How It Works
Running Pace Formula
Pace (min/mile) = Total Time (min) / Distance (miles)
Speed (mph) = 60 / Pace
To convert to pace per km, divide pace per mile by 1.609.
Worked Example
A 5K (3.1 miles) run in 30 minutes.
time_minutes = 30distance_miles = 3.1
- 01Pace = 30 / 3.1 = 9.68 min/mile
- 02Pace per km = 9.68 / 1.609 = 6.01 min/km
- 03Speed = 60 / 9.68 = 6.2 mph
