Running cadence: what it really means and why 180 steps isn't a rule

14 July 2026 · The science of running · 7' read

If you own a running watch — Garmin, Coros, Polar or Apple Watch — you've seen it: "Cadence: 164". And if you've searched around online, you've probably run into the "advice" that the right number is 180 steps per minute. So what is cadence, how does it relate to stride length — and does one number really fit everyone?

What is cadence?

Cadence (or step rate) is simply how many steps you take in one minute, counting both feet. You'll often see it as "spm" (steps per minute).

You don't even need a watch to measure it: at an easy, steady pace, count how many times your right foot lands in 30 seconds and multiply by 4. If you counted 21, your cadence is 168.

For a frame of reference, recreational runners' cadence can vary quite a lot. It usually rises as speed increases, which is why a single number only makes sense when you look at it together with the running pace and the characteristics of that specific runner.

Cadence and stride length: the two halves of speed

Cadence is only half of the equation. The other half is the length of each step — the distance you cover from one foot's contact with the ground to the next. Most modern watches (Garmin, Coros, Polar, Apple Watch) calculate both your cadence and the length of each step automatically, which they often show as "stride length" — even though in strict biomechanical terms a full stride includes two steps. The relationship couldn't be simpler:

Speed = step rate × length of each step

This has a consequence that explains almost the entire cadence debate: two runners can run at exactly the same pace with completely different cadence — one with quick, shorter steps and the other with slower, longer ones. Neither of them is doing it "wrong".

Where did the "magic 180" come from?

The legendary coach Jack Daniels watched runners at the 1984 Olympic Games and counted their steps: nearly all elite distance runners were running at about 180 steps per minute or more. The observation was correct — turning it into a "rule for everyone" was not.

Those elites were running at race speeds, far faster than your easy runs. Cadence depends on speed, height, leg length and each runner's technique — and, to a lesser degree, on experience and running economy. A tall runner at an easy pace may be perfectly fine at 165 — while a shorter one naturally sits at 178.

Why it matters: when your step acts like a brake

The real problem isn't the number on your watch — it's overstriding: when your stride is too long, your foot lands well in front of your body with a nearly straight knee. That means the landing happens well in front of your body's centre of mass. Every such footstrike acts like a small brake and can increase braking forces and some of the loads your joints absorb.

This is where science has something very specific to say. The Heiderscheit study (2011), at the University of Wisconsin, showed something interesting: researchers asked 45 runners to run at the same speed, but with slightly quicker steps.

Increasing cadence by 5% and 10%, at the same speed, reduced specific loads at the knee and hip. And later reviews found similar results: when cadence rises at the same speed, step length, vertical bounce and some of the loads the joints absorb usually go down.

How to improve it — if you need to

First things first: if you run pain-free and your foot lands close to your body, you don't need to change anything — your "natural" cadence is just fine. But if you overstride, struggle with knee niggles, or simply want smoother form, a reasonable first try is about +5% over your current cadence — not a leap straight to 180. If you're at 160 today, you could try around 168 steps per minute.

One trap: cadence changes with speed

The faster you run, the higher your cadence naturally climbs. That's why it makes no sense to compare your tempo-run cadence with your easy-run cadence — or your number with another runner's of a different height. Compare yourself to yourself, at the same pace — exactly as you do with your heart-rate zones.

And a dose of honesty, as always: small increases in cadence can reduce some of the loads at the knee and hip when speed is kept the same. The most recent systematic review found fairly strong evidence for specific biomechanical changes, but no definitive proof that changing cadence prevents injuries in general or always improves performance — the most encouraging data concern runners with kneecap pain. It's a promising tool, not a magic wand.
