Have you ever wondered why two runners with seemingly identical aerobic capacities can achieve very different race times? We’re used to focusing on VO₂ max, often presented as the “limit” of our performance, but there’s another frequently overlooked factor that can make a real difference: running economy.
It’s not a magical concept, but a tangible and trainable aspect of your running. Imagine being able to run at the same pace with less effort or to hold a faster pace for longer. That’s exactly what running economy allows you to do. It’s not about being “fitter” in a generic sense, but about optimizing how efficiently your body uses oxygen to generate energy while running.

What Does “Running Economy” Really Mean?
Running economy is defined as the amount of oxygen required to run at a given speed. More simply, it reflects how efficiently your body uses oxygen.
A runner with good running economy can maintain a given speed while consuming less oxygen than a runner with poorer economy. Even a small difference just 2–4% can translate into a significant time gain in races, especially over longer distances such as the half marathon or the marathon.
Consider this: a 1% improvement in running economy in a marathon can save you several minutes! It’s not about “strength” or “endurance” in the traditional sense, but about optimal biomechanics and smarter energy use.
Physiological Facts: How Running Economy Influences Performance
To understand how to improve running economy, it helps to know what’s happening physiologically.
When you run, your muscles use oxygen to produce energy. If your running economy is inefficient, your muscles must work harder to generate the same amount of energy, wasting more of it as heat. This leads to greater overall energy expenditure, a faster rise in heart rate, and earlier fatigue.
Biomechanics plays a crucial role. An inefficient stride, poor posture, or improper foot strike can all contribute to suboptimal running economy. Muscle fiber composition also matters: a higher percentage of slow-twitch (Type I) fibers is generally associated with better running economy because these fibers use oxygen more efficiently.
Fortunately, these factors are not fixed they can be improved through proper training.
Practical Strategies: How to Improve Your Running Economy
Here are some concrete approaches you can incorporate into your training. The goal isn’t to change everything overnight, but to gradually introduce these elements while always listening to your body:
Low-Intensity Training
A significant portion of your training volume should be at low intensity, around 60–70% of your maximum heart rate. This type of work enhances metabolic efficiency and increases your muscles’ ability to use oxygen effectively. Never underestimate the power of slow, steady running.
Specific Strength Training
Strength training isn’t just about lifting weights. Focus on exercises that mimic running mechanics, such as lunges, skips, and plyometric jumps. These movements strengthen key running muscles (glutes, quadriceps, calves) and improve stability and power.
Improve Your Running Technique
A specialized coach can analyze your gait and identify areas for improvement. Small adjustments in posture, foot strike, and stride length can make a significant difference. Even recording yourself while running can reveal technical flaws to correct.
Flexibility and Mobility Work
Good flexibility and joint mobility allow for smoother, more efficient movement. Include dynamic stretching before runs and static stretching afterward. Specific mobility drills, such as hip rotations and ankle mobility exercises, can also be beneficial.
Listening to Your Body: The Secret to Lasting Results
Improving running economy takes time, patience, and attention to detail. Don’t expect immediate results. Listen to your body and adjust your training based on how you feel. Don’t be afraid to experiment with different techniques and strategies, but avoid overloading your system.
A well-balanced training plan combining aerobic conditioning, strength work, and respect for your individual characteristics is the key to unlocking your potential and running faster with less effort.
Remember: running economy is not a secondary factor it’s a fundamental element in maximizing your performance.
