Classic Fartlek Workout:

The classic Fartlek workout is an excellent introduction to this type of training. It involves a continuous run during which you’ll intersperse random bursts of speed, followed by recovery periods at an easy pace. You can use landmarks, like trees or lampposts, as cues for your speed bursts and recovery intervals.

  • Warm-up: 5-10 minutes of easy jogging, followed by dynamic stretches
  • Main workout: 20-30 minutes of continuous running, with random speed bursts and recovery intervals
  • Cool-down: 5-10 minutes of easy jogging, followed by static stretches

Hill Fartlek Workout:

Hill Fartleks add an extra challenge to your workouts by incorporating uphill and downhill bursts. This variation helps improve strength, power, and running economy.

  • Warm-up: 5-10 minutes of easy jogging, followed by dynamic stretches
  • Main workout: 20-30 minutes of continuous running on a hilly route, with uphill and downhill speed bursts and recovery intervals
  • Cool-down: 5-10 minutes of easy jogging, followed by static stretches

Time-Based Fartlek Workout:

In a time-based Fartlek workout, you’ll use a timer or stopwatch to dictate your speed bursts and recovery intervals. This approach adds an element of structure to your Fartlek session, making it more similar to traditional interval training.

  • Warm-up: 5-10 minutes of easy jogging, followed by dynamic stretches
  • Main workout: 20-30 minutes of continuous running, with timed speed bursts and recovery intervals (e.g., 1-minute speed burst, followed by 2-minute recovery)
  • Cool-down: 5-10 minutes of easy jogging, followed by static stretches

Partner Fartlek Workout:

A partner Fartlek workout involves running with a friend or training partner, taking turns leading and following. The leader sets the pace and determines the speed bursts, while the follower tries to keep up. This adds an element of unpredictability and competition to the workout, making it even more engaging.

  • Warm-up: 5-10 minutes of easy jogging, followed by dynamic stretches
  • Main workout: 20-30 minutes of continuous running with a partner, alternating between leading and following for speed bursts and recovery intervals
  • Cool-down: 5-10 minutes of easy jogging, followed by static stretches

Sport-Specific Fartlek Workouts:

Runners who participate in other sports can tailor Fartlek workouts to the specific demands of their sport. For example, soccer players or basketball players can use Fartlek training to simulate the varying intensity and movement patterns they’ll experience during a game.

  • Warm-up: 5-10 minutes of easy jogging, followed by sport-specific dynamic stretches
  • Main workout: 20-30 minutes of continuous running or sport-specific movements, with speed bursts and recovery intervals that mimic the demands of your sport
  • Cool-down: 5-10 minutes of easy jogging or sport-specific movements, followed by static stretches

Progressing with Fartlek Training:

As you become more experienced with Fartlek training, you can gradually increase the intensity, duration, and frequency of your speed bursts. You can also experiment with different workout variations to keep your training fresh and challenging.

  • Increase the length of speed bursts (e.g., from 30 seconds to 2 minutes)
  • Decrease recovery intervals between speed bursts
  • Add more speed bursts to your workouts
  • Mix up the workout variations (e.g., hill Fartleks, partner Fartleks, etc.)

Tips for Successful Fartlek Sessions:

  • Listen to your body and adjust your workouts accordingly
  • Focus on maintaining proper running form during speed bursts
  • Use a variety of terrains and routes to keep your workouts engaging
  • Include Fartlek sessions once or twice a week in your training plan
  • Be creative and have fun with your workouts

Frequently Asked Questions

Does fartlek training improve stamina?

Yes, fartlek training can improve stamina by challenging the cardiovascular system and building endurance. By alternating between high-intensity running and recovery periods, you’re training your body to adapt to different workloads and intensities. This helps develop the aerobic system, which is crucial for maintaining stamina during long-duration activities.

How can fartlek training improve speed?

Fartlek training improves speed by incorporating short, high-intensity bursts of running into your workout. These bursts help develop your fast-twitch muscle fibers and improve your anaerobic capacity, both of which contribute to increased speed. As you practice accelerating during these bursts, you also improve your running mechanics, making it easier to switch gears and run faster when needed.

What are 2 examples of fartlek training?

Example 1: Speed Play in a Park

  • Warm-up with a 10-minute easy jog
  • Choose landmarks in the park (trees, benches, etc.) and sprint to each landmark, followed by a recovery jog to the next one
  • Continue alternating between sprints and recovery jogs for 20-30 minutes
  • Finish with a 10-minute cool-down jog

Example 2: Time-Based Fartlek

  • Warm-up with a 10-minute easy jog
  • Alternate between 1 minute of fast running and 1 minute of recovery jogging
  • Repeat this pattern for 20-30 minutes
  • Finish with a 10-minute cool-down jog

What is fartlek training for speed?

Fartlek training for speed focuses on incorporating short, high-intensity bursts of running that target the development of fast-twitch muscle fibers and anaerobic capacity. By incorporating these bursts into your workout, you challenge your body to adapt to faster running speeds, ultimately improving your overall speed and acceleration.

What is a fartlek run and how can it help you get faster?

A fartlek run is a type of interval training that combines faster running periods with slower recovery. The term “fartlek” is Swedish for “speed play,” emphasizing this training method’s unstructured and playful nature. Fartlek runs can help you get faster by improving your aerobic and anaerobic capacity, developing fast-twitch muscle fibers, and enhancing your running mechanics. This type of training also helps build mental toughness, allowing you to push through discomfort and maintain a faster pace when necessary.

What is a good fartlek workout?

A good fartlek workout can be tailored to an individual’s fitness level and goals. Here’s an example of a versatile fartlek workout:

  • Warm-up: 10-minute easy jog
  • Main workout: Alternate between 2 minutes of fast running and 2 minutes of recovery jogging. Repeat this pattern 8 times (for a total of 32 minutes)
  • Cool-down: 10-minute easy jog

You can modify the duration and intensity of the fast intervals and recovery periods based on your fitness level and goals. The key is to challenge yourself during the fast intervals while allowing adequate recovery during the slower periods.


Fartlek training offers a dynamic and enjoyable approach to running workouts, with a wealth of benefits for runners of all levels. 

By incorporating Fartlek sessions into your training routine, you’ll not only improve your speed and endurance but also keep your workouts fresh and engaging. 

So, why not give Fartlek training a try and experience the fun and versatility of “speed play” firsthand? Happy running!
