Running Pace Calculator
Running pace is how long it takes you to cover a unit of distance — usually expressed as minutes and seconds per mile. This calculator divides your total time by the distance you ran to give your pace in seconds per mile, which you can convert to the familiar mm:ss format. Knowing your pace helps you plan training runs, pace a race so you do not start too fast, and compare efforts over different distances. The result is simple arithmetic, so it is exact for the numbers you enter.

How to calculate
Enter the time you ran in minutes and the distance in miles. The calculator works out pace = (minutes × 60) ÷ miles in seconds per mile. For 50 minutes over 5 miles that is 600 seconds per mile. To read it as minutes and seconds, divide by 60: 600 ÷ 60 = 10, so 10:00 per mile. For race planning, find a target pace and multiply it by your race distance to estimate a finish time.
pace_seconds_per_mile = (time_minutes × 60) ÷ distance_miles. To display it, minutes = floor(pace ÷ 60) and seconds = pace − minutes × 60, giving the mm:ss form. Variables: time is the total elapsed minutes and distance is the miles covered. The result is seconds per mile; dividing by 60 converts it to minutes per mile.
Example calculation
Running 5 miles in 50 minutes is a pace of (50 × 60) ÷ 5 = 600 seconds per mile, which is 10:00 per mile (600 ÷ 60 = 10 minutes). To convert seconds per mile to the familiar mm:ss, divide by 60 for the minutes and take the remainder as the seconds.

Assumptions
- Pace is averaged over the whole run — it does not capture splits, hills, or how your pace changed during the effort.
- Distance is in miles and time in minutes; mixing units (e.g. kilometres into a mile field) gives a wrong pace.
- The calculation is exact arithmetic for the inputs, but a real run's GPS distance and timing carry their own small measurement errors.
Common mistakes
- Confusing pace with speed. Pace is time per distance (lower is faster); speed is distance per time (higher is faster) — they are inverses.
- Entering distance in kilometres while the field expects miles, which scales the pace incorrectly.
- Reading the seconds-per-mile figure as minutes. Divide by 60 first: 600 seconds per mile is 10:00, not 600 minutes.
Frequently asked questions
How do I calculate my running pace?
Divide your total time by the distance. For 50 minutes over 5 miles, pace is (50 × 60) ÷ 5 = 600 seconds per mile, which is 10:00 per mile.
How do I convert seconds per mile to minutes and seconds?
Divide the seconds by 60 for the minutes and take the remainder as the seconds. 600 ÷ 60 = 10 with no remainder, so 600 seconds per mile is exactly 10:00 per mile.
What is the difference between pace and speed?
Pace is time per distance (minutes per mile) and speed is distance per time (miles per hour). They are inverses: a faster runner has a lower pace number but a higher speed.
How do I use pace to plan a race?
Pick a target pace and multiply it by the race distance to estimate your finish time. Starting a little slower than goal pace and finishing strong is usually more effective than going out too fast.
