What is a good VO₂max for a runner?
The median adult in their 20s tests at about 48 mL/kg/min (men) or 38 (women), and the figure falls with age. Trained runners usually sit well above that, and far below elite values.
Published VO₂max norms tend to be quoted from elite cohorts, which makes them close to useless as a target for most runners. Peak values approach 85 mL/kg/min for men and 72 for women, but those are the extreme upper bound of human physiology at around age 25, not a benchmark. A recreational runner in the 40s can and does run marathons well.
A more useful frame: your VO₂max determines your aerobic ceiling, but your race times are set by how much of that ceiling you can sustain and how efficiently you convert oxygen into speed. Plenty of runners outperform others with higher VO₂max values because they hold a higher fraction of it and run more economically.
Age-adjust before you judge yourself. The decline is roughly 0.5–0.7% per year for active adults past their mid-thirties, so a 55-year-old and a 25-year-old with the same number are not equivalent athletes — the older one is considerably more remarkable. Age-grading a race result gives a fairer comparison than comparing raw physiology.
The practical takeaway is that VO₂max is a poor training target and a reasonable diagnostic. If it is low relative to your training history, aerobic volume is the lever. If it is high but your race times lag, look at threshold and economy instead.
Key numbers
| Elite ceiling, age 25 | ~85 (M) / ~72 (F) | mL/kg/min |
|---|---|---|
| Typical trained club runner | ~55–70 | mL/kg/min |
| Annual decline | 0.5–0.7% | active adults over ~35 |
Median VO₂max by age and sex (mL/kg/min)
| Age | Men | Women |
|---|---|---|
| 20–29 | 48.0 | 37.6 |
| 30–39 | 42.4 | 30.2 |
| 40–49 | 37.8 | 26.7 |
| 50–59 | 32.6 | 23.4 |
| 60–69 | 28.2 | 20.0 |
| 70–79 | 24.4 | 18.3 |
The 50th percentile from treadmill tests of apparently healthy US adults in the FRIEND registry (Kaminsky et al. 2015). Above the median for your age is above average; most people who run regularly are, often by a wide margin. These are general-population figures, not runner norms.

Frequently asked questions
What is a good VO₂max for a man?
Against the general population, anything above the median for your age is above average: about 48 mL/kg/min in your 20s, 42 in your 30s, 38 in your 40s and 33 in your 50s. Regular runners typically exceed those figures, and trained club runners often sit in the 50s and 60s.
What is a good VO₂max for a woman?
The general-population median is about 38 mL/kg/min in your 20s, 30 in your 30s, 27 in your 40s and 23 in your 50s, so a value above that is above average for your age. Women who train regularly commonly sit well above it; at the same training level values typically run below men's, largely because of differences in haemoglobin concentration and body composition.
Is my watch's VO₂max estimate accurate?
Treat it as a trend line rather than a measurement. Wrist-based estimates infer VO₂max from the relationship between pace and heart rate, so they inherit every error in your heart-rate data and in the assumed maximum. Changes over months are informative; the absolute number is not.
Do I need a high VO₂max to run a marathon?
No. Marathon performance is limited more by fuelling, threshold and durability than by aerobic ceiling for the overwhelming majority of finishers. Consistency in training does more for your finish time than chasing a number.
