How it works
Finish time = distance × pace per km.

Common mistakes
- Entering pace and speed in mismatched units — keep min/km with km, or min/mi with miles.
- Assuming even pacing on a hilly course, where the real finish drifts from the estimate.
Tips
- Times are estimates only — not medical or coaching advice. Always train safely and follow event rules.
- Distances are editable: choose “Custom…” to enter your own course lengths.
Frequently asked questions
How is finish time calculated?
Finish time = distance × pace, or distance ÷ speed. The tool keeps the units consistent so the figure is reliable.
Should I plan for even or negative splits?
Most strong races are run even or slightly negative — a touch faster in the second half — rather than starting fast and fading.
Pace or speed?
Enter your steady pace per km; the tool also shows the equivalent speed.
