Week 1 of 9
Week 1 of the beginner 5K plan
Week 1 is three sessions, each one: 8 × (run 1 min, walk 90 sec). That adds up to 24 minutes of running for the week, and the longest stretch without a walk break is 1 minute.

What week 1 asks of you
Week 1 asks for 8 minutes of running in total, delivered as eight 1-minute runs, each followed by 90 seconds of walking. With the 5-minute warm-up and 5-minute cool-down walks, each session lasts 30 minutes. There is no previous week to compare with, so these numbers are your baseline: 8 run minutes, 12 walk minutes between runs, and a longest run of 1 minute. Walking still makes up 60 percent of the interval block. The people who find it hard are usually the ones who start too fast; a one-minute run at near-sprint effort leaves nothing for runs six, seven, and eight. Slow jogging, barely quicker than a brisk walk, is the right speed here.
Day 1: 8 × (run 1 min, walk 90 sec)
Eight 1-minute runs. Session 1 of 27 · 8 min running · 30 min door to door.
This is the first session, so there is nothing to compare it with. You walk 5 minutes, then alternate 1 minute of running with 90 seconds of walking, eight times, then walk 5 minutes more. The first run starts at minute 5 and the last one starts at minute 22:30. Runs one and two usually feel easy, which is the trap. By run six, around minute 17:30, your legs start to notice. Expect the 90-second walks to feel short in the second half. Total running today is 8 minutes out of 30.
This is the first session of the plan, so there is nothing to compare it with yet — the only job today is to finish feeling you could have done a little more.

Clock times from the moment you start the warm-up walk.
Run slowly enough that you could say a full sentence without gasping. For a lot of beginners that is barely faster than a brisk walk. At a 15:00 mile you cover about 1.76 miles in the whole session, walks included; at 13:00, about 1.84. On a treadmill, try 3.3 mph for the walks and 4.0 to 4.6 mph for the runs. These are starting points. Adjust by feel, not by the number on the screen.
| Run pace | Treadmill | Running distance | Whole session |
|---|---|---|---|
| 15:00 / mile | 4.0 mph | 0.53 mi | 1.76 mi (2.83 km) |
| 13:00 / mile | 4.6 mph | 0.62 mi | 1.84 mi (2.96 km) |
| 11:00 / mile | 5.5 mph | 0.73 mi | 1.95 mi (3.14 km) |
If a run falls apart before the minute is up, walk until the next run starts and keep the rest of the schedule. Try the next run at half the speed. If you cannot finish runs seven and eight, walk them and count the session as done. If something feels off, stop and walk; if something hurts rather than feels tired, stop for the day. Repeat this session next time before moving on.
After this session you will have run 8 of the plan's 489 total minutes.
Day 2: 8 × (run 1 min, walk 90 sec)
The same eight runs, second round. Session 2 of 27 · 8 min running · 30 min door to door.
Same structure as Day 1: eight 1-minute runs, 90-second walks, 30 minutes start to finish. The numbers do not change, but you might. Legs that felt fresh on Day 1 can feel heavier now, especially during the warm-up walk. That usually fades by the second or third run. The tougher stretch tends to come earlier than on Day 1, around runs four and five, between minutes 12:30 and 16. If Day 1 went well, aim to make all eight runs feel the same rather than faster.
Compared with the session before (week 1 day 1), running time goes from 8 to 8 minutes and the longest unbroken run from 1 to 1 minutes.
Use Day 1 as your reference. If you ran 13:00 miles then and gasped by run eight, try 14:00 today, about 4.3 mph on a treadmill. If Day 1 felt calm, keep the same speed. Covering 1.84 miles in the session at a 13:00 mile is plenty. Check yourself in the final seconds of run five: can you still say a sentence? If not, slow the last three runs.
Heavy legs from Day 1 are the usual problem today. If the first two runs feel bad, stretch the warm-up walk to 8 minutes and then begin. If you have to cut runs short, cut each one to 45 seconds rather than skipping runs entirely, so you keep the rhythm of eight. Leave at least one full day off before Day 3.
After this session you will have run 16 of the plan's 489 total minutes.
Day 3: 8 × (run 1 min, walk 90 sec)
Last round of 1-minute runs. Session 3 of 27 · 8 min running · 30 min door to door.
Third time through the eight 1-minute runs, and the last before the runs get longer. By now the routine should feel familiar: 5 minutes of walking, the 20-minute interval block, 5 minutes of cool-down. Today is a checkpoint more than a challenge. Watch how run eight, which starts at 22:30, compares to run one. If they feel similar, you can move up. Next week each run grows by 30 seconds to 90, and the walks grow to 2 minutes.
Compared with the session before (week 1 day 2), running time goes from 8 to 8 minutes and the longest unbroken run from 1 to 1 minutes.
Try to hit the same pace in every run, and note what it was. That number is your starting point for Week 2. If you ran close to 13:00 per mile, the session totals around 1.84 miles; nearer 11:00, about 1.95. The 8 running minutes alone at a 13:00 mile come to roughly 0.62 miles. Keep the talk test as your guide, even if you feel like pushing on the last day.
If today goes worse than Day 1 or 2, do not move up. Repeat Day 3 after a rest day. If only the last two runs were a struggle, you can still try Week 2 Day 1, since its walks are longer. If three or more runs fell apart, repeat the whole of Week 1 at a slower speed, around 15:00 per mile or 4.0 mph.
After this session you will have run 24 of the plan's 489 total minutes.
Repeat it or move on?
Repeat the week if you had to cut runs short in two or more sessions, or if the 90-second walks never felt long enough to settle your breathing. You're ready for Week 2 when the last of the eight runs feels about as manageable as the first and you could say a full sentence during it.
If a session goes badly, the stuck-week helper gives a specific next step for week 1.
Frequently asked questions
Is Week 1 too easy if I already walk a lot?
It might feel easy, and that is fine. Walking fitness helps, but running asks something different of your legs, and the plan builds that up slowly on purpose. If all three sessions feel comfortable, move on to Week 2 on schedule rather than skipping ahead. The jumps get bigger later, and a calm Week 1 makes Week 4 easier.
Do I need to run on three specific days?
No. Any three days work as long as there is a day without running between sessions, for example Monday, Wednesday, and Friday, or Tuesday, Thursday, and Saturday. The day off gives your legs time to adjust. If life gets in the way, shift the session by a day rather than doubling up.
How fast should I run on my very first day?
Slower than you think. A good test is whether you could talk in full sentences while running. If you can only manage a few words, ease off. First-timers often run the opening interval far too fast because one minute sounds short. A pace near 15:00 per mile, about 4.0 mph on a treadmill, is a reasonable place to start.
My legs still feel heavy from Day 1. Is it okay to run anyway?
Mild heaviness is normal after a first session and usually eases during the warm-up walk. Start the session and see how the first two runs feel. If the heaviness gets worse instead of better, walk the rest and try again another day. The plan works on any schedule that keeps a day off between running sessions.
Can I skip ahead to Week 3 if Week 1 felt easy?
It is better not to. Week 1 being easy is the design, not a sign the plan is too slow. Week 2 adds 30 seconds to each run, and Week 3 doubles the longest run to 3 minutes. Those steps are small on paper but add up. Skipping now makes Week 4, the biggest jump, much harder.
