Questions
How do I calculate my running pace?
Divide your time by your distance. For example, 50 minutes for 10 km is 50 ÷ 10 = 5:00 per km, or 8:03 per mile (one mile is 1.609344 km). Enter the distance and time in the calculator above and it does the division and shows both units.
What pace is a 4-hour marathon?
9:09 per mile, or 5:41 per km, held for 26.2 miles (42.195 km). Run slightly faster than that if you want a time under 4:00:00, because extra distance from weaving and corners adds up.
What pace do I need for a sub-2-hour half marathon?
An average of 9:09 per mile or 5:41 per km. Exactly 2:00:00 for 13.1 miles works out to 9:09.5 per mile, so 9:09 or faster gets you under two hours.
What pace is a 3-hour marathon?
3:00:00 averages 6:52 per mile (4:16 per km), but both round down: to finish under three hours you need 6:51 per mile or 4:15 per km.
What pace is a 30-minute 5K?
9:39 per mile, or 6:00 per km. A 25-minute 5K is 8:03 per mile or 5:00 per km.
How do I convert pace per mile to pace per km?
Divide the pace per mile by 1.609344. For example, 8:00 per mile is 480 seconds ÷ 1.609344 = 298 seconds, or 4:58 per km. To go from per km to per mile, multiply by 1.609344.
What are even splits?
Even splits mean running every mile or kilometre at the same pace. The calculator lists the time for each split and your elapsed time, so you can check your watch against a goal during a race.
How it's calculated
Pace is your time divided by your distance. A mile is 1.609344 km; a half marathon is 21.0975 km (13.11 miles) and a marathon 42.195 km (26.22 miles). Finish time is pace multiplied by distance, and splits assume you run every mile or km at the same pace. Results are rounded to the nearest second.
The maths was checked against standard race conversions, for example a 3:00:00 marathon at 6:52 per mile (4:16 per km) and a 25:00 5K at 5:00 per km. Real races vary with course, weather and how you feel on the day, so treat the numbers as a guide rather than training or medical advice.
