Average Speed & Running Pace Calculator | Hours, Minutes, Seconds
Calculate km/h, running pace per kilometer and estimated 5K/10K times from distance and hours, minutes or seconds. Supports total minutes, decimal distances, input checks and result copying.
Try the tool
Enter your details below. Results update instantly.
Enter distance and time to calculate speed and pace.
Minutes can be greater than 59, so you can enter 90 minutes without filling hours. Distance: 0.000001–100,000 km. Optional seconds support precise running records; total time is limited to 9,999 hours. Results are rounded to seconds; <0:01 means less than one second.
Average speed and running pace from distance and time
When you walk, run, cycle, or travel, it is useful to know how fast you actually moved.
This tool converts distance and time into average speed (km/h), pace per kilometer, total time, and even estimated 5K and 10K times. If you only know total minutes, you can enter 90 minutes directly without converting it to 1 hour 30 minutes first.
Key features
- Calculate average speed from distance and time
- Automatically show pace per kilometer
- Support total-minute entries greater than 59
- Explain missing distance, negative or fractional time values, and zero-duration inputs
- Estimate 5K and 10K times from the same speed
- Load an example, clear inputs, and copy valid results
- Useful for running, walking, cycling, and trip planning
How to use it
- Enter the travel distance in kilometers.
- Enter hours, minutes and optional seconds. For 1 hour 30 minutes, enter
1hour and30minutes. For 90 minutes, leave hours blank and enter90in minutes. You can also enter total seconds alone. - Check average speed and pace.
- Use the projected 5K and 10K times as quick references, then copy the valid results. To try the seconds input, load the 10 km / 52 min 30 sec running example; use Clear to start again.
Formula
- Average speed (km/h) = distance ÷ total time in hours
- Pace (min/km) = total time in minutes ÷ distance
- Estimated finish time = pace × target distance
For example, if you travel 10 km in 1 hour, your average speed is 10 km/h and your pace is 6:00 per km.
If you run 10 km in 52 minutes, the result is about 11.54 km/h with a 5:12/km pace. The 5K and 10K estimates are simple conversions from that same pace.
Input checks
- Distance is required and must be from 0.000001 to 100,000 km. Decimal distances such as 3.5 km and 42.195 km are supported.
- Hours, minutes and seconds must be non-negative whole numbers. Blank time fields count as zero.
- Minutes can be greater than 59, so
90minutes is valid. - Total time must be greater than 0 and no more than 9,999 hours. Zero duration or a duration above the limit shows an error.
- With all fields empty, results show
-and the tool prompts you to enter distance and time. Invalid inputs clear the results and disable copying; correct the highlighted fields to calculate again.

FAQ
Which value is more useful: km/h or min/km?
km/h is often easier for vehicles and general travel, while min/km is more intuitive for running and pace-based training.
Can I enter decimal distances?
Yes. Distances such as 3.5 km or 42.195 km work fine.
Does 90 minutes become 1 hour 30 minutes?
Yes. Minute values are treated as total minutes, so 90 minutes is calculated as 1 hour 30 minutes.
Are the estimated times official race predictions?
No. They are simple projections based on your entered average speed and should be used as rough references only.
Seconds and result precision
For 10 km in 52 minutes 30 seconds, average speed is about 11.43 km/h, pace is 5:15/km, and estimated 5K time is 26:15. Total minutes or total seconds alone also work.
Distance must be 0.000001–100,000 km; hours, minutes and seconds must be non-negative integers. Speed is rounded to two decimal places; pace and finish times to whole seconds. Very small speeds display as <0.01 km/h; times under one second display as <0:01. Seconds are preserved rather than first rounding the input to minutes.
Include stops for overall trip speed, or exclude them for moving speed. Calculations stay in your browser and are not saved. If automatic copy is blocked, select and copy the results manually.
Can I calculate a running record with seconds?
Yes. Combine hours, minutes and seconds, or enter total minutes or seconds alone. Blank time fields count as zero. Total duration must be greater than zero and no more than 9,999 hours.
