You need to train smarter.
Speed isn't always a fitness problem. It's a movement problem. The runners who break through stop training the engine and start fixing the chassis.
88%
of new runners get hurt in their first three years.
Most of those injuries trace back to form, not mileage. The catch is you can't watch yourself run, and the people around you aren't trained to see it.
£140
is what the nearest gait lab charges for an hour.
Reflective markers, a treadmill, eight cameras, a six-week wait. The reading is excellent. Almost nobody actually gets one.
10 seconds
of phone footage. Same diagnosis the lab gives you in two hours.
Pose models on a phone now do the work eight cameras did five years ago. The £140 reading became something you can take this afternoon.
How it works Three steps,
Three steps,
thirty seconds.
We watch the footage so you don't have to. The reading you'd get from a lab, in the time it takes to lace up.
We watch the footage and pick the one thing worth working on. You just film.
ANALYSING

We analyse it
Pose estimation. Thirty-three landmarks, thirty times a second. The same six measurements running biomechanics research ties to injury and economy.

Will my video be safe? I hate being on camera.
We never share it, never train on it, and nobody but you ever sees it. The pose data we keep is anonymous joint coordinates.
I'm not a serious runner. Is this even for me?
Especially yes. The runners who get the most from Gaitor are three months in, before bad habits set. Every reading comes back in plain English: "your head is tilted thirty-three degrees forward, which is why your neck aches at mile four." No jargon. And yes, the app launched today, so you're early. That's why the first reading is free.
Can I film on a treadmill instead of outside?
Yes. Treadmill runs work as well as outdoor runs, sometimes better — easier to get a clean side-on angle. Just set the phone on a tripod or shelf level with your hip.
How is this different from Strava's running power?
Running power estimates effort. Gaitor measures form. They're complementary — Strava tells you how hard you're working, Gaitor tells you whether your body is doing it efficiently.
What if my form score is bad? Should I stop running?
No. A score is a snapshot, not a verdict. The cue we surface is the highest-leverage change you can make on your next run. Most runners see meaningful score movement inside three weeks.
Does it work for trail running, sprints, ultras?
Best for steady-state road or treadmill runs at conversational pace — that's where the biomechanics research is strongest. Trail and sprint readings are coming.
Can I cancel anytime?
Yes, in App Store settings. We don't make you call anyone or fill in a form. The Plan also comes with a refund if your form score hasn't moved after six weeks of weekly readings.
One reading is free.
