Running Pace Calculator: Pace per km, 2.4km and IPPT Laps

What is your running pace per km?

Your time divided by your distance in km. A 12:00 2.4km is 720 seconds divided by 2.4, which is 300 seconds, or 5:00 per km. Choose what you want to work out below: your pace from a time, your finish time from a pace, or the 2.4km time and laps for a number of IPPT run points.

The calculator assumes an even pace over a measured distance, so treat it as an estimate. It is not medical advice. IPPT times come from MINDEF's 2.4km score table for servicemen, as built into the NS Portal's IPPT calculator, checked 4 November 2026. The half marathon is 21.0975km and the marathon 42.195km, per World Athletics (half marathon, marathon, checked 7 November 2026).

How do you work out running pace by hand?

Turn the time into seconds, divide by the distance in km, then turn the answer back into minutes and seconds. That is your pace per km. Three more numbers follow from it.

1. 01Pace per kmTime in seconds divided by km. 12:00 for 2.4km is 720 divided by 2.4, which is 300 seconds, or 5:00.
2. 02Speed in km/h3,600 divided by the pace in seconds. 3,600 divided by 300 is 12.0 km/h, the number to key in on a treadmill that shows km/h.
3. 03400m lap splitThe pace per km times 0.4. 300 times 0.4 is 120 seconds, or 2:00 a lap.
4. 04Finish timeThe pace per km times the distance. 5:00 per km for 5km is 300 times 5, which is 25:00.

What pace is each 2.4km time?

Each row below is worked out from the 2.4km time in the first column, in 30-second steps from 8:30 to 16:00. A 2.4km is six 400m laps, so the lap split is the time divided by 6. Find your current time or your target and read across. Under 22, 8:30 is full marks on MINDEF's table and 16:00 is the last time that scores a point (1).

What pace do you need for a sub-10 2.4km?

Faster than 4:10 per km, which is 1:40 a lap on a 400m track and 14.4 km/h. A 10:00 run is 600 seconds over six laps, so the laps have to average under 100 seconds. The clock should read under 1:40, 3:20, 5:00 at the ends of laps 1, 2 and 3.

For IPPT, a time counts at or under each 10-second row, so 9:59 scores the same as 10:00: 41 points under 22 and 49 at 40 to 42. Under 22 the next point needs 9:50 (42 points). Every time for all 14 age groups is in the IPPT 2.4km points table.

What 2.4km time and pace does each IPPT score need?

It depends on your age group. Under 22, 43 run points, the run's share of a balanced 85 for Gold, needs 9:40 or faster: 1:36.6 a lap or 4:01.6 per km. At 40 to 42 the same 43 points needs 11:00, or 1:50 a lap.

The columns are the run's share of each balanced route on IPPT score by age, where push-ups and sit-ups score equal points and the rest comes from the run.

Your total also needs push-up and sit-up points, and at least 1 point at every station for any award. The IPPT calculator adds all three stations for your age group.

How do you pace the 6 laps of a 2.4km evenly?

Divide your target by 6 and check the clock at the end of every lap. For a 12:00 the laps are 2:00 each, so the clock reads 2:00, 4:00, 6:00, 8:00, 10:00, 12:00. For a 9:40 it reads 1:36.6, 3:13.3, 4:50, 6:26.6, 8:03.3, 9:40. The IPPT mode of the calculator shows these splits for any age group and run score.

Our coaches set test-day pacing the same way in the 2.4km training plan: the first lap at goal pace or a second slower, even laps after that, and anything left saved for the last 400m. That is our coaching approach, not an official rule. On a route that is not a track, use the pace per km at each km marker instead.

How do you use your pace in training?

Work out your pace from a recent timed run, then your target pace from the time you want. The gap between the two tells you what the training has to close. The 2.4km run training plan turns a target time into a pace for every session over eight weeks, with a check run in week 4 to reset the target.

If the run is for IPPT, look up what your target earns in the IPPT 2.4km points table before you choose it. If you cannot run 2.4km without stopping yet, the training plan starts with a run-walk lead-in.

Anyone with a heart or lung condition, high blood pressure or a recent illness or injury should see a doctor before a timed run, as our IPPT and NAPFA coaching page sets out.
