How to pace a 5K

To pace a 5K, divide your goal time by 3.107 miles or 5 kilometers. A 25:00 goal needs 8:03 per mile, or 5:00 per kilometer. Check your elapsed time at each kilometer against the split table, and keep the early kilometers close to goal pace.

Step 1: pick a goal time you can justify

Base the goal on a recent result. If you have a recent 10K or half marathon, use the race time predictor to estimate a 5K time. The formula behind it was well calibrated up to the half marathon in a study of 2,303 recreational runners.[2] Treat the answer as a starting point. To see how typical race entrants pace, see the average running pace by distance.

Step 2: convert the goal to pace

Divide the goal time by the distance. A 5K is exactly 5,000 meters, or 3.107 miles. This table gives the pace for common goals.

Goal timePer milePer kmmph
18:005:483:3610.36
20:006:264:009.32
22:307:154:308.28
25:008:035:007.46
27:308:515:306.78
30:009:396:006.21
35:0011:167:005.33

For any other goal, use the 5K pace calculator.

Step 3: write down your splits

For a 25:00 goal at an even pace, you want these elapsed times.

KilometerElapsed
1 km5:00
2 km10:00
3 km15:00
4 km20:00
5 km25:00
MileElapsed
Mile 18:03
Mile 216:06
Mile 324:08
3.107 miles (finish)25:00

Use whichever markers your course shows. Choose your own goal in the calculator to get the exact table.

Step 4: start under control

A 5K lasts well over 2 minutes for almost every runner. A review of pacing research found that in events longer than about 2 minutes, distributing pace more evenly may improve times.[1] In practice, that means keeping the first kilometer close to goal pace. The guide to negative splits and even pacing explains what the research does and does not show.

Common mistakes

  • Choosing a goal from a hope instead of a recent result.
  • Reading decimal minutes as minutes and seconds. See how to calculate running pace.
  • Trusting the watch pace in the first minutes, when GPS can read unsteadily. Check the elapsed time at the marker as well.
  • Forgetting the course. Hills and wind change splits, so adjust the plan.

Frequently asked questions

What pace is a 25-minute 5K?

A 25:00 5K is 8:03 per mile, or 5:00 per kilometer. That is 7.46 mph. At that pace you reach the 1 km mark at 5:00.

How do I convert my 5K goal to pace per mile?

Divide the goal time by 3.107. For a 30:00 goal, 30:00 ÷ 3.107 = 9:39 per mile.

Should I run a 5K at an even pace?

The pacing review found that in events longer than about 2 minutes, distributing pace more evenly may improve times. A 5K is in that range for almost every runner.
