Training plans
10K training plan that adapts to your recovery
The 10K sits between speed and endurance: long enough that the aerobic base decides most of your time, short enough that threshold and VO2max work pay off quickly. A good plan builds both without tipping into too much intensity. Here are the numbers by level, the sessions that matter, an example week and how to set your paces. At the end: how Keho Coach adjusts the same rules when your sleep, HRV or training load call for it.
Short answer
Train for 8–12 weeks on 3–6 days a week, depending on your level, or about 16 weeks with walk-run if 10 km would be your first run of that length. Grow your weekly distance by no more than about 10 % at a time, with an easier week every fourth week. Build the long run to 10–18 km, keep about 80 % of your running easy, add one or two quality sessions (threshold, 10K-pace intervals, hills) and cut the last week to about 60 % of your usual volume.
How long to train, and how many days a week
- First 10K (you can’t yet run 30–40 minutes without stopping): about 16 weeks of walk-run, three days a week, until the run is continuous.
- Beginner (you run 30 minutes comfortably): 10–12 weeks, 3–4 running days.
- Intermediate (you have raced 5K or 10K and run 25–35 km a week): 8–12 weeks, 4–5 days.
- Advanced (years of consistent training, 45 km a week or more): 8–10 weeks, 5–6 days.
If you have a heart condition or another health problem, or haven’t exercised in a long time, see a doctor before you start.
Weekly distance and the long run by level
| Level | Peak week | Longest run |
|---|---|---|
| Beginner | 25–32 km (16–20 mi) | 10 km (6 mi) |
| Intermediate | 40–50 km (25–31 mi) | 14 km (8.5 mi) |
| Advanced | 55–70 km (34–43 mi) | 18 km (11 mi) |
Start from what you run now. Add no more than about 10 % a week, drop to about three quarters every fourth week so the work sinks in, hold the peak for a week or two, then taper. The long run grows by 1–2 km at a time and steps back in cutback weeks. A long run longer than the race gives you the reserve to hold pace over the last 3 km.
Quality sessions for the 10K
Beginners need one quality session a week, intermediate runners one in the base phase and two from the build on, advanced runners two. Keep an easy day between hard days.
- Threshold (tempo): 20–30 minutes at a comfortably hard pace you could hold for about an hour, or 3–4 × 8–10 minutes with 2-minute jogs (tempo intervals). The backbone of 10K training.
- 10K-pace intervals: 5–6 × 1 km at 10K pace, or 3–4 × 2 km for advanced runners, with 2 minutes of easy jogging between.
- VO2max intervals: 5–6 × 3 minutes at about 5K pace, jogging the same time back.
- Hills: 6–10 × 60–90 seconds uphill at a strong effort.
- Strides: 4–8 × 20 seconds quick and relaxed after an easy run.
Order them by phase: strides, hills, fartlek and progression runs in the base; 10K-pace intervals, tempo and tempo intervals in the build; short race-pace touches in the taper.
Example week in the build phase
One example week about five weeks before the race, not a full plan.
| Day | Beginner (4 days) | Intermediate (5 days) | Advanced (6 days) |
|---|---|---|---|
| Mon | Rest | Rest | Rest |
| Tue | Intervals: 4 × 1 km at 10K pace, 7 km (4.5 mi) | Intervals: 5 × 1 km at 10K pace, 9 km (5.5 mi) | Intervals: 3 × 2 km at 10K pace, 12 km (7.5 mi) |
| Wed | Rest | Easy 6 km (4 mi) | Easy 10 km (6 mi) |
| Thu | Easy 5 km (3 mi) + strides | Rest | Easy 8 km (5 mi) + strides |
| Fri | Rest | Tempo: 20 min at threshold, 8 km (5 mi) | Tempo intervals: 4 × 8 min, 11 km (7 mi) |
| Sat | Easy 4 km (2.5 mi) | Easy 5 km (3 mi) + strides | Easy 6 km (4 mi) |
| Sun | Long run 9 km (5.5 mi) | Long run 13 km (8 mi) | Long run 17 km (10.5 mi) |
| Total | 25 km (15.5 mi) | 41 km (25.5 mi) | 64 km (40 mi) |
How to set your paces
Set paces from what you can run today, ideally a race in the last six to eight weeks. Pete Riegel’s formula scales it: predicted time = known time × (new distance ÷ known distance)1.06. A 5K in 25:00 predicts about 52:00 for 10K. Try the race time predictor with your own result.
- Easy: conversational, typically 60–90 seconds per km slower than 10K pace.
- Threshold: what you could race for about an hour; for most runners a little slower than 10K pace.
- Intervals: your current 10K pace, or 5K pace for the VO2max reps.
Without a recent race, run easy days below roughly 75–80 % of a maximum heart rate you have actually seen, and threshold work around 85–90 %. The heart rate zone calculator turns your numbers into zones.
A sub-60 and a sub-50 10K
60 minutes means 6:00 per km (9:39 per mile); 50 minutes means 5:00 per km (8:03 per mile). By the same formula, a sub-60 10K goes with roughly a 28:45 5K, a sub-50 with about 24:00. If your 5K is close, 10 weeks of the build above is a realistic route.
Taper and race day
Cut the last week to about 60 % of your usual volume but keep some speed, for example 3 × 1 km at 10K pace four days out. On race day, warm up for 10–15 minutes with strides, run the first 2 km at or a few seconds slower than goal pace, settle in, and push from 7 km.
When to change the plan
- Poor sleep: after one bad night, move the hard session a day. After several, make the next quality session an easy run.
- HRV and resting heart rate: if HRV sits clearly below your usual range, or resting heart rate above it, for several days, run easy or rest. How to read your HRV.
- Training load: if your last week is far above your usual weeks, hold rather than add. Training load explained.
- Feeling unwell: with a fever, chest symptoms or aching muscles, don’t run. Come back with a few easy days.
- Missed runs: carry on from today. After a missed week, repeat the last full week.
How Keho Coach builds and adapts your plan
- Choose a 10K race and its date, or Start running for the 16-week First 10K walk-run plan. Pick your level (New to running to Elite), how many days a week you run (1–7), which weekdays and your long-run day.
- Keho sets your paces from a recent race or personal best in Apple Health, otherwise from its VO2max estimate, otherwise from heart rate alone. Easy runs follow heart rate, faster work follows pace.
- Every week follows the rules above: the peak and longest run for your level, a capped weekly increase, a lighter week at least every fourth week and a taper to about 60 %. Without a hill nearby, hill repeats become a fartlek.
- The next seven days of runs go to your Apple Watch, with heart-rate and pace alerts from your own zones. Completed runs are matched to the plan automatically.
Nothing changes on its own. Tell Keho you are not feeling 100 % and the week adjusts, then ramps back. When several low-readiness mornings come with HRV below your usual or resting heart rate above it, when training load climbs too fast, or when you have missed several sessions, Keho offers options that only ever reduce load, always including “Keep as planned”. You decide. A 10K plan is $3.99 on its own or part of Keho Coach ($24.99 a year). Week 1 is readable before you buy, and your health data stays on your iPhone.
Common questions
How many weeks do I need to train for a 10K?
8–12 weeks if you already run regularly, about 16 weeks with walk-run if you are starting out.
How far should my longest run be before a 10K?
About 10 km for beginners, 14 km for intermediate and 16–18 km for advanced runners, all at easy pace.
What comes after the 10K?
The half marathon training plan doubles the distance with the same rules and a longer long run.
