Many runners turn up to parkrun or a 5k with a time in mind, but no real idea of what that actually means for each kilometre or lap. A simple parkrun pace calculator and pace table turns your goal time into clear split targets so you can run more evenly, avoid blowing up, and give yourself the best chance of a PB.​

What this parkrun pace calculator does

The parkrun pace calculator and pace table on this page lets you:

• Set a range of 1 km paces (for example, from 5:00/km to 6:00/km).
• Choose how big a step you want between rows (for example, 10 seconds).
• See the equivalent times for common track distances (100 m–800 m) and for 5k at each pace.​

That means you can use the same tool to plan your parkrun pacing and to design interval sessions that match your current fitness.

How to use it for parkrun

To use this parkrun pace calculator for parkrun or any 5k:

• Decide your goal time. For example, maybe you’d like to run around 30 minutes or dip under 25 minutes.​
• Convert that into an approximate 1 km pace (30 minutes is about 6:00/km; 25 minutes is about 5:00/km).
• Put your target pace range into the “Start 1K pace” and “End 1K pace” boxes, and choose an increment that gives you a useful spread of options.

On the start line, you then have a clear idea of roughly how fast each kilometre or lap should feel, rather than just hoping it all works out.

Using it for training sessions

The table is also useful between parkruns when you are doing interval or tempo runs:

• Tick the shorter distances (100–800 m) to see how long each rep should take at your chosen pace.​
• Use slightly faster than 5k pace for short intervals, and slightly slower than 5k pace for longer tempo efforts, so your training is structured rather than random.

You can save or screenshot paces that feel right for you, and update them as your fitness improves.

Remember: tools plus how your body feels

A pace table or calculator is a great guide, but it can’t tell you how rested you are, whether you’re coming back from injury, or what else is going on in your life. It is fine to adjust your target on the day if conditions, sleep or stress mean your original plan is unrealistic.​

If you are regularly struggling to hold your chosen pace, or keep picking up niggles when you try to run faster, it can help to get some tailored advice on running form, strength and training structure alongside using tools like this.
