Couch to 5K: the complete guide
Couch to 5K is a free, nine-week NHS running plan that alternates running and walking, three sessions a week, until you can run for 30 minutes without stopping. NHS describes that finish line as 30 minutes of continuous running, and also says you'll be running 5K by the end; for a slower runner, 30 minutes of running can add up to less than 5K. The full week-by-week structure, verified against NHS's own plan, is below.
"Couch to 5K" gets searched two ways: people who want to know if the plan works, and people already on it who want to see the whole thing at once instead of unlocking it week by week in an app. Every row in the table below is checked directly against NHS's published plan.
The nine-week plan, week by week
Each of the three weekly sessions includes a 5-minute warm-up walk and a 5-minute cool-down walk; the totals below include those. NHS recommends a rest day between each of the three runs in a week.
| Week | Run/walk pattern | Total time per session |
|---|---|---|
| 1 | Run 1 minute, walk 1 minute 30 seconds, repeated 7 times, then a final 1-minute run (8 runs in total) | 28 min 30 sec |
| 2 | Run 1 minute 30 seconds, walk 2 minutes, repeated 5 times, then a final 1-minute 30-second run | 29 min |
| 3 | 1:30 run, 1:30 walk, 3-minute run, 3-minute walk, 1:30 run, 1:30 walk, then a final 3-minute run | 25 min |
| 4 | 3-minute run, 1:30 walk, 5-minute run, 2:30 walk, 3-minute run, 1:30 walk, then a final 5-minute run | 31 min 30 sec |
| 5 | Three different sessions this week: 5-min run/3-min walk repeated to a final 5-min run; 8-min run/5-min walk/8-min run; and a first unbroken 20-minute run | 30 to 31 min |
| 6 | Three different sessions this week: 5-8-5 minute running blocks split by 3-minute walks; two 10-minute runs split by a 3-minute walk; and an unbroken 25-minute run | 33 to 35 min |
| 7 | 25 minutes running, no walk breaks, all three sessions | 35 min |
| 8 | 28 minutes running, no walk breaks, all three sessions | 38 min |
| 9 | 30 minutes running, no walk breaks, all three sessions | 40 min |

What the programme promises, and what it doesn't
NHS's own description of the outcome appears two ways on its Couch to 5K landing page, which sits one level above the week-by-week plan: "by the end you'll be running for 30 minutes without stopping," and separately, "by the end, you'll be running 5K with confidence, no matter your starting fitness level or when you last exercised." The two aren't identical: 30 minutes of running covers different distances at different paces, so a slower runner might not yet cover the full 5K in that time even after finishing week 9. If the actual distance question matters more to you than the weekly structure, how far you should be able to run covers that separately.
NHS is also explicit that the 9-week timeline is flexible: the plan can run "9 weeks or longer, depending on what works best for you," and "there's no pressure to keep up with anyone else." Both lines come from that same landing page rather than the week-by-week plan page the table above is drawn from.
Why the structure works this way
The pattern across all nine weeks is the same shape: running time grows and walk breaks shrink, until by week 7 the walk breaks are gone entirely. Week 4 still has three walk breaks inside a 31-minute session, and week 5's first unbroken run is only 20 minutes, well short of week 9's 30: the change happens gradually, over several weeks.
NHS builds a rest day into the schedule: "you should aim to have a rest day between each run," on the same page as the plan itself. And on kit, the advice is minimal by design: "wear whatever feels comfortable to move in, along with running shoes that support your feet, and a supportive bra if you need one." Nothing in the official plan requires specialist gear to start week 1.
Common mistakes on the plan
- Skipping ahead because a week felt easy. The progression is gradual on purpose; jumping from week 3 to week 6 removes the buildup that makes week 9 possible.
- Not repeating a week that's too hard. NHS's own advice is that repeating is "totally okay," so skipping the repeat out of impatience works against the plan's own design.
- Skipping the rest day. Running all three weekly sessions back to back removes the recovery NHS builds into the schedule.
- Chasing a kilometer number instead of the minutes on the schedule. The plan is time-based for a reason; checking a watch for distance mid-week 4 measures the wrong thing.
What to do after week 9
Once you're running 30 minutes continuously, the couch-to-5K structure has done its job, and a program built for holding or extending that fitness takes over. Runked's 5K training plan picks up from week 9's finish line with structured pace and volume targets. If you want to know what a solid 5K time actually looks like once you're running it regularly, what's a good 5K time covers that with age and sex breakdowns from a race-results dataset. And if week 1 is still ahead of you rather than behind, how to start running when you're unfit covers the run-walk basics this page assumes.
The useful comparison from here on is your own last few weeks, not another runner's pace or mileage. Runked's rank starts everyone at Bronze regardless of experience, and only moves on your own runs.

Does Couch to 5K actually get you to 5K?
NHS describes the outcome two ways: "by the end you'll be running for 30 minutes without stopping," and also "by the end, you'll be running 5K with confidence, no matter your starting fitness level or when you last exercised." The two can differ in practice: 30 minutes of running covers different distances at different paces, so a slower runner might still be short of 5K after finishing week 9. See how far you should be able to run for more on why distance varies by training age rather than by week number alone.
Can I repeat a week?
Yes, and it's built into the plan rather than a workaround. NHS's own guidance on the Couch to 5K running plan is direct: "Focus on taking it step by step, and if you need to repeat any of the runs or weeks, that's totally okay." There's no penalty for taking longer than 9 weeks: NHS itself says the plan can run "9 weeks or longer, depending on what works best for you."
What if I miss a week?
NHS doesn't publish specific guidance for a missed week, so treat it the same way as the repeat-a-week rule above rather than skipping ahead on the calendar: go back to the last week that felt solid and run it again before moving forward. A single missed session is smaller than that; since NHS already builds a rest day between each of the three weekly runs, one extra day off is unlikely to set you back much. A missed week is different from a missed day: repeat the week before moving on.
Which app should I use?
The free NHS Couch to 5K app is the right tool while you're actually on the plan: it times the run-walk intervals and talks you through each session, at no cost, on iOS or Android. Runked is built for what comes after: once you're running continuously, it turns each run into progress toward a rank instead of raw mileage, and weekly leagues scored on effort rather than pace, so a beginner's session counts fairly next to a faster runner's. PRO adds a 5K training plan and race-time predictions once week 9 is behind you.
