- You need to be able to run 5K comfortably first. Then build the Sunday long run by about 1 km a week.
- Run three or four days a week, keep Wednesday and Saturday-style rest days, and keep most runs easy.
- Stop and get medical advice for chest pain, dizziness, or pain that gets worse as you run.
If you can already run 5K without stopping, eight weeks is a realistic time to prepare for a first 10K. The idea is simple: keep most runs short and easy, and grow one longer run each week.
Before you start
This plan is for you if you can run 5K comfortably (if not, begin with our 5K plan). The structure follows the published 8-week beginner 10K plan from Nuffield Health: three or four runs a week, one strength session, and two full rest days. That plan, like the NHS, advises a check-up with a doctor before you start, especially if you have a heart or circulation condition or any other health concern.
Pick a race or a Sunday at least eight weeks away. A date on the calendar makes the plan easier to keep.
The 8-week table
Distances come from the Nuffield Health plan; the layout is simplified. Easy runs are at a conversational pace. Strength can be bodyweight work at home: squats, lunges, calf raises and planks.
| Week | Easy run (Mon) | Quality run (Thu) | Recovery (Fri) | Long run (Sun) |
|---|---|---|---|---|
| 1 | 15 min | 10 x 30 sec faster, 1 min easy | 15 min easy or rest | 5 km |
| 2 | 20 min | 10 x 30 sec hill sprints | 20 min easy | 6 km |
| 3 | 25 min | 10 x 60 sec faster, 90 sec easy | 25 min easy or rest | 7 km |
| 4 | 30 min | 10 x 30 sec hill sprints | 30 min easy or rest | 8 km |
| 5 | 35 min | Rest | 35 min easy or rest | 9 km |
| 6 | 20 min | 10 x 30 sec hill sprints | 20 min easy or rest | 6 km |
| 7 | 25 min | 10 x 60 sec faster, 90 sec easy | 25 min easy or rest | 7 km |
| 8 | 20 min | Rest | 20 min easy or rest | 10 km race |
Tuesday is the strength day, and Wednesday and Saturday are full rest days. If hill sprints are hard to find, do the faster efforts on flat ground, or skip them and run easy.
Why weeks 6 and 7 go down
After the longest run in week 5, the distance drops. This lets your legs recover and absorb the training, so you arrive at race day fresh rather than tired. It is not a step backwards.
How to pace each run
- Easy and recovery runs: comfortable pace. If you are going too fast, slow down; the aim is to complete the distance, not to be quick.
- Long runs: a pace you can hold the whole way. Starting too fast is the most common reason a long run goes wrong.
- Race day: about 70 to 80 percent of your maximum effort, where you could still hold a light conversation. Settle in during the first km or two, then speed up in the last part if you feel good.
A heart-rate watch helps, but it is optional. The talk test works just as well.
How a typical week feels
Take week 3 as an example. On Monday you jog 25 minutes at an easy pace and finish feeling you could have gone further. Tuesday is strength work at home. Wednesday you rest. On Thursday you do ten one-minute efforts a little faster than easy pace, with 90 seconds of easy jogging between them. On Friday you jog an easy 25 minutes or rest. Saturday is a rest day. On Sunday you run 7 km, slowly. The week adds up to a few hours of activity, which is well above the 150 minutes of moderate activity a week that the World Health Organization recommends for adults, but most of it is easy running.
If a week feels too hard, repeat it before you move on. If it feels too easy, resist the urge to add extra runs; the long run and the rest days are doing the work.
Rest, sleep and food
Treat rest days as part of the plan. If you miss a run, the Nuffield plan advises treating it as an extra rest day and rejoining at the next scheduled run, rather than doubling up. In Indian summers, run early and carry water; see running in Indian heat and monsoon. Keep your shoes in good shape too: our shoe guide explains when to replace them.
When to stop and see a doctor
- Stop if you feel chest pain, severe breathlessness, fainting or dizziness, and get medical help.
- Take a few days off if pain in a joint, shin or foot gets worse while running, and see a doctor or physiotherapist if it does not settle.
- If it is very hot and you feel headache, nausea, or clammy skin, stop and cool down. The NHS describes confusion or hot, dry skin as signs of heatstroke, which is an emergency.

Race-week checklist
- Keep the easy runs short and do not try anything new, from shoes to breakfast.
- Check the start time, the route and where you will leave your bag.
- Sleep well in the last two nights. One bad night before the race matters less than a week of tired legs.
- Start at the back or middle of the crowd, and let faster runners go.
- If you are unwell on the day, skip the race. There will be another one.
Where next
After your 10K, you could look at the 12-week half marathon plan. Running with others also makes training easier: see how to join a run club. Treqz Run is coming soon, and nothing in this plan needs it.

Quick questions
Can I go from 5K to 10K in 8 weeks?
Many beginners can if they already run 5K comfortably. A published 8-week beginner plan from Nuffield Health builds the weekly long run from 5 km to 9 km, then lets you rest before the 10K.
Do I need to run 10K before race day?
Not necessarily. The plan below peaks at 9 km, and race-day excitement and a calm pace usually carry you the rest of the way. If you feel unsure, run 10 km easy once, two weeks before.
How many rest days do I need?
Plan at least two full rest days a week. Rest is when your body adapts to training.
What if I miss a week?
Repeat the last week you completed, then carry on. Do not try to make up the distance by doing double runs.
