Pace is a fast and clean running calculator for planning races, workouts, splits, and finish times.

Enter any two values — pace, time, or distance — and Pace instantly calculates the third. Whether you are preparing for a 5K, 10K, half marathon, marathon, or a custom distance, the app helps you understand your target pace and plan your effort before race day.

Pace is designed for runners who want clear numbers without clutter. Big tabular time readouts, a dark athletic design, and clean split tables make it easy to read your target pace at a glance.
