3:00:00 marathon: what it equals and how to train for it
Running a marathon in 3:00:00 means holding 4:16 per kilometre (6:52 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 | 18:48 | 3:46 | 6:03 |
| 10K | 38:59 | 3:54 | 6:16 |
| 15K | 59:55 | 4:00 | 6:26 |
| 10 miles | 1:04:36 | 4:01 | 6:28 |
| Half marathon | 1:26:16 | 4:05 | 6:35 |
| Marathon | 3:00:00 | 4:16 | 6:52 |
Training paces for this fitness
| Run | Per km | Per mile | What it is for |
|---|---|---|---|
| Easy | 4:38 to 5:20 | 7:27 to 8:36 | Most of your running: conversational, builds the base. |
| Marathon | 4:16 | 6:52 | Steady, controlled race-effort running. |
| Threshold | 4:01 | 6:29 | Comfortably hard: tempo runs and cruise intervals. |
| Interval | 3:42 | 5:58 | Hard repeats of 3 to 5 minutes with jog recoveries. |
| Repetition | 3:29 | 5:37 | 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.
