What the numbers mean

Pace. A brisk walk is about 1.4 metres a second: 12 minutes a kilometre, 19 a mile. Running starts near 2.2. Below that, going faster barely changes what a kilometre costs you. Above it the cost per metre roughly doubles, which is why a short run and a long walk can burn the same. The calorie figure uses the ACSM walking and running equations, which is what a treadmill uses.

Steps. Nearly 50,000 people across 15 studies on four continents. Against the least active quartile, averaging 3,500 steps a day, the three more active groups had 40 to 53 percent lower death rates. The benefit flattened around 6,000 to 8,000 steps for people over 60 and 8,000 to 10,000 under 60. Paluch et al, Lancet Public Health, 2022.

The half nobody quotes: pace did not matter. Once total steps were counted, how fast they were walked added nothing to the mortality figure. So the pace readout above is for your own interest, not for your risk. And ten thousand was the name of a 1960s pedometer, never a finding. The evidence on steps.

Common questions

How many calories does walking burn?
Roughly 50 to 70 calories per kilometre for most adults walking at a normal pace, and it scales almost directly with body weight: a 90 kg person burns about a third more than a 65 kg person over the same distance. Pace matters less than people expect while you are still walking. It matters a great deal once you start running, which costs close to twice as much oxygen per metre.
How does this work out calories?
From the oxygen cost of moving at the speed you actually moved, using the standard walking and running equations, multiplied by your body weight. It is worked out segment by segment rather than once at the end, so a walk that turns into a run is counted as both. It is an estimate for a person of your weight, not a measurement of you, and any tracker that claims otherwise is overselling.
Does my location get uploaded?
No. The coordinates are read by the page in your browser and used there. The route on screen is drawn from them locally, which is why it is the shape of your route rather than a street map: showing a street map would mean sending your position to a map company. Nothing about where you walked reaches us or anyone else.
Why does it stop when my screen locks?
Phones suspend a web page when the screen goes off, which cuts the location signal. The page asks to keep the screen awake where the browser allows it. For a longer session, keep the phone unlocked and in a pocket screen-out, or use a dedicated app. This is honest about being a browser tool rather than a background one.
How accurate is the distance?
Good in the open, poor between tall buildings and under heavy tree cover, which is true of every GPS device including expensive watches. Readings less accurate than about 35 metres are discarded rather than counted, and so are jumps that would mean moving faster than 12 metres a second. That is why a phone sitting still does not slowly accumulate a walk it never took.
How much walking should I be doing?
The clearest benefit arrives well before ten thousand steps. Mortality curves start bending down around three to five thousand steps a day and keep improving to roughly seven to eight thousand, after which the gains flatten. Anything above where you are now is the honest target.
