Set up and time the walk
One person walks. A helper holds the phone and times it. Use the walking aid you normally use. If balance is uncertain, the helper walks just behind and to the side.
Mark the course
On a level, clear floor: 1 metre to get going, then 4 metres that are timed, then 1 metre to slow down. Tape or two objects mark the start and the 4-metre line.
Usual pace
Walk the way you normally walk, not fast, not slow. Start behind the run-up and keep going past the 4-metre line.
Helper taps
Tap Start at the first footfall past the start line. Tap Stop at the first footfall past the 4-metre line.
Twice
Rest, then walk it again. The faster of the two counts, as in the NIA physical performance battery.
Your walking-speed log
Each saved walk stays in this browser on healthgait.com. It is not sent anywhere, it is not on your other devices, and clearing this site's data erases it. Timed walks from the calculator on the HealthGait homepage appear here too.
No timed walks saved yet. Time a walk above and save it, then repeat every month or so. One test is a snapshot; the trend is the signal.
What this number is, and what it is not
It is
- Your usual walking speed over 4 metres, in metres per second, from a stopwatch a person pressed.
- A number that tracks health in large studies: across 34,485 adults 65 and older, each 0.1 m/s faster went with about 12% lower risk of death, with no single cutoff (Studenski, JAMA 2011).
- Worth watching over time: a change of about 0.05 m/s is a small meaningful change, and about 0.10 m/s is substantial (Perera, 2006).
- A reason to talk to a clinician if it is under 0.8 m/s (more than 5 seconds for 4 metres), which BC's frailty guidance flags for clinical review.
It is not
- A diagnosis, a fall prediction for one person, or a measure of fitness for a specific activity.
- Exact. Hand timing, the course, shoes, and the day all move it a little. Compare like with like: same course, same shoes, same helper.
- A replacement for a clinician's gait and balance exam, or for a medication and vision review.
- Sent to anyone. It stays in this browser unless you choose to carry it to another site.
