How pace is calculated
Pace = Time ÷ Distance Speed = Distance ÷ Time
Example: a 5K in 27:30 is a pace of 5:30 per km, or 8:51 per mile, which is 6.78 mph.
The finish-time table assumes you hold exactly the same pace. Most runners slow down over longer distances, so expect real marathon and half-marathon times to be somewhat slower than an even-pace projection from a 5K.

Finish times at an even pace per mile:
| Per mile | Per km | 5K | 10K | Half marathon | Marathon |
|---|---|---|---|---|---|
| 6:00 | 3:44 | 18:38 | 37:17 | 1:18:39 | 2:37:19 |
| 7:00 | 4:21 | 21:45 | 43:30 | 1:31:46 | 3:03:32 |
| 8:00 | 4:58 | 24:51 | 49:43 | 1:44:53 | 3:29:45 |
| 9:00 | 5:36 | 27:58 | 55:55 | 1:57:59 | 3:55:58 |
| 10:00 | 6:13 | 31:04 | 1:02:08 | 2:11:06 | 4:22:11 |
| 11:00 | 6:50 | 34:11 | 1:08:21 | 2:24:12 | 4:48:24 |
| 12:00 | 7:27 | 37:17 | 1:14:34 | 2:37:19 | 5:14:38 |
