Whether you’re a beginner or an experienced runner, incorporating fartlek training into your routine can help you boost your speed, endurance, and overall fitness. In this guide, we’ll look at everything you need to know about fartlek training, including its definition, benefits, different variations, and sample workouts. So, lace up your running shoes and let’s dive in.
What is Fartlek Training?
Fartlek, a Swedish term meaning “speed play,” is a form of interval training that combines continuous running with varying speeds and intensities. It was developed by Swedish Olympic athlete Gosta Holmer to introduce variety and improve fitness. Unlike structured interval training or tempo running, fartlek training offers a more flexible and unstructured approach. It allows you to adjust your pace and distance based on how you feel during the run. This individualised and adaptable nature of fartlek training makes it a fun and engaging workout for runners of all levels.
Benefits of Fartlek Training
Incorporating fartlek training into your running routine offers a range of benefits that can enhance your overall performance. Here are some key advantages of fartlek training:
Improved Endurance and Speed

Fartlek training helps improve your cardiovascular fitness, endurance, and speed. By incorporating bursts of faster running into your workout, you challenge your body to adapt to different paces and intensities. This variation in speed and effort forces your heart and lungs to work harder, ultimately increasing your aerobic capacity. Over time, this can lead to improved endurance and the ability to sustain faster speeds during races and long-distance runs.
Enhanced Mental Toughness and Focus
Fartlek training not only strengthens your physical abilities but also builds mental toughness and focus. As you push yourself outside your comfort zone and tackle varying speeds, you develop resilience, willpower, and the ability to overcome mental barriers during races. The mental challenge of fartlek training prepares you to stay strong and determined, even when faced with fatigue or the desire to give up. This mental fortitude can be a game-changer in competitive running.
Versatility and Variety
One of the major advantages of fartlek training is its versatility and adaptability. You can perform fartlek runs on any surface, such as roads, trails, tracks, or even on a treadmill. Additionally, you have the freedom to choose your own landmarks or time intervals to dictate the pace changes. This flexibility allows you to explore different routes, scenery, and terrains, making your runs more enjoyable and engaging. The variety in fartlek training keeps your workouts fresh and prevents boredom, ultimately motivating you to stick to your training plan.
Improved Running Economy and Form
Fartlek training helps improve your running economy, which refers to the efficiency of your running technique and energy utilisation. By incorporating faster intervals into your runs, you activate different muscle fibres and engage your cardiovascular system more intensively. This increased demand on your body forces it to adapt and become more efficient in delivering oxygen to your muscles. As a result, your overall running form, efficiency, and performance can improve.
Time Efficiency
Fartlek training can be a time-efficient workout option for busy runners. Unlike structured interval training, which often involves specific rest and work intervals, fartlek runs allow you to seamlessly transition between different paces without the need for strict timing. This eliminates the need for constantly checking your watch or adhering to a rigid schedule. With fartlek training, you can make the most of your workout time by incorporating intervals based on how you feel and the natural flow of your run.
Advantages and Disadvantages of Fartlek Training
Like any training method, fartlek training has its own set of advantages and disadvantages. Understanding these can help you determine if fartlek training is the right fit for your running goals and preferences. Let’s explore the pros and cons of fartlek training:
Advantages of Fartlek Training
- Flexibility and Adaptability: Fartlek training allows you to adjust your pace and distance based on how you feel, making it suitable for runners of all levels. You have the freedom to tailor your workouts to your individual needs and preferences.
- Increased Motivation: The variety and unpredictability of fartlek training can keep you motivated and engaged in your running routine. The ability to explore different paces and terrains adds an element of excitement and challenge to your workouts.
- Improved Mental Resilience: Fartlek training challenges you to push through discomfort and fatigue, helping you develop mental toughness and resilience. Over time, this mental strength can extend beyond your running and positively impact other areas of your life.
- Efficient Use of Time: Fartlek training eliminates the need for strict timing and allows for seamless transitions between paces. This makes it a time-efficient workout option, especially for those with busy schedules.
Disadvantages of Fartlek Training
- Lack of Structure: Fartlek training’s unstructured nature can be a disadvantage for those who prefer a more regimented training plan. If you thrive on specific guidelines and measurable targets, other training methods like interval training or tempo runs may be more suitable.
- Risk of Overexertion or Injury: Fartlek training’s flexibility can also pose a risk if not approached with caution. Without a structured plan, it’s easy to push yourself too hard or neglect proper rest and recovery, potentially leading to overexertion or injury.
- Limited Focus on Specific Training Goals: Fartlek training’s emphasis on variety and adaptability may not be ideal if you have specific training goals, such as improving your race pace or targeting a specific distance. Other training methods may provide more targeted and measurable results in these cases.
- Requires Self-Discipline: With the freedom to adjust your pace and intensity, fartlek training requires self-discipline to maintain a balance between challenging yourself and avoiding overexertion. It’s important to listen to your body and make mindful decisions during your runs.
How is Fartlek Training Different from Other Speed Training Methods?

While fartlek training shares similarities with other speed training methods like interval training and tempo runs, it has its own unique characteristics that set it apart. Here’s how fartlek training differs from other speed training methods:
Interval Training
Interval training involves alternating between periods of high-intensity effort and recovery. It follows a structured format with specific work and rest intervals. In contrast, fartlek training offers more flexibility and freedom in adjusting your pace and distance. Fartlek runs allow you to seamlessly transition between faster and slower speeds without strict timing.
Tempo Runs
Tempo runs focus on running at a steady, challenging pace that is slightly below your maximum effort. These runs typically involve a warm-up, a sustained effort at your tempo pace, and a cool-down. Fartlek training, on the other hand, incorporates intervals of faster running with periods of easy running. It allows for more variation and unpredictability in pacing.
While all these speed training methods have their merits, fartlek training stands out for its versatility, adaptability, and enjoyment factor.
Fartlek Workouts

Fartlek workouts can be customised to fit your fitness level, training goals, and preferences. Here are three sample fartlek workouts to get you started:

- Once you reach the peak (e.g., 5 minutes), start decreasing the duration of the faster intervals by 1 minute with each repetition.
- Finish with a 10-minute cool-down jog.
Remember to listen to your body, adjust the intensity and distance based on your fitness level, and gradually progress as you become more comfortable with the workouts.
Tips for Fartlek Training
To make the most out of your fartlek training and ensure a safe and effective workout, consider these tips:
Start Gradually: If you’re new to fartlek training, start with shorter intervals and slower paces. Gradually increase the duration and intensity of your intervals as you become more comfortable and fit.
Listen to Your Body: Pay attention to how your body feels during the run. If you’re feeling fatigued or experiencing pain, slow down or take a break. Fartlek training should challenge you, but it shouldn’t lead to overexertion or injury.
Proper Warm-up and Cool-down: Begin each fartlek session with a 10-minute warm-up jog to prepare your muscles and gradually increase your heart rate. After the main workout, finish with a 10-minute cool-down jog to help your body recover and prevent muscle soreness.
Mix Intensity and Distance: Experiment with different combinations of intensity and distance in your fartlek runs. You can have shorter, high-intensity intervals followed by longer recovery periods or vice versa. Play around with the intervals to keep your workouts diverse and challenging.
Stay Hydrated: Hydration is crucial during any workout. Make sure to drink enough water before, during, and after your fartlek runs to maintain optimal performance and prevent dehydration.
Have Fun: Fartlek training is all about enjoying the process and embracing the variety. Celebrate your accomplishments, challenge yourself, and find joy in the journey. Remember, every run is an opportunity to improve and grow as a runner.
