Show that it changed, instead of saying so
Your athlete has heard for two months that the stride is too long. Two measurements eight weeks apart say more than saying it ten more times.
The measures you can actually coach
Not everything measured is trainable. These are, and they respond to a cue within a single session.
- 1
Cadence
The fastest-moving measure and the one that drags others with it: a higher cadence at the same speed shortens the stride and reduces overstride by itself. Always measure at the same speed, or you are comparing two different things.
- 2
Overstride
The horizontal ankle-to-pelvis distance at initial contact, as a percentage of leg length. This is the number behind "you are landing too far in front".
- 3
Contact and flight time
Per leg. The left-right difference is more interesting than the absolute value here: the absolute value from video underestimates by a few per cent, the difference does not.
- 4
Trunk lean, split up
Leaning from the ankles is not the same as folding at the hip, and by eye the two look alike. The report separates them, and that changes the cue you give.
Keeping measurements comparable
- Same speed. Cadence and stride length depend on it so strongly that a pace difference swamps everything
- Same shoes. A thicker midsole shifts the measured foot strike angle systematically
- Same camera position: square on, hip height, still, on a tripod
- Same point in the training week. After a hard long run people run differently
- At least twenty seconds, so there are enough stride cycles to average over
Where your role stops
A coach may give a technique cue. What a coach may not do, and what this software also does not do: is interpret a complaint. An athlete in pain belongs with a physiotherapist or a sports physician, and a measurement does not change that. This gives you numbers, not grounds to say anything about an injury.
The report holds that line: it contains the measurement and its quality, and no statement whatsoever about what this runner’s values mean. There is a reference library describing what the literature reports about each measure; it sits apart from the measurement and contains none of your athlete’s values.
Frequently asked
- Can I use this at the track?
- Yes, provided the camera stays on a tripod and square to the direction of travel. A panning or following camera does not work: the background moves and the scaling stops holding.
- How many athletes can I cover?
- Unlimited on the € 129 monthly subscription. If you do a handful a month, a bundle is cheaper; the pricing page works out where the crossover sits.
- Do I need a clinical background?
- Not to measure. To interpret a complaint, yes, and this tool is not built for that either. The measures themselves, cadence and contact time and overstride, are ordinary training measures.
- Does my athlete get something too?
- The report is a PDF you can forward. It includes an explanatory section stating what each measure is, written to go through together.

- Running gait analysis in sport and exercise medicine
What 2D video can and cannot measure, with the uncertainty stated. For anyone deciding whether a gait measurement will carry what gets built on it.
- For podiatrists: what video gait analysis does not measure
Honest answer: foot and ankle are the weakest part on 2D video. What this adds is what happens above the foot, and what changes when the orthosis goes in.
- For running stores: not the gait analysis you already do
This does not tell you which shoe fits. It does show what measurably changes in the running pattern between two shoes: which is a service you can sell on its own.
- Pricing for running gait analysis
Unlimited for € 129 a month, or from € 20 an analysis on a bundle. Bundles do not expire. First analysis free.
- Evidence: how it measures and what has been tested
Which model sits underneath, how gait events are established, what has and has not been validated, and why this is not a medical device.
- Recording protocol for running gait analysis
Camera position, frame rate, clothing and duration. The recording determines the measurement more than the software does, and this is what has to be right.
- Compared: camera, IMU sensors, a motion lab or the naked eye
What camera-based analysis can and cannot do against IMU sensors, a gait lab and assessment by eye. Including the places where the others win.
- Try it: the first analysis is free
One complete analysis with the report, no watermark and no card details. You need a twenty-second slow-motion clip and nothing else.

What pronation is, why sorting runners into neutral, over- and underpronating says less than long assumed, and what you can usefully look at instead.
