Running form is the most-debated, most-misunderstood part of running technique. Most “perfect form” advice in the wider running world isn’t backed by the biomechanics literature. The Marathon Handbook running-form library covers what the data actually says about cadence, stride length, foot strike, posture, and breathing — and the small number of form changes that genuinely improve running economy.

The Honest Truth: 5 Form Rules That Actually Improve Running Economy
1. Higher cadence usually beats longer stride for economy
Heiderscheit’s landmark study showed that increasing step rate by 5–10% above habitual cadence reduces ground reaction forces, decreases knee load, and shifts contact point closer to the centre of mass — reducing braking forces and improving running economy1Heiderscheit BC, Chumanov ES, Michalski MP, Wille CM, Ryan MB. Effects of step rate manipulation on joint mechanics during running. Medicine & Science in Sports & Exercise. 2011;43(2):296–302.. The “180 spm” rule is a marketing simplification (Daniels observed it as average elite cadence, not as a target); the better rule is “5% higher than your current cadence” if your habitual rate is below ~170 spm.
2. Foot strike doesn’t matter as much as you think
Decades of research have consistently failed to show that any specific foot strike pattern (heel, midfoot, forefoot) is universally faster, more economical, or less injurious than the others2Almeida MO, Davis IS, Lopes AD. Biomechanical differences of foot-strike patterns during running: A systematic review with meta-analysis. Journal of Orthopaedic & Sports Physical Therapy. 2015;45(10):738–755.. What matters is the position of foot-strike relative to your centre of mass — overstriding (foot landing well ahead of body) is biomechanically inefficient regardless of which part of the foot strikes first. Don’t try to convert your foot strike pattern; do reduce overstriding via cadence work.
3. Strength work transfers to running economy
The most reliable, biggest-effect intervention to improve running form is heavy or plyometric strength training — typically 2–3% running-economy improvement after a 6–12 week strength block3Beattie K, Carson BP, Lyons M, Rossiter A, Kenny IC. The effect of strength training on performance indicators in distance runners. Journal of Strength and Conditioning Research. 2017;31(1):9–23.. The mechanism: improved leg-spring stiffness, better neuromuscular drive at footstrike, and reduced ground contact time. Two short heavy-strength sessions a week (squats, deadlifts, calf raises, plyos) outperform “running drills” alone for form improvement.
4. Running with a slight forward lean — from the ankles
The “lean from the ankles, not the hips” cue is one of the few form interventions with consistent evidence. Forward lean from the ankles places the centre of mass slightly ahead of the contact foot, which reduces braking forces at footstrike. Hip-pivot lean (bending at the waist) compresses the diaphragm, hurts breathing, and increases low-back load. The cue: imagine a string pulling you forward from the breastbone with the body straight from heel to crown.
5. The form fix that matters most: relaxed shoulders + arms
The single biggest form leak amateur runners have is upper-body tension — clenched fists, hunched shoulders, locked jaw. Tension wastes oxygen, restricts diaphragm range, and degrades stride symmetry. The cue you can use mid-run: every 5 minutes, drop the shoulders, unclench the fists (“hold a potato chip without crushing it”), and check the jaw. This is the form intervention you can actually deploy mid-race that materially affects pace.
Frequently Asked Questions
What is the best running cadence?
Most efficient running cadences for trained adults sit between 170 and 185 steps per minute, but the right cadence is individual and depends on your height, leg length, and running speed. The actionable rule: if your habitual cadence at easy pace is below 170 spm, increasing it by 5% reduces overstriding and ground reaction forces. If you’re already at 175+ spm at easy pace, you don’t need to change anything.
Should I land on my heel, midfoot, or forefoot?
Whatever your body naturally does — within reason. The literature consistently shows no foot-strike pattern is universally better. The thing to fix isn’t your foot strike, it’s overstriding (foot landing too far ahead of your body). Higher cadence + slight forward lean fix overstriding regardless of which part of your foot hits the ground first.
Are running drills worth doing?
Yes — high knees, butt kicks, A-skips, B-skips, and strides are inexpensive (5–10 minutes), produce small but real cadence and neuromuscular benefits, and double as warm-up. The biggest gains come from doing them consistently 1–2 times a week as part of warm-up before quality sessions, not as standalone workouts. Strength training in the gym still produces bigger form gains than drills.
Can I improve my running form by watching videos?
Marginally. Treadmill video at varied paces is a reasonable diagnostic — you can see overstriding, hip drop, cross-over gait, and excessive heel-strike from the side and back angles. But form change rarely sticks from video alone; it sticks when paired with a specific cue you rehearse during quality sessions until it becomes automatic.
Is barefoot running better for form?
For most runners, no. The evidence on barefoot/minimalist running shows it changes form (typically toward forefoot strike + higher cadence) but doesn’t reliably improve performance or reduce injury rates compared with conventional cushioned shoes. Transition is the main risk — bone-stress injury rates spike in the first 12 weeks of moving from cushioned to minimal shoes. If you want to experiment, start with strides on grass, not full runs.
