Can Fartlek workout improve your running speed?

Yes, the Fartlek workout will improve your running speed. Fartlek is a Sweedish term that means “speed play”. This training greatly improves your speed and endurance. Fartlek training incorporates running at a higher pace and then reducing the speed. Running at a higher pace improves your average running speed.

Let’s learn more about it.

What is Fartlek Workout?

The Fartlek running workout is basically interval training that involves speed variations throughout your run.

Typically you start with an easy warm-up.

Once you are ready, you increase your speed considerably high.

Then again you decrease the speed to a moderate or comfortable pace for recovery.

This tunes your muscles to adapt to the speed variations quickly and helps you immensely in improving your average speed.

If you shorten your recovery period, this will help in building up your stamina.

Is Fartlek Training the Same As Interval Training?

A general interval training can be any training with a mix of high and low-intensity workouts.

Whereas, the Fartlek training is restricted just to running.

Also, in most cases, interval training is structured and has a specific time or measured segments.

However, ideal Fartlek training is mostly unstructured.

You can run a fast segment or slow down to catch a breath as per your requirement.

If you are running on the street, you can select a lamp post or a car parked at a distance as a reference to speed up.

This makes your running fun and breaks the monotonous.
