Cadence
Understand why cadence is one of the most important metrics for running faster with fewer injuries.
What is cadence.
Running cadence is the number of steps (or strides) per minute (spm). It is one of the most studied biomechanical metrics in sport and has a direct impact on efficiency, speed and injury risk.
Jack Daniels observed in his classic studies that most elite Olympic runners ran around 180 spm or more. This number became a reference — but not an absolute rule.
Runners with low cadence (below 160 spm) usually have strides that are too long (overstriding), which increases impact on the knees and hip and wastes more energy.
Why improve cadence.
Less impact
Shorter, faster strides reduce the impact force at each landing — less stress for knees and ankles.
Greater efficiency
Smaller strides landing under the center of gravity better utilize the elastic energy of the muscles.
More speed
Speed = cadence × stride length. Improve cadence without sacrificing stride = more speed.
Improved posture
Higher cadence naturally induces landing closer to the center of mass, improving overall posture.
How to improve step by step.
1. Measure your current cadence
Run for 60 seconds and count the times only one foot touches the ground — multiply by 2. Your Garmin/Polar also records automatically.
2. Use a metronome
Free apps (Metro Timer, Metronome Beats) let you set BPM. Start 5 spm above your current cadence.
3. Gradual progression
Increase only 5-10 spm at a time. Your body needs 4-6 weeks to adapt to the new biomechanics.
4. Technique drills
Skipping, butt kicks and gentle downhill running naturally promote faster, more efficient stride.

The biomechanics of cadence.
Jack Daniels, in his classic study of the 1984 Olympic Games, observed that all elite runners — regardless of pace — held cadences above 180 spm. That observation sparked decades of research into why higher cadences are biomechanically superior.
Physics explains it: at low cadences with long strides, the foot lands ahead of your center of gravity, creating a 'brake' with every step. That braking impact travels through the ankle, knee and hip. Vertical impact force can reach 3x your body weight.
With a higher cadence and shorter strides, the foot lands closer to your center of gravity. The impact angle reduces the braking component, vertical force drops and the elastic energy in your tendons is used more efficiently — less energy spent per km.
Truths and myths about cadence.
Increasing my cadence will make me slower
At first, yes — you shorten your stride before compensating with stride turnover. After 4-6 weeks of adaptation, the combination of shorter, more frequent strides delivers equal or greater speed at a lower energy cost.
I should change my cadence at every pace
Cadence naturally rises with pace. The goal isn't a constant 180 spm — it's avoiding overstriding at any pace. At an easy pace, 160-170 spm is completely normal.
Carbon shoes fix overstriding
No. Carbon plates increase elastic energy return, but they don't correct fundamental biomechanics. A runner who lands with the leg extended out front will waste energy no matter the shoe.
