What is Fartlek Training?

“Fartlek training” is a fancy term for a workout routine where you mix up the intensity and speed of your exercise, kind of like interval training. Interval training is a form of exercise that can be beneficial for enhancing your fitness and well-being. It differs from traditional speed workouts in that it is more unstructured and can be easily adapted to different fitness levels.


Fartlek training mingles continuous running with bursts of speed, challenging the runner’s endurance and ability to recover. The Swedish term “fartlek” translates as “speed play,” aptly summarizing this blend of steady jogs with spontaneous sprints or hill climbs. Runners shift gears at irregular intervals, injecting variety and unpredictability into their workout. This type of training contrasts sharply with structured interval training, which typically involves predetermined distances or times.

Incorporating random speed work into a cardio session turns a standard run into a dynamic fartlek workout. A runner may sprint to the next lamppost, then jog until they see a red car, followed by maintaining a brisk pace for several minutes before slowing down again.

These abrupt changes in pace can simulate the unpredictable conditions of race day. They also push runners to improve flexibility in their strategy while boosting both aerobic and anaerobic fitness levels without strict limitations on rest periods or intensity.

Differentiating from other speed workouts

Fartlek training differs from other speed workouts like interval and tempo runs in its unstructured nature. Unlike a set distance or time for each speed segment, Fartlek involves random variations in pace.

This allows for continuous running with intervals of varying intensity effortlessly integrated into the workout, making it more adaptable than traditional speed workouts.

Unlike interval training, which usually involves high-intensity bursts followed by recovery periods, fartlek sessions include alternating between bursts of sprinting and slower running at various points during the run.

While tempo runs focus on maintaining a challenging but sustainable pace over a more extended period to increase the lactate threshold, Fartlek challenges the body to adapt to multiple speeds and intensities throughout the workout without fixed segments or paces.

Benefits of Fartlek Training

Fartlek training offers improved mind-body awareness, mental strength, and stamina improvement. Incorporating fartlek workouts into your routine can help enhance overall running performance and endurance.

Improved mind-body awareness

Improved mind-body awareness is a crucial benefit of fartlek training. This workout encourages runners to tune into their bodies, making them more attuned to their breathing, heart rate, and muscle fatigue.

By incorporating random bursts of speed and intensity, athletes learn to listen to their bodies and adjust their pace accordingly, enhancing their overall mindfulness during the run.

Fartlek training also enables individuals to develop a deeper connection between physical sensations and mental focus while running, promoting a heightened sense of mind-body coordination.

By doing fartlek workouts, you can improve your mind-body coordination and become more aware of your physical abilities. This can help you perform better in various areas of your life, such as sports, work, and everyday activities. As runners become more in tune with how different speeds feel within their body’s natural rhythm, they can transfer this self-awareness beyond running sessions.

Mental strength

Fartlek training is a great way to build mental strength, as it challenges runners to push through varying speeds and intensity levels. This type of workout helps improve the ability to maintain focus and determination during runs, which can be beneficial for races or long-distance training.

The random variations in speed require runners to stay mentally engaged, ultimately building resilience and mental toughness.

The unpredictable nature of fartlek training also enhances a runner’s ability to adapt to changing conditions on race day. By practicing running at different paces and intensities, runners can develop the mental flexibility to adjust their strategy during competitions.

This type of mental resilience can help athletes overcome obstacles and push through fatigue when it matters most. Incorporating fartlek workouts into a training routine can contribute significantly to strengthening both the body and mind for improved overall performance.

Stamina improvement

Improving stamina is a crucial benefit of fartlek training. Challenging the body with varying speeds and intensities enhances endurance for race paces. This unique blend of continuous running and intervals conditions the body to adapt to various speeds, ultimately improving overall running performance.

Fartlek training also helps runners develop mental strength, crucial in enduring long distances and maintaining consistent speed throughout a race. The unstructured nature of fartlek workouts challenges runners to push through fatigue and discomfort, leading to improved mind-body awareness and the ability to sustain effort over extended periods.

How to Incorporate Fartlek Training Into Your Workouts

“Here are some examples of fartlek sessions and tips for beginners looking to incorporate fartlek training into their workouts.”

Examples of fartlek sessions

Fartlek sessions can be customized to fit your fitness level and running goals. Here are some examples:

  1. Mix it up: Start with a 10-minute warm-up at a leisurely pace, then alternate between 1 minute of hard effort and 2 minutes of easy jogging for 20 minutes. Finish with a 10-minute cooldown.
  2. Hill surges: Find a hilly route and insert short, intense bursts of speed when going uphill, followed by recovery jogs downhill or on flat terrain.
  3. Speed play: During a regular run, pick random landmarks like trees or lamp posts and increase your speed until you reach each one, then return to your usual pace.
