Average walking speed

About 5 km/h, or 3.1 mph. That is the figure most often quoted, and it holds up well for a healthy adult walking on level ground with somewhere to be.

The honest answer is a range. Comfortable walking sits between 4.5 and 5.5 km/h for most adults, and the number moves with age, height, terrain, load and whether you are strolling or trying to get somewhere.

By purpose

Above roughly 8 km/h, walking becomes less efficient than running and most people spontaneously break into a jog. Race walkers train specifically to defeat that instinct, which is why their technique looks so unusual.

By age

Walking speed declines gradually through adulthood and then more sharply after about 65. Typical comfortable speeds:

Treat these as indicative. Individual variation within any age band is far wider than the difference between bands — a fit 70-year-old routinely outpaces a sedentary 30-year-old.

What changes your speed

Height and leg length. Taller people cover more ground per step at the same cadence. This is the single largest physical factor, and it is why the same "average" feels brisk to one person and slow to another.

Gradient. Uphill costs far more than downhill returns. A 5% incline typically reduces speed by around 20%, while a 5% descent adds only a few percent — and steep descents actually slow you down again as you brake.

Surface. Pavement is fastest. Grass, sand, gravel and snow each take a progressive bite out of your pace; soft dry sand can halve it.

Load. Carrying weight slows you roughly in proportion to the fraction of body weight carried. A heavy rucksack is worth a noticeable drop.

Company. People walking in pairs or groups go measurably slower than people walking alone, because pace converges on the slowest member and conversation takes effort.

Cities. Walking speed correlates with city size and pace of life. Pedestrians in large, dense, fast-moving cities genuinely walk faster than those in small towns — a finding replicated across many countries.

Why walking speed is a health measure

Gait speed is used clinically as a general indicator of function in older adults, sometimes called the "sixth vital sign". It is easy to measure and reflects the combined state of the heart, lungs, muscles, joints, balance and nervous system at once.

Slower usual walking speed in older adults is associated with poorer health outcomes, and a meaningful decline over time is treated as worth investigating. Roughly 0.8 m/s (2.9 km/h) is a commonly cited threshold below which independent community mobility becomes difficult.

This is a population-level association, not a personal diagnosis. If you are concerned about a change in how you walk, that is a question for a doctor, not for a speedometer.

How many steps per kilometre?

At an average stride, roughly 1,250 to 1,550 steps per kilometre, or about 2,000 to 2,500 per mile. Taller people take fewer.

The familiar 10,000-steps target works out to somewhere between 6.5 and 8 km, depending on your stride — around 75 to 90 minutes of comfortable walking.

Worth knowing: 10,000 steps has no particular scientific basis. It originated as a 1960s Japanese pedometer marketing figure, chosen partly because the character for 10,000 resembles a walking person. Research since suggests meaningful health benefits accrue well below that, and continue to rise with more.

Measuring your own

GPS struggles at walking pace more than at any other speed — the signal you are trying to detect is close to the receiver's noise floor, which is why a stationary phone sometimes reports 2 km/h.

For a reliable figure, walk a known distance and time it, or use Self Speed over a longer stretch where the random errors average out. Watch the accuracy reading: anything worse than about 10 m and the instantaneous number is not telling you much. See is GPS speed accurate.
