This calculation assumes the total time is spread evenly across the full distance. Stops, signals, GPS drift, hills, and treadmill calibration are not adjusted automatically.
What is the Running Pace Calculator?
The Running Pace Calculator finds your average pace from distance and total time. The core formula is average pace = total time ÷ distance, with results shown in min/mile and min/km.
It is focused on quick workout log checks rather than full race strategy. Use it to compare GPS app data, treadmill records, manual notes, or race splits when you know only distance and elapsed time.
When to use it
If you have distance and total time but not the average pace, this calculator converts the record into pace and speed immediately. The English version uses miles as the default while still showing kilometer pace for 5K and 10K training.
- Check whether 3.1 miles in 30 minutes is about a 9:41/mi pace
- Turn treadmill or manual notes into a pace for your training log
- Estimate 5K, 10K, half-marathon, and marathon times at the same pace
- Compare mile-based app records with kilometer-based race plans
- Use the 400 m lap equivalent for track workouts
Key features
Results update as soon as you change distance or time, so average pace, speed, and goal-distance times stay in sync. Quick examples cover common 5K, 10K, half-marathon, and marathon-style records.
- Large min/mile average pace result for US-style running logs
- Automatic min/km conversion for metric races and training plans
- Average speed and 400 m lap pace as supporting metrics
- Estimated 5K, 10K, half-marathon, and marathon times at the same pace
- Copy-ready result summary for training notes
How to use
Enter the distance, choose miles or kilometers, then enter the total time in hours, minutes, and seconds. The result panel updates the average pace and supporting metrics automatically.
- Enter the distance. For a 5K-style run, use about 3.1 miles or 5 km.
- Enter the total elapsed time in hours, minutes, and seconds.
- Review min/mile pace, min/km pace, average speed, and 400 m lap pace.
- Use Copy result if you want to paste the summary into a workout log.
Formula and interpretation
For min/mile pace, total time is converted to seconds and divided by distance in miles. For example, 3.1 miles in 30 minutes is 1,800 seconds ÷ 3.1 miles, or about 581 seconds per mile, which is 9:41/mi.
The result is an average across the whole distance. Real runs may include faster and slower segments, and apps may treat auto-pause, GPS correction, moving time, and elapsed time differently. Use this as a workout check and planning aid, not as an official timing result.
FAQ
What is the formula for pace from distance and time?
Average pace = total time ÷ distance. Convert total time to seconds or minutes, divide by miles or kilometers, then format the result as min/mile or min/km.
What pace is 3.1 miles in 30 minutes?
Thirty minutes over 3.1 miles is about 9:41 per mile. It is also roughly 6:01 per kilometer, depending on rounding.
Can I calculate min/km too?
Yes. Even when miles are the default, the calculator also shows kilometer pace. You can also switch the distance unit to km and use metric inputs directly.
How are pace and speed different?
Pace is time per mile or kilometer, while speed is distance per hour. Runners usually plan workouts by pace, while speed is useful for cross-checking treadmill or cycling-style data.
Why does my GPS app show a different pace?
GPS apps may use moving time, elapsed time, auto-pause, corrected distance, or treadmill calibration differently. This calculator uses only the distance and total time you enter.
