The Pace Calculator converts running distance and time into pace per mile or kilometer, or predicts race times. This Pace Calculator uses an established clinical or fitness formula to give you a personalised estimate in seconds.

The formula behind this calculator: Pace = time / distance; race predictions scale a known pace by distance using standard endurance formulas. As a practical example: Running 5K in 25 minutes is an 8:03/mile pace. All results are calculated instantly in your browser — no data is stored or transmitted.
