What is half marathon pace?
Your half marathon pace is the average speed you need to hold across all 13.1 miles to hit your goal time. Unlike a 5K where you can push hard from the start, a half marathon rewards even pacing — starting 10–15 seconds per mile slower than goal pace and negative splitting the back half is the most reliable strategy for most runners.
How to use this calculator
Enter your goal finish time above. The calculator shows your required pace per mile and per kilometer, plus split times at every 5K checkpoint through the finish. Use the split table to set your GPS watch, brief your crew, or check your pacing during the race.
What comes after the calculator?
