What Is Running Economy and How to Improve It

If you’ve ever watched elite runners and marveled at their seemingly effortless speed, you’re witnessing excellent running economy in action. It’s a crucial, yet often overlooked, component of performance that sits alongside VO2 max and lactate threshold. While VO2 max sets your aerobic ceiling and lactate threshold determines your sustainable intensity, running economy dictates how much of that capacity you waste with each stride. Simply put, it’s the fuel efficiency of your running body. For runners of all levels, learning how to improve running economy is one of the most effective ways to get faster without necessarily getting fitter in the traditional sense. It’s about making better use of the fitness you already have.

What Is Running Economy?

Running economy is formally defined as the amount of oxygen (or energy) you consume to maintain a specific, sub-maximal running speed. Think of it as your body’s miles-per-gallon rating. A runner with good economy uses less oxygen to run an 8-minute mile than a runner with poor economy running at the same pace. This efficiency translates directly to performance: with less energy wasted on unnecessary movement, more is available to propel you forward, allowing you to hold a faster pace longer or finish a race with more in the tank. It’s influenced by a blend of physiological factors (like muscle fiber type and cardiovascular function) and biomechanical factors (your running form and technique). While some aspects are genetic, many are highly trainable.

Key Factors That Influence Running Economy

Your efficiency is shaped by several interconnected elements. Understanding these helps target your training.

• Biomechanics (Form): This is how you move. Excessive vertical oscillation (bouncing), overstriding (landing with your foot too far in front of your body), and side-to-side arm swing all waste energy that could be used for forward motion.
• Muscle Strength and Stiffness: This might sound counterintuitive, but your legs need to act like springs. Stronger muscles, tendons, and connective tissues can store and return more elastic energy with each footstrike, reducing the metabolic cost of running. Weakness, particularly in the hips and glutes, leads to instability and compensatory movements that hurt economy.
• Neuromuscular Coordination: This is your brain’s ability to efficiently recruit the right muscles at the right time. Better coordination leads to smoother, more fluid strides.
• Anthropometry: Body composition matters. Carrying excess non-productive mass (body fat) increases the energy cost of running. Limb length and distribution can also play a small role.

How to Improve Running Economy: Actionable Strategies

Improving your efficiency requires a consistent, multi-faceted approach. Focus on these key areas.

1. Refine Your Running Form

You don’t need to force a perfect, robotic stride, but subtle adjustments can yield big savings. Work on one cue at a time during easy runs.

• Increase Cadence: A quicker, lighter turnover often reduces overstriding. Aim for a cadence that feels natural but quick; you can learn more about this in our guide to running cadence.
• Land Under Your Center of Mass: Try to have your foot strike the ground beneath your hips, not stretched out in front. This promotes a more stable, efficient landing.
• Run Tall and Relaxed: Maintain a slight forward lean from the ankles, not the waist. Keep your shoulders relaxed and your arms swinging forward and back, not across your body.

2. Build Functional Strength

Strength training is non-negotiable for better economy. It builds the spring-like stiffness and stability you need. Prioritize exercises that mimic running’s single-leg, dynamic nature.

For a complete routine, see our list of essential strength exercises for runners.

3. Perform Specific Workouts

Certain runs teach your body to be economical at faster speeds. Always warm up thoroughly before these sessions.

These workouts complement the foundational mileage and endurance building covered in our article on how to build running endurance.

Frequently Asked Questions (FAQ)

Can I improve running economy without running more miles?

Yes, to a significant degree. While consistent running builds a base of specific fitness, the strategies outlined here—form work, strength training, and specific workouts like strides and hills—can dramatically improve your economy without necessarily increasing your total weekly mileage. Quality often trumps quantity for this specific goal.

How long does it take to see improvements in running economy?

Neuromuscular improvements from form drills and strides can be felt within a few weeks. Strength gains that translate to more powerful, springy strides typically take 6-8 weeks of consistent training. Be patient and consistent; economy is a long-term project that pays off in lasting performance gains.

Does losing weight improve running economy?

Generally, yes, because you have less non-propulsive mass to carry. However, the focus should be on healthy, sustainable fat loss while preserving or building lean muscle mass. Drastic weight loss or being underweight can harm performance, health, and injury resistance. For personalized nutrition advice, consult a registered dietitian.

Is running economy the same as efficiency?

In common running parlance, they are used interchangeably. Technically, running economy is the measurable metric (oxygen cost at a speed), while efficiency is the broader concept of performing with minimal wasted effort. Improving your economy is the quantitative result of becoming a more efficient runner.

How does running economy relate to mental endurance?

When your body runs more economically, it feels easier. This positive physical feedback is a huge mental boost. Knowing you are moving efficiently can build confidence and reduce the perceived effort of a hard pace, which is a key component of building mental endurance for long distance running.
