# Half Marathon Pace Calculator: Plan Your Target Pace

Welcome to our Half Marathon Pace calculator.

This calculator gives you your target pace and even time splits for a half-marathon race based on your target race time.

The results are shown in both miles and kilometers.

To achieve your target race time, your average speed needs to be the same as the target pace given by the calculator or faster.

## What Should My Half Marathon Pace Be?

Your half marathon pace should reflect your finish time goal for the race.

For more info on how to decide your pacing and time goals, check out our definitive guide to marathon pacing.

## How to Calculate Half Marathon Pace?

Half-marathon pace is calculated by dividing your target half-marathon time by the half-marathon distance (13.11 miles or 21.10 kilometers).

If you want to calculate pace yourself, you need to make sure all of the units are properly converted. For example, a target time of 3 hours and 30 minutes needs to be converted to minutes before being calculated.

Luckily, the calculator does these conversions for you.

## What Are Split Times? Split Times In Running Explained

A split is a timed section of your run. A split time is typically given for each kilometer or mile of your run. Split times allow runners to break up their run into smaller sections so they can better monitor their speed and progress throughout the run.

Nowadays, most GPS running watches give you the option to log split times for every kilometer or mile.

Some runners aim for even splits, whereby the same amount of time is taken to complete each section of the run. This means that the speed of the runner remains relatively consistent throughout the race.

Other runners aim for negative splits, whereby sections in the second half of the run are completed in less time, meaning that the second half of the race is run faster than the first half of the race. The aim of this is to better maintain a manageable pace, stop burn-out, and give an extra boost of energy and speed towards the end of the race.
