Definition and measurement

Running economy is the oxygen or energy cost of running at a given submaximal speed under specified conditions. It is not the same as pace, speed, technique or overall race performance. Comparisons require similar protocols because speed, gradient, environment, footwear, fatigue and measurement method can change the result.

Training and limits

Economy reflects interacting physiological, biomechanical and neuromuscular factors. Endurance, strength and plyometric programmes can affect it, but results vary by athlete and method. Evidence does not support one cadence, foot strike or posture for everyone. Change technique cautiously and assess response; no single drill or percentage improvement guarantees a HYROX® result.

FAQ

Is efficiency the same as speed?

No. It is cost at a specified submaximal speed.
