Garmin VO2 Max B
Running, August 19, 2025
VO2 Max sessions are a great way to build your top end speed, with a short rest like this workout has you will also develop your short term tolerance to higher lactic acid levels. This session is great for athletes running 5km & 10km events, as well as sprint and Olympic distance triathletes.
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 came up on my Garmin watch as part of my Obey the Watch series.

Garmin VO2 Max B
- 10min WU Level II;
- 7x 2min Level V, 1min Level I RI;
- 10min CD Level II;
- 10min Stretching
The Warm Up (WU) should be done at an intensity that is steady but not over consuming at Level II for ten minutes.
The main set is made up of seven, two-minute reps run at Level V. Take a minute Rest Interval (RI) between reps.
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 doing the workout:
