What Is Running Economy — and Why Does It Matter?

Introduction

When runners talk about performance, metrics like VO₂max, pace or heart rate are often the main focus.

 

Another concept, however, is increasingly discussed in endurance training: running economy.

 

Running economy is generally used to describe how efficiently a runner uses energy at a given pace. In simple terms, it reflects how much effort is required to maintain a certain speed.

 

Rather than focusing only on maximum capacity, running economy looks at how efficiently that capacity is used.

 

What Is Running Economy?

Running economy is often defined as the amount of oxygen or energy a runner uses at a specific pace.

 

Two runners may have similar fitness levels, but if one uses less energy to maintain the same speed, that runner is considered more economical.

 

This can make a meaningful difference, especially in longer races where small inefficiencies can accumulate over time.

 

Why It Matters in Endurance Performance

In endurance sports, performance is not only about how much energy you can produce, but also how efficiently you use it.

Even small improvements in efficiency may allow runners to:

• maintain pace with less effort
• delay fatigue
• sustain performance over longer distances

For this reason, running economy is often discussed alongside other factors such as VO₂max and lactate threshold.

 

What Influences Running Economy?

Running economy is influenced by a combination of physiological and mechanical factors.

 

Some commonly discussed aspects include:

 

1.Running technique: Posture, stride mechanics and coordination can influence how efficiently force is applied and how energy is transferred during each step.

 

2. Cadence and rhythm: Consistent rhythm and cadence may contribute to smoother movement patterns and reduced unnecessary motion.

 

3. Strength and stiffness: Muscle strength and tendon stiffness can influence how effectively energy is stored and released with each step.

 

4. Neuromuscular coordination: Efficient movement patterns depend on how well the body coordinates different muscle groups during running.

 

Can Running Economy Be Improved?

Running economy is not a fixed trait and may change over time with training.

 

Different approaches are often discussed, including:

 

1. Consistent aerobic training: Regular running helps develop movement patterns and efficiency over time.

 

2. Running drills: Short coordination and technique drills are sometimes used to reinforce efficient movement and rhythm.

 

3. Strength training: Targeted strength work may support force production and stability.

 

4. Strides and faster running: Short faster efforts can help improve coordination and running mechanics at higher speeds.

 

Running Economy and Technique

As fatigue builds during longer runs, running mechanics may gradually change.

 

Small variations in posture, cadence or coordination can increase the energy cost of running.

 

For this reason, some coaches consider technique and coordination an important part of maintaining efficiency over time.

 

A Concept Worth Understanding

Running economy is not always directly visible or easy to measure for recreational runners.

 

However, it represents an important idea: how efficiently you move while running.

 

Rather than focusing only on speed or intensity, it may be helpful to consider how smoothly and efficiently that speed is maintained.

 

Understanding running economy can offer another perspective on endurance performance and training.
