What It Is

Your stride, mapped in 3D.

Running form feels natural, but it’s rarely optimal. Years of desk work, old injuries, and stress all leave their mark on a stride, and once a movement pattern is learned, stretching and strengthening alone usually won’t change it.

Run Lab uses 3D Gait Analysis, gold standard technology that has historically only been available to professional athletes, to see exactly what’s happening at your foot, knee, hip, and trunk while you run, with live feedback in real time.

That data feeds directly into your plan: both the training changes and the hands-on treatment. Founder John Salva is a Certified Running Gait Analyst (Level 1 & Level 2) and Certified Endurance Running Coach. The read on your stride comes from real training, not a guess.

Why Get A 3D Gait Analysis

Three reasons runners choose Run Lab.

Reduce Injuries

Reducing the stress of each step by just 10% can help you run twice as far before your body breaks down. A form change can help get you there.

Improve Performance

Running form drives running economy, one of the biggest predictors of performance. Improving your running economy by 5% leads to roughly a 3.8% improvement in distance events: a 4-hour marathoner can save 9+ minutes.

Love Every Run

Find a form that works for you and running often feels easier and more enjoyable, because your body does less work for the same result (or a faster one).

The Technology

RunDNA 3D technology, built for runners.

Most attempts to fix a stride use a cookie-cutter method, or throw so many cues at you at once (land on your mid-foot, lean forward, drive your knees, relax your arms) that your brain can’t process it mid-run. 3D Gait Analysis works differently.

RunDNA 3D technology compares your numbers and angles against established norms in real time, and categorizes your gait, overstrider, collapser, bouncer, weaver, and more, so we know exactly which pattern we’re working with.

From there, we land on one simple cue that makes the biggest impact for you, paired with drills that progress from slow and deliberate to fast and running-like. Your results and personalized training calendar live in the RunDNA app, so the plan travels with you.

What It Helps

Where your stride tells the story.

If pain only shows up when you run, the cause is often in how you run.

Questions, Answered

Run Lab, no mystery.

Not at all. Run Lab works for brand-new runners and lifelong ones alike. Whatever your pace or mileage, the same frame-by-frame process finds the patterns worth addressing.

Wear whatever you’d normally run in, including your usual running shoes. If you rotate between a few pairs, feel free to bring them too: shoe differences can change your stride.

It depends on your plan: gait analysis is sometimes billed differently than a standard PT visit. We verify your exact benefits before your first session, so there’s no surprise on your bill. Questions before then? Call us at (570) 319-6903.
