What is Fartlek Training?

Fartlek training is a versatile and dynamic form of interval training that combines periods of fast-paced running with recovery jogs or walks. Unlike traditional interval training, which is structured and includes prescribed times and distances, Fartlek training is more flexible, allowing the individual to dictate their own pace and intensity. This makes it an ideal workout for runners looking to improve their speed, endurance, and mental toughness.

Why Treadmill Fartlek Training?

While Fartlek training is typically performed outdoors, incorporating it into your treadmill workouts can offer several advantages:

A. Controlled Environment: Treadmill training provides a stable, controlled environment, making it easier to focus on your workout without worrying about external factors like weather, traffic, or uneven terrain.

B. Consistency: Running on a treadmill allows you to maintain a consistent pace, which is crucial for effectively training your cardiovascular system and improving your running form.

C. Safety: Treadmill workouts eliminate the risk of injury from tripping or falling on uneven surfaces, making it a safer option for those new to interval training or those with a history of injuries.

Designing a Treadmill Fartlek Workout

A successful treadmill Fartlek workout consists of four key components:

A. Warm-up: Begin with a 5-10 minute warm-up jog at a comfortable pace. This will increase your heart rate and prepare your muscles for the high-intensity intervals to come.

B. Intervals: The heart of the workout, these intervals can range from short bursts of speed lasting 30 seconds to longer, sustained efforts of 5 minutes or more. The intensity should be challenging but manageable. Adjust the treadmill speed and incline to simulate hill sprints or sustained climbs.

C. Recovery: Following each interval, allow your body to recover with a jog or walk. The duration of recovery should be roughly equal to the length of the high-intensity interval.

D. Cool-down: Finish your workout with a 5-10 minute cool-down jog or walk to help your heart rate return to normal and prevent muscle stiffness.

Sample Treadmill Fartlek Workouts

Here are three sample treadmill Fartlek workouts for different fitness levels:

A. Beginner: Start with a 5-minute warm-up jog, then alternate 1-minute intervals of running at a challenging pace with 1-minute recovery jogs. Repeat this cycle 5-10 times, followed by a 5-minute cool-down.

B. Intermediate: After a 10-minute warm-up jog, alternate 2-minute intervals of running at a challenging pace with 1-minute recovery jogs. Repeat this cycle 6-10 times, followed by a 5-minute cool-down.

C. Advanced: Warm up for 10 minutes, then complete a series of intervals with varying lengths and intensity, such as 5 minutes at a challenging pace, 2 minutes at an even faster pace, and 1-minute all-out sprints. Include recovery jogs between each interval. Complete the workout with a 5-10 minute cool-down.

Tips for Success

A. Listen to Your Body: Fartlek training is designed to be flexible, so adjust your workout based on your feelings. If

you’re feeling strong and energetic, push yourself to increase the intensity or duration of your intervals. Conversely, if you’re feeling fatigued, take it easy and focus on recovery.

B. Progress Gradually: As with any exercise program, gradually increasing intensity and duration is essential to prevent injury and burnout. Start with shorter intervals and build up over time.

C. Mix It Up: One of the benefits of Fartlek training is its versatility. Keep your workouts interesting by varying the length, intensity, and incline of your intervals. This will prevent boredom and challenge your body in new ways, leading to better overall fitness gains.

D. Focus on Form: Running on a treadmill provides an excellent opportunity to focus on proper running form. Keep your upper body relaxed, engage your core, and maintain a smooth stride. Good form will help prevent injuries and improve your running efficiency.

E. Use Technology: Many modern treadmills come with pre-programmed interval workouts or allow you to create custom programs. Take advantage of these features to make your Fartlek training more convenient and engaging.

F. Don’t Neglect Recovery: Adequate recovery prevents injury and promotes progress. Ensure you allow enough time for your body to recover between high-intensity intervals and incorporate rest days into your overall training plan.


Treadmill Fartlek training offers a flexible, engaging, and effective way to improve your cardiovascular fitness, speed, and endurance.

By incorporating this dynamic form of interval training into your treadmill workouts, you’ll reap the physical benefits and keep your exercise routine fresh and exciting. Remember to listen to your body, progress gradually, and focus on proper running form to maximize your results and minimize the risk of injury.
