Sub 42 min 10K pace
To run a 10K under 42:00 you need to average 4:12 per kilometre, or 6:45 per mile. Here are the splits, a pace band, the paces to train at and the fitness you need before race day.

Splits
Even pace versus a 1 % negative split. Both finish exactly on 42:00; aim to cross the line a little inside it.
| Point | Even pace | 1 % negative |
|---|---|---|
| 1 km | 4:12 | 4:13 |
| 2 km | 8:24 | 8:27 |
| 3 km | 12:36 | 12:40 |
| 4 km | 16:48 | 16:53 |
| 5 km | 21:00 | 21:06 |
| 6 km | 25:12 | 25:17 |
| 7 km | 29:24 | 29:28 |
| 8 km | 33:36 | 33:39 |
| 9 km | 37:48 | 37:49 |
| Finish | 42:00 | 42:00 |
Race times that match this goal
Equivalent performances from Riegel's formula. If you can run these, sub 42 min is realistic with the right training.
Training paces for sub 42 min
| Run type | Pace /km | Zone | Typical session |
|---|---|---|---|
| Recovery | 5:47–6:30 | Zone 1 | Between hard days, 20–40 min |
| Easy and long runs | 5:14–5:47 | Zone 1–2 | Most of your weekly volume |
| Marathon pace | 4:32–4:38 | Zone 2–3 | Long-run segments of 8–20 km |
| Threshold | 4:13–4:22 | Zone 3–4 | 3 × 10 min or 20–30 min steady |
| Interval (VO2max) | 3:54–4:02 | Zone 4–5 | 5 × 1000 m, 3 min jog |
| Repetition | 3:44–3:48 | Zone 5 | 8 × 200–400 m, full recovery |
What it takes
Most runners who break 42 min in the 10K build to about 30–45 km a week over 8–10 weeks, with long runs of 12–16 km. The key sessions are threshold runs and intervals of 1–2 km around 10K pace.
A 5K around 20:09 three to four weeks before the race is a good checkpoint. If you are slower than 20:45, aim for sub 45 min instead and adjust after your next test.
Weekly volumes are typical ranges, not requirements. Build up gradually and adjust to your own history.
Common questions
How fast is sub 42 min 10K pace per mile?
6:45 per mile, or 4:12 per kilometre.
What 5K time do I need for a sub 42 min 10K?
Around 20:09 on Riegel's formula, assuming training that is specific to the 10K.
Should I run even splits?
Yes, or a very slight negative split. Starting faster than goal pace costs far more time late in the race than it gains early.
