Couch to 5K: a coach's 9-week plan from zero to your first 5K

The short answer

Couch to 5K takes you from no running at all to 30 minutes non-stop — roughly 5K — in nine weeks, with three run-walk sessions a week. That is the NHS structure, and it works. What a coach adds is what turns nine weeks into a habit that lasts: the right pace, the right rest, the strength work that keeps you injury-free, and a plan for the day after you finish.

Who wrote this plan

I'm Bez, founder and head coach at Lift Republic: RQF-qualified in gym instructing, personal training and sports nutrition (Levels 2–4), and a runner with marathons and a 50 km ultramarathon behind me. This is how I coach beginners. One runner I coach started from nothing in December 2025 and finished a half marathon nine months later, starting from these same rules.

The 9-week plan, week by week

Every session starts with a 5-minute brisk walk and ends with a 5-minute walk to cool down. Run three times a week with a rest day between each run.

The weeks follow the NHS Couch to 5K plan; the free NHS app cues the run and walk changes in your earphones if you'd rather not watch a clock.

My five rules for beginners

1. Easy means easy. Run at a pace you could hold a conversation at. The runners who stall are the ones who race every session; the easy runs are where the fitness is built.
2. One change at a time. Keep the same three days every week and let only the running minutes grow. A routine you don't have to think about is one you keep.
3. Rest days are training. Never run two days in a row in the first weeks. Your legs, tendons and bones adapt on the days off.
4. Repeat a week, never skip one. If a session felt too hard, run that week again. Nine weeks is a guide, not a deadline.
5. Keep it fun. Once you can run for 20 minutes, finish one run a week with four relaxed 20-second strides: quick, smooth, never a sprint. Sessions you enjoy are sessions you do.

The strength work Couch to 5K leaves out

Most new-runner niggles — sore shins, achy knees, tight calves — come from muscles and tendons that aren't yet strong enough for the pounding. Two short strength sessions a week fix that. On non-running days, or straight after an easy run, do 3 sets of 8–12 of:

• Squats (or sit-to-stands from a chair)
• Split squats, each leg
• Calf raises, slow on the way down
• Glute bridges
• A plank, 20–40 seconds

Twenty minutes, no gym needed. At Lift Republic every running plan includes strength work, because strong runners are the ones still running a year later.

Your first parkrun: the free 5K benchmark

parkrun is a free, timed 5K every Saturday morning in parks across the UK. Register once, bring your barcode and run at your own pace — plenty of people walk parts of it. Aim for your first parkrun in week 9 or straight after. That first time is your baseline: it is the number I use to set every training pace from then on.

After your first 5K: how to run faster

Finishing Couch to 5K is the start. To get faster:

• Set your paces from your 5K time, not by feel. Easy runs go about 60–90 seconds per km slower than your 5K pace, and tempo runs about 20–30 seconds per km slower. The running pace calculator below turns your 5K time into your pace per km and per mile and predicts your 10K and half-marathon times.
• Keep about 80% of your running easy. Speed comes from the other 20%, and it only works if the easy runs are properly easy.
• Add one quality session a week. For example 5 × 3 minutes at your 5K effort with 2 minutes' easy jogging between, or 20 minutes at a comfortably hard tempo.
• Keep your strides and your strength sessions. Both make you more economical, so the same pace costs you less.
• Grow your longest run slowly. Add a few minutes a week and hold it every third or fourth week.

Stick with it and expect faster times within 6–8 weeks. Re-run the calculator after each new best so your paces keep up with you.

Common problems, and the fix

• Shin pain: slow down, check your shoes aren't worn out, and add calf raises. Sharp or worsening pain means stop and see a physiotherapist or your GP.
• Can't finish a session: repeat the week. The plan is built to be repeated.
• Out of breath: you're running too fast. Slow down until you can talk; walking breaks are part of the plan, not a failure.
• Stitch: slow down and breathe out fully for a few steps.

If you have a heart or other health condition, or you get chest pain, dizziness or unusual breathlessness while running, stop and speak to your GP before you carry on.
