Pace Table & Split Calculator

Set a target time for any race distance and see the pace per km and every kilometre split.

How to use

  1. Select the race distance and type your target finishing time.
  2. Click Calculate to see the pace per km.
  3. The full split table shows your cumulative time at every kilometre.

About this tool

A pace table translates a target finishing time into the pace you need to hold per kilometre, and shows your cumulative time at every split. For a 5K in 25:00, you need a pace of 5:00/km — and at km 3 you should be at 15:00.

Even splits are the fastest strategy for most runners. Negative splits — running the second half slightly faster than the first — work too, but positive splits (going out too fast) almost always result in a slower total time because the slowdown in the last kilometres costs more than the early speed gained.

This tool assumes perfectly even splits. On a hilly course, adjust uphill splits +10-15 seconds and downhill splits −5-10 seconds per km. The cumulative time is the same; the distribution changes.

The formula

Pace = total time / distance. Split at km N = pace × N.

Frequently asked questions

What is a pace?

The time it takes to run one kilometre, expressed as minutes and seconds per km (e.g. 5:30/km).

What are negative splits?

Running the second half faster than the first. Many coaches recommend it as a pacing strategy for races.

Can I use this for miles?

The tool uses kilometres. To convert, multiply the pace by 1.609 (e.g. 5:00/km ≈ 8:03/mi).
