What is the relationship between cadence, stride, and pace?

Running speed equals stride length multiplied by cadence. Given your pace (and therefore speed) and one of the two, the third is fixed, so the tool solves whichever you leave out.

Is stride length per step or per full stride?

Here it is the per-step distance, from one footfall to the opposite footfall, which is the convention most GPS watches report. A full gait cycle is two steps, so double the figure if you need that definition.

What is a good running cadence?

Many coaches target roughly 170 to 185 steps per minute to reduce overstriding and braking forces. There is no single ideal number, though — optimal cadence is individual and naturally rises as you run faster.

How can increasing cadence help my running?

At a fixed pace, a higher cadence means shorter steps, which usually reduces overstriding, vertical bounce, and impact at the knee. Small, gradual increases of a few percent are easier to sustain than large jumps.

Why does my watch show a different stride length?

Watches estimate stride from cadence and GPS or accelerometer speed, so measurement noise and the per-step versus per-stride convention can cause small differences from a clean calculation like this one.

Connect pace, cadence, and stride length

Cadence and stride length are the two levers that produce your running speed, and understanding the trade-off between them is central to improving running economy. This tool makes the relationship concrete: tell it your pace and either your cadence or your stride length, and it solves for the missing number — so you can see exactly how a cadence change would shorten your steps, or how lengthening your stride raises your cadence demand.

How it works

The governing equation is simple and exact:

speed (m/min) = stride length (m) * cadence (steps/min)

Your pace gives speed directly, since speed = 1000 / pace in metres per minute when pace is in minutes per km. With speed known, the tool rearranges for whichever variable you left blank:

cadence       = speed / stride length
stride length = speed / cadence

It also reports your speed in km/h and flags cadences that fall outside the typical 160 to 190 steps-per-minute range so you can spot likely overstriding or unusually choppy form.

Tips and notes

Stride length here is the per-step distance, matching the figure most running watches display — if your source uses the full two-step gait cycle, double the value before comparing. Use the tool to plan deliberate form work: hold your pace constant, nudge your cadence up by a few percent, and watch your stride shorten correspondingly, which is the safe way to reduce braking forces without suddenly straining. Chasing a single “magic” cadence is a mistake; the right number is the one that feels economical for you, and it should drift higher as your pace quickens.
