The Ultimate LSD Run Guide: Long Slow Distance Running, Explained

Long Slow Distance (LSD) running is a training method that has gained popularity among both professional and amateur runners. It involves running at a comfortable, conversational pace for an extended period of time. In this article, we will explore the concept of LSD running, its benefits, how to incorporate it into your training, tips for optimizing your LSD runs, common misconceptions, and how to prepare for your first LSD run. So, lace up your running shoes and let’s dive in!

What is LSD running?

LSD running, also known as aerobic base training, is a training approach that focuses on building endurance and improving cardiovascular fitness. The goal is to run at a pace that allows you to maintain a conversation without feeling breathless. Unlike high-intensity workouts, LSD runs are performed at a slower pace, typically 60-80% of your maximum heart rate.

Benefits of LSD running

Incorporating LSD runs into your training regimen can offer several benefits:

  1. Improved endurance: LSD running helps increase your aerobic capacity, allowing you to run longer distances without fatigue.
  2. Enhanced fat burning: Running at a lower intensity encourages your body to use fat as a fuel source, making it an effective method for weight management.
  3. Reduced risk of injury: By running at a slower pace, you decrease the impact on your joints and muscles, minimizing the risk of overuse injuries.
  4. Mental toughness: LSD runs teach you to push through physical discomfort and mental challenges, helping you develop mental fortitude for long-distance running events.

How to incorporate LSD runs into your training

To incorporate LSD runs into your training routine, follow these guidelines:

  1. Gradually increase distance: Start with shorter LSD runs and gradually increase the distance over time. This approach allows your body to adapt to longer runs without risking injuries.
  2. Set a target pace: Aim to run at a comfortable pace where you can maintain a conversation. Avoid pushing yourself too hard during LSD runs.
  3. Choose appropriate terrain: Opt for flat or rolling terrains when starting LSD running. As you progress, you can add hills to challenge yourself.
  4. Include regular rest days: Rest and recovery are crucial for improving performance. Plan your LSD runs with adequate rest days in between to avoid overtraining.
  5. Incorporate cross-training: Complement your LSD runs with cross-training activities such as swimming or cycling to enhance overall fitness and prevent overuse injuries.

Tips for optimizing your LSD runs

To get the most out of your LSD runs, consider the following tips:

  1. Fuel properly: Consume a balanced meal with carbohydrates and protein before your LSD runs to provide sustained energy. During long runs, refuel with easily digestible snacks or energy gels.
  2. Stay hydrated: Drink enough fluids before, during, and after your runs to maintain optimal hydration levels.
  3. Listen to your body: If you experience pain or extreme fatigue during an LSD run, slow down or take a break. Pushing through discomfort may lead to injuries.
  4. Monitor your heart rate: Use a heart rate monitor to ensure you’re running within the target heart rate zone for LSD runs.
  5. Practice good form: Maintain proper running form by keeping your posture upright, landing mid-foot, and swinging your arms naturally. Good form reduces the risk of injuries and improves efficiency.

Common misconceptions about LSD running

Despite its benefits, LSD running is often misunderstood. Let’s debunk some common misconceptions:

  1. LSD running is only for beginners: LSD running is beneficial for runners of all levels, from beginners to experienced athletes. It helps build a strong aerobic base, which is crucial for performance improvement.
  2. LSD running hinders speed development: On the contrary, LSD running enhances endurance, which indirectly improves your speed over time.
  3. All long runs are LSD runs: Not all long runs are LSD runs. LSD runs specifically focus on maintaining a conversational pace, while other long runs may involve higher intensity intervals or tempo runs.

How to prepare for your first LSD run

If you’re planning your first LSD run, follow these steps to ensure a smooth and enjoyable experience:

  1. Select appropriate running gear: Wear comfortable, moisture-wicking clothes and supportive running shoes.
  2. Plan your route: Choose a scenic and safe route with minimal traffic and adequate water stations if needed.
  3. Warm up and stretch: Perform a dynamic warm-up routine to prepare your muscles and joints for the run. Stretching afterwards can also help with recovery.
  4. Start slowly: Begin your LSD run at a comfortable pace, gradually easing into the rhythm.
  5. Stay focused and enjoy the journey: Keep your mind engaged by listening to music, podcasts, or enjoying the scenery. Embrace the slower pace and take pleasure in the experience.

Taking your running to the next level with LSD

Once you have mastered the basics of LSD running, you can take your running to the next level by:

  1. Increasing distance: Gradually increase the distance of your LSD runs to challenge your endurance and build mental resilience.
  2. Adding intervals: Incorporate intervals of higher intensity within your LSD runs to improve speed and cardiovascular fitness.
  3. Joining a running group: Running with a group can provide motivation, accountability, and the opportunity to learn from more experienced runners.
  4. Participating in races: Test your progress and celebrate your achievements by participating in local races or even a marathon.


Q: How often should I incorporate LSD runs into my training?

A: It’s recommended to include one or two LSD runs per week in your training schedule. However, the frequency may vary depending on your training goals and overall fitness level.

Q: Can LSD running help with weight loss?

A: Yes, LSD running can aid in weight loss as it promotes fat burning and improves overall fitness. However, it’s important to combine it with a balanced diet and other forms of exercise for optimal results.

Q: How should I breathe during LSD runs?

A: Focus on deep belly breathing, inhaling through your nose and exhaling through your mouth. This breathing technique helps oxygenate your muscles and maintain a steady rhythm.

Q: Should I stretch before or after LSD runs?

A: It’s best to perform a dynamic warm-up before LSD runs to prepare your muscles. Save static stretching for after your run to help with cool-down and flexibility.

Q: Can LSD running improve my race times?

A: Yes, LSD running builds a strong aerobic base, which can improve your race times by enhancing endurance and overall running efficiency.

Q: How long should my first LSD run be?

A: Start with a distance that you feel comfortable with, such as 3-5 miles, and gradually increase it over time. Listen to your body and avoid overexertion.

Q: Is it necessary to track heart rate during LSD runs?

A: While it’s not necessary, monitoring your heart rate can help ensure that you’re running within the desired intensity zone for LSD runs. It can be a useful tool for tracking progress and preventing overexertion.

Remember, LSD running is a journey that requires patience, consistency, and a focus on your long-term goals. By incorporating LSD runs into your training routine, you can unlock your potential as a runner and enjoy the many physical and mental benefits it offers.
