury that flares up with high mileage, you should look for a training program that is not only more gradual and conservative with plenty of recovery days but also relies on cross-training days to substitute for some of the base-building aerobic training runs.
If you have only been averaging 15 miles per week, you wouldn’t want to jump into a half-marathon training plan that has you starting at 25-30 miles per week or training for a half-marathon in six weeks.
Be honest and realistic about your current fitness level, the time you have available to train, your body’s health, and the types of workouts and training volume you can handle.
How Long Does It Take To Train For A Half Marathon?
Most runners with a decent fitness level can train for a half-marathon in 12 weeks or three months.
Beginners can expect to spend at least 16 to 20 weeks training for a half-marathon (though it’s best to have six months of running under your belt) if you are just getting started on your running journey.
Advanced runners may be able to train for a half-marathon with a 6-8-week plan, depending on their fitness level and goals.
#2: Vary Your Runs
Although when you are just trying to finish your first half-marathon, the majority of your workouts will involve building your endurance rather than working specifically on your speed, steady-state running is, perhaps surprisingly, only part of the training that you should be doing.
It is also important that interval workouts, hill runs, threshold workouts, and runs with bouts of half-marathon pace are part of your training plan.
This variety is necessary to develop all aspects of your fitness and get your body comfortable running harder and faster so that half-marathon pace is physically and mentally sustainable.
#3: Cross Train
Another important type of workout in good half-marathon training plans is cross-training.
Running is a high-impact activity, so if you do too much running too quickly and progress your distance too aggressively, you run the risk of injuries.1de Jonge, J., Balk, Y., & Taris, T. (2020). Mental Recovery and Running-Related Injuries in Recreational Runners: The Moderating Role of Passion for Running. International Journal of Environmental Research and Public Health, 17(3), 1044. https://doi.org/10.3390/ijerph17031044
Cross-training refers to any exercise other than running, but it is best to focus on low-impact cardio, such as indoor or outdoor cycling, swimming, deep-water running, or using the elliptical machine.
The primary purpose of cross-training workouts is to improve aerobic fitness while reducing the impact of running on bones, joints, muscles, and connective tissues.
#4: Take Rest Days
Although you may want to run every day, it is very important to take the prescribed rest days and keep the runs capped at the time or distance suggested by the schedule to prevent overdoing it.
#5: Don’t Neglect Mobility Work
Although recovery modalities such as stretching and mobility work are not specifically listed on most half-marathon training plans, they should absolutely be part of your workout routine.
Dynamic stretches before you run, such as walking lunges and hip swings, will help warm up your muscles and prime them for the next workout.
Foam roll the major muscles in your lower body, such as the hamstrings, quads, calves, and glutes. Using the foam roller on the outside of your leg can also be helpful along your IT band.
#6: Nutrition Is Key
The other important component of half marathon training is nutrition.
In terms of your nutrition, you are now a runner, so you need to treat your body as if you are an athlete in training; after all, you are.
Focus on nutrient-dense, whole, natural, unprocessed foods like vegetables, lean proteins, fruits, whole grains, seeds, nuts, eggs, legumes, and low-fat dairy.
Be sure you eat enough carbohydrates. Carbs are essential for replenishing glycogen stores and providing the energy you need for each workout.
You will also need to practice your in-race nutrition strategy by using gels or any other energy product you would like to use.
Also, ensure your hydration is on point by consuming enough fluid and electrolytes throughout the day.
#7: Strength Train
One of my best training tips as a coach is to add core exercises and strength training workouts to your training plan two times per week.
Studies2Vikmoen, O., Rønnestad, B. R., Ellefsen, S., & Raastad, T. (2017). Heavy strength training improves running and cycling performance following prolonged submaximal work in well-trained female athletes. Physiological Reports, 5(5), e13149. https://doi.org/10.14814/phy2.13149 have also shown that strength training workouts for runners can improve aerobic capacity (VO2 max) and submaximal endurance performance due to resulting neuromuscular adaptations.
Even if you don’t have a gym membership or any strength training equipment, you can do bodyweight exercises such as squats, lunges, push-ups, planks, bridges, tricep dips, and other exercises for your abs, hips, and lower-back muscles.
#8: Set a Reasonable Goal
One of the most important parts of preparing for a half-marathon is setting a realistic and meaningful goal.
If you’re running your first half-marathon, your primary goal should simply be to finish the race. Completing 13.1 miles is a major achievement in itself, and focusing on finishing strong will help you enjoy the experience rather than feeling pressured by a specific time.
If you’ve run a half-marathon before and want to improve your time, aim for progress that matches your current experience and fitness level.
Runners who are relatively new to the distance often see larger improvements between races, especially if they follow a structured training cycle and execute a smart pacing strategy on race day.
Early in your running journey, fitness tends to improve quickly, and you also gain valuable experience with pacing, fueling, and race strategy.
Because the half-marathon is a long race, these factors can make a big difference. It’s common for runners to perform noticeably better in their second or third race, even if their training hasn’t changed dramatically, simply because they’ve learned how to manage the distance.
However, runners who have been training and racing half marathons for several years often see smaller, more incremental improvements as they get closer to their potential. For example, if your progression has looked like this:
2:01 → 1:53 → 1:51 → 1:50 → 1:49 → 1:48 → 1:45
Expecting to suddenly jump to 1:38 in your next race may be unrealistic.
A more effective approach is to chip away gradually, targeting small improvements of one to three minutes per race while continuing to refine your training, pacing, and race-day strategy. Over time, those incremental gains can add up to significant progress.
#9: Have Fun
Even if you’re training seriously for a half-marathon, it’s important not to lose sight of the joy that brought you to running in the first place. Training should enhance your life, not feel like another stressful obligation.
Look for ways to keep the experience enjoyable throughout your training cycle. This might mean running with friends, exploring new routes, listening to your favorite music or podcasts, or signing up for a race that supports a cause that’s meaningful to you.
Staying connected to the fun side of running can help keep you motivated, consistent, and mentally fresh—making the entire journey to race day just as rewarding as crossing the finish line.
