How to Use the Pace Calculator
The relationship between pace, time, and distance means that any one of the three can be calculated when the other two are known. Choose the mode that matches the information you already have.
Find Pace
Use Find Pace when you know how far you ran and how long it took. Enter the distance, choose miles or kilometres, and enter the total time. The result shows your average minutes per kilometre, minutes per mile, km/h, mph, and equivalent finish times at that exact pace.
For example, running 5 kilometres in 25 minutes produces an average pace of 5:00 per kilometre. That converts to approximately 8:03 per mile and an average speed of 12 km/h.
Find Finish Time
Choose Find Finish Time when you know the distance and the pace you intend to maintain. This is useful when planning a race goal or estimating how long a training run will take.
For example, running a 10K at exactly 5:00 per kilometre produces a 50-minute finish time.
Find Distance
Use Find Distance when you know how long you will run and the pace you plan to maintain. A 45-minute run at 6:00 per kilometre covers 7.5 kilometres.
Race Splits
Race Splits converts a target finish time into an average pace and cumulative checkpoint times. Choose a standard distance or enter a custom distance, enter the finish time, and select kilometre, mile, or 5K splits.
Pace / Speed Converter
This mode converts a pace between minutes per kilometre and minutes per mile while also showing the equivalent speed in kilometres per hour and miles per hour. It is particularly useful when setting a treadmill that displays speed instead of pace.
What Is Running Pace?
Running pace describes the amount of time required to cover a fixed distance. Instead of saying that you ran at 12 kilometres per hour, you might say that you ran at a pace of 5 minutes per kilometre.
In countries where running distances are commonly measured in miles, pace is often written as minutes per mile. A runner might describe a workout as 8:00 per mile, meaning each mile takes approximately eight minutes at that average pace.
Pace and speed describe the same movement in different ways. A faster pace has a smaller time value because less time is required to cover each kilometre or mile.
How to Calculate Running Pace
The basic running pace formula is:
If you run 10 kilometres in 50 minutes:
50 minutes ÷ 10 kilometres = 5 minutes per kilometre.
Your average pace is therefore 5:00/km.
The same calculation works in miles. If you run 5 miles in 40 minutes:
40 ÷ 5 = 8 minutes per mile.
Your pace is 8:00/mi.
If you need to calculate clock durations before determining your pace, the Time Calculator can calculate elapsed time, minutes, hours, and time differences separately.
How to Calculate Finish Time From Pace
If pace and distance are known, multiply them together.
At 6 minutes per kilometre, a 10-kilometre run takes:
6 minutes × 10 = 60 minutes.
At 8 minutes per mile, a 10-mile run takes 80 minutes, or 1 hour 20 minutes.
How to Calculate Distance From Pace and Time
When time and pace are known, divide the total time by the pace.
If you run for 60 minutes at 6:00 per kilometre:
60 ÷ 6 = 10 kilometres.
Pace Per Mile
Pace per mile tells you how many minutes and seconds it takes to travel one mile. A 9:00 mile pace means each mile takes an average of nine minutes.
If you maintain a 9:00-per-mile pace for five miles, your finish time is 45 minutes. Maintaining the same average for 10 miles produces 1 hour 30 minutes.
The calculator always displays pace per mile even when you enter the original distance in kilometres.
Pace Per Kilometre
Pace per kilometre represents the time required to cover one kilometre. A 6:00/km pace means each kilometre takes six minutes on average.
At 6:00/km, 5 kilometres takes 30 minutes, 10 kilometres takes 60 minutes, and a half marathon would take approximately 2 hours 6 minutes 35 seconds if that exact average pace were maintained for the entire distance.
How to Convert Pace Per Kilometre to Pace Per Mile
One mile equals exactly 1.609344 kilometres. Because a mile is longer than a kilometre, the time per mile is longer than the time per kilometre at the same speed.
To convert a pace from seconds per kilometre to seconds per mile, multiply by 1.609344.
A 5:00/km pace is 300 seconds per kilometre:
300 × 1.609344 = 482.8032 seconds.
That is approximately 8 minutes 3 seconds per mile.
How to Convert Pace Per Mile to Pace Per Kilometre
Divide seconds per mile by 1.609344.
An 8:00 mile contains 480 seconds:
480 ÷ 1.609344 ≈ 298.26 seconds.
That is approximately 4:58 per kilometre.
Running Pace vs. Speed
Pace measures time per distance, while speed measures distance per time. They are inverse ways of describing how quickly you are moving.
A faster runner has a lower pace number but a higher speed number. For example, 6:00/km equals 10 km/h. A faster 5:00/km pace equals 12 km/h.
| Pace / km | Approx. Pace / mile | Speed km/h | Speed mph |
|---|---|---|---|
| 4:00 | 6:26 | 15.00 | 9.32 |
| 4:30 | 7:15 | 13.33 | 8.28 |
| 5:00 | 8:03 | 12.00 | 7.46 |
| 5:30 | 8:51 | 10.91 | 6.78 |
| 6:00 | 9:39 | 10.00 | 6.21 |
| 6:30 | 10:28 | 9.23 | 5.74 |
| 7:00 | 11:16 | 8.57 | 5.33 |
| 8:00 | 12:52 | 7.50 | 4.66 |

| 30:00 | 6:00 | 9:39 |
| 35:00 | 7:00 | 11:16 |
10K Pace Calculator
A 10K is 10 kilometres, approximately 6.214 miles. Because the distance is exactly 10 kilometres, target pace is particularly easy to calculate manually: divide the finish time in minutes by 10.
A 50-minute 10K requires a 5:00/km pace. A 60-minute 10K requires 6:00/km. A 45-minute target requires 4:30/km.
| 10K Time | Pace / km | Approx. Pace / mile |
|---|---|---|
| 40:00 | 4:00 | 6:26 |
| 45:00 | 4:30 | 7:15 |
| 50:00 | 5:00 | 8:03 |
| 55:00 | 5:30 | 8:51 |
| 1:00:00 | 6:00 | 9:39 |
| 1:10:00 | 7:00 | 11:16 |
Half Marathon Pace Calculator
A half marathon is 21.0975 kilometres, approximately 13.109 miles. Use Race Splits to enter a goal time and see the required average pace plus kilometre or mile checkpoints.
A 2-hour half marathon requires an average pace of approximately 5:41 per kilometre or 9:09 per mile.
A 1-hour-45-minute half marathon requires approximately 4:59 per kilometre. A 2-hour-30-minute finish requires approximately 7:07 per kilometre.
| Half Marathon | Approx. / km | Approx. / mile |

| 1:30:00 | 4:16 | 6:52 |
| 1:45:00 | 4:59 | 8:01 |
| 2:00:00 | 5:41 | 9:09 |
| 2:15:00 | 6:24 | 10:18 |
| 2:30:00 | 7:07 | 11:27 |
Marathon Pace Calculator
The marathon distance is 42.195 kilometres, equivalent to 26 miles and 385 yards. Enter 42.195 km or select the Marathon preset, then enter your target finish time.
A 4-hour marathon requires an average pace of approximately 5:41 per kilometre or 9:09 per mile. A 3-hour-30-minute marathon requires approximately 4:59/km, while a 5-hour marathon requires approximately 7:07/km.
| Marathon Time | Approx. / km | Approx. / mile |
|---|---|---|
| 3:00:00 | 4:16 | 6:52 |
| 3:30:00 | 4:59 | 8:01 |

| 4:30:00 | 6:24 | 10:18 |
| 5:00:00 | 7:07 | 11:27 |
Race Split Calculator
A split is the elapsed time at a particular point during a run or race. Splits help runners compare their actual progress with a target average pace.
For example, a runner targeting a 50-minute 10K at an even 5:00/km pace would reach the checkpoints at approximately:
- 1 km — 5:00
- 2 km — 10:00
- 3 km — 15:00
- 4 km — 20:00
- 5 km — 25:00
- 6 km — 30:00
- 7 km — 35:00
- 8 km — 40:00
- 9 km — 45:00
- 10 km — 50:00
The calculator creates these cumulative checkpoints automatically. They are mathematical even-pace splits, not a requirement that every section of a real race be run at exactly the same speed.
Even Splits
An even split strategy means maintaining approximately the same average pace through the full event. If your target is 5:00/km, an idealized even-split calculation places every kilometre at approximately five minutes.
Real-world pace will often fluctuate. Hills, sharp turns, aid stations, wind, surface changes, crowds, and GPS error can make individual splits faster or slower even when the overall average remains close to the goal.
Negative Splits
A negative split generally means completing the second part of a run or race faster than the first. The average pace needed for the complete race does not change, but the runner distributes the effort differently across the distance.
This calculator intentionally shows neutral even splits rather than claiming one pacing strategy is best for every athlete or course.
Positive Splits
A positive split occurs when the second portion takes longer than the first. This can happen intentionally or because of fatigue, hills, weather, fueling issues, or starting faster than can be sustained.
Treadmill Pace Calculator
Many treadmills display speed rather than minutes per kilometre or mile. Use Pace / Speed mode to convert your outdoor target pace into the corresponding treadmill speed.
For example:
- 4:00/km = 15.0 km/h
- 5:00/km = 12.0 km/h
- 6:00/km = 10.0 km/h
- 7:00/km ≈ 8.57 km/h
- 8:00/km = 7.5 km/h
Treadmill belt speed does not guarantee that indoor effort will feel identical to outdoor running. Cooling, incline, treadmill calibration, running mechanics, and environmental conditions can all affect perceived effort.
Running Pace Chart
This quick chart shows common kilometre paces and the time those paces produce over 5K and 10K when maintained evenly.
| Pace / km | Approx. / mile | 5K Time | 10K Time |
|---|---|---|---|
| 4:00 | 6:26 | 20:00 | 40:00 |
| 4:30 | 7:15 | 22:30 | 45:00 |
| 5:00 | 8:03 | 25:00 | 50:00 |
| 5:30 | 8:51 | 27:30 | 55:00 |
| 6:00 | 9:39 | 30:00 | 1:00:00 |
| 6:30 | 10:28 | 32:30 | 1:05:00 |
| 7:00 | 11:16 | 35:00 | 1:10:00 |
| 7:30 | 12:04 | 37:30 | 1:15:00 |
| 8:00 | 12:52 | 40:00 | 1:20:00 |
Walking Pace Calculator
The same formulas work for walking. Enter your walking distance and total time into Find Pace to calculate minutes per kilometre, minutes per mile, and average speed.
For example, walking 5 kilometres in one hour gives an average pace of 12:00/km and an average speed of 5 km/h.
Running Pace and Distance
Pace can also help estimate how far a time-based workout will take you. A runner maintaining 5:00/km for 30 minutes covers approximately 6 kilometres. At 6:00/km, the same 30-minute run covers approximately 5 kilometres.
If you need geographic distance between two actual places rather than the distance covered at a running pace, use the Distance Calculator.
Average Pace vs. Instant Pace
This calculator determines average pace across the entire entered distance. GPS watches and running apps may also display instant pace, lap pace, moving pace, grade-adjusted pace, or other metrics.
Instant pace describes an estimate of your speed at a particular moment and can fluctuate substantially. Average pace uses the complete distance and time, making it more stable for comparing an overall run or race.
Moving Time vs. Elapsed Time
Your calculated pace changes depending on which time you use. Elapsed time includes the complete period from start to finish, including stops. Moving time generally excludes periods when the tracking device considers you stopped.
For a race, official finish time is typically based on elapsed race timing rather than automatically removing every moment you slowed or stopped.
Why GPS Pace May Differ From a Calculator
A GPS device estimates distance from recorded positions. Trees, tall buildings, tunnels, curves, weak satellite reception, recording intervals, and smoothing algorithms can affect the measured route.
If a race is officially measured as 10 kilometres but your watch records 10.12 kilometres, pace calculated from the watch distance can differ from pace calculated using the official course distance.
Race Pace Is an Average
A target pace such as 5:00/km does not mean every kilometre must be exactly 5:00. A 4:55 kilometre followed by a 5:05 kilometre averages 5:00 across those two kilometres.
This matters on courses with elevation changes. Uphill sections may naturally be slower while downhill or flat sections may be faster.
Equivalent Race Times Are Not Predictions
The calculator displays what common race distances would take if you maintained exactly the same mathematical pace. These are useful comparisons, but they do not predict what you are physically capable of running.
For example, a runner who can run 5K at 5:00/km can mathematically cover a marathon in approximately 3:30:59 at the same pace. That does not mean the runner currently has the endurance or training required to hold 5:00/km for a marathon.
Factors That Affect Running Pace
- Distance: A pace that is sustainable for 5K may not be sustainable for a marathon.
- Elevation: Hills can substantially change kilometre or mile splits.
- Weather: Heat, cold, wind, humidity, rain, and snow may affect performance.
- Surface: Track, road, grass, gravel, mud, sand, and trails can produce different speeds.
- Fitness: Training history and current conditioning influence sustainable pace.
- Fatigue: Pace may slow as a long race or training session progresses.
- Fuel and hydration: Longer efforts may be affected by nutrition and fluid intake.
- Congestion: Crowded starting areas and narrow courses can affect early splits.
- Stops: Traffic lights, aid stations, bathroom stops, and rest breaks can alter elapsed pace.
Pace Calculator for Training
A pace calculator is useful for planning workout logistics even when you are not racing. If your training plan calls for a 40-minute run and you know your approximate pace, Find Distance can estimate the route length you need.
If you already know the route distance, Find Finish Time estimates how long the workout will take at a selected pace.
For calorie and daily energy estimates outside the pace calculation itself, the Calorie Calculator is available separately.
Common Running Pace Examples
Example 1: 5K in 25 Minutes
25 minutes ÷ 5 kilometres = 5 minutes per kilometre. The average pace is 5:00/km, approximately 8:03/mile.
Example 2: 10K in 60 Minutes
60 ÷ 10 = 6 minutes per kilometre. The pace is 6:00/km.
Example 3: 3 Miles in 30 Minutes
30 ÷ 3 = 10 minutes per mile. The pace is 10:00/mi, approximately 6:13/km.
Example 4: 45 Minutes at 5:00/km
45 ÷ 5 = 9 kilometres. At an even 5:00/km pace, a 45-minute run covers approximately 9 km.
Example 5: 10 Miles at 9:00/mile
9 minutes × 10 miles = 90 minutes, or 1 hour 30 minutes.
