PACER test with VO2 max estimate
In pairs, students complete the 20-meter PACER test with a progressive audio cadence while their partner records the laps completed. Afterward, they estimate their VO2 max and compare it with their last score to evaluate their aerobic fitness.
How to play
- Set two cone lines 20 m apart with 5-ft lanes; in pairs, one runs and one records (2 min).
- Explain the test: runners must reach the line before the beep; after two late arrivals in a row the test ends and the last full stage is recorded (3 min).
- First round: half the class runs while partners stand outside the lanes counting laps and calling out the first missed beep (8 min).
- Runners walk for 2 minutes and take their pulse; then partners switch roles and the second group runs (8 min).
- Each pair plugs the final stage speed and age into the VO2 max estimate formula the teacher posts on the board or worksheet (3 min).
- Quick wrap-up: each student compares the result with the previous test and writes one realistic goal for next term (1 min).
Rules
- Touch the line with one foot at every turn; turning early does not count.
- Each runner stays in their own lane to avoid collisions at the turns.
- Anyone who feels dizzy or has chest pain stops and tells the teacher right away.
- Recorders score honestly and do not yell at or pressure the runner.
Variations
Easier
Run a 15-meter version with a conversion chart for students who are just starting endurance training.
Standard
Full 20-meter test until two missed beeps in a row, with the VO2 max estimate calculated in pairs.
Harder
In addition to the score, pairs record heart rate at the finish and one minute later to evaluate recovery.
Adaptations
- Limited mobility: complete the test in a wheelchair on a 10-meter course, or serve as the official audio timer.
- Hearing impairment: the recorder raises an arm on every beep and a tablet adds a visual flash cue.
- Low fitness level: the student may stop at the first missed beep and aims to beat their own stage, not the class.
Learning goals
- Measure aerobic capacity with a valid, standardized test.
- Calculate and interpret an estimated VO2 max from the test score.
- Set a personal improvement goal based on their own data.
Equipment for a class of 25

Teacher tip
Check the audio volume before you start and avoid testing right after lunch or in high heat. Stress that scores are personal: skip public leaderboards.
