is the average time per kilometer.
Per-mile pace is converted from the same exact distance-time ratio.
Segment variation remains outside the average.

Recorded method
Recompute distance-time ratios, time formatting, unit equivalence, and invalid zero boundaries.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- Distance and timing error directly affect pace.
- Stops remain included unless the entered elapsed time excludes them.
- Terrain, surface, weather, drafting, and elevation are not modeled.
- The tool does not prescribe training pace or predict a race result.

What the Pace Calculator answers
Calculate average pace per kilometer and per mile plus speed from one distance and matching elapsed time.
The page keeps pace, speed, units, and elapsed-time formatting separate.
Use the Sports calculators hub to choose the neighboring workflow rather than forcing one result to answer a different question.
How to use the Pace Calculator
- Enter the distance and select its unit.
- Enter elapsed time for that same distance.
- Read per-kilometer and per-mile pace.
- Use a race planner when stops or pacing strategy matter.
Continue with the Running Race Planner. Build checkpoint pacing with stops and start delay.
Formula, variables and calculation order
pace = elapsed seconds / normalized distance; speed = normalized distance / elapsed hours.
Inputs are normalized to the displayed base units, the calculation keeps full precision, and rounding is applied only to visible outputs.
Cross-check the next part of the workflow with the Race Time Predictor. Project another distance with a labeled endurance exponent.
Worked example and boundary check
Worked example
10 km in 50:00 equals 300 seconds per kilometer, shown as 5:00/km, and 12.00 km/h.
Boundary check
A short GPS distance error can materially change pace, especially over short efforts.
How to interpret the result
Use the result to summarize the entered effort; do not infer fitness, race readiness, or safe intensity from pace alone.
- Distance and timing error directly affect pace.
- Stops remain included unless the entered elapsed time excludes them.
- Terrain, surface, weather, drafting, and elevation are not modeled.
- The tool does not prescribe training pace or predict a race result.
For a separate result with different assumptions, open the VDOT Calculator. Estimate a race-performance index from distance and time.
Frequently asked questions
Is pace the same as speed?
No. Pace is time per distance; speed is distance per time.
Can I enter miles?
Yes. The input is normalized before both pace formats are calculated.
Are stops included?
They are included when they are part of the entered elapsed time.
Why does GPS pace differ?
GPS distance smoothing and timing conventions can differ from an official measured course.
