Concept
Stride length
The distance covered with each step as the runner moves forward. Devices may use stride and step terminology differently.
How it connects to cadence
Cadence and distance per step combine to create speed. At the same pace, a small cadence increase generally requires a slightly shorter step.
Why longer is not always better
A longer step can come from stronger propulsion, but reaching the foot far ahead may create braking rather than useful speed.
Why the number changes
Faster pace, hills, surface, fatigue, strength, and mobility all affect distance per step.
How to use it
Use stride length with cadence and pace to understand how speed changes, not as a standalone target to maximize.
Common misconception
Trying to force a longer stride does not guarantee faster running and may increase braking.
