Sub 3:00 marathon pace
To run a marathon under 3:00:00 you need to average 4:15 per kilometre, or 6:51 per mile. Here are the splits, a pace band, the paces to train at and the fitness you need before race day.

Splits
Even pace versus a 1 % negative split. Both finish exactly on 3:00:00; aim to cross the line a little inside it.
| Point | Even pace | 1 % negative |
|---|---|---|
| 5 km | 21:20 | 21:26 |
| 10 km | 42:40 | 42:52 |
| 15 km | 1:03:59 | 1:04:19 |
| 20 km | 1:25:19 | 1:25:45 |
| Half | 1:30:00 | 1:30:27 |
| 25 km | 1:46:39 | 1:47:01 |
| 30 km | 2:07:59 | 2:08:14 |
| 35 km | 2:29:18 | 2:29:28 |
| 40 km | 2:50:38 | 2:50:41 |
| Finish | 3:00:00 | 3:00:00 |
Race times that match this goal
Equivalent performances from Riegel's formula. If you can run these, sub 3:00 is realistic with the right training.
Training paces for sub 3:00
| Run type | Pace /km | Zone | Typical session |
|---|---|---|---|
| Recovery | 5:25–6:04 | Zone 1 | Between hard days, 20–40 min |
| Easy and long runs | 4:53–5:25 | Zone 1–2 | Most of your weekly volume |
| Marathon pace | 4:13–4:19 | Zone 2–3 | Long-run segments of 8–20 km |
| Threshold | 3:57–4:05 | Zone 3–4 | 3 × 10 min or 20–30 min steady |
| Interval (VO2max) | 3:38–3:45 | Zone 4–5 | 5 × 1000 m, 3 min jog |
| Repetition | 3:28–3:33 | Zone 5 | 8 × 200–400 m, full recovery |
What it takes
Most runners who break 3:00 in the marathon build to about 80–110 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 1:26:20 six to eight weeks before the race is a good checkpoint. If you are slower than 1:28:55, aim for sub 3:15 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 3:00 marathon pace per mile?
6:51 per mile, or 4:15 per kilometre.
What half marathon time do I need for a sub 3:00 marathon?
Around 1:26:20 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.
