How to calculate running pace

  • Divide your run time by your distance
  • If you ran 3 miles in 30 minutes:  30 min ÷ 3 mi = 10 minutes per mile pace

How to calculate run distance

  • Divide your running time by your pace
  • If your pace is 8 minutes per mile and you ran for 32 minutes:  32 min ÷ 8 min per mi = 4 miles

How to calculate run time

  • Multiply your pace by your distance
  • If your pace is 9.5 minutes per mile and you ran 3 miles:  9.5 min per mi × 3 mi = 28.5 minutes = 28 minutes, 30 seconds

How to calculate running speed

  • Divide your run distance by your run time
  • If you ran 2.5 miles and you ran for 20 minutes: 2.5 mi ÷ 20 min = 0.125 miles per minute
