Pace Calculator

Turn a finished distance and a clock time into even pace — minutes per kilometre or per mile. Empty hours or seconds count as zero. Hills, wind and splits are invisible; this is time divided by course distance.

How to use

  1. Choose kilometres or miles so the pace unit matches the course you ran or plan to run.
  2. Enter the distance, then hours (optional), minutes, and seconds (optional).
  3. Read pace as minutes:seconds per km or per mile. 10 km in 50:00 is 5:00 /km.
  4. Use Calories Burned if you want a MET estimate for the session, not a pace. This page does not prescribe training.

How it works

Pace is total elapsed time divided by distance. Fifty minutes is 3,000 seconds; over 10 km that is 300 seconds per kilometre, which displays as 5:00 /km. Switch the distance unit to miles and the same time over 6.21 mi (if that is what you typed) becomes min/mile. The calculator does not convert a kilometre result into a mile result for you in one step — pick the unit that matches the course.

Hours and seconds are optional so a 5 km in 24:30 does not need a 0 in the hours box. Blank means zero. A marathon time of 3:15:00 is three hours plus 15 minutes. The result is even-split pace: it assumes every kilometre or mile took the same time. A GPS watch that slowed on hills will show a different average and different kilometre splits.

This is not a race predictor and not a heart-rate zone. It will not tell you what to run next week. Target Heart Rate is a different page (Tanaka HRmax and optional Karvonen). Calories Burned uses a MET table and body weight, not pace.

Course distance is the official or measured length you enter. If the route was short or long, the pace is still “time ÷ the number you typed.” Indoor track, treadmill belt and road calibration all disagree with each other; the algebra does not care.

Not medical advice. Stop if you feel unwell. The fitness disclaimer applies even though the inputs look like race results. A 5 km in 24:30 is 4:54 /km (1,470 seconds ÷ 5). A half marathon (21.1 km) in 1:45:00 is about 4:59 /km. Those are even splits; if you positive-splitted the second half, the average still looks like the single number this page prints.

Formula

pace = total time ÷ distance

Worked examples

  • A 10 km

    10 km in 50 minutes → 5:00 /km

Useful notes

  • Even-split average only — not a GPS trace or hill-adjusted pace.
  • Blank hours or seconds are treated as zero.
  • Not medical advice.

FAQ

How do I calculate running pace?

Divide your time by the distance. 50 minutes ÷ 10 km = 5 minutes per km.

Does this account for hills?

No. It is average pace from clock time and course distance.

Can I use miles?

Yes. Switch the distance unit; pace is then min/mile.

Does this predict my next race?

No. It only divides the time and distance you enter. There is no endurance model on this page.

What if I leave hours empty?

Hours and seconds are optional. Empty means zero, so 50 in minutes is 50:00.
