Week 5 is three sessions: run 5 min, walk 3 min, run 5 min, walk 3 min, run 5 min; then run 8 min, walk 5 min, run 8 min; then run 20 min without stopping. That adds up to 51 minutes of running for the week, and the longest stretch without a walk break is 20 minutes.

What week 5 asks of you
Week 5 is the only week where all three sessions differ. Day 1 is three 5-minute runs with 3-minute walks, 15 minutes of running in total. Day 2 is two 8-minute runs around a 5-minute walk, 16 minutes of running. Day 3 is one 20-minute run with no walking at all. Compared with Week 4, total running per session stays about the same until Day 3, but the longest run goes from 5 minutes to 8 and then to 20. Many people feel fine on Day 1, uneasy on Day 2, and nervous before Day 3. The 20-minute run is mostly a pacing test, and the usual reason it falls apart is a start that was too fast.
The jump from week 4
| Week 4 | Week 5 | Change | |
|---|---|---|---|
| Running minutes, whole week | 48 | 51 | +3 |
| Longest run without a walk break (min) | 5 | 20 | ×4.0 |
| Walk-break minutes, whole week | 16.5 | 11 | |
| Door-to-door minutes per session | 31.5 | 31 / 30 |
Week 5 is one of the steep steps of the plan: running time for the week goes from 48 to 51 minutes and the longest single run from 5 to 20. Session length barely moves, so the extra running comes out of the walk breaks. If any week earns a repeat, it is one with numbers like these.
Day 1: run 5 min, walk 3 min, run 5 min, walk 3 min, run 5 min
Three 5-minute runs. Session 13 of 27 · 15 min running · 31 min door to door.
Today you run 5 minutes three times, with 3-minute walks between. Total running is 15 minutes, actually 1 minute less than Week 4, and the walks are longer, so this session can feel like a small relief. Total time is 31 minutes. The runs sit at minutes 5 to 10, 13 to 18, and 21 to 26. The third one is the hardest, but with a full 3-minute walk before it, it rarely feels like Week 4's final run. Enjoy it. Day 2 is a bigger step.
Compared with the session before (week 4 day 3), running time goes from 16 to 15 minutes and the longest unbroken run from 5 to 5 minutes.
| # | Segment | Length | Starts at | Ends at |
|---|---|---|---|---|
| 1 | Warm-up walk | 5:00 | 0:00 | 5:00 |
| 2 | Run | 5:00 | 5:00 | 10:00 |
| 3 | Walk | 3:00 | 10:00 | 13:00 |
| 4 | Run | 5:00 | 13:00 | 18:00 |
| 5 | Walk | 3:00 | 18:00 | 21:00 |
| 6 | Run | 5:00 | 21:00 | 26:00 |
| 7 | Cool-down walk | 5:00 | 26:00 | 31:00 |
Clock times from the moment you start the warm-up walk.
Keep the pace you settled on in Week 4, or even go a touch slower. The aim this week is building toward 20 minutes, so practice a pace you could stretch. At 13:00 per mile, the session covers about 2.04 miles; at 15:00, about 1.89. On a treadmill, 4.0 to 4.6 mph for runs and 3.3 for walks is a sensible range. The talk test still applies in every minute of running.
| Run pace | Treadmill | Running distance | Whole session |
|---|---|---|---|
| 15:00 / mile | 4.0 mph | 1.00 mi | 1.89 mi (3.04 km) |
| 13:00 / mile | 4.6 mph | 1.15 mi | 2.04 mi (3.29 km) |
| 11:00 / mile | 5.5 mph | 1.36 mi | 2.25 mi (3.63 km) |
This is one of the gentler sessions in the second half of the plan, so trouble here is a useful signal. If the third run breaks, check your pace: you may be running faster than in Week 4 because the walks feel longer. Slow by 30 seconds per mile and repeat Day 1 before trying the 8-minute runs on Day 2.
After this session you will have run 141 of the plan's 489 total minutes.
Day 2: run 8 min, walk 5 min, run 8 min
Two 8-minute runs. Session 14 of 27 · 16 min running · 31 min door to door.
Two longer runs today: 8 minutes, a 5-minute walk, then 8 minutes again. Total running is 16 minutes in a 31-minute session. The longest run jumps from 5 minutes to 8, and there are only two runs instead of three. The first run, minutes 5 to 13, tends to go well until around minute 10, when you pass the 5-minute mark you know. The second run, starting at minute 18, gets heavy in its last 3 minutes. That stretch is the preview of Day 3.
Compared with the session before (week 5 day 1), running time goes from 15 to 16 minutes and the longest unbroken run from 5 to 8 minutes.
| # | Segment | Length | Starts at | Ends at |
|---|---|---|---|---|
| 1 | Warm-up walk | 5:00 | 0:00 | 5:00 |
| 2 | Run | 8:00 | 5:00 | 13:00 |
| 3 | Walk | 5:00 | 13:00 | 18:00 |
| 4 | Run | 8:00 | 18:00 | 26:00 |
| 5 | Cool-down walk | 5:00 | 26:00 | 31:00 |
Clock times from the moment you start the warm-up walk.
This is the session where pace starts to matter more than effort. Run the first 8 minutes slower than feels natural. If you are on a treadmill and usually run 4.6 mph, try 4.4. At 13:00 per mile, 8 minutes covers about 0.62 miles, so the two runs add up to about 1.23. With walks, the session totals about 2.06 miles. If you can talk at minute 7, the pace is right.
| Run pace | Treadmill | Running distance | Whole session |
|---|---|---|---|
| 15:00 / mile | 4.0 mph | 1.07 mi | 1.90 mi (3.06 km) |
| 13:00 / mile | 4.6 mph | 1.23 mi | 2.06 mi (3.32 km) |
| 11:00 / mile | 5.5 mph | 1.45 mi | 2.29 mi (3.68 km) |
If you cannot finish the second 8-minute run, split it: run 5, walk 1, run 3. Do not shorten the 5-minute walk in the middle to make up time. If you split both runs, repeat Day 2 after a rest day before trying the 20 minutes. If you completed both runs but finished exhausted, that is still a success; move to Day 3.
After this session you will have run 157 of the plan's 489 total minutes.
Day 3: run 20 min without stopping
20 minutes without stopping. Session 15 of 27 · 20 min running · 30 min door to door.
This is the session people talk about. After two days with walk breaks, you run 20 minutes straight, from minute 5 to minute 25, with no walking. Your longest run goes from 8 minutes to 20. Total running is 20 minutes, 4 more than Day 2, and the session takes 30 minutes. The early minutes often feel fine. The hard stretch tends to arrive between minutes 8 and 14 of the run, just past anything you have done before. The last 5 minutes often feel easier than the middle.
Compared with the session before (week 5 day 2), running time goes from 16 to 20 minutes and the longest unbroken run from 8 to 20 minutes.
| # | Segment | Length | Starts at | Ends at |
|---|---|---|---|---|
| 1 | Warm-up walk | 5:00 | 0:00 | 5:00 |
| 2 | Run | 20:00 | 5:00 | 25:00 |
| 3 | Cool-down walk | 5:00 | 25:00 | 30:00 |
Clock times from the moment you start the warm-up walk.
Go slower than any run so far. If you ran Day 2 at 13:00 per mile, try 14:00 to 15:00 today, about 4.3 to 4.0 mph on a treadmill. Twenty minutes at 15:00 per mile is about 1.33 miles of running; at 13:00, about 1.54. With the walks, the session covers about 1.89 to 2.09 miles. Use the talk test every 5 minutes. If sentences get hard, slow down instead of stopping.
| Run pace | Treadmill | Running distance | Whole session |
|---|---|---|---|
| 15:00 / mile | 4.0 mph | 1.33 mi | 1.89 mi (3.04 km) |
| 13:00 / mile | 4.6 mph | 1.54 mi | 2.09 mi (3.37 km) |
| 11:00 / mile | 5.5 mph | 1.82 mi | 2.37 mi (3.82 km) |
If 20 minutes is not happening, split it: run 10, walk 1, run 10. That keeps almost all the running and gives you one checkpoint. Next time, try the full 20 again at a slower pace. If even the split did not work, repeat Day 2 once and return. If something feels wrong, stop and walk; if something hurts rather than feels tired, stop for the day.
After this session you will have run 177 of the plan's 489 total minutes.
Repeat it or move on?
Repeat the relevant day rather than the whole week. If Day 2 needed walk breaks inside either 8-minute run, do it again before attempting Day 3. If Day 3 broke into pieces, try it again after a rest day at a slower pace. You're ready for Week 6 once 20 minutes runs continuously, even slowly.
If a session goes badly, the stuck-week helper gives a specific next step for week 5.
Frequently asked questions
Can I skip Day 2 and go straight to the 20-minute run?
You can, but Day 2 is the bridge. The 8-minute runs show you what a pace that lasts feels like before you need it for 20 minutes. Going from 5 minutes straight to 20 is a fourfold jump in the longest run. With Day 2 in between, the steps are 5 to 8 to 20.
How slow is too slow for the 20-minute run?
There is no lower limit that matters. If your running pace is close to your walking pace, that still counts as running continuously. At 15:00 per mile you cover about 1.33 miles in the 20 minutes; at 13:00, about 1.54. Distance is not the goal of this session. Not stopping is.
Why does Week 5 Day 1 feel easier than Week 4?
It has slightly less running, 15 minutes instead of 16, and the walks between runs are 3 minutes instead of 90 seconds to 2.5. The longest run is still 5 minutes. It is a breather before the 8-minute runs on Day 2 and the 20-minute run on Day 3.
Is the 5-minute walk in Week 5 Day 2 long enough?
It is the longest walk break in the plan, which is deliberate. Use the first 2 minutes to let your breathing settle and the last minute to walk a bit faster so you are ready to start. If you feel fully settled after 3 minutes, still walk all 5. The second run needs it.
Why is Week 5 Day 3 such a big step?
The longest run goes from 8 minutes to 20 in two sessions, two and a half times longer. The usual reason it breaks is speed, not fitness. If you finished both 8-minute runs on Day 2, the time is likely within reach; the common problem is starting the first 5 minutes too fast. Start slower than feels useful.
