What is the Beep Test?

The beep test is one of the most widely used aerobic fitness assessments in the world. Also known as the multi-stage fitness test, shuttle run test, pacer test, or Léger test, it measures your maximal aerobic capacity (VO2max) through a progressive running test that gets harder each level.

How the Beep Test Works

The test is simple in concept but demanding in execution. Two markers are placed 20 metres apart on a flat surface. An audio recording plays a series of beeps, and participants must run from one marker to the other before each beep sounds.

  1. Mark out a 20-metre distance on a flat, non-slip surface.
  2. All runners line up at one end. The test begins with the first beep.
  3. Run to the other marker and arrive before the next beep sounds.
  4. Turn and run back when the beep sounds. Continue running back and forth.
  5. Each level lasts about one minute. The time between beeps decreases each level, requiring progressively faster running.
  6. A triple beep signals the start of a new level and a speed increase.
  7. If you fail to reach the line before the beep twice in a row, your test is over. Your score is the last level and shuttle completed.

A Brief History

The beep test was developed by Canadian researcher Luc Léger at the University of Montreal in 1982. The original protocol, published in the Canadian Journal of Applied Sport Sciences, established the 20-metre shuttle run format with progressively increasing speeds. It was designed as a practical, large-scale alternative to laboratory VO2max testing on a treadmill.

Since then, the test has been adopted worldwide by sporting organisations, military forces, police academies, fire services, and school physical education programmes.

Who Uses the Beep Test?

Sports Teams

Pre-season fitness testing, squad selection, and monitoring training adaptations. Used in football, rugby, basketball, hockey, netball, and more.

Military & Police

Recruitment fitness standards and annual assessments. Many forces worldwide set minimum beep test levels for entry.

Schools

The FITNESSGRAM PACER test is the standard aerobic capacity assessment in US schools. Used in physical education across K-12.

Personal Fitness

Self-assessment and goal-setting. Track your beep test level over time to measure cardiovascular fitness improvements.

Beep Test Protocols

There are two main protocols in common use. Both use a 20-metre distance with 21 levels, but differ in starting speed:

  • Léger 20m — Starts at 8.5 km/h. Used internationally by sports and military organisations. Compare protocols →
  • FITNESSGRAM PACER — Starts at 8.0 km/h. The standard in US schools.

What Does the Beep Test Measure?

The primary measurement is VO2max — the maximum rate of oxygen your body can use during intense exercise, expressed in ml/kg/min. Higher VO2max indicates better cardiovascular fitness. The beep test estimates VO2max based on the final speed (level) achieved. Calculate your VO2max →
