  • Fats: Include healthy fats like nuts, seeds, and avocados to support proper hormone function and overall health. Aim for 20%-25% of your daily calories from healthy fats.


Keeping your body properly hydrated is a vital component of half marathon training, especially during long runs and speed workouts. Follow these hydration tips:

  • Daily hydration: Aim to consume at least half your body weight in ounces of water daily.
  • Pre-run: Drink 16-20 ounces of water 1-2 hours before a run, and another 8-10 ounces 30 minutes before running.
  • During runs: For runs longer than 60 minutes, carry a water bottle or plan for a water stop along your route, and try to drink 7-10 ounces every 10-20 minutes.
  • Post-run: Replenish lost fluids by drinking an additional 16-24 ounces of water within 30 minutes of completing your run.

Developing Endurance and Speed

Long Runs

Long runs are a crucial part of building endurance, as they help increase your weekly mileage and improve aerobic capacity.

Aim for one long run per week, extending the distance by 1-2 miles every week or two. Gradually increase your long run length to a peak of 10-12 miles at a comfortable and steady pace. This will help your body adapt to running for an extended duration.

Tempo Runs

Tempo runs, also known as threshold runs, involve running at a challenging but sustainable pace, usually around 10-20 seconds faster per mile than your target half marathon pace.

They help improve your anaerobic threshold and cardiovascular fitness. Incorporate one tempo run per week, starting with 20-minute intervals and building towards 40-50 minutes.

Interval Training

Interval training is essential for developing speed and strength. It consists of alternating high-intensity efforts with recovery periods. Begin with short intervals, such as 400-meter repeats at your desired 5K pace, with equal recovery time in between.

Gradually progress to longer intervals, such as 800 meters or 1,600 meters. Include interval training in your weekly routine, but limit it to one session per week to avoid overtraining.

Hill Training

Hill training can be particularly beneficial for increasing leg strength and improving running form.

Dedicate one day a week to hill training, focusing on maintaining good form, engaging your glutes, and leaning slightly forward while climbing the hill. Increase the hill’s length and incline gradually over time, ensuring proper recovery between hill repeats.

Fartlek Training

Fartlek, a Swedish word for “speed play,” is a versatile and adaptable training method that combines elements of endurance and speed training. During a Fartlek run, alternate between fast, moderate, and easy-paced running, varying the duration and intensity at your discretion.

This type of training helps you develop a stronger aerobic base while improving your speed in a less structured way. Include Fartlek training once every 1-2 weeks.

Incorporate each of these training types into your half marathon preparation to develop both endurance and speed. Stay consistent in your training, gradually increasing mileage and intensity throughout the weeks leading up to your goal race.

Remember to prioritize recovery and listen to your body’s needs to maximize your progress and stay injury-free.

Strength and Cross-Training

Core Exercises

Incorporating core exercises into your training plan is crucial for building strength to maintain an efficient running form.

A strong core helps with overall stability, balance, and injury prevention. Here are a couple of core exercises you can include in your routine:

  • Planks: Hold a plank position for 30-60 seconds or more, aiming for 3 sets.
  • Russian twists: Perform 3 sets of 12-15 reps, with or without weight.
  • Bridges: Perform 3 sets of 15 reps, holding each rep for 3-5 seconds.


Cycling is a low-impact cross-training activity that helps build cardiovascular fitness without the impact stress of running.

It can aid in muscle strength and endurance, particularly for the quadriceps, hamstrings, and glutes. Including one or two cycling sessions per week can complement your running workouts and help stave off injury. Aim for 30-60 minutes per session, maintaining a steady yet challenging pace or incorporating intervals for variety.


Swimming is another low-impact cross-training option that works your entire body, promoting cardiovascular fitness and muscular endurance.

It also helps improve lung capacity and breath control, which can be beneficial for runners. Incorporate one or two 30-45-minute swim sessions per week, focusing on different strokes to work various muscle groups.


Yoga is a valuable addition to a runner’s training due to its focus on flexibility, strength, and balance. It can help improve posture, prevent injuries, and enhance mental focus. Including a yoga session one or two times per week can complement your running workouts and support overall well-being.

Consider attending a class or following an online routine tailored for runners, focusing on stretching the hamstrings, hip flexors, and calves while emphasizing core strength.

Planning Your Training Cycle

Weekly Mileage

To achieve a sub-2 hour half marathon, aim for a weekly mileage of 15-30 miles. This amount is essential to building the fitness and endurance needed for the race.

It’s vital to start slow and gradually increase your mileage week by week. A typical weekly schedule might look like this:

  • Monday: Easy run
  • Tuesday: Speed workout
  • Wednesday: Rest or Cross-training
  • Thursday: Variable (easy or pace-based runs)
  • Friday: Rest
  • Saturday: Long run
  • Sunday: Recovery run

Progression and Periodization

Periodization is crucial in preparing for a sub-2 hour half marathon. This approach involves dividing your training into distinct phases with specific goals for each stage.

Ideally, start with a base phase to build up your running fitness; followed by a build phase, which increases intensity and mileage; then a peak phase, during which you work on speed and race-specific workouts.

  • Consuming a recovery meal or snack within 30-60 minutes after a workout to replenish lost nutrients
  • Ensuring adequate sleep, aiming for 7-9 hours each night
  • Balancing intensity in your training with slower, easy-paced runs or rest days

Race Day and Pacing Strategies

Race Pace Preparation

To run a half marathon in under 2 hours, aim for an average pace of 9:09 minutes per mile or 5:41 minutes per kilometer. To achieve this target race pace, it’s important to train consistently, focusing on mileage, tempo, and interval runs:

  • Weekly mileage: 15-30 miles
  • Recent 10K time: 54:00 or under

During your training, experiment with your target pace during easy runs and interval workouts, to become familiar with it and build confidence.

| Workout               | Distance / Intensity   |
| Intervals             | 5 x 1 mile repeats     |
| Easy Run              | 6 miles                |
| Tempo Run             | 5 or 6 miles           |
| Rest or Easy Run      | 3 or 4 miles           |

Even Pacing versus Variable Pacing

In half marathon races, it’s crucial to maintain a consistent and steady pace. That means striving to maintain an even pace throughout the race rather than alternating between fast and slow paces. Runners with more experience can experiment with variable pacing, adjusting their speed as needed during the race.

  • Even pace: Maintain the target race pace of 9:08 per mile throughout the race
  • Variable pace: Experienced runners can adjust their pace in response to race conditions

Pace Strategy on Hills

Implementing a smart hill strategy can make all the difference when running a race with elevation changes. Practice hill repeats during training to build strength and refine your pacing strategy:

  1. When approaching a hill, maintain the same effort level as on flat terrain, rather than focusing on maintaining a specific pace. This will prevent excessive energy expenditure on inclines.
  2. As you crest the hill, avoid the temptation to immediately speed up. Instead, gradually return to your target race pace during the descent, while allowing gravity to assist you.
  3. Consider your overall pace strategy on hilly courses, factoring in hill climbs and descents. This may involve some adjustments to the target race pace but enables a more strategic approach to race day pacing.
