The Problem: About Half of All Runners Get Hurt Every Year

Running has one of the highest injury rates of any endurance sport. A 12-month prospective study of recreational runners found that 51% sustained a running-related injury over the year. The advice most of them get is the same three things: rest more, stretch more, buy different shoes.

Almost nobody says: let's look at how you're actually running.

That is strange, because every other sport treats technique as fundamental. Swimming starts with stroke mechanics. Golf starts with grip and swing plane. Tennis starts with the forehand. Running starts with nothing. You lace up and go.

The Evidence: A 62% Lower Injury Rate in the Trial That Anchors This

GaitLab's method is built on published gait-retraining research rather than opinion. The anchor study is the strongest one in the category.

Chan et al. (2018), American Journal of Sports Medicine: a randomized controlled trial of 320 novice runners. Gait retraining with real-time feedback on impact loading produced a 16% injury rate at 12 months, against 38% in the control group. That is a 62% relative reduction.

The caveats belong here too. That trial ran on novice runners. The intervention targeted impact loading specifically, not arbitrary form changes. A phone is an imperfect stand-in for lab-based feedback. What carries over is the signal: small, specific, targeted changes to running form lower injury risk.

The wider literature points the same way:

  • A 5–10% cadence increase reliably reduces impact loading (Sports Health, 2025 systematic review).
  • Overstriding, where the foot lands well ahead of the pelvis, drives braking force and impact loading.
  • A gait-retraining meta-analysis found meaningful changes in kinematics and kinetics, and reduced pain and injury occurrence, across distance runners (Bramah et al., JOSPT 2022).
  • Specificity is what works. Multi-cue interventions degrade adherence and outcome. One runner, one or two prioritized changes, tied to the tissue that actually hurts.

The App: Four Things That Set It Apart

GaitLab Coach is not a fitness tracker. Four things define it:

1. The research is on the page

Every recommendation traces back to a citation you can open and read. The evidence base is surfaced in-app under "The Science", linked from the home screen footer.

2. Injury context

It asks where you hurt before it analyzes anything. There are 16 named conditions: runner's knee, IT band syndrome, shin splints, plantar fasciitis, Achilles tendinitis, and 11 more. You can flag up to 4. The findings, drills, and the things to avoid all shift based on what you flagged.

3. Findings anchored to frames

Each finding carries a severity tag (HIGH, MEDIUM, or LOW) and a timestamp pointing at the moment in your video it came from, so you can go look. A typical one reads "right arm crosses midline at [email protected]."

4. What the unlock adds

An elite-runner radar comparison, Ask Coach (5 follow-up questions grounded in your own analysis), and a 4-week corrective plan built from what your video showed. Same evidence base throughout.

This Blog

The articles here are evidence-based guides, written for you to apply to your own running. Each one takes a single pattern, such as overstriding, hip drop, crossover gait, or a cadence that sits too low, and explains what it does to the tissue underneath, how to spot it in a video you film yourself, and what the research says about changing it.

They are not personal stories, and they are not case studies of individual runners. Where a number appears, it is linked to the study it came from. Where the evidence is thin or mixed, the article says so rather than rounding it up into a promise.

One thing worth stating plainly: this is form analysis, not a medical opinion. GaitLab flags movement patterns. It cannot tell you what is wrong with a specific tissue, and a persistent or worsening pain is a reason to see a physio or a doctor, not a reason to keep adjusting your stride.

If you have a recurring ache, a pace that has not moved in months, or a form issue somebody mentioned once and never explained, there is probably something useful here.
