Pace Calculator

How the pace calculator works

Pace is the amount of time it takes to cover a set distance. We convert your total time into seconds and divide by distance to get seconds per kilometer (or mile). That value is formatted back into minutes and seconds so you can compare against training plans or race goals.

Formulas used

Pace: pace (sec/unit) = total time (sec) ÷ distance (unit).
Speed: speed (km/h or mph) = distance ÷ time (hours).
Projected time: projected time = pace (sec/km) × target distance (km).

Using projections wisely

Projected times assume you hold the same effort across longer distances. For realistic race goals, combine these estimates with recent workouts, terrain, weather, and how long you can comfortably maintain the pace.

Pace calculator FAQ

How do I calculate running pace?

Divide total time by distance. The calculator converts your time to seconds, divides by distance, and formats the result as minutes per kilometer or mile.

What is the difference between pace and speed?

Pace is the time it takes to cover one unit of distance, while speed is distance per hour. They are inverses of each other.

Can I use this for walking or cycling?

Yes. Enter any distance and time to get pace and speed. The units will adjust automatically.

Why are projected times only estimates?

Projections assume you can hold the same pace across longer distances. Real race times vary with terrain, fatigue, and conditions.

Should I track pace in minutes per mile or kilometer?

Use the unit you train with. The calculator toggles between metric and imperial so the results match your preference.
