Threshold training is one of the most effective ways to improve your parkrun performance because it teaches your body to sustain a stronger pace for longer. This parkrun Tune Up 3×5min Threshold session is designed to build speed endurance, improve pacing control, and increase your ability to handle discomfort when the pace rises. It’s a fantastic workout for parkrun runners, 5km athletes, and triathletes looking to sharpen fitness without needing a huge training volume.
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 it is to work.

3x 5min Threshold
- 10min Level II WU;
- 3x 5min Level IV, 2min Level II RI;
- 10min Level II CD;
- 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 a three reps, running at Level IV for five-minutes. Jog at Level II for two-minutes for your 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.
