Splits
Even pace versus a 1 % negative split. Both finish exactly on 4:15:00; aim to cross the line a little inside it.
| Point | Even pace | 1 % negative |
|---|---|---|
| 5 km | 30:13 | 30:22 |
| 10 km | 1:00:26 | 1:00:44 |
| 15 km | 1:30:39 | 1:31:06 |
| 20 km | 2:00:52 | 2:01:28 |
| Half | 2:07:30 | 2:08:08 |
| 25 km | 2:31:05 | 2:31:36 |
| 30 km | 3:01:18 | 3:01:40 |
| 35 km | 3:31:31 | 3:31:44 |
| 40 km | 4:01:44 | 4:01:48 |
| Finish | 4:15:00 | 4:15:00 |
Race times that match this goal
Equivalent performances from Riegel's formula. If you can run these, sub 4:15 is realistic with the right training.
Training paces for sub 4:15
| Run type | Pace /km | Zone | Typical session |
|---|---|---|---|
| Recovery | 7:31–8:26 | Zone 1 | Between hard days, 20–40 min |
| Easy and long runs | 6:47–7:31 | Zone 1–2 | Most of your weekly volume |
| Marathon pace | 6:00–6:06 | Zone 2–3 | Long-run segments of 8–20 km |
| Threshold | 5:29–5:41 | Zone 3–4 | 3 × 10 min or 20–30 min steady |
| Interval (VO2max) | 5:09–5:19 | Zone 4–5 | 5 × 1000 m, 3 min jog |
| Repetition | 4:55–5:01 | Zone 5 | 8 × 200–400 m, full recovery |
What it takes
Most runners who break 4:15 in the marathon build to about 45–65 km a week over 12–16 weeks, with long runs of 30–35 km. The key sessions are marathon-pace segments inside long runs and one threshold session a week.
A half marathon around 2:02:18 six to eight weeks before the race is a good checkpoint. If you are slower than 2:05:59, aim for sub 4:30 instead and adjust after your next test.
Weekly volumes are typical ranges, not requirements. Build up gradually and adjust to your own history.
Common questions
How fast is sub 4:15 marathon pace per mile?
9:43 per mile, or 6:02 per kilometre.
What half marathon time do I need for a sub 4:15 marathon?
Around 2:02:18 on Riegel's formula, assuming training that is specific to the marathon.
Should I run even splits?
Yes, or a very slight negative split. Starting faster than goal pace costs far more time late in the race than it gains early. Read how to pace a marathon for a simple plan.
