## What pace is a sub-45:00 10K?

To run a sub-45:00 10K, you need to hold **4:30 per kilometre**. That is
**7:15 per mile**, or 13.3 km/h (8.3 mph), held for the whole
10K. Hold that pace evenly from start to finish and you cross the line right on 45:00.
The table below shows the clock at every checkpoint if you run it even. Training indoors, dial the
belt to 13.3 km/h (8.3 mph) directly, or use the [treadmill
pace calculator](https://steadypace.ca/treadmill-pace-calculator) to convert any other pace to a belt speed.

## Sub-45:00 10K splits

| Distance | Target elapsed time |
| --- | --- |
| 1 km | 4:30 |
| 2 km | 9:00 |
| 3 km | 13:30 |
| 4 km | 18:00 |
| 5 km (halfway) | 22:30 |
| 6 km | 27:00 |
| 7 km | 31:30 |
| 8 km | 36:00 |
| 9 km | 40:30 |
| 10 km (finish) | 45:00 |

Even-pace splits for 45:00 over the 10K. Aim to reach halfway a few
seconds behind these and finish a few ahead. A slight [negative
split](https://steadypace.ca/guides/negative-splits) is safer than banking time early.

## Is a sub-45:00 10K a realistic goal?

It depends on where you are now, but the honest test is whether you can already hold close to
4:30 per kilometre for a shorter effort. This is a serious club-runner time, close to the pace many people can only just hold for a standalone 5K, now needed for double the distance. Threshold training closes this gap faster than adding more easy volume does.

The 10K sits on your threshold, the effort you can just hold. Train it with tempo runs and longer intervals (say, 1 km repeats at goal pace), plus easy volume. Race the middle evenly; do not bank time in the first 2 km.

## What times does sub-45:00 10K pace predict at other distances?

If you can run a sub-45:00 10K, you're roughly capable of these times at other distances, estimated
with the Riegel formula, which scales a known time by distance. Real results vary with training and
terrain, but it's a useful reality check.

| Distance | Equivalent time | Pace / km |
| --- | --- | --- |
| 5K | 21:35 | 4:19 |
| 10K (this goal) | 45:00 | 4:30 |
| Half marathon | 1:39:17 | 4:42 |
| Marathon | 3:27:01 | 4:54 |
| Mile | 6:29 | 4:02 |

## How do you hold sub-45:00 10K pace on the day?

Know the number, then hold it evenly. Most people miss a goal like this by starting too fast and
fading late, when they still had the fitness to finish. Read the full [10K pacing guide](https://steadypace.ca/guides/how-to-pace-a-10k),
work splits with the [pace calculator](https://steadypace.ca/pace-calculator), and see how this pace compares
on the [pace charts](https://steadypace.ca/pace-chart).

Set **4:30/km** as your target in
[Steady Pace](https://apps.apple.com/app/steady-pace/id6773682525) and hold it by ear:
a tone rises the moment you slow below sub-45:00 10K pace and falls when you drift too fast, so you catch the
surge in the first kilometre instead of the last.

**What pace do I need for a sub-45:00 10K?**

4:30 per kilometre, or 7:15 per mile, held for the full 10K (10 km). At that pace you finish in 45:00.

**How do I convert sub-45:00 10K pace to miles?**

4:30 per kilometre is 7:15 per mile. Multiply the per-km pace by 1.609. Over the 10K that adds up to a 45:00 finish.

**Should I run a sub-45:00 10K as an even or negative split?**

Even, or a slight negative split. Reach halfway just behind goal pace and finish just ahead. Going out faster than 4:30/km almost always costs you more time later than it saves early.
