Running Pace Splits Calculator
Enter your race distance and goal finish time to get an even-pace plan. The tool shows your target pace and the cumulative time you should hit at every kilometre or mile.
How to plan your race splits
- Enter the race distance and choose kilometres or miles.
- Enter your goal finish time in hours, minutes and seconds.
- Read your target pace and the cumulative split for each mark.
Examples
10 km in 50 minutes
Distance 10 km, goal time 0:50:00
5:00 per km, hitting 5:00 at 1 km, 25:00 at 5 km, 50:00 at 10 km
Frequently asked questions
What does even pacing mean?
Even pacing means covering each kilometre or mile in the same amount of time. The splits here assume a steady effort from start to finish.
Why is the last marathon split a fraction?
A marathon is 42.195 km, so the final entry shows the time at the exact finish distance after the 42 whole-kilometre splits.
Should I run negative splits instead?
Many runners aim to run the second half slightly faster than the first. Use these even splits as a baseline, then adjust if you prefer a negative-split strategy.
Can I plan splits in miles?
Yes. Switch the unit to miles and the splits show the cumulative time at each mile marker.
Does the tool round the pace?
Pace is shown to the nearest second in minutes and seconds, while the cumulative splits round each cumulative time to the nearest second.
