38:00 5K: what it equals and how to train for it
Running a 5K in 38:00 means holding 7:36 per kilometre (12:14 per mile). Here is what that fitness is worth at other distances, and the paces to train at.
Equal race times
Predictions from an equal-effort model: the time you could run at each distance with the same fitness and the right training. Longer distances need specific endurance work.
| Distance | Time | Pace per km | Pace per mile |
|---|---|---|---|
| 5K | 38:00 | 7:36 | 12:14 |
| 10K | 1:19:11 | 7:55 | 12:45 |
| 15K | 2:01:53 | 8:08 | 13:05 |
| 10 miles | 2:11:18 | 8:10 | 13:08 |
| Half marathon | 2:54:30 | 8:16 | 13:19 |
| Marathon | 5:55:01 | 8:25 | 13:32 |
Training paces for this fitness
| Run | Per km | Per mile | What it is for |
|---|---|---|---|
| Easy | 8:56 to 10:10 | 14:23 to 16:22 | Most of your running: conversational, builds the base. |
| Marathon | 8:25 | 13:32 | Steady, controlled race-effort running. |
| Threshold | 7:51 | 12:37 | Comfortably hard: tempo runs and cruise intervals. |
| Interval | 7:15 | 11:40 | Hard repeats of 3 to 5 minutes with jog recoveries. |
| Repetition | 6:51 | 11:01 | Short, fast repeats with full recovery, for speed and form. |
How to use these numbers
- Run most of your weekly distance at the easy pace. If you can only speak in short sentences, slow down.
- Keep threshold and interval work to a small share of the week, and add it gradually.
- Hot, hilly or windy? Judge hard sessions by effort, not pace.
- Re-check your numbers after a new race or a hard time trial: fitness changes, and so should your paces.
