Why an Indoor Couch to 5K?
You do not need a track or a smartwatch. You need hallway floor space equal to three long strides and the willingness to move every other day. This plan—the same rhythm trusted by running clinics world-wide—trades pavement pounding for brisk laps around your living room, balcony, or backyard. It is safe, joint-friendly, and perfect after 40 or when rain, dark, or babysitting keeps you inside.
How This Plan Works
We follow the NHS standard 9-week schedule of three run-walk sessions per week, trims it to eight weeks for convenience, and swaps outdoor miles for timed work blocks using a phone timer. Each session is never over 30 minutes including warm-up and cool-down.
- Week 1–2: mostly walking punctuated with short jogs
- Week 3–4: bigger running chunks
- Week 5–6: single longer intervals
- Week 7–8: continuous running that peaks at 5 kilometers or 30 straight minutes—whichever you reach first
The Only Kit You Need
- A kitchen timer or the free C25K app
- Flexible trainers. Running-specific shoes are ideal; cross-trainers work.
- A water bottle you can set at one end of your running area
No treadmill, no bands, no heart-rate strap.
The Indoor Running Surface
Carpet or Rug
Ideal: soft landing, minimal noise. Wear gripped socks if the weave is plush.
Laminate or Hardwood
Put down two yoga mats end-to-end for softer impact.
Outdoors
Flat concrete balcony tiles or a small lawn are perfect. Steer clear of loose gravel.
Pre-Run Physical Check
Consult a physician if you are over 45, pregnant, recovering from injury, or have chest pain, diabetes, or high blood pressure. The NHS heart-risk questionnaire found in NHS Physical Activity Guidelines is a quick screen anyone can run at home.
Week-by-Week Couch to 5K Calendar
Three days on, one day off, repeat. Choose non-consecutive workout days—e.g., Mon-Wed-Fri. Rest days are full rest; light stretching is allowed.
Week 1
Session: 5 min brisk walk warm-up, then alternate 60 s jog / 90 s walk × 8 rounds, finish with 5 min easy walk cool-down. Total time: 26 min.
Week 2
Same structure, but extend the run portion to 90 s and the walk portion remains 90 s.
Week 3
Week 4
A 5 min warm-up, then 3 min jog, 90 s walk, 5 min jog, 2.5 min walk, 3 min jog, 90 s walk, 5 min jog. Cool-down.
Week 5
Day 1: 5 min warm-up, 5 min jog, 3 min walk, 5 min jog, 3 min walk, 5 min jog, cool-down.
Day 2: 5 min warm-up, 8 min jog, 5 min walk, 8 min jog, cool-down.
Day 3: The first 20-minute nonstop jog.
Week 6
You alternate 5 min jog, 3 min walk, 8 min jog, 3 min walk, 5 min jog. End with 25-minute continuous run.
Week 7
Three steady 25-minute runs at a conversational pace.
Week 8
Every run is 30 minutes nonstop, and one of them is converted into a full 5K distance check. If you hit 3.1 mi / 5 km before 30 minutes ends, you graduate. If not, the next moderate jog will get you the rest of the way.
Mastering the Micro-Loop
Most living rooms give you six to ten steps before you must turn around. That is fine: treat it like a 10-meter track lap. Keep your stride short, feet under hips, elbows tucked in. Resist the urge to sprint; think “easy Sunday park” pace.
Indoor Warm-Up (90 Seconds)
- March in place 30 s
- Toe touches 15 s
- Lunging hip flexor stretch 15 s each leg
- Ankle circles 15 s each foot
Cool-Down Stretch (2 Minutes)
- Standing quad stretch 30 s per side
- Calf stretch against wall or chair 30 s per side
- Gentle forward fold for hamstrings 30 s
Common Beginner Mistakes and Quick Fixes
Shin Splints
Cause: tight calves, hard surface with worn shoes. Fix: ice 10 min, calf raises daily, swap shoes.
Tight Hip Flexors
Cause: desk day followed by short indoor strides. Fix: kneeling hip flexor stretch after every run.
Side Stitch
Cause: eating within 60 min of running, shallow breathing. Fix: 2:2 breathing pattern—inhale on two footfalls, exhale on two footfalls.
Nutrition to Support the Plan
Focus on balance before gimmicks. Hydrate first: 500 ml water on waking, 250 ml each hour. Meals should supply 1.2–1.4 g protein per kilogram body-weight and enough complex carbs to power your sessions—think overnight oats with berries or a banana and peanut butter 60–90 minutes pre-run.
Post-Run Snack
250 ml low-fat milk or soy milk plus a piece of fruit replenishes glycogen and begins muscle repair within 30 minutes, per American College of Sports Medicine guidelines.
How to Stay Motivated
- Social proof: Join the free NHS Couch to 5K Facebook group and post screen shots of your timer days.
- Micro-rewards: New playlist every completed week.
- Visual cue: Tick each workout off on a wall calendar hung next to your running area.
Safety Tips for a Small Space
- Clear shoes, toys, and unstable furniture from the path.
- Run socks on carpet, shoes on hardwood to prevent slipping.
- Keep a ceiling fan on or crack a window; indoor air can heat up fast.
- If dizziness hits, stop and sit with head between knees for 30 s before resuming.
What Success Looks Like
By the end of Week 8 you will:
- Run 5 km without stopping or walk breaks in under 35 minutes
- Average heart rate 10–15 bpm lower on warm-up jog than Week 1, indicating improved aerobic base
- Feel able to add hill or speed elements once you take it outdoors
Frequently Asked Questions
How do I measure 5 km indoors?
Use a simple step-length method. Count your steps during one lap, multiply by the number of laps to reach 6,500–7,000 steps (average adult stride 0.75 m). Alternatively, if you have a smart phone just track one outdoor 5K once you finish the plan.
Can I repeat a week?
Yes. The number one reason outdoor C25K groups see dropout is ignoring leg soreness. Repeat any week as many times as needed until you can finish all intervals in relative comfort.
Is this safe for people over 50?
Absolutely. A 2022 cohort study in British Journal of Sports Medicine showed similar cardiometabolic benefits in 50–65-year-old beginners on treadmill-based 5K plans. The same walking-jogging ratio is the safest short-interval pattern available.
I have plantar fasciitis—can I still do this?
Begin sessions barefoot on yoga mats to strengthen arch muscles. Ice your heels post-run and roll a frozen water bottle underfoot. If pain exceeds mild discomfort, see a physiotherapist before next session.

Final Take
Indoor running does not mean second-best. Hallway laps strip away every excuse—weather, travel, gear cost—and force focus on technique and pacing. Stick to the three-sessions-per-week cadence, respect rest days, and by Week 8 you will have crossed the mythical 5K finish line without ever leaving the house.
