Running economy consists of many physiological and biomechanical factors that contribute to running performance, and is measured to quantify energy utilization in the human body while running at an aerobic intensity.[1]: 33 [2]: 465 [3] Oxygen consumption (VO2) is the most direct method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects metabolism. To allow for comparison between people of various sizes, values that are relative to body mass are traditionally used. However, applications of this practice have proven misleading due to the low correlation between sub-maximal VO2 and body mass.
Among two other values (VO2max & Lactate threshold), some experts consider running economy to be a valid indicator of performance in distance running events.

The measure of energy expended while running aerobically at some submax speeds is a measure of running economy.

Running economy (RE) is typically defined as the energy demand for a given velocity of submaximal running, and is determined by measuring the steady-state consumption of oxygen (VO2) and the respiratory exchange ratio.

Measuring someone's running economy is equivalent to asking the question, "How far can this person run using a given amount of energy?" Energy use is usually reported in terms of oxygen consumption; the farther the person can run per unit of oxygen consumed -- or, stated another way, the less oxygen he/she consumes in running a given distance -- the more economical he/she is.
