5K Pace Calculator

About this calculator

This calculator converts between a target finish time for a 5 kilometer race and the pace per kilometer or mile needed to achieve it, using the straightforward relationship between distance, time, and speed. Entering a goal time reveals the exact pace to hold throughout the run, while entering a pace reveals what finish time it would produce.

Runners training for a 5K use it to plan pacing strategy before a race, checking whether a goal time is realistic based on recent training paces, or setting mile or kilometer split targets to hit during the run itself. It's also used to convert race results between different pace and time formats when comparing performances.
