This session is a great way to increase your Threshold running pace. This is a great workout for someone training for 5km or 10km.
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.

4x 5min Threshold Runs
- 10min WU Level II;
- 4x 5min Level IV, 1min RI Level II;
- 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 four reps running at Level IV for five minutes. After each rep jog for 60 seconds as a Rest Interval (RI).
The Cool Down (CD) is at low-intensity jogging (Level II) for a minimum of ten minutes.
Finish with 10 minutes of stretching to assist with the recovery.
Here is my data from running this session:
