If you have started a 9-week run/walk plan more than once and stopped somewhere in the middle, you are not starting from zero. You are starting from a known week. The useful question is not “why did I quit” but “which week do I go back to, and what do I change this time.”
This guide gives you both: a restart table built from this site’s restart rule, and the practical changes that make attempt two, three or five different from the last one.
Which week should I restart from?
Go back further the longer you were off. After one week off, repeat the week you were on. After two, three or four weeks off, go back one, two or three weeks. After five or six weeks off, restart at half your old week, rounded up. After seven or more weeks off, start at week 1, or week 2 if you had reached week 7 or later.
The same rule powers the restart calculator. Here is every combination:
| Week you reached | 1 wk off | 2 wks off | 3 wks off | 4 wks off | 5–6 wks off | 7+ wks off |
|---|---|---|---|---|---|---|
| Week 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| Week 2 | 2 | 1 | 1 | 1 | 1 | 1 |
| Week 3 | 3 | 2 | 1 | 1 | 2 | 1 |
| Week 4 | 4 | 3 | 2 | 1 | 2 | 1 |
| Week 5 | 5 | 4 | 3 | 2 | 3 | 1 |
| Week 6 | 6 | 5 | 4 | 3 | 3 | 1 |
| Week 7 | 7 | 6 | 5 | 4 | 4 | 2 |
| Week 8 | 8 | 7 | 6 | 5 | 4 | 2 |
| Week 9 | 9 | 8 | 7 | 6 | 5 | 2 |
“Week you reached” means the last week you completed all three days of. If you stopped partway through week 5, count week 4.
For worked examples with the exact sessions, see restarting after 2 weeks off, after 4 weeks off and after 8 weeks off.
Why is the rule this cautious?
Because the plan’s jumps are uneven. Run time per session goes 8, 9, 9 minutes in weeks 1 to 3, then 16 minutes in week 4, then up to a 20-minute continuous run at the end of week 5. Restarting one week too far forward often lands you right before one of those jumps with less fitness than you had the first time.
Going back an extra week costs three sessions of roughly 30 minutes each. Restarting too far forward and stalling again costs far more. The table is built to accept the first cost to avoid the second.
What should I change on attempt two, three or four?
Change how you run, not just when you start. Three changes do most of the work: run slower, fix your days in advance, and decide before week 1 that repeating weeks is allowed. Each one removes a common reason people stall.
Run slower than feels necessary. The CDC’s talk test describes moderate effort as being able to talk but not sing, and vigorous effort as not being able to say more than a few words without pausing for breath (CDC). On a restart, aim for the first one. On the pace pages, dropping from 12:00 to 14:00 min/mile cuts the week 9 run from 2.5 to 2.14 miles. That is a small distance cost for a much more manageable effort. There is more on this in how easy should easy running feel.
Fix three days before you start. The NHS plan uses three runs a week with rest days between them (NHS). Pick three non-consecutive days, such as Monday, Wednesday and Saturday, and keep them for all nine weeks. The plan builder turns your days into a calendar file so the sessions appear on their own.
Allow repeats in advance. The NHS says the plan can take 9 weeks or longer. Decide now that you will repeat any week where a session felt like a struggle. A plan with two repeated weeks takes 11 weeks and still finishes at 30 minutes of running. The stuck week helper and repeat a week or move on cover when a repeat makes sense.
What does a restart week look like in practice?
Say you reached week 6 and then took three weeks off. The table sends you to week 4: run 3 min, walk 90 sec, run 5 min, walk 2.5 min, run 3 min, walk 90 sec, run 5 min. That is 16 minutes of running inside a session of about 31.5 minutes including the 5-minute warm-up and cool-down walks. See week 4, day 1 for the full breakdown.
If all three week 4 days feel comfortable, move to week 5 as normal. If day 3 of week 5, the 20-minute run, is where you stopped before, plan to do week 5 twice before trying it.
How do I keep this attempt on track?
Keep a simple record of each session: the date, the week and day, and one word for how it felt. When you see two “hard” entries in a row, repeat the week instead of pushing on. Print the 9-week plan and tick off each day; seeing the finished boxes makes it easier to restart from the right place if life gets in the way again.
If you have a health condition or haven’t exercised in a long time, check with a doctor before starting.
Restarting a 9-week run/walk plan after a break
- Find your restart week. Look up the last week you finished and how many weeks you were off in the restart table, and begin at the week it shows.
- Slow your running pace. Run slowly enough that you can talk in full sentences. Speed is not the goal on a restart.
- Fix three days. Pick three non-consecutive days and put them in your calendar for the whole plan before your first run.
- Allow repeats. Plan to repeat any week that felt like a struggle. A 9-week plan that takes 11 weeks still ends at 30 minutes of running.
