10K Training Plan
This 12-week 10K training plan has four runs a week: two easy runs, one quality session and a long run that builds from 8 km to 15 km (9.3 mi) in week 11. Every fourth week is a lighter cutback week, and race week doubles as the taper. The full dated plan below is a sample for a 50:00 goal and a race on Sunday 18 April 2027.
It suits a runner who can run 5K comfortably and wants structured speed work without marathon-sized long runs.

What pace should each run in the plan be?
The paces come from your VDOT, the fitness score a race time implies in Jack Daniels' tables. A 50:00 10K works out at a VDOT of 40.0, which puts easy running at 9:25-10:49 per mile (5:51-6:43 per km). Easy really does mean easy: most of the plan is run at that pace.
| Run type | Per mile | Per km |
|---|---|---|
| Easy and longMost of your running. Conversational, builds the aerobic base. | 9:25-10:49 | 5:51-6:43 |
| ThresholdComfortably hard, about one hour race effort. Raises the pace you can hold. | 8:12 | 5:05 |
| IntervalHard 3 to 5 minute reps. Builds VO2 max. | 7:33 | 4:41 |
| Goal race pace50:00 over 10k distance. | 8:03 | 5:00 |

How is this 10K training plan built?
The plan is counted back from race day, so week 12 ends on the race and week 1 starts 83 days earlier. It runs in three phases:
- Base, weeks 1-4. Easy running and strides only. The long run goes 8 to 9 km, and weeks total 23 to 24 km.
- Build, weeks 5-11. Quality sessions (threshold and intervals) join the easy running. The long run goes 10 to 15 km, and weeks total 30.5 to 38.5 km.
- Race week, week 12. A short sharpener midweek, easy shakeouts, then the race on Sunday 18 April 2027.
Cutback weeks. Every fourth week is lighter so the training can sink in: week 4 (long run 8 km after 9 km) and week 8 (long run 10 km after 12 km). The last build week, week 11, is never a cutback.
Taper. The taper is race week itself: 14 km of running before the race, against 38.5 km in week 11, the last build week. A meta-analysis of taper studies found the best results from a taper of 8 to 14 days that cut volume by 41 to 60% while keeping intensity, which is why the quality session stays in.

What does each run type in the plan mean?
Each run in the table carries a letter. 39 of the plan's 48 runs (81%) are easy runs, strides or long runs, which together cover 75% of its 364 km. Studies of endurance athletes find the same pattern: around 80% of training sessions are done at low intensity, with the hard work kept to the rest.
- E
Easy 24 runs · 9:25-10:49/mi · 5:51-6:43/km
Conversational running. It builds the aerobic base and lets you recover from the hard days.
First one: week 1, Easy 5 km. Conversational pace.
- S
Easy + strides 4 runs · 9:25-10:49/mi · 5:51-6:43/km
An easy run with a few short, relaxed accelerations at the end. Strides keep some leg speed during the base weeks without adding fatigue.
First one: week 1, Easy 5 km + strides. Easy run, then 6 × 20 s relaxed fast strides with a walk back.
- T
Threshold 5 runs · 8:12/mi · 5:05/km
Comfortably hard reps, about the effort you could hold for an hour in a race. They raise the pace you can sustain before fatigue builds quickly.
First one: week 5, 3 × 6 min threshold. 3 × 6 min at threshold pace, 1 min jog between.
- I
Intervals 3 runs · 7:33/mi · 4:41/km
Hard reps of about 3 to 5 minutes with equal jog recovery. They work on your VO2 max, the top of your aerobic range.
First one: week 6, 5 × 800 m intervals. 5 × 800 m at interval pace, equal-time jog between.
- L
Long run 11 runs · 9:25-10:49/mi · 5:51-6:43/km
The longest run of the week, at easy pace. It builds endurance and is the place to rehearse race-day fuel.
First one: week 1, Long run 8 km. Easy pace the whole way. Practise race-day fuel on the longer ones.
- R
Race 1 run
Race day. Start at goal pace, not faster, and let the pace band keep you honest.
First one: week 12, Race day: 10K. Start at goal pace, not faster. Use the pace band.

How do you adjust the plan for 3, 5 or 6 days a week?
The long run and the phases stay the same; what changes is how many easy runs and quality sessions sit around them. On three days the plan runs Tue, Thu and Sun and keeps one quality session, peaking at 32.5 km (20.2 mi) a week. On six days it runs Mon, Tue, Wed, Thu, Fri and Sun, with threshold and intervals in a peak week, and tops out at 58 km (36.0 mi). Add days only when the current number feels easy; the extra runs are easy running, not extra hard sessions.
| Days | Quality sessions | Peak week | Peak long run | Whole plan |
|---|---|---|---|---|
| 3 days | 1 a week: Threshold or Intervals | 32.5 km / 20.2 mi | 15 km / 9.3 mi | 299 km |
| 4 days | 1 a week: Threshold or Intervals | 38.5 km / 23.9 mi | 15 km / 9.3 mi | 364 km |
| 5 days | 2 a week: Threshold + Intervals | 52 km / 32.3 mi | 15 km / 9.3 mi | 466 km |
| 6 days | 2 a week: Threshold + Intervals | 58 km / 36.0 mi | 15 km / 9.3 mi | 531 km |
When should you start a 12-week 10K plan?
Count back from race day. The plan ends on the race, so day one is 12 weeks minus one day before it. For a race on Sunday 18 April 2027:
12 weeks × 7 days = 84 days, ending on race day
Sunday 18 April 2027 minus 83 days
Start on Monday 25 January 2027
The planner offers 8 and 12 weeks for a 10K and picks the longest that fits before your race. These are the start dates for the same race day:
| Plan length | Start | Taper |
|---|---|---|
| 8 weeks | Monday 22 February 2027 | 1 week |
| 12 weeks | Monday 25 January 2027 | 1 week |
The planner builds this same plan for your own goal time or a recent race result, counted back from your race date, with your training paces, race-day splits, a pace band and a calendar file.

How many weeks do you need to train for a 10K?
The planner builds 10K plans from 8 to 12 weeks and picks the longest one that fits before your race. This page shows the 12-week version. If you already run regularly, the shorter end works; if you are newer to running or coming back from a break, give yourself the full 12 weeks.
How long is the longest run in this 10K plan?
15 km (9.3 mi), in week 11, which is one week before race day. The long run starts at 8 km and is always run at easy pace.
How many days a week do I need to run?
Three to six. This sample uses 4. On three days the peak week is 32.5 km (20.2 mi); the long run is the same whatever you choose. Pick the number you can keep up every week, not the most you can manage once.
What should I do if I miss a week?
Pick the plan up at the current week rather than trying to make the missed runs up. If you miss more than a week, rebuild the plan in the planner from today's date: it counts back from race day again and chooses a length that still fits.
Can I print the plan or put it in my calendar?
Yes. The print button lays this table out on Letter or A4 without the site's menus. The planner builds the same plan for your own goal and race date and exports it as a calendar file for Google, Apple or Outlook, plus a printable PDF. No email or account is needed.
Where do the training paces come from?
From the goal time, through Jack Daniels' VDOT formula. A 50:00 10K gives a VDOT of 40.0. If you have a recent race result, enter that in the planner instead: paces based on current fitness are safer than paces based on a hope.
