Fartlek Session

Friday Fartlek Run: Special K’s – Cruise Ks

Doing 1km reps is very popular with Ironman triathletes and marathon runners to improve speed over the marathon distance. This is a perfect session for runners and triathletes running events up to the marathon distance or longer.

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 runners often use and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.

Over the next few weeks, I’m going to cover a number of variations of 1km repeats. The inspiration for these workouts comes from an article by Mario Fraioli. That article can be found here.

Special K’s – Cruise Ks

  • 10min WU Level II;
  • 10x 1km Level III-IV, 1min Level II RI;
  • 10min CD Level II;
  • 10min Stretching

The Warm Up (WU) should be done at an intensity that is steady, but not overconsuming at Level II for ten minutes.

The main set is made up of ten, one-kilometre reps. These reps are done at your half marathon pace, which will be the top end of Level III or the bottom end of Level IV. After each rep take a one-minute Rest Interval (RI) jogging at Level II.

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.
