Is there a "right" way to run?
If you have ever looked for technique tips, you probably ran into promises of running "lighter", "impact-free" and "injury-free" just by reprogramming your stride. Two popular methods anchor this idea: the Pose Method, created by sport scientist and former Olympic coach Nicholas Romanov in the former Soviet Union, and Chi Running, by ultramarathoner Danny Dreyer, inspired by tai chi principles. Both emphasize a slightly forward-leaning trunk, landing under the body and using gravity to "fall" forward.
The intention is good. The problem starts when these methods are sold as universal truth. Modern biomechanics shows that technique matters, but in a more specific and less magical way than the marketing suggests. Let us separate what evidence supports from what is just intuition.
Cadence: the adjustment with the best evidence
Of all the elements of running form, slightly increasing cadence (the number of steps per minute) is the one with the most consistent scientific backing. The logic is direct: for the same speed, more steps mean shorter steps, the foot lands closer to the center of mass and the braking force at each contact decreases.
Notice that the gain comes from a subtle adjustment, in the range of 5% to 10%, not from a stride revolution. Evidence indicates that unloading knee and hip this way may help prevent and manage common running pains. If you feel persistent discomfort, talk to a professional before changing anything.
The myth of 180 steps per minute
The number "180 spm" became dogma, but its origin is an observation, not a prescription. Coach and physiologist Jack Daniels counted the cadence of elite runners at the Los Angeles Olympics, in 1984, and noticed that almost all in the distance events were turning over at 180 steps per minute or more.
The detail that gets lost: these were elite athletes, at race pace. For the common runner, at slower paces, the optimal cadence is usually lower and varies with pace, terrain and height. What matters is not hitting a round number, but where the foot lands. A runner at 165 spm landing under the body may be more efficient than another at 180 spm still overstriding.
Overstriding: the real villain
Here technique truly weighs. Overstriding is landing with the foot well in front of the center of mass, generally with the leg extended and the heel jammed into the ground. This creates a braking phase with every step, increases peak load and wastes energy pushing you backward before moving forward.
The good news is that increasing cadence usually corrects overstriding automatically: shorter steps naturally bring the contact point under the hip. You do not need to think about "forefoot striking", just about not stretching the leg too far out in front.
Is forefoot striking better? The evidence says "it depends"
Perhaps the biggest confusion lives here. Forefoot running became synonymous with "running correctly", but systematic reviews do not support that promise. There is no strong evidence that forefoot striking is more economical or universally safer than rearfoot striking.
In other words: switching foot strike is transferring stress from one tissue to another, not making it disappear. For those with no pain or performance problem, forcing a foot strike change rarely justifies the risk.
Why overhauling the whole stride can be expensive
The Pose Method case is revealing. A controlled study followed triathletes through 12 weeks of formal training in the method, comparing against a control group.
Translating: the stride looked "prettier" on paper, but the athletes started spending more energy to run at the same pace. Global technique overhauls usually have this side effect in the short and medium term, because the body had already optimized its own movement over years.
What biomechanics really teaches
Researcher Benno Nigg, from the University of Calgary and a world reference in footwear biomechanics, proposed a paradigm shift. After decades of data, he argues that the old "impact control" and "pronation control" models do not hold, and suggests two concepts: the preferred movement path and the comfort filter.
The central idea is that each body has its own movement trajectory, and the organism tends to defend it. Studies show that changes in shoes, insoles or orthotics alter the skeleton's kinematics very little, because the musculature "tunes" itself and returns the movement to its usual path. Comfort, in this reading, works as a filter that brings you closer to your ideal pattern.
The practical message is humble and liberating at the same time. Studies suggest that:
- Cadence is the most reliable dial: adjustments of 5% to 10% unload knee and hip.
- Overstriding is worth correcting, and cadence solves it almost alone.
- Foot strike pattern rarely needs to be changed on purpose in those without pain.
- Total overhauls of form may worsen economy before improving it, if they improve it at all.
Methods like Pose and Chi contain good isolated tips, above all about landing under the body. But turning the whole run into a reengineering project usually yields less than small, specific changes. Before any technique change, especially in the face of recurring pain, talk to a professional who can assess your movement.
