## What pace is a sub-18:00 5K?

To run a sub-18:00 5K, you need to hold **3:36 per kilometre**. That is
**5:48 per mile**, or 16.7 km/h (10.4 mph), held for the whole
5K. Hold that pace evenly from start to finish and you cross the line right on 18:00.
The table below shows the clock at every checkpoint if you run it even. Training indoors, dial the
belt to 16.7 km/h (10.4 mph) directly, or use the [treadmill
pace calculator](https://steadypace.ca/treadmill-pace-calculator) to convert any other pace to a belt speed.

## Sub-18:00 5K splits

| Distance | Target elapsed time |
| --- | --- |
| 1 km | 3:36 |
| 2 km | 7:12 |
| 3 km | 10:48 |
| 4 km | 14:24 |
| 5 km (finish) | 18:00 |

Even-pace splits for 18:00 over the 5K. 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-18:00 5K a realistic goal?

It depends on where you are now, but the honest test is whether you can already hold close to
3:36 per kilometre for a shorter effort. This pace is inside the range of competitive high-school and college distance runners. Reaching it as an adult recreational runner almost always takes years of structured mileage and a real speed background.

The 5K rewards speed you can sustain. Sharpen it with intervals (repeats at or a touch faster than goal pace) and a weekly tempo run, on a base of easy miles. Race it even or a whisker negative. The first kilometre is the one people spend too fast.

## What times does sub-18:00 5K pace predict at other distances?

If you can run a sub-18:00 5K, 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 (this goal) | 18:00 | 3:36 |
| 10K | 37:32 | 3:45 |
| Half marathon | 1:22:48 | 3:55 |
| Marathon | 2:52:38 | 4:05 |
| Mile | 5:25 | 3:22 |

## How do you hold sub-18:00 5K 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 [5K pacing guide](https://steadypace.ca/guides/how-to-pace-a-5k),
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 **3:36/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-18:00 5K 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-18:00 5K?**

3:36 per kilometre, or 5:48 per mile, held for the full 5K (5 km). At that pace you finish in 18:00.

**How do I convert sub-18:00 5K pace to miles?**

3:36 per kilometre is 5:48 per mile. Multiply the per-km pace by 1.609. Over the 5K that adds up to a 18:00 finish.

**Should I run a sub-18:00 5K 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 3:36/km almost always costs you more time later than it saves early.
