Pace Calculator
A running pace calculator converts a distance and total time into pace (minutes and seconds per kilometer) and average speed — the standard way runners track and compare effort across different distances. Race times scale roughly with pace multiplied by distance, so a runner’s 5K pace is typically a little faster than their marathon pace even at the same effort level, since fatigue and pacing strategy change how sustainable a given pace is as distance increases.

How it works
- Enter your distance in kilometers.
- Enter your total time in minutes.
- Read your pace (min:sec per km) and average speed.
Formula pace = total time ÷ distance; speed = distance ÷ total time
Frequently asked questions
Does this work for miles instead of kilometers?
Enter your distance and time as measured — the pace label always reads "per km" for this tool, so convert miles to km first (or use the unit converter) if you measured in miles.
Can I use this for cycling or swimming?
The math (time ÷ distance) works for any steady-pace activity, though "pace" conventions differ by sport (cycling is usually reported as speed, swimming often as pace per 100m).
How do I use pace to plan a race?
Multiply your target pace by the race distance to estimate finish time, or work backward from a goal finish time to find the pace you need to hold.
Does this account for elevation or terrain?
No — it is a simple average from total distance and time, not an effort-adjusted pace.
What’s a good pace for a beginner runner?
There’s no universal “good” pace — it depends on fitness level and goals. Many beginners run an easy pace around 6:30-7:30 min/km (10-12 min/mile) and build speed with consistent training, so treat your own recent pace as the baseline to beat rather than a fixed target.
