Performance, Down to the Decimal

Sports statistics turn performance into comparable numbers across games, seasons, and even eras — a batting average or passer rating means the same thing whether it happened yesterday or a decade ago. These calculators cover scoring, pace, and performance math across sports.

How Pace Determines Finish Time

Marathon finish time by per-mile pace 8 minutes per mile: 3 hours 29 minutes. 9 minutes per mile: 3 hours 56 minutes. 10 minutes per mile: 4 hours 22 minutes. 3:29 8 min/mile 3:56 9 min/mile 4:22 10 min/mile
Marathon (26.2 mile) finish time at three steady per-mile paces. Calculated with the Running Pace Calculator.

A seemingly small 1-minute-per-mile pace difference adds up to roughly 26 minutes over a full marathon — which is exactly why serious runners train around a specific target pace rather than just "running comfortably." Plan your own target with the Running Pace Calculator.
