NHS Couch to 5K: How the 9-Week Running Plan Works

The NHS Couch to 5K plan takes you from no running to 30 minutes non-stop in nine weeks. You do three runs a week with a rest day between each one, and every session starts and ends with a 5-minute walk. Weeks 1 to 4 mix short runs with walking, weeks 5 and 6 build to 20 and 25 minutes, and weeks 7 to 9 are continuous runs.

Sportium, the NHS and the free Couch to 5K app

Couch to 5K is an NHS programme, and Sportium has no connection with it. The official plan, and the free NHS Couch to 5K app that talks you through each session, are on the NHS Couch to 5K page. The app gives you a new schedule each week, a choice of coaches and works alongside your own music. If anything in this guide differs from what the NHS publishes, follow the NHS version. What we add here is the plan set out on one page, the reasoning behind the rest days, and practical advice on kit and running safely through a British winter.

The 9-week plan, run by run

This table follows the NHS week-by-week running plan. Every session begins with a 5-minute warm-up walk and ends with a 5-minute cool-down walk, which are not included in the intervals below. In weeks 1 to 4 and 7 to 9 all three runs are the same; in weeks 5 and 6 each run is different.

Two points stand out. Weeks 2 and 3 have the same total running time, but week 3 asks you to hold a 3-minute run, so it often feels harder than the numbers suggest. The third run of week 5 is the biggest jump in the whole plan: you go from 8-minute efforts to 20 minutes without a walk. Plenty of people repeat week 5 or week 6 before moving on, and the plan allows that.

The finishing goal is 30 minutes of steady running rather than exactly 5km. At a relaxed jog many people cover somewhere between 3km and 5km in that time. Distance comes later if you want it.

Rest days between runs

The NHS plan says you should aim to have a rest day between each run. It repeats the reminder in later weeks, because that is when people feel good and are tempted to run on consecutive days.

Why a rest day between runs

Running loads your legs differently from walking. Muscles adapt fairly quickly, but tendons, joints and bones take longer to get used to the impact. The day off between sessions is when your body recovers from one run and gets ready for the next. If you run on consecutive days, you start each run already tired, and the niggles that make beginners give up are more likely to start.

Choosing your three days

Any pattern works as long as no two runs fall on back-to-back days. Put the days in your diary at the start of each week, rather than waiting to see how you feel.

What to do on rest days

• Keep moving gently. A walk, an easy bike ride or a gentle swim keeps you active without repeating the impact of running. Keep it easy enough that your legs feel fresh for the next run.
• Stretch or do some mobility work. Ten minutes of gentle calf, hamstring, quad and hip stretches is plenty. A foam roller from our Recovery & Supports range is useful if your calves feel tight.
• Add a little strength work, if you like. Squats, lunges, calf raises and a plank help your legs cope with running. Keep it short and avoid heavy leg sessions the day before a run.
• Sort your kit. Charge your phone and lights, dry your shoes and plan your route for the next session.

Sleep and normal meals matter more than any recovery gadget. You do not need special drinks or supplements for a 30-minute run.

When to repeat a week

The NHS plan says that if you need to repeat any of the runs or weeks, that is okay. Repeat the week if:

• you had to stop and walk during most of the running intervals;
• the last run of the week left you struggling to breathe, rather than tired but comfortable;
• you missed one or more runs that week;
• you have been ill or something has been aching for more than a day or two.

Repeating a week means doing all three runs again, with rest days in between. Never make up for a missed run by running two days in a row or doubling up a session.

What to do if you miss runs

1. Missed one run: do it on your next free day, then keep a rest day before the following run.
2. Missed a week or so: go back to the last week you completed comfortably.
3. Away for several weeks or ill: drop back a few weeks and rebuild. If you have been unwell, make sure you have recovered first, and check with a GP before restarting if you had anything more than a mild cold.

Who the plan suits

The NHS plan is aimed at people who have not run before, or not for a long time, and it works just as well for people coming back after injury or a break. Three half-hour sessions a week also go a long way towards the 150 minutes of moderate activity in the UK physical activity guidelines. If you have a heart or lung condition, joint problems, are pregnant or are worried about your health, the NHS advises talking to a GP before you start. Treat this page as general guidance; your own GP knows your health history.

Kit you need

Running shoes

Shoes are the only thing worth spending time on. Choose a pair that feels comfortable from the first step, with about a thumb's width of room in front of your longest toe and a heel that does not slip. For most Couch to 5K routes, which are mostly pavement and park paths, a cushioned road shoe works well. If your route is mostly muddy fields and towpaths, a trail shoe with more grip is worth it. Our running shoes buying guide explains fit, cushioning and road versus trail shoes.

Clothing

• Sports bra: a supportive, well-fitting one makes running much more comfortable.
• Socks: synthetic or merino running socks rather than cotton, which holds sweat and causes blisters.
• Layers: a light, sweat-wicking top and a thin windproof or showerproof layer. You warm up quickly, so dress for a temperature about 10°C warmer than it is outside.
• Phone holder: the app needs your phone, so a running belt or armband from running belts and bags keeps it secure.

Lights and visibility for winter

Between October and March most evening runs happen in the dark. The NHS advises making sure you can see where you are going, that other road users can see you, and picking well-lit routes. Rule 3 of the Highway Code rules for pedestrians says to wear something light-coloured, bright or fluorescent in poor daylight. When it is dark, use reflective materials, which drivers can see in their headlights up to three times as far away as non-reflective materials.

• A head torch lights uneven pavements, kerbs and park paths, and makes you visible to oncoming cyclists. A beam you can angle down avoids dazzling people. See head torches.
• Reflective and hi-vis kit: a vest, armbands or ankle bands. Ankle bands move with every stride, which makes them stand out in headlights. See hi-vis and reflective gear.
• A small clip-on rear light on your waistband or belt helps on roads without pavements.

Where there is no pavement, Highway Code rule 2 says to walk on the right-hand side of the road, facing oncoming traffic, and the same applies when you are running. You can browse shoes, layers and accessories in our running department.

Staying safe and motivated

• Go at chatting pace. In the early weeks you should be able to say a short sentence while you run. If you cannot, slow down rather than walk.
• Do the warm-up and cool-down walks every time. They are part of the plan.
• Keep your headphone volume low enough to hear traffic, bikes and people around you.
• Stop if something feels wrong. Pain that gets worse as you run, swelling, or pain that changes how you move means you should stop and get advice from a GP or physiotherapist.
• Run with someone. Running with a friend is more sociable and helps on dark evenings.

Your Couch to 5K checklist

• Get the free NHS Couch to 5K app from the NHS website and choose three run days with a rest day between each.
• Speak to a GP first if you have health concerns.
• Walk for 5 minutes before and after every run.
• Follow the table: intervals in weeks 1 to 4, building runs in weeks 5 and 6, continuous runs in weeks 7 to 9.
• Repeat any week that felt too hard. Never run on back-to-back days to catch up.
• Wear comfortable, supportive running shoes, and use a head torch and reflective kit on winter evenings.

Frequently asked questions

Do I need a rest day between Couch to 5K runs?

Yes. The NHS plan says you should aim to have a rest day between each run. The day off lets your legs recover, so run on alternate days, for example Monday, Wednesday and Saturday.

What can I do on Couch to 5K rest days?

Light activity is fine: a walk, an easy bike ride, a gentle swim or some stretching. Keep it easy enough that your legs feel fresh, and do not swap in an extra run.

Can I repeat a week of Couch to 5K?

Yes. The NHS plan says it is okay to repeat any of the runs or weeks. Repeat all three runs of the week if you struggled, missed sessions or have been unwell.

What happens in week 5 of Couch to 5K?

Each run in week 5 is different: 5-minute runs with 3-minute walks, then two 8-minute runs with a 5-minute walk between them, then 20 minutes of running without a walk. Many people repeat this week.

Is this the official NHS Couch to 5K app?

No. Sportium is not connected with the NHS. This guide summarises the published NHS plan; the official plan and the free app are on the NHS website.

Do I have to run 5km at the end of the plan?

No. The plan builds up to 30 minutes of continuous running. How far that takes you depends on your pace, and many beginners cover between 3km and 5km.
