Balke 15-minute Run

The Balke 15-minute run is a field test designed by Bruno Balke to measure aerobic fitness by determining the maximum distance covered in 15 minutes. This running test is popular among fitness enthusiasts and athletes looking to gauge their aerobic endurance. The test also provides a formula to predict VO2max based on the distance covered during the run.


The main purpose of the Balke 15-minute run is to assess an individual’s aerobic fitness, which refers to the body’s ability to utilize oxygen efficiently while running.

Equipment Required:

To conduct this test, you will need a flat oval or running track, marking cones, recording sheets, and a stopwatch. These simple and easily accessible tools make the Balke 15-minute run an affordable and convenient fitness assessment.

Pre-Test Procedures:

Before beginning the test, it is crucial to explain the procedures to the participant and ensure they understand the requirements. Additionally, conduct a screening for any health risks and obtain informed consent. Record basic information such as age, height, body weight, gender, and test conditions. Prepare the course by placing marker cones at set intervals, and make sure the participant performs an appropriate warm-up.

Test Procedure:

During the Balke 15-minute run, participants are instructed to run for 15 minutes while aiming to cover as much distance as possible. Walking is allowed, but participants are encouraged to push themselves to their limits and give their best effort.

Scoring and Predicted VO2max:

Various equations can be used to estimate VO2max based on the distance covered during the Balke 15-minute run. One such formula by Balke himself is VO2 = 6.5 + 12.5 x kilometers covered. Additionally, a formula by Horwill from 1994 can also be used: VO2 = 0.172 x (meters / 15 – 133) + 33.3. For more specific predicted VO2max scores, refer to the table provided in the original article.

Target Population:

The Balke 15-minute run can be adapted to suit most populations. For individuals who are unfit or unable to run, there are similar walking tests available as alternatives.

Reliability and Considerations:

The reliability of the Balke 15-minute run is dependent on factors such as practice, pacing strategies, and the motivation level of the participants. To ensure accurate results, it is recommended to address these factors. Additionally, like any field test, external conditions can influence the outcomes. Therefore, it is best to conduct the test on a day with minimal wind, no rain, and on a dry, smooth surface. For consistent and reliable results, try to replicate the test under similar conditions.


One of the significant advantages of the Balke 15-minute run is its scalability, allowing large groups to be tested simultaneously. Moreover, this test is incredibly cost-effective and straightforward to administer, making it accessible to a wide range of individuals.


The Balke 15-minute run does require some practice and pacing to achieve optimal results. Motivation also plays a crucial role as it can greatly impact performance during the test.
