Training paces for this fitness
| Run | Per km | Per mile | What it is for |
|---|---|---|---|
| Easy | 7:31 to 8:35 | 12:05 to 13:50 | Most of your running: conversational, builds the base. |
| Marathon | 7:02 | 11:20 | Steady, controlled race-effort running. |
| Threshold | 6:34 | 10:34 | Comfortably hard: tempo runs and cruise intervals. |
| Interval | 6:03 | 9:45 | Hard repeats of 3 to 5 minutes with jog recoveries. |
| Repetition | 5:42 | 9:11 | 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.
