Pace Calculator
Work out your running pace, total time, or distance covered — then see what that pace means for standard race distances.

Splits above assume you hold the same pace for the whole distance. Real race times vary with terrain, weather, and pacing strategy, so treat these as ballpark estimates.
How Pace Is Calculated
Pace is simply how long it takes you to cover one unit of distance, usually shown as minutes per kilometer or minutes per mile. It’s the inverse of speed, and the three values below are all derived from the same relationship.
Once your pace is known, it can be applied to any distance to estimate a finish time — which is how the standard race splits on the right are calculated.
Frequently Asked Questions
What’s the difference between pace and speed?
Pace tells you how much time it takes to cover one unit of distance (minutes per km or mile), while speed tells you how much distance you cover in one unit of time (km/h or mph). Runners typically think in pace; cyclists and drivers typically think in speed.
Why does my GPS watch show a different pace?
GPS watches measure pace in real time based on satellite signal, which can drift slightly under tree cover, tall buildings, or tight turns. This calculator gives you an exact average pace based on the total distance and time you enter.
What is a good pace for a beginner?
There’s no universal “good” pace — it depends on your fitness level, age, and goals. Most beginners aim for a comfortable, conversational pace first and gradually work toward specific time goals as fitness improves.
Should I run the same pace for a whole race?
An even or slightly negative split (running the second half a little faster than the first) is generally considered the most efficient race strategy, since starting too fast often leads to a significant slowdown later on.
