Running Economy Calculator

Formula

The formula to calculate the Running Economy (RE) is:

\[ RE = \frac{W \cdot T}{D} \]

Where:

\(RE\) 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)

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.

Example Calculation

Let's assume the following values:

Weight of the Runner (W) = 70 kg
Time Taken to Run the Distance (T) = 30 minutes
Distance Run (D) = 5 km

Using the formula to calculate the Running Economy (RE):

\[ RE = \frac{W \cdot T}{D} = \frac{70 \cdot 30}{5} = 420 \]

The Running Economy (RE) is 420 ml/kg/km.
