Average Mile Time by Age: What the Sourced Standards Say, and Why a True Average Does Not Exist

Short answer: there is no measured population-wide average mile time, because nobody has timed a representative sample of adults over a mile. The best sourced stand-ins are military run standards. The US Navy's minimum passing pace on its 1.5-mile test works out to 9:00 per mile for men aged 20–24 and 10:20 for women, easing to 11:10 and 11:40 at 50–54. The Army's two-mile minimum is about 9:53 per mile for men and 11:23 for women at 22–26. So a healthy adult who can cover a mile in roughly 9 to 12 minutes is meeting a standard the services consider acceptable for their age. Top scores sit near 6 to 8 minutes. Performance holds until about 35, then fades slowly until the fifties.

Everything below states where each number comes from, and what kind of people it describes.

Why the usual "average mile time" tables have no source

Search for the average mile time and the same grid appears on dozens of sites: neat rows by age, columns for beginner, intermediate and elite, times to the second. Follow the citations and they lead to each other, or to a commercial app's user logs, or nowhere. To publish a real average, someone would have to recruit a random sample of adults, including the ones who never run and the ones who cannot, and time all of them over a mile. No such dataset could be found for this article.

What does get recorded falls into four groups, and none of them is the general public:

This article uses the first and the fourth, because they are published by named bodies, split by age and sex, and can be checked. A standard is a different kind of number from an average: it says what an organisation has decided is good enough, not what people typically do.

Mile pace by age for men: US Navy standards

The Navy's Physical Readiness Test includes a 1.5-mile run on a flat, solid track or outdoor course, with any combination of running and walking allowed. The December 2025 guide publishes times for eleven age bands. The table below takes three of its scoring levels and divides each 1.5-mile time by 1.5 to give pace per mile. The guide calls Probationary the lowest passing category.

Source: US Navy, Guide 5A, Physical Readiness Test, December 2025 (altitudes below 5,000 feet). Per-mile pace is calculated.

Read the right-hand column as a floor. The middle column, "Good Low", is the closest thing in the table to an ordinary fit adult: 8:00 per mile in the early twenties, just under 10:00 in the mid-forties, about 11:30 in the early sixties.

Mile pace by age for women: US Navy standards

Source: US Navy, Guide 5A, Physical Readiness Test, December 2025 (altitudes below 5,000 feet). Per-mile pace is calculated.

The gap between the sexes at the passing level is a little over a minute per mile in the twenties (9:00 against 10:20) and narrows to half a minute by the early fifties (11:10 against 11:40). In both tables the slowdown between 20 and 54 is gentle, then steps down sharply at 55.

The Army and Air Force two-mile standards

The Army Fitness Test became the Army's test of record on 1 June 2025 and includes a two-mile run, which the Army says can be done on an indoor or outdoor track or an improved surface such as a road. The scoring scales give times for 100 points and for 60 points, the minimum per event, in ten age groups. Halving each time gives pace per mile.

Source: US Army, AFT Scoring Scales, effective 1 June 2025. Per-mile pace is calculated, with half-seconds rounded up.

The women's 100-point time for 17–21 (16:00) is slower than for 22–26 (15:30); that is how the Army's scale reads, not a misprint here.

The Air Force announced in September 2025 that its assessment would include a two-mile run from 1 March 2026. The scoring charts published at that time use the Army's figures for the under-30 bands: 13:25 for maximum points and 19:45 as the slowest scoring time for men, 15:30 and 22:45 for women. Identical thresholds in two services are a reminder that these numbers are policy decisions, not independent measurements of how fast people run.

The Army and Navy floors are close. For a man in his early twenties the Navy asks for 9:00 per mile over 1.5 miles and the Army for about 9:53 over two. For a woman of the same age it is 10:20 and 11:23.

What these numbers do and do not tell you about one mile

Three adjustments are needed before comparing a single timed mile with the tables.

The pace is from a longer test. A person can hold a faster pace for one mile than for 1.5 or two. The per-mile figures above are therefore slower than the same person's all-out mile. By how much depends on the runner, and no sourced conversion was found for this article, so none is given.

Military personnel are not the public. They are medically screened on entry and required to train, so their standards cannot be read as what a typical adult of the same age would run. The Navy's "Good" category is also a category boundary, not a mean.

The age bands are administrative. The jump at 55 in the Navy tables and the flat stretches in the Army tables reflect how committees draw lines. Real ageing is smoother.

With those caveats, the tables support a plain reading: for adults under 50, somewhere between 9 and 12 minutes per mile is the range the services treat as acceptable, and 6 to 8 minutes is the range they treat as excellent.

How mile time changes with age

For the shape of the decline, the best evidence comes from masters athletes, because they keep training and keep racing, which removes the effect of simply becoming less active.

A review by Tanaka and Seals in The Journal of Physiology summarised the pattern across endurance sports: peak endurance performance is maintained until approximately 35 years of age, followed by modest decreases until 50 to 60, with progressively steeper declines after that. The main driver they identify is falling maximal oxygen uptake, with a lower lactate threshold contributing. Running economy, the oxygen cost of a given pace, does not change with age in trained adults. They also note that much of the decline is tied to a reduction in how hard and how much people train as they get older, which is a partly modifiable cause.

A longitudinal study by Lepers, Burfoot and Stapley followed 40 runners (39 men, one woman) who each ran a marathon under three hours in five consecutive decades. Their running speed fell by 0.67% per year on average, which the authors put at less than 7% per decade at least to age 60. They describe that as similar to earlier cross-sectional estimates of 6 to 7% per decade for men up to their late fifties. Their personal bests came at a mean age of 28.6.

Applied to a mile, a decline of about 7% per decade turns an 8:00 mile at 35 into roughly 8:34 at 45 and 9:10 at 55 for someone who keeps training. That is arithmetic on the study's rate, not a measured result, and it describes unusually consistent runners.

Age grading is the formal version of this idea. According to USATF Masters, the tables are compiled by World Masters Athletics and were most recently revised in 2023. They adjust a performance for the runner's age and sex. The factors themselves could not be opened from an official source for this article, so no age-graded mile times are quoted here.

Mile time, pace, speed and estimated VO2 max

Converting a mile time to speed is arithmetic and needs no source.

Converting to VO2 max is not arithmetic, and the only formula used here is the one published by The Cooper Institute for the 1.5-mile run: VO2 max = (483 ÷ time in minutes) + 3.5. The Institute's page does not state units; VO2 max is conventionally reported in ml/kg/min, and the table below assumes that. The formula sits alongside the Institute's account of how the 12-minute run was validated in 115 US Air Force officers and airmen, in whom field performance and measured VO2 max correlated at 0.897. The Institute describes the 1.5-mile and 12-minute tests as interchangeable.

Source: formula from The Cooper Institute (Farrell, 2018). Values are calculated and apply to a 1.5-mile effort, not a single mile.

Do not put a single-mile time into this formula; it is published for the 1.5-mile distance. The validation sample was Air Force personnel, so the estimate may be looser for other groups. For what those values mean at different ages, see the tables of VO2 max by age; for how a wrist estimate compares with a field test, see how accurate the Apple Watch VO2 max figure is.

What is not worth doing

Comparing yourself with an unsourced percentile chart. A table that says the "50th percentile" 40-year-old man runs a mile in some exact time is describing whoever uploaded runs to one platform, if it is describing anyone.

Treating the mile as a health test on its own. Endurance is one marker among several. The site's pieces on grip strength by age and how many push-ups an adult should manage cover the strength side.

Timing a mile from a GPS watch on a winding path. A track, where four laps of lane one is 1,600 metres and a mile is about nine metres more, removes most of the measurement error.

Running an all-out mile cold, once a year, to "see where things are". A maximal effort without recent training says little about trainable fitness. A steady 1.5-mile effort after a few weeks of regular running says more.

Assuming the decline is fixed. Tanaka and Seals attribute much of the slope to reduced training.

What to actually do

Pick the comparison that matches the question. For "is this acceptable for my age", use the Navy or Army pass column. For "is this good", use the Navy's Good row. For "how am I ageing", compare only with your own earlier times.

Test over 1.5 miles if the aim is a fitness estimate. It is the distance the Cooper formula is published for, and it maps directly onto the Navy table without conversion.

Use a track or a measured flat course, and repeat under the same conditions.

If running is not possible, measure walking. Walking a mile at 3 mph takes 20 minutes and at 4 mph takes 15; which of those is typical at a given age is covered in the article on average walking speed by age.

Expect slow change after 35 and plan for it. The evidence supports modest decline to the fifties for people who keep training.

Questions people ask

What is the average mile time? No measured average exists for the general adult population, because no representative sample has been timed. Sourced military standards put an acceptable pace for healthy adults under 50 at roughly 9 to 12 minutes per mile and an excellent one at 6 to 8 minutes, depending on age and sex.

What is the average mile time by age? Using the US Navy's minimum passing pace as a guide: for men, 9:00 per mile at 20–24, 10:20 at 40–44, 11:10 at 50–54 and 12:35 at 60–64. For women, 10:20, 11:30, 11:40 and 13:09. These are thresholds over 1.5 miles for serving personnel, not population averages.

What is a good mile time? The Navy's "Good" category starts at 8:00 per mile for men aged 20–24 and 9:30 for women, slowing to about 10:10 and 11:10 at 50–54. Its top category is around 5:40 to 6:25 for men and 6:30 to 7:20 for women across those ages.

What is the average mile time for a man? There is no sourced population figure. Military pass standards for men run from about 9:00 per mile in the early twenties to about 11:00 in the late forties and 12:35 in the early sixties.

What is the average mile time for a woman? Again, no population average has been measured. The Navy's passing pace for women is 10:20 per mile at 20–24, 11:30 at 40–44 and 13:09 at 60–64; the Army's two-mile pass works out to about 11:23 per mile at 22–26 and 12:00 at 52–56.

What is the average mile run time for beginners? No sourced figure exists for beginners as a group. The military minimums are a reasonable first target: about 9 to 10 minutes per mile for men under 40 and 10 to 11:30 for women. Mixing running with walking is fine; the Navy test itself permits it.

How long does it take to run a mile? For healthy adults, most sourced standards fall between 6 and 13 minutes. At a 6 mph jog a mile takes 10 minutes; at 7.5 mph, 8 minutes. Top Navy scores correspond to between 5:30 and just under 10:00 per mile depending on age and sex.

What is the average mile walk time? Walking a mile takes 20 minutes at 3 mph and 15 minutes at 4 mph. Measured walking-speed norms by age are a separate body of research from running standards and are covered in the article on average walking speed by age.

Is a 10 minute mile good? It depends on age and sex. Held over 1.5 miles, a 10:00 pace meets the Navy's Good threshold for men of 50 and over and women of 30 and over, and is a passing pace for men of 35 and over and women of every age band. For a man in his early twenties it would not pass the Navy test.

Is an 8 minute mile good? Yes, by published standards. An 8:00 pace over 1.5 miles is the start of the Navy's Good category for men aged 20–24 and faster than that category requires at every older age. For women it is close to the Army's maximum-score pace of 7:45 to 8:00 per mile through the mid-forties.
