Running Pace Calculator

Pace per kilometre, speed and finish-time estimates for 5K to marathon.

Pace9:02 /mile
Speed6.6 mph
5K at this pace28:04
10K at this pace56:07
Half marathon at this pace1:58:25
Marathon at this pace3:56:51

Per-mile splits at an even pace are simply your pace repeated each mile (mile 1 at 9:02, mile 2 at 18:04, and so on). The standard-distance times assume you hold exactly this pace — in real races, longer distances are run slower per mile, so treat the marathon figure as optimistic.
