Pace Calculator - Calculator Soup

Find your running pace per mile, kilometer, yard or meter. Calculate the distance you can run in a given amount of time, time required to run a specific distance, or your running speed. Use this calculator to find average pace for running, biking, swimming or walking.

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

You can use this calculator to find your ideal pace to run an event like a marathon or half marathon.

Time, Distance, Pace, Speed formulas and relationships

• time = pace × distance time = pace time per unit distance × distance
• distance = time / pace distance = time / pace time per unit distance
• pace = time / distance pace time per unit distance = time / distance
• speed = distance / time speed distance per unit time = distance / time
