Finish Time from Pace Calculator

Project your race finish time from a target pace.

How it is calculated

The finish time is total = pace × distance, with pace in decimal minutes per kilometre and distance in kilometres. The total in minutes is converted to seconds and rounded to whole seconds, and only then split into hours, minutes and seconds, so a result such as 59.9 seconds carries into the next minute instead of showing 60. It is displayed as h:mm:ss, or as m:ss when under one hour, together with the total in minutes to one decimal. A pace of 5:30 per km must be typed as 5.5, because the field does not read colons and returns nothing for them. The tool accepts only kilometres, not miles. Pace and distance must both be above zero, otherwise there is no result. It assumes an even pace for the whole distance and ignores hills, heat and a fading finish.

Worked example

You aim for a 5:30 pace in a half marathon of 21.0975 km. First convert the pace: 30 s ÷ 60 = 0.5, so the pace is 5.5 min/km. Total time = 5.5 × 21.0975 = 116.036 minutes, which is 6,962 seconds after rounding to whole seconds. That is 1 hour (60 min) plus 56 minutes and 2 seconds. The calculator shows 1:56:02 and 116.0 min in total. Holding 5:15 (5.25) instead would give a finish of about 1:50:46.

Common mistakes

  • Typing the pace as 5.30 for 5:30. That is 5.3 min/km, or 5:18 per km, and makes your projected finish about 4 minutes too fast over a half marathon.
  • Typing the pace with a colon (5:30). The tool cannot read it and returns no result; convert the seconds to a decimal first (30 s = 0.5).
  • Entering a pace per mile. The result is only correct for a pace per kilometre; convert a mile pace first.
  • Using the distance in metres (10000) or in miles. Only kilometres give the right total.
  • Expecting the projected time to account for starting too fast and slowing. The calculation assumes the exact same pace in every kilometre.

About this calculator

This calculator projects a race finish time by multiplying your target pace per kilometer by the total race distance — a straightforward calculation, but one that runners lean on constantly when planning a race strategy, because it turns an abstract pace number into a concrete finish-line clock time.

Runners and running coaches use pace-to-finish-time math to set goal times for 5Ks, 10Ks, half marathons, and marathons, to plan negative-split or even-split strategies (running the second half faster or the same as the first), and to decide which pace group to line up with at the start. It is also how race organizers and pacers ('rabbits') calculate the checkpoints they need to hit along the course to guide runners to a specific goal time.

Enter your target pace in minutes per kilometer (as a decimal, so 5.5 means 5:30) and the distance in kilometers, and this calculator returns the projected finish time and the total in minutes so you can check it against your goal before race day. For a race in miles, convert first: multiply the miles by 1.609 for the distance, and divide your pace per mile by 1.609 for the pace per kilometer.
