    How Running Pace Works

    Pace is expressed as time per unit of distance, most commonly minutes per kilometer (min/km) or minutes per mile (min/mi). A pace of 5:00/km means each kilometer takes exactly 5 minutes. Pace is the inverse of speed: a faster runner has a lower pace number.

    Pace = Total Time / Distance

    Example: 50 minutes over 10 km = 5:00/km pace. 4 hours for a marathon (42.195 km) = 5:41/km pace.

    Negative Splits: The Smart Racing Strategy

    Negative splits means running the second half of a race faster than the first. Most beginners run the first half too fast and slow dramatically by mile 18+ in a marathon. Starting 10-15 seconds per km slower than goal pace for the first third of the race preserves glycogen and results in faster finish times. Nearly every marathon world record has been set with negative or even splits.

    Frequently Asked Questions

    What is a good running pace?

    It depends entirely on your fitness and experience. A beginner runner might run 7-8 minutes per km (11-13 min/mile). An average recreational runner hits 5-6 min/km (8-10 min/mile). A competitive age-group runner runs 4-5 min/km (6-8 min/mile). Elite marathon runners hold 2:50-3:10 per km (4:30-5:00 per mile).

    How do I calculate my pace?

    Divide your total run time (in minutes) by the distance. If you ran 5 km in 28 minutes, your pace is 28/5 = 5:36 per km. Convert the decimal to seconds: 0.6 minutes = 36 seconds, so 5 min 36 sec per km.

    What pace do I need to run a 2-hour half marathon?

    2 hours for 21.098 km = 5:41 per km (9:09 per mile). To safely hit this, train at about 5:50-6:00/km for most long runs and do speed work at 5:15-5:20/km.

    What is the difference between pace and speed?

    Speed is distance divided by time (km/h or mph). Pace is time divided by distance (min/km or min/mi). Runners prefer pace because it directly tells you how long each kilometer or mile will take. A pace of 5:00/km equals a speed of 12 km/h.

    How do I convert min/km to min/mile?

    Multiply your min/km pace by 1.60934. A 5:00/km pace equals 5 x 1.60934 = 8:03 per mile. To convert min/mile to min/km, divide by 1.60934.
