Couch to 5K: the complete plan, week by week

Updated 1 October 2026

Couch to 5K is a simple idea: you don't start by running, you start by running a little and walking a lot. Over eight weeks the running parts get longer and the walking parts shorter, until you run 5K — or 30 minutes — without stopping. Three sessions a week, about 30 minutes each.

It works because it respects the part of you that adapts slowest. Your heart and lungs improve within weeks. Tendons, bones and joints take longer, and most beginners who get hurt do so because they let their breathing set the pace and their legs couldn't keep up.

The full 8-week schedule

This is the plan the Lufa app runs for a complete beginner — three sessions a week:

  1. Week 1

    • 1. 8 × run 1:00 / walk 1:30
    • 2. 8 × run 1:00 / walk 1:30
    • 3. 8 × run 1:00 / walk 1:30

  2. Week 2

    • 1. 6 × run 1:30 / walk 2:00
    • 2. 6 × run 1:30 / walk 2:00
    • 3. 6 × run 1:30 / walk 2:00

  3. Week 3

    • 1. 5 × run 2:00 / walk 2:00
    • 2. 5 × run 2:00 / walk 2:00
    • 3. 5 × run 2:00 / walk 2:00

  4. Week 4

    • 1. 4 × run 3:00 / walk 2:00
    • 2. 4 × run 3:00 / walk 2:00
    • 3. 4 × run 3:00 / walk 2:00

  5. Week 5

    • 1. 3 × run 5:00 / walk 2:30
    • 2. 2 × run 8:00 / walk 3:00
    • 3. run 10:00 · walk 3:00 · run 8:00

  6. Week 6

    • 1. 2 × run 10:00 / walk 3:00
    • 2. run 12:00 · walk 3:00 · run 8:00
    • 3. run 20:00

  7. Week 7

    • 1. run 22:00
    • 2. run 25:00
    • 3. run 25:00

  8. Week 8

    • 1. run 28:00
    • 2. run 28:00
    • 3. 5 km without stopping

Every session starts with a 5-minute brisk walk and ends with a 5-minute walk.

Run slowly. Slow enough to talk in short sentences. Nearly every beginner runs too fast in week 1, and the plan only works at a pace you could keep going at.

What each week feels like

Week 1 — one minute of running, eight times. It sounds easy until minute six. The goal here is not fitness; it's getting out of the door three times.

Week 2 — 90 seconds. The first week where some people are sore the day after. That's normal; sharp pain is not.

Week 3 — two minutes. Most people find this week easier than they feared. Your breathing starts to settle in the second half of each run.

Week 4 — three minutes. The first real jump. If you finish the runs but feel wrecked, slow down rather than repeat.

Week 5 — the big one. Five-minute runs, then eight, then ten minutes with a short break. The third session is where many people expect to fail and don't. Your body can do more than your head thinks by now.

Week 6 — twenty minutes. The week ends with your first continuous 20-minute run. Pace doesn't matter at all. Finishing does.

Week 7 — 22 to 25 minutes. Now it's about patience, not effort. The runs feel long, not hard.

Week 8 — the finish. Two 28-minute runs, then the graduation run: 5 km without stopping. For most beginners that takes 30 to 45 minutes — the 5K time calculator will tell you roughly where you'll land.

When a week is too hard

Repeat it. This is the most important rule of Couch to 5K and the one people most often ignore. If you couldn't complete the running parts, or you felt awful afterwards, do the week again. Repeating a week costs seven days. Pushing through and getting shin splints costs a month.

Other good fixes:

  • Slow down. A slower run you finish beats a faster one you abandon.
  • Lengthen the walk. Taking 30 extra seconds of walking before a hard interval is a smarter move than stopping halfway through it.
  • Leave a full day between sessions. Running on consecutive days is where most beginner aches come from.

How long does Couch to 5K really take?

Eight weeks is the standard. In practice many people take nine to twelve, because they repeat a week, get ill, or go on holiday — and that's fine. If you can already run for a few minutes, you may need fewer. The when can I run a 5K calculator estimates your own date.

Do you have to run exactly 5K at the end?

The original plan ends with 30 minutes of running, which for many beginners is less than 5 km. Lufa's graduation run ends at the actual distance — 5 km, measured by GPS — because that's what most people mean when they say "I want to run a 5K". If you have no GPS signal, a 35-minute run counts instead.

Couch to 5K with an app

You can follow the table above with a stopwatch. Most people find an app easier, because it tells you out loud when to run and when to walk, so you're not staring at your phone. The Lufa app also adapts the plan: after every run you say how it felt, and it repeats or eases a week when it needs to — the step most people skip when they follow a fixed plan on paper.
