Running Pace Calculator
Pace is time per distance: time divided by distance. Speed is distance divided by time.
One mile is exactly 1,609.344 metres. Half marathon and marathon are exactly 21.0975 km and 42.195 km.
Even splits keep one pace. Negative splits make the second half faster; positive splits make it slower. Finish time remains unchanged.
Displayed times are rounded; calculations always use unrounded seconds.
