How to Use This Calculator

Choose your calculation mode

"Find Pace": enter distance + time → get your pace per mile/km. "Find Time": enter distance + pace → get total finish time. "Find Distance": enter time + pace → get how far you'd go at that pace.

Entering time as HH:MM:SS

Use separate fields for hours, minutes, and seconds. For a 25-minute run: hours=0, minutes=25, seconds=0. For a 2-hour marathon finish: hours=2, minutes=0, seconds=0.

Converting between miles and km pace

The calculator automatically shows your equivalent pace in the other unit. A 8:00/mile pace equals 4:58/km. A 5:00/km pace equals 8:03/mile. Common race paces: 5K PR pace, 10K pace, half marathon pace are typically 10–30 sec/mile faster than marathon pace.
