Enter the distance run, the time taken, and your weight into the calculator to determine your running economy. Running economy is a measure of how much oxygen you use to travel a certain distance while running.
Running Economy Formula
The following formula is used to calculate the running economy:
RE = (W * T) / D
Variables:
- RE is the running economy (ml/kg/km)
- W is the weight of the runner (kilograms)
- T is the time taken to run the distance (minutes)
- D is the distance run (kilometers)
To calculate running economy, multiply the weight of the runner by the time taken to run the distance and then divide by the distance run.
What is Running Economy?
Running economy is a measure of efficiency, indicating how much oxygen a person consumes while running at a certain pace. It is often measured in milliliters of oxygen consumed per kilogram of body weight per kilometer (ml/kg/km). A lower value indicates better economy, meaning the runner can maintain a given speed while using less oxygen, which is advantageous for endurance performance.
How to Calculate Running Economy?
The following steps outline how to calculate Running Economy.
- First, determine the weight of the runner (W) in kilograms.
- Next, determine the time taken to run the distance (T) in minutes.
- Next, determine the distance run (D) in kilometers.
- Next, gather the formula from above = RE = (W * T) / D.
- Finally, calculate the Running Economy (RE) in ml/kg/km.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Weight of the runner (W) = 70 kilograms
Time taken to run the distance (T) = 50 minutes
Distance run (D) = 10 kilometers
