Sub-3 marathon: VO2max 54
Running a sub-3 marathon takes a running VO2max (VDOT) of about 53.5 and an even pace of 4:16/km (6:52/mile).
Even-pace splits
| Distance | Split |
|---|---|
| 5 km | 21:20 |
| 10 km | 42:40 |
| 15 km | 1:03:59 |
| 20 km | 1:25:19 |
| Half (21.1 km) | 1:30:00 |
| 25 km | 1:46:39 |
| 30 km | 2:07:59 |
| 35 km | 2:29:18 |
| 40 km | 2:50:38 |
| Marathon | 3:00:00 |
Training paces for this goal
| Pace | Per km |
|---|---|
| Easy | 4:51–5:20 |
| Marathon | 4:16 |
| Threshold | 4:01 |
| Interval (VO2max) | 3:43 |
| Repetition | 3:29 |
Use these for easy runs, tempo runs and VO2max intervals. A key session for this goal: Long runs of 28–32 km with 2–3 × 5 km at goal pace (4:16/km).
Equivalent race times
| 5K | 10K | Half marathon | Marathon |
|---|---|---|---|
| 18:48 | 38:59 | 1:26:16 | 3:00:00 |
If you can already run these, the goal is within reach once you are trained for the distance. Marathon equivalents are optimistic for most runners — endurance, fuelling and pacing matter as much as VO2max (see marathon training and VO2max).

Frequently asked questions
What VO2max do you need for a sub-3 marathon?
About 53.5 ml/kg/min of running VO2max (VDOT) if you are fully trained for the distance. Watch VO2max estimates often read a few points differently from VDOT.
What pace is a sub-3 marathon?
4:16 per km or 6:52 per mile, run evenly.
What 5K time matches a sub-3 marathon?
About 18:48 on the same VDOT model.
Is a sub-3 marathon good?
A VO2max of 54 is rated "superior" for men in their 30s and "superior" for women in their 30s on Cooper Institute norms.
