Runners often confuse stride length with range of motion. One measures movement; the other enables it. Knowing the difference changes how you run.

What Is Overstriding in Running Overstriding in running occurs when the foot lands too far in front of the body’s center of mass.This creates braking forces that slow forward movement and disrupt efficient mechanics.In efficient running, the foot lands under the body during support rather than ahead of it. The idea of landing ahead of the body seems simple, yet confusion still surrounds the term. If someone tells you that you’re “overdoing” something – which is essentially what overstriding implies – you might ask: how do you know? Maybe I’m just doing it differently. Who decides what is too much?…
