Pace Calculator

Calculate pace, finish time, or distance

Use any two known values to solve the third, compare kilometre and mile pace, and generate even splits.

Your run

Pace assumes a constant average speed. Hills, stops, weather, terrain, and fatigue can change real-world splits.

How the pace calculator works

Pace is time divided by distance. Speed is distance divided by time. The calculator converts every entry to seconds and kilometres first, then returns both min/km and min/mile so the same result is useful for metric and US training plans.

When you calculate finish time, the selected pace is multiplied by the distance. When you calculate distance, total time is divided by pace. The split schedule assumes even pacing from start to finish.

Using pace for training and races

  • Use a recent, representative effort rather than your fastest short sprint.
  • Allow for hills, heat, wind, trail surfaces, aid stations, and crowding.
  • Start conservatively in longer events and compare actual splits with the plan.
  • Use kilometre or mile markers that match your race course.

Frequently asked questions

What is the difference between pace and speed?

Pace is the time needed to cover one unit of distance, such as minutes per kilometre. Speed is the distance covered in one hour.

Why does the mile pace look slower?

A mile is longer than a kilometre, so the time per mile is numerically larger even though the underlying speed is identical.

Are projected splits guaranteed?

No. They are mathematical even-pace targets, not a performance prediction. Conditions and fatigue can make actual results different.

Exercise safety note

Increase training gradually. Stop exercising for chest pain, faintness, severe breathlessness, or unusual symptoms. Seek medical guidance before vigorous exercise if you have a health condition, are returning after a long break, or have been advised to limit activity.
