Free Running Pace Calculator

Calculate running pace from distance and time, and see projected finish times at the same pace for 5K, 10K, half marathon, and full marathon. Supports kilometres and miles.

Common Uses

Plan negative-split race strategies
Check whether training paces match goal times
Convert finish times into pace per km/mile
Pick treadmill speed from a target pace
Track progress across training blocks

How It Works

Pace is computed as time divided by distance, then converted to minutes and seconds per unit. Speed is the inverse, in km/h or mph. Race projections multiply the per-unit pace by each race's standard distance.
