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
  1. 01Pace = 30 / 3.1 = 9.68 min/mile
  2. 02Pace per km = 9.68 / 1.609 = 6.01 min/km
  3. 03Speed = 60 / 9.68 = 6.2 mph
