Example

A 10K in 50:00 is 8:03 per mile (5:00 per km, 7.46 mph). At that pace a half marathon takes 1:45:30.

Method and formula

Pace = time / distance. Conversions use 1 mile = 1.609344 km. Equivalent race times use the Riegel formula (T2 = T1 × (D2/D1)^1.06).

Limits

Splits assume an even pace; terrain, weather and pacing errors change real splits.

FAQ

How do I convert min/km to min/mile?

Multiply by 1.609. 5:00 per km is 8:03 per mile.

What is a good running pace?

It depends on distance and experience. Recreational runners often sit between 9 and 12 min/mile for easy runs; race pace is faster.
