What's a Good 5K Time? Average Running Speed by Age and Sex

"Good" depends on who's running. A 5K time that puts a 25-year-old in the middle of the pack would put a 60-year-old near the front, and a time that took two years of training to reach is a different achievement from one reached in your first month. So the useful question isn't whether a time is good in general, but how it compares with other runners of your age and sex.

The short answer: for runners in their twenties, the middle of the field (faster than half of runners) is 22:31 for men and 26:07 for women. A first-month runner, at the Beginner level, finishes around 31:30 for men and 35:30 for women. From the mid-thirties on, every one of those numbers gets slower, year by year, and the tables below show by how much.

What counts as a good 5K time

The standards split runners into five levels. Each level is a finish time: run it or faster and you're ahead of that share of runners your age and sex. Intermediate is the middle: half of runners are faster, half are slower, which makes it the honest answer to "what's an average 5K time". The training notes beside each level are a rough guide to what it usually takes, not a rule.

Two things are worth knowing before you read your own time against this. First, the comparison is with runners, not with everyone: someone who never runs isn't in the tables, so finishing at the Beginner level already puts you ahead of the people still on the couch. Second, the levels are a ladder rather than a pass mark. Novice at six months is right on schedule, not a failure to be Intermediate.

A practical way to use the table: if your time is at or just under a level, that level is where you are; the next level up is a realistic goal for your next training block. At age 30 the step from Novice to Intermediate is 3:47 for men and 4:01 for women, and the training notes put about eighteen months of regular running between the two. A focused 5K training plan gives that running a direction.

Good 5K times by age: men

The tables keep almost the same times from 20 to 30, then slow a little every five years. By 50, the Intermediate time is about three minutes slower than at 30; by 70, about eight. An age in between two rows sits between them: a 42-year-old's standard is between the 40 and 45 rows.

Good 5K times by age: women

Women's standards follow the same shape: level from 20 to 30, then slower with each five years. At 30, each women's level is about 13 to 18 percent slower than the men's level beside it. Compare yourself with your own table: at 30, a 26:00 is Novice in the men's and Intermediate in the women's.

The tables go from age 10 to 90. For your exact age, and a percentile rather than a band, type your time into the running standards tool: it works out the in-between ages and shows how much faster the next level is, in total and per mile.

Average running speed

Speed and pace are the same thing turned around. Pace is minutes per mile; speed is miles per hour. To convert, divide 60 by your pace in minutes: a 10:00 mile is 6 mph, an 8:00 mile is 7.5 mph, a 6:00 mile is 10 mph. The same works in kilometres: a 6:00 kilometre is 10 km/h.

Here is the 5K at every level as a speed, for a 30-year-old. The Intermediate row is the median runner, the closest thing to an "average running speed" for a race effort: about 8.3 mph (13.3 km/h) for men and 7.1 mph (11.5 km/h) for women.

These are race speeds: the pace held flat out over 3.1 miles. Everyday running is slower. Most of a sensible week is easy, conversational running, well below race pace, so the speed you see on a treadmill during an ordinary run will usually sit under these numbers. That's how it should be; easy pace explains why.

Average running speed by distance

The longer the race, the slower the speed anyone can hold. Here is the median (Intermediate) runner at age 30 at each distance the standards cover, from a mile to the marathon. Men lose about 1.7 mph between the mile and the marathon, and women about 1.5 mph.

In kilometres per hour, the median 30-year-old man runs the mile at 14.6 km/h and the marathon at 11.8 km/h; the median woman, 12.5 km/h and 10.2 km/h. If you know your pace at one distance and want a finish time at another, the pace calculator does the conversion, and the marathon and half marathon pace chart lists the common goal times.

Average running speed by age

Speed follows the same curve as the 5K tables, because it's the same data. This is the median 5K runner's speed at each age, in mph with km/h beside it.

The decline is gentle at first and steeper later: the median man gives up less than a fifth of a mile per hour from 30 to 35, and more than half a mile per hour from 75 to 80. Because the standards compare you with runners your own age, slowing down along this curve still leaves you at the same level.

How fast can a human run?

The standards above are for distance running. Sprinting is a different scale. The 100 metres world record, 9.58 seconds, works out to an average of about 23.4 mph (37.6 km/h) over the whole 100 metres, start included, about two and a half times the median 30-year-old man's speed over a mile.

No one holds anything like that for long: speed falls steadily as the distance grows, which is why the mile, the 5K and the marathon each have their own tables. For an everyday runner, the useful number isn't a top speed but a pace you can hold for the whole race, and that's what the 5K tables measure.

A good time for your first 5K

For a first race, the good time is the one where you finish feeling you could have gone a little faster. The Beginner level (about 31 to 36 minutes for adults under 40) describes runners about a month in, and plenty of first 5Ks take longer, with walk breaks. That's normal, and it counts.

• Not running yet? A couch-to-5K plan gets you from walking to running 30 minutes in about eight weeks; the training plans guide lays one out, and how to start running covers the first month.
• Run the first mile slower than feels right. Race adrenaline makes the start feel easy, and a first mile run too fast is paid back in the last one.
• Your first time is your baseline. Whatever it is, it's your PR, and the next level up in the table is your next goal.
• Pick a friendly course. A flat, well-marked 5K with a big field is the easiest place to get a first time you're proud of.

Moving up a level

Going from one level to the next is mostly about consistency: running three or four times a week for months, with most of it easy. On top of that base, a 5K plan adds one harder session a week.

1. Find your level: put a recent time into the running standards tool.
2. Set the next level up as a goal, and turn it into a pace with the pace calculator.
3. Follow a six-to-eight-week 5K plan: mostly easy miles, one session of intervals or a tempo run (the workout types guide explains each), and a longer run at the weekend.
4. Race it, then check the table again. A new time also gives you better training paces: VDOT turns one recent race into five of them.

Put your own time on the board

A time trial on your own works, but a race gives you a measured course, a chip time and people to chase. RaceRove lists thousands of upcoming 5Ks in every state: browse 5K races across the US, find 5Ks near you, or start from a state, such as 5Ks in Texas, California or Florida. Thanksgiving week has more 5Ks than any other week in the listings, so the turkey trots are an easy place to find a first race. Ready to go longer? The same standards cover 10Ks too.
