Running Pace Calculator
Calculate your pace from a distance and time, or predict a finish time for a race.

How to Use the Pace Calculator
- Enter a distance and time to find your pace per mile and per kilometer.
- Enter a race distance to predict a finish time at that same pace.
Frequently Asked Questions
How is pace different from speed?
Speed is distance covered per unit of time (like miles per hour), while pace is the inverse — time taken per unit of distance (like minutes per mile). Runners typically think in pace since it directly answers "how long will each mile take."
Can I predict my finish time for a race distance using my pace?
Yes — enter your pace and the target race distance in the second section, and it multiplies your per-mile or per-kilometer pace by the total distance to estimate a finish time.
Does this account for pacing changes during a race, like fatigue?
No — this assumes a perfectly even pace throughout, which is a simplification. Real race performance often varies due to terrain, fatigue, and pacing strategy, so treat the prediction as a rough estimate rather than a guarantee.
