About Pace to Finish Time
The Pace to Finish Time calculator tells you exactly how long a run will take from the pace you plan to hold.
Enter your target pace in minutes and seconds, pick whether that pace is per kilometre or per mile, then set the race distance in kilometres or miles.
The tool normalises everything internally and shows your projected finish time formatted cleanly as hours, minutes and seconds.
This is the number runners actually care about on race day.
If you know you can hold five minutes per kilometre, what does that mean over a half marathon? If your goal is a sub-four-hour marathon, what pace per mile does that demand? Because you can mix units freely — a mile pace against a kilometre distance, or the reverse — it works no matter how your watch or race is measured.
The result updates live as you adjust any field, so you can experiment with race strategy and even-split planning in seconds.
All calculations happen locally in your browser using simple, transparent arithmetic; nothing is uploaded or tracked.
It is handy for 5K, 10K, half marathon and full marathon planning, and the copyable finish time slots neatly into a training log or pacing band.
FAQ
Can I mix kilometres and miles?
Yes. You can set a per-mile pace against a distance in kilometres, or any other combination; the tool converts everything consistently.
Does this account for fatigue or hills?
No. It assumes you hold an even pace for the whole distance, which is ideal for goal setting and even-split planning.
