This is a great session that targets multiple energy systems with reps of a three-minute duration followed by a higher intensity. All runners (and triathletes) can benefit from this higher intensity of training, especially athletes with events between 5 and 10km in distance.
Each week I will be posting the Friday Fartlek Run Sessions that you can do to enhance your running. Fartlek is a Swedish term that is often used by runners and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.
The inspiration for today’s workout comes from the Kiwi Running Show podcast from last year, where Hayden Shearman and Stefan Smith discussed this workout. Listen to the podcast here.

Kiwi Running Show’s Split Session
- 10min WU Level II;
- 6x
- 3:00min Level IV,
- 30sec Level V,
- 90sec RI;
- 10min CD Level II;
- 10min Stretching
Start the workout with a Warm Up (WU) of ten minutes of easy jogging at Level II.
The Main Set is made of six reps, each rep is three and a half minutes long. Start the rep with three minutes running at Level IV, then increase the intensity to Level V for the next 30 seconds. After each rep take a 90-second Rest Interval (RI).
The Cool Down (CD) is at a low intensity, jogging (Level II) for a minimum of ten minutes.
Finish with 10 minutes of stretching to assist with the recovery.
