The walk test: five kilometres in an hour

The walk test: 5 km on foot in 60 minutes or less, at a brisk pace. Brisk is about 3 miles an hour, and you can still talk but not sing (NHS, checked 29 August 2026). It is the distance a stopped train or a closed road can hand you.

What the walk test is

The second of the five Ready Body tests, and the one most people pass first time without knowing it. Five kilometres is about 3.1 miles. An hour is the standard.

How to do it.

1. Pick a real route, not a treadmill. Pavements, kerbs, a road crossing or two. Out and back is easiest to measure, and it means you finish at your own door.
2. Measure it once. A phone map, a fitness watch or a known route such as a local parkrun course. Getting the distance right matters more than the timing device.
3. Wear ordinary shoes. The NHS puts it plainly: any shoes or trainers that are comfortable, provide adequate support and do not cause blisters will do. If your honest answer is work shoes, test in work shoes at least once.
4. Walk briskly from the start. The NHS test for brisk is that you can still talk but cannot sing the words to a song. That is the pace, whatever the watch says.
5. Time it door to door, including the crossings and the hill. Real routes have both.

Do it on a normal day, not after a night shift, and not in the hottest hour of a hot afternoon.

The pass standard

Five kilometres in 60 minutes or under, and you feel you could carry on if you had to. That second half matters. Arriving inside the hour and needing to sit down for twenty minutes is a different result from arriving inside the hour and being able to unpack the shopping.

Sixty minutes for 5 km works out at 5 km/h, which is about 3.1 miles an hour. The NHS describes a brisk walk as about 3 miles an hour, faster than a stroll, so the pass standard is simply brisk walking held for an hour.

What it maps to in a real emergency

Getting home. Trains stop, roads close, a car will not start, a bus route is cut. Five kilometres is the sort of distance that separates most people from their workplace, their child’s school or the nearest shop that still has power. It is a walk, not a drama, if your body treats an hour on its feet as ordinary.

It also maps to everything else a disrupted day involves: standing in a queue for a water bowser, walking to a relative to check on them, being on your feet in a hall or a rest centre. GOV.UK Prepare suggests making a plan to check in on neighbours when an emergency happens, particularly if the power goes out. Checking on people is a walking job.

And it is the backbone of the NHS guidelines. Brisk walking is the NHS’s headline example of moderate intensity activity, and 150 minutes a week of moderate activity is the adult target. Three 50-minute brisk walks meet it on their own, whatever else you do or do not do.

The four-week progression

The same plan as on the tests page. Build minutes before pace: the hour is the hard part, not the speed.

From week 3, put a small backpack on with a bottle of water in it, so walking with a load feels normal.

Week 5 is the retest: 5 km, timed, on the route you measured.

If four walks a week is not realistic, three will still get you most of the way, and the walks can be commutes, school runs and errands rather than separate outings. The NHS points out that even a brisk 10-minute daily walk counts towards the weekly total.

How to make it easier

• Split it. Two walks of 2.5 km in the same day is a fair way to start. The distance is the target; doing it unbroken can wait.
• Flatten the route. Hills cost minutes and knees. Save them for later.
• Give yourself 75 minutes, then 70, then 65. Timing yourself down in five-minute steps is more motivating than failing the hour four times.
• Walk with someone. The talk test looks after itself when you have someone to talk to.
• Change the shoes before you change the plan. Blisters end more walks than fitness does.

How to make it harder

• Add a load. Five kilometres with a 5 kg backpack, then 8 kg. That is closer to walking home with what you were carrying anyway.
• Add distance. Eight kilometres, then 10, at the same pace. Being able to walk 10 km at need is a quietly useful thing.
• Test in bad weather. A wet, windy November walk in a proper coat tells you more than a June one.
• Do it in the shoes you actually commute in, and find out now rather than then.
• Walk your real route home. From the office, from the station, from the school. Once. It stops being an abstraction and becomes a route you know, which is the point of the whole test.

Knowing that route also makes your go bag more useful, because you can pack for the walk you have actually done.

Is it safe?

Speak to your GP first if you have not exercised for some time, or if you have medical conditions or concerns. That is the NHS’s line and it applies to the test as much as the training.

• Build up gradually. The NHS advice for anyone not very active is to increase walking distance gradually rather than in one jump.
• Take water, particularly in warm weather, and walk in the cooler part of the day when it is hot.
• Be visible after dark. Reflective or light-coloured clothing, and a torch on unlit stretches.
• Stop for chest pain or tightness, dizziness or feeling faint. The NHS says to call 999 if “you get sudden pain or discomfort in your chest that does not go away”, if “you get pain that spreads to your left or right arm, or your neck, jaw, stomach or back”, or if “you have chest pain and you feel sweaty, sick, light headed or short of breath” (NHS, checked 30 August 2026). If you are unsure what a symptom means, call NHS 111.
• Look after your feet. Blisters are the most common reason a real walk home becomes a real problem. Shoes that fit, socks that do not bunch.

If joints make walking difficult, the NHS suggests alternatives such as swimming as a way of getting the same weekly minutes. Adapt the test rather than skip the fitness.

The 5 km and 60-minute standard is Prep Not Panic’s own, not a clinically validated test. It is set at the pace the NHS calls brisk, held for the sort of hour a bad day tends to ask for.

Frequently asked questions

How far is 5 km in miles?

About 3.1 miles. An hour for that distance is roughly a 19-minute mile, or 5 km/h, which matches the NHS description of a brisk walk as about 3 miles an hour.

Is walking 5 km in an hour good?

It is a solid ordinary standard rather than an athletic one: brisk pace, sustained for an hour. Plenty of people beat it comfortably. If you are well inside the hour and could keep going, treat the test as passed and add a backpack.

Does this count towards the 150 minutes a week?

Yes. Brisk walking is the NHS’s main example of moderate intensity activity, and the adult guideline is at least 150 minutes of it a week. Three walks of this length cover the whole guideline.

What if I use a stick, a frame or a wheelchair?

Adapt the distance and the time, and keep the principle: can you cover the ground between you and home, in one go, with whatever you normally use. The NHS’s fitness advice for wheelchair users asks for “at least 150 minutes a week of aerobic activity, plus strength exercises on 2 or more days a week”, the same weekly targets as everyone else, and adds: “Do not worry about hitting these targets straight away: it’s more important to do something active that you enjoy” (checked 30 August 2026).

Do steps on a fitness tracker count?

They are a decent proxy for movement but not for this test, which is about distance, pace and how you feel at the end. Measure the route once and time it, then use steps day to day if you find them motivating.

Should I run it instead?

Only if you already run. The test is about walking because walking is what you will actually do while carrying something, wearing the wrong shoes, or keeping pace with a child or an older relative.

What if 20 minutes is my limit today?

Then week 1 of the plan is exactly right, and the NHS view is that any activity is better than none. Four 20-minute walks a week is a real start, and most people move up a week at a time without much drama.
