Week 8 is three sessions, each one: run 28 min without stopping. That adds up to 84 minutes of running for the week, and the longest stretch without a walk break is 28 minutes.

What week 8 asks of you
Week 8 adds 3 minutes to the continuous run, from 25 to 28 minutes. All three sessions are identical, and each lasts 38 minutes including the warm-up and cool-down walks. It is a small increase, 12 percent, but those last 3 minutes are new ground every time until they are not. At a 13:00 mile, 28 minutes of running covers about 2.15 miles; at 11:00, about 2.55. When Week 8 feels hard, fitness is often not the issue. Boredom and clock-watching are. Breaking the run into mental chunks helps more than speeding up to get it done.
Day 1: run 28 min without stopping
28 minutes for the first time. Session 22 of 27 · 28 min running · 38 min door to door.
Today's run is 28 minutes, 3 more than Week 7. The session is 38 minutes, with the run from minute 5 to minute 33. The first 25 minutes are known ground. The new part starts at minute 30 on the clock, when you pass 25 minutes of running. Those last 3 minutes can feel longer than they are, mostly because you know they're extra. The middle of the run, around minutes 12 to 20, may feel easier than it did in Week 7.
Compared with the session before (week 7 day 3), running time goes from 25 to 28 minutes and the longest unbroken run from 25 to 28 minutes.
Keep the Week 7 pace. If anything, start 15 seconds per mile slower and stay there. At 13:00 per mile, 28 minutes of running covers about 2.15 miles; with the walks, the session totals about 2.71. At 11:00, about 5.5 mph, the session totals about 3.1 miles, but only about 2.55 of those miles are running. Talk test at minute 20 and minute 25 of the run.
If 28 minutes breaks, do 25 continuous, walk 1, then run 3. That is the Week 7 run plus the new part. Next time, try it straight through. If you stopped before minute 25 of the run, slow by 30 to 60 seconds per mile and repeat Day 1. Going back to Week 7 is rarely needed.
After this session you will have run 343 of the plan's 489 total minutes.
Day 2: run 28 min without stopping
Holding 28 minutes. Session 23 of 27 · 28 min running · 38 min door to door.
Second time through the 28-minute run, same 38-minute session. With the new length done once, today is about making it routine. Expect the last 3 minutes, minutes 30 to 33 on the clock, to feel shorter than on Day 1. The middle can drag, especially around minute 15 of the run, when you are past the halfway point but the end is far off. Compared with Week 7, you are running 3 more minutes, about 0.23 miles more at a 13:00 mile.
Compared with the session before (week 8 day 1), running time goes from 28 to 28 minutes and the longest unbroken run from 28 to 28 minutes.
Split the 28 minutes into four 7-minute blocks. Run the first block slightly slower than the rest, and hold the same effort through blocks two to four. At 13:00 per mile, each 7-minute block is about 0.54 miles. On a treadmill at 4.6 mph, leave the speed alone for the whole run. If talking in sentences gets hard during block three, drop to 4.4 mph.
If boredom or fatigue stops you, try a different fallback than on Day 1: run 14, walk 1, run 14. It keeps all 28 running minutes and gives one break at halfway. If you have used a fallback on both Days 1 and 2, repeat Day 1 before Day 3. You can also stretch to two rest days before the next run.
After this session you will have run 371 of the plan's 489 total minutes.
Day 3: run 28 min without stopping
The last run before 30. Session 24 of 27 · 28 min running · 38 min door to door.
Third 28-minute run, and the last session before Week 9 asks for the full 30. The workout is identical to Days 1 and 2: 38 minutes with the run from minute 5 to minute 33. Today the question is not whether you can run 28 minutes but how it feels at the end. If minutes 30 to 33 on the clock feel like you could keep going for 2 more, Week 9 is ready. You are now just 2 minutes short of the goal.
Compared with the session before (week 8 day 2), running time goes from 28 to 28 minutes and the longest unbroken run from 28 to 28 minutes.
Run the first 10 minutes at your easiest steady pace, then hold. If you have been running 13:00 miles, about 4.6 mph, keep it. At 15:00 per mile, the session covers about 2.42 miles; at 13:00, about 2.71; at 11:00, about 3.1 including warm-up and cool-down walks. At the end of the run, try one sentence out loud. If you can, the pace is right for Week 9.
If you could not run 28 minutes today but managed it earlier in the week, repeat Day 3 once more, then move to Week 9. If none of the three runs went the full 28, repeat Week 8. For a fallback today, run until you need to stop, walk 1 minute, then run the remaining minutes at a slower pace.
After this session you will have run 399 of the plan's 489 total minutes.
How far 28 minutes goes, by pace
| Run pace | Treadmill | Distance in 28 min | Whole session with walks | Short of 5K by |
|---|---|---|---|---|
| 10:00 / mile | 6.0 mph | 2.80 mi (4.51 km) | 3.36 mi | 0.49 km |
| 11:00 / mile | 5.5 mph | 2.55 mi (4.10 km) | 3.10 mi | 0.90 km |
| 12:00 / mile | 5.0 mph | 2.33 mi (3.76 km) | 2.89 mi | 1.24 km |
| 13:00 / mile | 4.6 mph | 2.15 mi (3.47 km) | 2.71 mi | 1.53 km |
| 14:00 / mile | 4.3 mph | 2.00 mi (3.22 km) | 2.56 mi | 1.78 km |
| 15:00 / mile | 4.0 mph | 1.87 mi (3.00 km) | 2.42 mi | 2.00 km |
| 16:00 / mile | 3.8 mph | 1.75 mi (2.82 km) | 2.31 mi | 2.18 km |
All three sessions this week are the same single run, so the useful number is distance rather than a minute-by-minute timeline. The run is 28 minutes whatever your pace; the table shows what that covers. Only paces quicker than 9:01 per mile reach 5K inside this run.
Repeat it or move on?
Repeat Week 8 if you walked during two or more of the three runs, or if minutes 25 to 28 felt like a sprint to the finish rather than more of the same. You're ready for Week 9 when 28 minutes feels like a long version of 25, not a different effort.

Frequently asked questions
Will I be able to run 5K by the end of Week 8?
Probably not continuously, and that is expected. A 5K is about 3.1 miles. Running 28 minutes covers that only at a pace near 9:00 per mile. At 13:00 per mile, a 5K takes about 40 minutes. The plan targets 30 minutes of running first; the full distance can come afterward.
What if I am slower now than in Week 5?
That is common and fine. Longer runs at an even effort tend to come out slower per mile than shorter ones. The plan measures time, not pace, so a slower 28 minutes counts the same as a faster one. Use the talk test to check effort, not the pace readout.
Why does Week 8 add only 3 minutes?
Because the plan is close to its goal. From 25 to 28 is a 12 percent increase, and from 28 to 30 in Week 9 is about 7 percent. Small steps at this stage keep the runs steady instead of turning the last weeks into a scramble. Week 4 had the big jump; the end is gentler.
Is it normal to feel worse in Week 8 Day 2 than Day 1?
Yes. Day 1 has the excitement of a new length. Day 2 has the same length without the novelty, and possibly some leftover tiredness. If you finished the 28 minutes, the session did its job. If you did not, a slower start on Day 3 usually helps more than extra rest.
How much harder is Week 9 than Week 8?
Two minutes more running: 30 instead of 28, about a 7 percent increase. Sessions grow from 38 to 40 minutes. It is one of the smallest increases in the plan. If 28 minutes felt steady, 30 is usually not a problem, though it can feel big in the head because it is the goal.
