Running Pace Calculator

Running pace calculator for miles or kilometers with pace per unit, average speed, and same-pace 5K and 10K projections.

Convert a completed distance and elapsed time into average pace and speed. Same-pace projections are simple arithmetic, not a prediction of race performance.

Terrain, weather, stops, measurement accuracy, fatigue, and fitness affect real results. Increase training gradually and seek qualified guidance for health concerns.

Frequently asked questions

Is the race projection a performance prediction?

No. It only extends the same average pace to another distance.

What is pace?

Pace is elapsed time per mile or kilometer; lower time generally means faster movement.

Can I use walk-run intervals?

Yes. The result is the overall average across the full elapsed time entered.
