Calculate average pace per mile or kilometer, estimated finish time, distance, and speed using an activity’s recorded time and distance in your preferred measurement units.
Pace = Total time ÷ Distance
Speed = Distance ÷ Total timeThe result is based on the entered workload, time, distance, repetitions, body weight or heart-rate assumptions. Device accuracy, terrain, temperature, technique, fitness level and recovery can cause real performance to differ.
The Pace Calculator estimates how long it takes to cover each mile or kilometer using your total distance and elapsed time. It can also calculate total time from a target pace or estimate distance from pace and duration, depending on the available mode. Results may include pace per mile, pace per kilometer, and average speed. These estimates are useful for planning and reviewing running, walking, hiking, cycling, and similar activities. However, average pace does not measure fitness, effort, race readiness, or health status by itself.
Select the calculation that matches the information you already know. The three common options are calculating pace, total time, or distance.
Use the actual elapsed time if you want an overall pace that includes stops. Use moving time if you want to evaluate only the time spent actively running, walking, or cycling. Do not combine moving time with a distance measurement that includes sections completed during excluded time.
Enter seconds whenever possible. Even a small time difference can affect the displayed pace, particularly over short distances. Confirm that the distance and pace units match before interpreting the result.
The calculator divides total elapsed time by total distance to determine the average amount of time required to cover one unit of distance. For example, dividing minutes by miles produces minutes per mile.
If time is the unknown value, the calculator multiplies pace by distance. If distance is unknown, it divides total time by pace. Unit conversions may also be applied so that a result entered in kilometers can be displayed per mile, or vice versa.
Pace and speed describe the same activity in different ways. Pace expresses time per unit of distance, while speed expresses distance per unit of time. A lower running pace, such as 8:00 per mile instead of 9:00 per mile, represents faster movement. A higher speed represents faster movement.
The standard pace formula is:
Pace = Total Time ÷ Distance
Where:
The related formulas are:
Total Time = Pace × Distance
Distance = Total Time ÷ Pace
Average speed can be calculated as:
Average Speed = Distance ÷ Total Time
Time must be expressed consistently before performing the calculation. For example, 42 minutes and 30 seconds equals 42.5 minutes because 30 seconds is one-half of a minute.
One mile is approximately 1.609 kilometers. To convert a minutes-per-kilometer pace to minutes per mile, multiply the pace by approximately 1.609. To convert minutes per mile to minutes per kilometer, divide by approximately 1.609.
Because pace is formatted as minutes and seconds rather than a decimal, convert the decimal portion of a minute into seconds by multiplying it by 60. For example, 7.5 minutes equals 7 minutes and 30 seconds, not 7 minutes and 50 seconds.
Suppose a runner completes 10 kilometers in 50 minutes.
Pace per kilometer = 50 minutes ÷ 10 kilometers = 5 minutes per kilometer
The runner’s average pace is therefore 5:00 per kilometer.
Ten kilometers is approximately 6.214 miles. The corresponding pace per mile is:
50 minutes ÷ 6.214 miles = approximately 8.047 minutes per mile
The decimal portion is converted to seconds:
0.047 × 60 = approximately 2.8 seconds
The equivalent pace is approximately 8:03 per mile. Average speed for the same activity is 12 kilometers per hour, or approximately 7.46 miles per hour.
Your result represents the average pace across the entire entered distance and time. It does not show how consistently that pace was maintained. A runner could alternate between fast and slow segments and still produce the same average as someone moving at a steady pace.
| Result | Meaning |
|---|---|
| Pace per mile | Average minutes and seconds required to cover one mile |
| Pace per kilometer | Average minutes and seconds required to cover one kilometer |
| Estimated time | Projected duration based on the entered distance and pace |
| Estimated distance | Projected distance based on the entered duration and pace |
| Average speed | Distance covered per hour or another selected time unit |
Compare results only when the underlying conditions are reasonably similar. A pace recorded on a flat road may not be directly comparable with one recorded on a steep trail, treadmill, crowded route, or course with frequent stops.
A predicted finish time assumes that the entered pace can be sustained across the full distance. This assumption becomes less reliable when projecting a short-distance pace over a much longer event. Fatigue, fueling, hydration, weather, terrain, and pacing strategy can change actual performance.
The Pace Calculator provides a mathematical average or projection. It cannot evaluate cardiovascular fitness, training status, running efficiency, injury risk, hydration, recovery, or whether a particular pace is medically appropriate.
The calculation generally assumes a constant pace. Actual movement usually includes acceleration, slowing, hills, turns, fatigue, and environmental changes. Estimated completion times may therefore differ from real results, especially when the target distance is substantially longer than the distance used to establish the pace.
GPS watches, phones, treadmills, and mapped routes may produce different distance measurements. The calculator cannot correct inaccurate source data or determine which device measurement is most reliable.
Use the result as an informational planning estimate, not as a diagnosis or proof of fitness. If exercise causes chest pain, fainting, unusual shortness of breath, or other serious symptoms, stop the activity and seek appropriate medical assistance. People with medical concerns should obtain personalized exercise guidance from a qualified healthcare professional.
Divide your total running time by the distance covered. If you run 5 miles in 45 minutes, your average pace is 9 minutes per mile.
Pace measures the time required to cover a unit of distance, such as minutes per mile. Speed measures the distance covered during a unit of time, such as miles per hour. A lower pace and a higher speed both indicate faster movement.
Use moving time to examine pace while actively moving. Use elapsed time when stops, breaks, and delays should be included in the overall result. Race finish times normally reflect total elapsed time under the event’s timing rules.
Divide the minutes-per-mile value by approximately 1.609. Convert any decimal fraction of a minute to seconds by multiplying it by 60.
It can estimate finish time by multiplying target pace by race distance. The estimate assumes that the same pace is maintained throughout the event, so actual results may vary because of fatigue, terrain, weather, stops, and race strategy.
Treadmill calibration, belt speed, incline, wind resistance, terrain, GPS accuracy, and movement patterns can create differences. Results from the two settings are most useful when interpreted in their original context.
Calculate using a recent, representative effort rather than a personal best from a different condition. Recalculate when distance, duration, load or body weight changes materially.
Pace may be displayed in minutes per mile, minutes per kilometer, miles per hour, or kilometers per hour. Converting the result makes it easier to compare workouts, treadmill settings, training plans, and event distances that use different measurement systems.
| Pace per Mile | Pace per Kilometer | Speed (mph) | Speed (km/h) |
|---|---|---|---|
| 6:00 | 3:44 | 10.00 | 16.09 |
| 7:00 | 4:21 | 8.57 | 13.79 |
| 8:00 | 4:58 | 7.50 | 12.07 |
| 9:00 | 5:36 | 6.67 | 10.73 |
| 10:00 | 6:13 | 6.00 | 9.66 |
| 12:00 | 7:27 | 5.00 | 8.05 |
| 15:00 | 9:19 | 4.00 | 6.44 |
| 20:00 | 12:26 | 3.00 | 4.83 |
Values are rounded, so manually calculated results may differ by a second or a small fraction of a speed unit.
Select the correct distance before calculating pace or projected time. Event names do not always represent whole-mile distances, so replacing an official race distance with a rounded value can produce an inaccurate estimate.
| Distance | Miles | Kilometers |
|---|---|---|
| 1 kilometer | 0.621 miles | 1 kilometer |
| 1 mile | 1 mile | 1.609 kilometers |
| 5K | 3.107 miles | 5 kilometers |
| 10K | 6.214 miles | 10 kilometers |
| Half marathon | 13.109 miles | 21.098 kilometers |
| Marathon | 26.219 miles | 42.195 kilometers |
The following estimates assume the same average pace is maintained for the entire distance. They do not account for stops, elevation changes, fatigue, weather, congestion, or differences between measured course distance and device-recorded distance.
| Pace per Mile | 5K Time | 10K Time | Half-Marathon Time | Marathon Time |
|---|---|---|---|---|
| 7:00 | 21:45 | 43:30 | 1:31:46 | 3:03:32 |
| 8:00 | 24:51 | 49:43 | 1:44:52 | 3:29:45 |
| 9:00 | 27:58 | 55:55 | 1:58:00 | 3:55:58 |
| 10:00 | 31:04 | 1:02:08 | 2:11:06 | 4:22:11 |
| 12:00 | 37:17 | 1:14:34 | 2:37:18 | 5:14:37 |
| 15:00 | 46:36 | 1:33:12 | 3:16:38 | 6:33:17 |
A split is the elapsed time recorded at a selected point in an activity. To estimate even splits, multiply the target pace by the number of miles or kilometers completed.
For example, a target pace of 8:30 per mile produces the following cumulative split estimates:
| Distance Completed | Estimated Elapsed Time |
|---|---|
| 1 mile | 8:30 |
| 2 miles | 17:00 |
| 3 miles | 25:30 |
| 4 miles | 34:00 |
| 5 miles | 42:30 |
Actual splits may vary even when the overall average matches the target. A faster second half is commonly described as a negative split, while a slower second half is a positive split. These descriptions show how pace changed during the activity; they do not determine whether the effort was appropriate for an individual.
A calculated pace can help with practical planning when its assumptions are understood. Common uses include:
For a more realistic projection, use a recent pace recorded over a reasonably similar distance, surface, elevation profile, and activity type. A short sprint pace should not be treated as a reliable long-distance pace.
| Measurement | What It Includes | Useful For |
|---|---|---|
| Elapsed pace | All time from start to finish, including stops and breaks | Estimating total trip or event duration |
| Moving pace | Only the time classified as active movement | Reviewing pace while actively running, walking, or cycling |
Neither measurement is universally better. Choose the value that answers your specific question and use the same method when comparing activities. Device algorithms may define movement differently, so moving pace can vary between apps or trackers even when they use the same recorded route.
