Sub-3:15 marathon: VO2max 49
Running a sub-3:15 marathon takes a running VO2max (VDOT) of about 48.7 and an even pace of 4:37/km (7:26/mile).
Even-pace splits
| Distance | Split |
|---|---|
| 5 km | 23:06 |

Training paces for this goal
| Pace | Per km |
|---|---|
| Easy | 5:14–5:46 |
| Marathon | 4:37 |
| Threshold | 4:21 |
| Interval (VO2max) | 4:01 |
| Repetition | 3:46 |
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 (4:37/km).
Equivalent race times
| 5K | 10K | Half marathon | Marathon |
|---|---|---|---|
| 20:24 | 42:17 | 1:33:40 | 3:15:00 |
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-3:15 marathon?
About 48.7 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-3:15 marathon?
4:37 per km or 7:26 per mile, run evenly.
What 5K time matches a sub-3:15 marathon?
About 20:24 on the same VDOT model.
Is a sub-3:15 marathon good?
A VO2max of 49 is rated "excellent" for men in their 30s and "superior" for women in their 30s on Cooper Institute norms.
