Form fundamentals
Overstride Reach
How many centimeters ahead of your hips the foot lands at contact.
What it is
The horizontal distance between your ankle and your hips at the instant of touchdown, in real centimeters. Every runner lands slightly ahead of their center of mass — the question is how far.
Why it matters
The farther ahead the foot lands, the bigger the braking impulse and the more load the knee and shin absorb. Unlike the older percent-of-frames metric, this is measured only at the actual contacts, the way a gait lab does it.
How we detect it
We detect each initial contact per leg, measure ankle-to-mid-hip horizontal distance at that frame, and convert pixels to centimeters using your height (add it in Profile for true units).
How to fix it
Cadence first, always: shorter, quicker steps land closer to the body. If reach persists at a good cadence, look at hip extension — runners who can't finish behind reach out in front instead.
Recommended drills
- •A-skip drills (3x30m)
- •Metronome runs at +5-8% cadence
- •Butt kicks (3x30s)
Run these 2-3x per week. Expect to feel a change in form 4-6 weeks in.
