48:00 10K: what it equals and how to train for it
Running a 10K in 48:00 means holding 4:48 per kilometre (7:43 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 | 23:08 | 4:38 | 7:27 |
| 10K | 48:00 | 4:48 | 7:43 |
| 15K | 1:13:55 | 4:56 | 7:56 |
| 10 miles | 1:19:41 | 4:57 | 7:58 |
| Half marathon | 1:46:25 | 5:03 | 8:07 |
| Marathon | 3:40:41 | 5:14 | 8:25 |
Training paces for this fitness
| Run | Per km | Per mile | What it is for |
|---|---|---|---|
| Easy | 5:38 to 6:29 | 9:04 to 10:25 | Most of your running: conversational, builds the base. |
| Marathon | 5:14 | 8:25 | Steady, controlled race-effort running. |
| Threshold | 4:54 | 7:53 | Comfortably hard: tempo runs and cruise intervals. |
| Interval | 4:31 | 7:16 | Hard repeats of 3 to 5 minutes with jog recoveries. |
| Repetition | 4:15 | 6:50 | 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.
