Question 1

What does pacing mean?

Answer

Pacing refers to the speed at which you run a set distance, for example a kilometer or a mile. During races, pacing is all about finding that sweet spot to run the whole distance effectively without burning out too early.

During training, the different pacing strategies you use enable you to gradually improve your performance over time, for example with tempo or interval runs.

Pacing is typically measured in minutes per kilometer or per mile, which is the average time it’d take you to cover this specific distance.

Question 2

How do you pace your runs?

Answer

You can use a GPS watch or your smartphone to keep an eye on your pace and distance. If you’re using a training app like Runna, then you can simply follow the instructions you get during each run.

As for races, use our pace calculator to figure out your ideal pace based on your goal. Then, break the run into chunks, and either use a negative split (where you go slower at first and then increase your speed) or try to keep your pace steady throughout. And, of course, listen to your body and adjust as needed.

Question 3

Why do you need to pace your runs?

Answer

Pacing is key to running smarter, not just harder. It helps you manage your energy, so you don't burn out too soon and can finish strong.

Question 4

What’s the best pacing strategy for a race?

Answer

You can use a GPS watch or your smartphone to keep an eye on your pace and distance. If you’re using a training app like Runna, then you can simply follow the instructions you get during each run.

As for races, use our pace calculator to figure out your ideal pace based on your goal. Then, break the run into chunks, and either use a negative split (where you go slower at first and then increase your speed) or try to keep your pace steady throughout. And, of course, listen to your body and adjust as needed.A common pacing strategy for a race is a negative split, where you start slightly slower than your goal pace, maintain a steady middle, and go all in towards the end for a strong finish.

Question 5

How fast do I need to run to get an 18 minute 5k?

Answer

Answer

Here are a few examples for 5k goal times and their respective paces:

If your goal is to finish in 35 minutes, you need a 5k pace of 7:00/km or 11:15/miles
If you’re aiming for a 32-minute finish time, you need to run at a pace of 6:24/km or 10:17/miles
If you want to finish in 30 minutes, you need a pace of 6:00/km or 9:39/miles
If you’re aiming for a 25 minute 5k, then your overall 5k pace needs to be 5:00/km or 8:03/mile
For a sub-20 minute 5k race, you need to run at 3:59/km or 6:25/mile pace
For a 18-minute 5k race, you’re looking at a 3:36/km or 5:47/mile pace

Question 8

Pacing a 5k: What is the best way to pace a 5K?

Answer

Pacing a 5k is quite straightforward.

First, figure out your goal time. For example, if you want to finish in 30 minutes, you need a pace of 6:00/km or 9:39/miles

There are two main ways to pace a 5k:

Aim to hit your goal pace from the start and stick to it – a 5k is sufficiently short for that
Use a negative split, which is a popular 5k pacing strategy. Start a few seconds slower than your goal pace. From the 2nd kilometer onwards, stick to your goal pace.

In both cases, in the last kilometer, you can give it all you’ve got – this is where things will get difficult, but it’s only going to last a few short minutes.

Question 9

What is a reasonable 5k pace?

Answer

Pacing a 5k depends entirely on your current running level.

If you’re a beginner, simply aiming to run a 5k without stopping can be one of your first goals (and certainly one you can be proud of!)

Once you achieve that, you can then aim to bring down your 5k finishing time.

Runna can help with both:

If you’re a beginner, try out our New to running training plans to get started and build a running routine
If you’re already able to run a 5k comfortably, use our 5k improvement training plans to level up your running game and set a new personal record

Question 10

How do I determine my 5k pace?

Answer

To set a 5k pacing goal, you can use the pace calculator above; for example, you can aim to beat your previous personal best. The faster you are, the harder it’ll be to get even faster, so keep that in mind when deciding on your 5k pacing goal.

Question 11

Should you run a 5k at the same pace?

Answer

You can definitely do that. In this case, simply try to stick to your goal pace throughout the race.

Question 12

How do I improve my 5k pace?

Answer

The best way to improve your 5k pace is to use a structured 5k training plan, featuring a combination of interval training, tempo runs, long runs, and easy runs.

Question 16

What should be my goal time for 10k – and what’s the right pace for my 10k goal?

Answer

Determine your goal time based on your previous personal best; keep in mind that the faster you are, the harder it will be to set a new personal record.

Then, figure out your ideal pace with our calculator above. For example:

To finish in 1 hour and 10 minutes, that’s a 10k pace of 7:00/km or 11:15/mile
To finish just under an hour, you’d need a 10k pacing effort of 5:59/km or 9:37/mile
For a 55-minute finish, that’s a pace of 5:30/km or 8:51/mile
For a 50-minute finish, you need a 10k pace of 5:00/km or 8:02/mile
For a 45-minute finish, your pace needs to be 4:30/km or 7:14/mile

Question 17

What is the best way to pace a 10k?

Answer

One of the most popular 10k pacing strategies is a negative split:

First 3k (miles 0-2): Start around 5s/km slower than your target pace; try to not go out too fast in the beginning.
4-7k (miles 3-4): Gradually increase your pace to your 10k target pace
From 7k (miles 4-6.2): Pick your moment to go faster; if you’re feeling good, this can be from 7k (which is approx. mile 4) but if you are struggling, you can do that at the 8k or even 9k mark
From 9k: Give it all you’ve got for a strong finish

Question 18

What is a reasonable 10k pace?

Answer

That depends entirely on your current running level.

A good 10k time for beginner and intermediate runners is around 55 minutes or under for women, which requires an average pace of 5:30/km or 8:51/mile, or 45 minutes or under for men, requiring a pace of 4:30/km or 7:14/mile.

Elite male runners are generally able to run a 10k in 40 minutes or under, which translates to a pace of 4:00/km or 6:26/mile. Elite female athletes are able to run a 10k in 45 minutes or under, which requires a 10k pacing effort of 4:30/km or 7:14/mile.

At the moment, for women, the world record is 29:01 and 26:11 for men.

If you’re a beginner but already can run a 5k without walking, running a 10k can be your next goal. Once you achieve that, you can then aim to finish your next 10k faster, and then to improve your finishing time further.

The best way to do this is by using a dedicated running coaching app like Runna. Our 10k training plans feature a mix of interval training, tempo runs, long runs, and easy runs – plus optional strength training for runners – to help you improve your 10k pace.

Answer

Becoming a faster runner requires following a structured 10k training plan with a combination of different types of training sessions, such as interval training, tempo runs, long runs, and easy runs.

The faster you are, the harder it’ll be to become even faster. If you’ve hit a plateau, a 10k training plan can help you break through it.

Question 21

Should you run a 10k at the same pace?
