The 3 Most Common Running Form Mistakes and How to Fix Them

You’ve put in the miles, but your pace is stuck. Or perhaps a nagging pain keeps resurfacing. The problem likely isn’t your effort; it’s your form. Running is a skill, and subtle errors are often the difference between a personal best and a forced rest.

Correcting these flaws can unlock new speed, enhance efficiency, and banish chronic injuries. Here are the three most common culprits sabotaging your run.

1. The Overstride: Braking with Every Step:
The Mistake: Your foot lands well ahead of your body’s centre of mass. This acts as a brake, creating a jarring impact that travels up your leg.
The Fix: Shorten Your Stride. Focus on a quicker cadence. Your foot should land directly beneath your hips, not in front of them. Imagine running on hot coals.

2. The Posture Collapse: Running from a Chair:
The Mistake: A slight, unconscious sink of the hips, creating a “sitting” position while running. This deactivates your glutes and overloads your quads and knees.
The Fix: Run Tall. Imagine a string pulling the crown of your head toward the sky. Maintain a slight forward lean from the ankles, not the waist.

3. The Arm Cross-Over: Wasting Energy Side-to-Side:
The Mistake: Your arms swing across the centreline of your body. This rotational force counteracts your forward momentum, wasting precious energy.
The Fix: Drive Elbows Back. Keep your hands loose and your arms swinging like pendulums forward and back, not side-to-side. Your hands should not cross your chest.

“Running form isn’t about looking good; it’s about creating an efficient, resilient machine. A small technical fix can feel like a performance-enhancing drug.”
