Last Updated:

If you’ve already run a 10k race and now you want to step up to a half marathon, you’re in the right place because this article will provide you with a 10k to half marathon training plan that will help you step up to the longer race distance.

This training plan is designed to be completed over 3 months, that’s all it should take for you to easily step up from 10k to a half marathon. This is an intermediate training plan for people who want a moderate volume of training without taking up too much time, and have the goal of finishing races feeling strong but not getting every last second of performance possible.

This half marathon program is adapted from the training plans in our app that are written by coaches who know exactly what it takes for amateur age group runners to overcome challenges and reach their endurance race goals.

To start this plan confidently you should at least be able to run continuously for at least 60 minutes, and be comfortable with running fast intervals.

Training Tips to Successfully Train for a Half Marathon

Before diving into the training plan we need to provide some half marathon training tips that will help you prepare for the race successfully, while avoiding a lot of the pitfalls that runners encounter.

How Long is a Half Marathon: The first place to start is by answering the question, “How many miles is a half marathon?” and “How many kilometers is a half marathon?” for our metric friends around the world. A half marathon is 13.1 miles which is 21.1 kilometers. But what is an average half marathon finish time? Enter your age and gender into the calculator below to find out what’s a good finish time in the half marathon for your age group.

‍

How Much Do You Need to Train for a Half Marathon: Knowing your weekly mileage (how many miles per week you should run in training) depends on your race distance, your athletic background, and your goals. It’ll take more training if you don’t have any endurance sports background and you want to win a marathon than if you’re previously an elite endurance athlete who just wants to finish a 5k. Use the calculator below to get a sense of our recommended training time and miles a week required to meet your goals.

‍

What Gear Do You Need to Train for a Half Marathon: There are two items that we recommend all runners have to prepare for a half marathon: proper running shoes and a strap based heart rate monitor. Here’s a video about what to look for in running shoes, and here’s an article on everything you need to know about heart rate training zones and why we use them.

Heart Rate Training Zones for Running: Low intensity running should always be dictated by heart rate, and not pace. This may mean that your easy run training is quite slow, but that’s ok because it’ll mean that you’re building endurance without a lot of physical stress. Calculate your heart rate training zones with this calculator.

‍

Half-Marathon Training Paces: Interval running workouts, also known as “speed work”, should be done using pace as opposed to heart rate. Pace is better than heart rate for intense runs because heart rate will lag by 60-120 seconds while your running pace is instant. Use this calculator to calculate your run training pace per mile and kilometer.

‍

Low Intensity Running: Our training plans are based on the pyramidal model of training(similar to polarized training, 80/20 running, and the Maffetone Method, but with improvements) where 70-80% of the training is done at low intensity Zone 1 and 2. Studies have shown that all athletes will perform better when performing the bulk of their training at a low intensity, it may be difficult to run in Zone 2, but you’ll perform much better if you train at a low intensity.

What to Eat When Training for a Half Marathon: what you eat before running, during your training runs, during your half marathon, and what you take for hydration will make the workouts you perform so much more effective. Physiologists we’ve worked with believe that proper nutrition and hydration can generate the same race results with half the training. This article discusses what to eat before your runs, and this article explains what you should eat during running workouts and races.

Check out the example workout below from one of our marathon training plans. You can see that every workout in our app comes with personalized nutrition guidance for your pre and during workout nutrition to maximize the workout effectiveness.

‍

Rest & Recovery: Your training plan will have complete rest days. Also, every third or fourth week will be a rest week with reduced training hours. It’s critical that you take these as days to truly rest and recover. If you do a pile of heavy yard work, or spend the recovery days on your feet walking around a mall, you won’t be resting and you won’t actually be improving from your training.

Remember that WORKOUTS + REST = PROGRESS, so take rest days seriously to make sure you avoid overtraining and actually progress in your training.

Taper Week: The training plan will have a taper period in the week prior to race day where training volumes will be reduced by roughly 50-60%, while some intense bursts of speed will be maintained. This process will allow your body to flush out all the training fatigue, and have lots of energy in the race. Take the taper process seriously, resting and sleeping as much as possible during taper week.

Half Marathon Race Pace: Workouts in a good training plan will have race pace intervals where you’ll develop the ability to run fast without getting tired. You can use the calculator below to calculate your approximate half marathon race pace for these intervals.

5 Key Differences Going from 10k to Half Marathon Running

Training for a half marathon introduces several new challenges compared to preparing for a 10k race. Understanding these differences is crucial for adapting your training plan and race strategy to effectively tackle the longer distance. The key distinctions include:

Race day nutrition
Pacing strategies
The need for longer long runs
The increased importance of strength training
Adjusting to longer taper and recovery periods

Each of these aspects plays a pivotal role in transitioning from a 10k to a half marathon, and we'll explore them in detail to help you prepare effectively.

Athletes approaching the starting line at the Bay Bridge Half Marathon in California.

1. Half Marathon Race Nutrition

For a 10k race, nutrition during the race is rarely a concern because the event usually lasts less than 75 minutes, which is typically the threshold at which athletes need to consider in-race nutrition. However, half marathons last longer, demanding a strategic approach to nutrition to maintain energy levels throughout. It's essential to plan your intake of fluids and energy gels or bars to sustain performance, especially after the 75-minute mark. This strategy ensures that you don't hit a wall mid-race, helping you maintain a steady pace to the finish line.

2. Half Marathon Pacing

Pacing in a half marathon is more critical than in a 10k. While a poorly paced 10k can still enabling runners to push through to the finish, a pacing mistake in a half marathon can be much more punishing. You might find yourself walking or significantly slowing down in the later stages. Successful half marathon pacing usually involves holding back considerably during the first quarter of the race and continuing to manage your effort through the middle part. This conservative start allows you to conserve energy, so you can maintain your pace in the final miles when it counts most.

3. The Need for Longer Long Runs

When preparing for a half marathon, the length of your long runs is crucial. These runs are key to building the endurance necessary to cover 13.1 miles comfortably. Typically, your long runs should start in the range of 7-10 miles and gradually increase to 15-17 miles. This progression not only boosts your physical endurance but also prepares your mind for the prolonged effort required on race day, ensuring your body can withstand the distance without breaking down.

4. The Increased Importance of Strength Training

While the impact of a 10k race on your body is manageable, a half marathon's longer distance demands more from your muscles and joints. Without adequate strength training, your body is likely to encounter issues, from injuries to energy inefficiency, where your movement becomes less about propelling forward and more about just staying upright. Integrating strength training into your routine leads to better energy conservation and a stronger finish, keeping you robust and efficient throughout the race.

5. Longer Taper and Recovery Periods

The preparation and recovery times for a half marathon are significantly longer than those for a 10k. A typical taper period for a half marathon might last about a week to ensure your body is well-rested and primed for race day, compared to just 2-4 days for a 10k. Similarly, recovery from a half marathon can take up to a week, reflecting the greater physical toll compared to the 1-3 days it might take to recover from a 10k. Adjusting your taper and recovery schedules is essential to perform your best and avoid injury.

The Best Half Marathon Training Plan for Every Runner

Our run training plans are written by the excellent coaches at Run Free Training who know what it takes to help amateur athletes reach their goals. While the coaches are elite runners themselves, they have a great understanding of how to create training plans that are time efficient and overcome the obstacles most age group runners face in their training.

Intermediate Half Marathon Training Plan Workouts

The intermediate half marathon training plan has three days per week of running, one strength workout, and maxes out at roughly five and a half hours of training per week.

Intermediate runners are experienced runners who are one of the following:

Athletes who have more time to train than just the bear minimum
New runners who have a very athletic background or runners at least six months of running experience
Dedicated runners looking to finish finish races really well, but are comfortable not trying to squeeze every last second of time out of their race performance

Long Run (50mins - 2:15hrs): the most important run in a run training plan is the weekly long run that most runners do on the weekend when they have more time available. The long run is low intensity, building up gradually to eventually reach 2:15 hours for a half marathon training program. This run will build endurance and teach your body to produce the energy necessary to complete the distance of your race. You can learn all about the long run, how to execute it well, and what to eat before and during the long run in this article.

Here is an example of what a simple long run looks like from a half marathon training plan in our app.

Interval Run (40-80mins): The second most important run in a run training plan is a weekly interval run, which we call the “Intense Run” in our training plans. Most athletes do this run during the weekday. The interval run will build your top end speed and be based on your run pace determined in the calculator above. You can learn all about how to execute an interval run, and what to eat before and during the workout to get the most out of it in this article here.

Here is an example of what an interval run looks like from our half marathon training plan.

‍

Tempo Run (45mins - 2hrs): The weekly tempo run (which we call the steady run) bridges the gap between the endurance you’ll build in the long run, and the speed you build in the interval run, it teaches you how to run fast without getting tired. Tempo runs have been proven to be a key component of a successful run training plan. You can learn all about tempo runs in this article here.

Here is an example of what a tempo run looks like from our half marathon training plan.

‍

Strength Workout (30 minutes): Cross-training with strength workouts is critical for athletes who don’t want to simply finish their race and want to finish feeling strong. Strength training for runners has been proven to improve race performances, and athletes tend to feel much better physically. We believe so strongly in strength training that our app has 25 hours of guided strength workouts designed specifically for the needs and imbalances of endurance athletes. You can read all about strength training for runners here.

Here is an example of what a strength workout looks like from a half marathon training plan in our app.
