Key Formulas
Formula
Example
Pace = Time ÷ Distance
30 min ÷ 3 mi = 10 min/mi
Distance = Time ÷ Pace
32 min ÷ 8 min/mi = 4 mi
Time = Pace × Distance
9.5 min/mi × 3 mi = 28.5 min
Speed = Distance ÷ Time
2.5 mi ÷ 20 min = 0.125 mi/min

Frequently Asked Questions
What is a running pace calculator?
A tool to compute pace, time, or distance by providing two of the three variables.
How to calculate running pace?
Divide run time by distance (e.g., 30 min ÷ 3 mi = 10 min/mi).
How to calculate run distance?
Divide running time by pace (e.g., 32 min ÷ 8 min/mi = 4 mi).
How to calculate run time?
Multiply pace by distance (e.g., 9.5 min/mi × 3 mi = 28.5 min).
How to calculate running speed?
Divide distance by time (e.g., 2.5 mi ÷ 20 min = 0.125 mi/min).
Can I switch units?
Yes—select meters, kilometers, miles, yards, feet, half or full marathon.
