TL;DR
- Cadence is steps per minute. It is a proxy for how much you overstride and how much impact you take.
- Do not chase 180 spm as a magic number. Aim for a better trend relative to your own baseline.
- A practical target is adding 5-10% on easy runs if your cadence is consistently low.
- The fastest way to improve cadence is not "move your legs faster". It is shorter steps + similar effort.
- Century helps by tying cadence changes to recovery, so you do not force form changes on a tired body.
What cadence is and why it matters
Cadence is the number of steps you take per minute (spm). Most watches estimate it using wrist motion plus pacing data, and it is usually accurate enough to spot patterns.
Why coaches like it:
- Lower cadence often comes with longer stride length and more braking (overstriding).
- Overstriding usually means higher impact on the same pace.
- Cadence tends to drop when you are fatigued, which can be an early warning sign.
Runner's World recently called cadence one of the most underrated watch metrics and highlighted research suggesting that increasing cadence by 5-10% can lead to biomechanical changes linked to reduced stress on the tibia, knee, and hip.
The 180 spm myth (and the better way to think)
You will hear "180 steps per minute" everywhere. It is not useless, but it is also not a law of nature.
A better framework:
- Your cadence depends on speed. It will be lower on easy runs and higher on intervals.
- Your body size and mechanics matter. Taller runners often sit a bit lower at the same effort.
- Trends beat snapshots. A single run is noisy. A month of easy runs tells the truth.
A good goal is not "hit 180". A good goal is:
- get above obvious red flags (for many runners, consistently near 150 spm on easy runs)
- maintain a stable cadence when effort is steady
- avoid the fatigue cliff where cadence collapses late in a run
How to read cadence from your watch (Apple Watch included)
Most platforms show cadence per run plus charts over time.
What to look for:
- Easy runs: pick one recurring route. Compare cadence only on similar terrain.
- Long runs: check whether cadence falls in the last third.
- Hills: do not judge cadence on steep hills. Focus on effort.
If your app lets you see cadence during the run, do not stare at it. Use it as a gentle nudge, not a live scoreboard.
A safe cadence improvement plan (2 weeks)
If you want to experiment, do it like an engineer: one variable at a time.
Step 1: find your baseline
Pick 3-5 easy runs and note the cadence range when you feel relaxed.
Example:
- baseline easy cadence: 158-164 spm
Step 2: add 5% (not 20 spm)
Take the midpoint of your baseline and add 5%.
- baseline midpoint: 161 spm
- 5% increase target: ~169 spm
That is enough to change mechanics without forcing a new running style.
Step 3: use short drills, not whole runs
Add 4 x 30 seconds of slightly quicker turnover into an easy run, with 60-90 seconds easy between.
Cues that work:
- "Run over hot coals"
- "Quicksand" (get off the ground quicker)
- "Shorter steps, same effort"
Do this 2-3 times per week for two weeks. Recheck cadence trends.
Common mistakes that make cadence work backfire
- Forcing cadence when you are cooked
If your recovery is low, your coordination is worse. That is when forced changes can annoy your calves and Achilles.
- Only moving your feet faster
If you increase cadence without shortening your stride, you just spin more and burn more energy.
- Changing everything at once
New shoes, new training plan, and a form overhaul in the same week is a classic recipe for a niggle.
- Comparing cadence to other people
Cadence is personal. Compare you to you.
A simple benchmark: cadence vs pace
Try this thought experiment.
If you run the same pace on two days, but one day has lower cadence and higher heart rate, that often means:
- you are tired
- you are overstriding
- or conditions were harder (wind, heat)
Cadence alone does not solve it, but it is a useful breadcrumb.

Where Century fits
Most runners try to change form on the days they feel motivated. The better strategy is to change form on the days your body is ready.
Century connects your cadence trends with recovery signals like sleep, resting heart rate, and HRV so you can:
- experiment with cadence on high readiness days
- spot fatigue patterns when cadence drops late in runs
- avoid forcing technique changes when your body is under-recovered
