This workout is suggested to increase your high aerobic load. This session is great for runner’s of all abilities, and is particularly effective for 5km and 10km runners and triathletes.
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.
This workout is part of a series of workouts that Garmin have given as recommendations for my training on my Garmin Forerunner 970 watch.

Garmin’s Recommended Threshold Run #2⅔
- 10min WU Level II;
- 17min Level IV;
- 10min CD Level II;
- 10min Stretching
Start the workout with a warm-up (WU) for ten minutes of easy jogging at Level II.
The Main Set involves completing a single seventeen-minute rep at Level IV.
The Cool Down (CD) is at a low intensity, jogging (Level II) for at least ten minutes.
Finish with 10 minutes of stretching to assist with the recovery.
Here is my data from doing the workout:
