How to calculate running paceDivide your run time by your distanceIf you ran 3 miles in 30 minutes:
30 min ÷ 3 mi = 10 minutes per mile paceHow to calculate run distanceDivide your running time by your paceIf your pace is 8 minutes per mile and you ran for 32 minutes:
32 min ÷ 8 min per mi = 4 milesHow to calculate run timeMultiply your pace by your distanceIf 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 secondsHow to calculate running speedDivide your run distance by your run timeIf you ran 2.5 miles and you ran for 20 minutes:
