| Level | VO2max | 5 km | 10 km | Half marathon |
|---|---|---|---|---|
| Average | 43.6 | 22:24 | 46:28 | 1:43:00 |
| Good | 45.4 | 21:39 | 44:53 | 1:39:29 |

A man with a VO2max of 51.1 (top 20% for men aged 20–29) has a fitness age of about 18; at 41.7 it is about 54. Check yours with the fitness age calculator.
How to move up a level
Most people gain several ml/kg/min within 8–12 weeks of consistent training: mostly easy aerobic work plus one interval session a week, such as the Norwegian 4×4. See how to improve your VO2max and, after 40, VO2max and ageing.
