Pace Calculator (Running/Walking)

The Pace Calculator is the go-to tool for runners, walkers, hikers, and triathletes who want to understand their performance in terms of time per mile or time per kilometer. Unlike speed (which tells you how far you go per unit time), pace flips the relationship: it tells you how long it takes to cover a single unit of distance. Most runners think in pace, not speed — a sub-8-minute mile is a meaningful benchmark, while quoting it as 7.5 mph is less intuitive to most athletes.

Enter your distance and finish time (hours, minutes, and seconds) and the calculator outputs your exact pace in both imperial and metric units, plus your equivalent speed in mph and km/h. This is useful for post-workout analysis, race goal setting, training plan design, and comparing efforts across different distances. A runner who completes a 5-mile run in 42 minutes is running at an 8:24 per mile pace — a concrete benchmark to track progress toward a goal.

Pace is also the foundation of race time prediction. If you know your current 5K pace, you can estimate your 10K, half marathon, and marathon finish times using standard race equivalency tables. This calculator gives you the precise pace value you need to feed into those projections. The km/h and mph outputs allow direct comparison with treadmill settings, cycling speeds, and vehicle speeds for cross-sport context.
