Half Marathon Training Plan

Why Train Specifically for a Half Marathon?

The half marathon places a sustained demand on your aerobic system, while still requiring controlled intensity.

Your performance is shaped by your glycogen stores, lactate threshold, and your ability to maintain efficient movement as fatigue builds.

Training for this distance helps your body to:

• Use fuel more efficiently over time
• Delay the onset of fatigue
• Maintain consistent pacing under pressure

This is not just about endurance. It is about endurance with control.

The Approach

This plan is built around structure, progression, and awareness.

Weekly long runs that gradually increase
These develop both physical and mental endurance.

Pace specific workouts
You will learn how different efforts feel and how to control them.

Nutrition and recovery focus
Fueling and rest become critical as distance increases.

Consistency over intensity
The goal is to build sustainable fitness, not short term gains.

Weekly Structure

You will run 4 times per week:

• Run 1: Easy Run
• Run 2: Pace Specific Session
• Run 3: Recovery Run
• Run 4: Long Run

Optional cross training or rest can be added depending on experience.

Understanding Your Effort Levels

• Easy Pace: Comfortable, conversational
• Steady Pace: Controlled effort, slightly challenging
• Half Marathon Pace: Sustainable but focused effort
• Tempo Pace: Challenging, requires concentration

Learning these effort levels is essential for managing race day.

The 10 Week Plan

Weeks 1 to 2: Building the Foundation

You begin by establishing routine and aerobic strength.

• Easy Run: 30 minutes
• Steady Run: 25 minutes
• Recovery Run: 20 to 25 minutes
• Long Run: 50 to 60 minutes

Theory focus: You are developing your aerobic base and improving your ability to utilise oxygen efficiently.

Weeks 3 to 4: Extending Distance

You begin to stretch your long run and introduce pacing awareness.

• Easy Run: 35 minutes
• Pace Session: 3 x 8 minutes at steady pace with 2 minutes recovery
• Recovery Run: 25 minutes
• Long Run: 65 to 75 minutes

Theory focus: Gradual increases in volume improve endurance without overwhelming your recovery systems.

Weeks 5 to 6: Introducing Half Marathon Pace

Now you begin to train specifically for race effort.

• Easy Run: 35 to 40 minutes
• Pace Session: 2 x 12 minutes at half marathon pace
• Recovery Run: 25 to 30 minutes
• Long Run: 80 to 90 minutes

Theory focus: Training at race pace improves efficiency and helps you internalise the effort required on race day.

Weeks 7 to 8: Building Strength and Durability

This is where endurance and pacing come together.

• Easy Run: 40 minutes
• Tempo Session: 20 minutes at tempo pace
• Recovery Run: 30 minutes
• Long Run: 95 to 105 minutes

Theory focus: Sustained efforts improve your lactate threshold, helping you maintain pace for longer without fatigue.

Weeks 9 to 10: Taper and Race Preparation

You reduce volume while maintaining quality.

• Easy Run: 30 minutes
• Pace Session: 2 x 10 minutes at half marathon pace
• Recovery Run: 20 to 25 minutes
• Long Run: 60 minutes

Final Week:
Reduce volume further and include your race.

Theory focus: Tapering allows your body to recover fully while preserving fitness, ensuring peak performance.

Nutrition and Energy Management

As distance increases, fueling becomes essential.

Your body relies heavily on glycogen stores for sustained running. Poor fueling can lead to fatigue late in the run.

To support training:

• Eat consistently to support recovery
• Consider fueling strategies on longer runs
• Stay hydrated before and after sessions

Training your nutrition is as important as training your legs.

Pacing the Half Marathon

The biggest challenge is not the distance. It is pacing correctly.

A well executed half marathon should feel:

• Controlled in the early stages
• Steady and focused through the middle
• Challenging but manageable towards the end

Going out too fast is the most common mistake.

Recovery and Adaptation

Longer distances create more stress on the body.

To adapt effectively:

• Prioritise sleep
• Keep recovery runs easy
• Avoid stacking hard sessions back to back

Progress comes from balancing effort with recovery.

What You Can Expect

After 10 weeks, you should notice:

• Improved endurance and stamina
• Better pacing awareness
• Increased confidence over longer distances
• Stronger, more controlled finishes

You will not just be ready to complete a half marathon. You will be ready to run it well.

Final Thought

The half marathon rewards patience, preparation, and discipline.

It is not about simply covering the distance. It is about understanding how to manage your effort from start to finish.

Train with intention, respect the process, and you will arrive at the start line ready.
