🏃 Speed / Pace Calculator
Calculate pace or speed from distance and time.
About this tool
Calculates running or cycling pace (time per unit distance) and speed from a distance and total time — useful for training plans, race predictions, or checking a workout after the fact.
Stacking up multiple training splits or interval times? The Time Duration Calculator can add them together first.
Worked example
Running 5 km in 25 minutes works out to a 5:00 min/km pace, or about 12 km/h — enter your own numbers to check against a race goal.
How to use it
- Enter the distance covered and select miles or kilometers.
- Enter the total time as hours and minutes.
- Press Calculate to see pace and speed.
Tips
- Pace (minutes per mile/km) is more useful for runners; speed (mph/kph) is more common for cycling.
- Use this to sanity-check a race goal — enter your target time and distance to see the pace you'll need to hold.
- For adding or comparing multiple split times, the Time Duration Calculator can help stack them up.
FAQ
What's the difference between pace and speed?
Pace is time per unit distance (minutes per mile); speed is distance per unit time (miles per hour) — they're inverses of each other.
Can I use this for cycling?
Yes, it works for any activity where you have a distance and a time — running, cycling, walking, or swimming.
Does this account for elevation or terrain?
No, it's a straight distance-and-time calculation without terrain adjustment.
