Running economy — the oxygen cost of holding a given running pace — determines how hard a pace feels: use less oxygen and faster paces feel easier. It reflects biomechanics, muscle quality and coordination, and can be measured precisely in labs or approximated by modern wearables.

What running economy actually is

Running economy is a simple idea with complex causes. At its core it's the amount of oxygen your body needs to hold a particular speed. Use less oxygen and you can go faster for the same effort. Coaches often compare it to fuel mileage — a more economical runner will sustain a pace longer without needing extra fuel or slowing down.

That simplicity hides many moving parts. Running economy draws on biomechanics, muscle quality and coordination. So two athletes with the same VO2 max can still differ sharply in performance because one wastes less energy through inefficient movement.

How researchers and devices measure it

Measuring running economy usually means measuring oxygen consumption at steady paces. Labs use metabolic carts to record VO2 while a runner holds a set speed. Outside the lab, wearable tech offers proxies. Garmin’s running-economy metrics, for example, draw on several inputs — heart rate, stride length, ground contact time, vertical oscillation and step-speed loss — and often require a chest-strap heart-rate monitor to feed accurate data.

Those device metrics can be useful for trends. But they're not a perfect substitute for direct VO2 measures. Some elements of economy — tendon stiffness, the ability to store and return elastic energy, and muscle-fibre composition — don't show up on a watch. They're biological traits, partly trainable and partly genetic.

Training methods that actually improve economy

Research and coaches point to a handful of reliable interventions. None are magic. All require consistent work.

  • Build aerobic base: Increase low-intensity volume with genuinely easy miles. Higher easy-mileage trains the body to move efficiently; raising mileage by running harder can blunt gains and increase injury risk.
  • Add strides: Do short accelerations at the end of easy runs. Strides (relaxed, short bursts) teach faster leg turnover and better stride mechanics. Aim for a few after runs, two or three times weekly.
  • Strength training plus plyometrics: Strength work improves muscle quality and stability, reducing wasted motion. Plyometrics improve force generation and tolerance to rapid ground contacts. Progress gradually: start with pogo and squat jumps, then move to single-leg hops and bounds as strength and technique allow.

A 2024 meta-analysis in Sports Medicine found high-load strength training combined with plyometrics improves running economy among trained distance runners. Bottom line: build a steady aerobic base, add regular strides to reinforce technique, and include progressive strength and plyometric work — use wearables to track trends, but remember lab VO2 remains the gold standard.
