Sub-25 5K: VO2max 38
Running a sub-25 5k takes a running VO2max (VDOT) of about 38.3 and an even pace of 5:00/km (8:03/mile).
Even-pace splits
| Distance | Split |
|---|---|
| 1 km | 5:00 |
| 2 km | 10:00 |
| 3 km | 15:00 |
| 4 km | 20:00 |
| 5K | 25:00 |
Training paces for this goal
| Pace | Per km |
|---|---|
| Easy | 6:19–6:57 |
| Marathon | 5:38 |
| Threshold | 5:16 |
| Interval (VO2max) | 4:53 |
| Repetition | 4:34 |
Use these for easy runs, tempo runs and VO2max intervals. A key session for this goal: 5–6 × 1,000 m at interval pace (4:53/km), 2–3 min jog.
Equivalent race times
| 5K | 10K | Half marathon | Marathon |
|---|---|---|---|
| 25:00 | 51:53 | 1:55:04 | 3:57:55 |
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-25 5k?
About 38.3 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-25 5k?
5:00 per km or 8:03 per mile, run evenly.
What 10K time matches a sub-25 5k?
About 51:53 on the same VDOT model.
Is a sub-25 5k good?
A VO2max of 38 is rated "poor" for men in their 30s and "good" for women in their 30s on Cooper Institute norms.
