Average 5K time: what's a good 5K time, by age and level

The average 5K time is about 35 minutes. More precisely, the middle finisher in RunRepeat's race-results dataset, built from 35 million results across more than 28,000 races over 20 years (updated March 2024), crosses the line in 34:37. For men the median is 31:28. For women, 37:28.

That's the number. The rest of this post is what counts as a good 5K time, how the average 5K time by age shifts, and what actually makes you faster. If you'd rather your training paces came from your own fitness instead of a crowd's, that's what an adaptive running plan is for.

Average 5K time: the numbers

RunRepeat publishes its full percentile tables, so you can see more than just the middle. Here's a slice of them:

Source: RunRepeat. Read each row as "this share of finishers ran faster": 10% of all runners beat 25:20, half beat 34:37, and 90% beat 50:04.

The median 34:37 works out to about 11:09 per mile, or 6:55 per km. The men's median is about 10:08 per mile (6:18 per km), the women's about 12:04 per mile (7:30 per km). That's our arithmetic, using 5K = 3.107 miles.

A note on the word "average". These are 50th-percentile times: the runner in the exact middle of the field, not a mathematical mean. For race results that's the more useful number, because a handful of walkers at the back can drag a mean around.

And if the 5K is a stepping stone rather than the destination, the same approach scales up: a half marathon plan that keeps your lifting is built on the same mostly-easy running with a little fast work on top.

What is a good 5K time?

"Good" depends on who's asking. A few honest reference points, all from the same dataset:

• ›Sub-35 is above average. RunRepeat's own phrasing: to be an above-average 5K runner, aim to finish faster than 35 minutes.
• ›Sub-30 is a strong first goal. RunRepeat notes that only 30% of participants run under 30 minutes. That's 9:39 per mile, or 6:00 per km.
• ›Sub-25 puts you near the front. The fastest 10% of the whole field finish in 25:20 or quicker.
• ›Sub-19 is rare air. The fastest 1% run 18:40 or better.

Women: per RunRepeat, a 30-minute 5K makes you faster than more than 70% of women in the data. Men: the same 30 minutes beats more than 65% of men.

A good 5K time by level

The dataset gives you where you sit in the crowd. This table is a coaching-practice guide for what a time usually means, not a dataset:

If you're brand new, the first target is finishing. Our guide to 5K training covers the build from zero, with lifting kept in, and a first race is about learning the distance, not judging yourself by it.

Average 5K time by age

RunRepeat's percentile page doesn't break its numbers down by age. A different dataset does. RunBundle publishes median 5K times by age category, built from times submitted by users of its calculators. As of its September 2026 update:

Two caveats before you compare. First, these medians are several minutes faster than RunRepeat's, because people who use running calculators tend to be keener runners than the average race field. Second, RunBundle's numbers update as people submit times, so they'll drift. Use the table for the shape, not as gospel.

The shape is the useful part: times barely move from your twenties into your forties, then slow gradually. That matches the research on masters athletes, where peak endurance performance holds until roughly 35, declines modestly until 50 to 60, then more steeply after that (Tanaka and Seals, 2008). That review also found the decline is largely tied to older athletes training at lower intensity and volume, which is a more encouraging message than "you're old now".

Why the average 5K is slower than you'd think

The 5K is the entry distance. RunRepeat's State of Running report found the slowest average pace of any race distance at the 5K, and attributes it to the 5K being the distance with the most novices. Charity runs, fun runs, people pushing strollers, groups walking together: they're all in the data.

That's not a criticism of the average. It's a reason not to panic if your first 5K lands near it. You're being compared with everyone, including people who walked the whole thing on purpose.

How to get faster at the 5K

The short version: run more often, keep most of it easy, add one quality session a week, and lift. The detail:

• ›Consistency first. Three runs a week for three months beats five runs a week for three weeks.
• ›Most runs easy. Conversational pace, slower than your ego wants. This builds the aerobic base the 5K still leans on.
• ›One quality session. Intervals of 400 m to 1 km, a tempo run, or a fartlek. If you're unsure which, fartlek explained sorts out which hard run does what.
• ›A longer easy run. 40 to 70 minutes. It's the same building block that half marathon training turns up later.
• ›Pace it right. The first kilometer should feel controlled. The last one shouldn't.

Your ceiling is partly set by your aerobic capacity, which is why runners obsess over what a good VO2 max is. The good news is that the training above is also how you raise it.

Keep lifting

Lifting doesn't cost you speed at this distance. A systematic review by Blagrove and colleagues (2018) found strength training generally improved running economy by 2–8% in the studies that measured it, and time-trial performance over 1.5 to 10 km also tended to improve. The authors suggest two to three strength sessions a week. For how to fit that around runs, runners strength training covers what to lift and where it goes in the week.

The scheduling rule that matters most: keep heavy legs away from your interval day. The day after is fine. The day before isn't.

Hybrid racers

If your races happen in a Hyrox venue rather than on a road, the running still matters, but the clock tells a different story. Hyrox times depend as much on the stations as on your 5K, so don't judge one by the other.

How to find your realistic 5K goal

The average is a curiosity. Your goal should come from your current fitness:

1. ›Run a time trial or a parkrun-style 5K. That's your baseline.
2. ›Aim a little faster, not a lot. A minute or two off over a training block is a realistic target for most newer runners; experienced runners fight for seconds.
3. ›Retest after 6 to 8 weeks. Compare with yourself, not the crowd.

If you haven't started yet, running for beginners is the place to begin. Run slowly, walk when you need to, and the 5K comes.

How exrsz handles this

exrsz builds a periodized 5K plan from your goal, schedule, level and equipment, with your runs and lifts in one plan so intervals and heavy legs don't land back to back. It adapts each week to how training actually went, so your paces follow your real fitness rather than a crowd median.

FAQ

What is the average 5K time?

About 35 minutes. RunRepeat's dataset of 35 million race results puts the median finisher at 34:37, with 31:28 for men and 37:28 for women.

What is a good 5K time for a beginner?

Finishing is the first goal. After that, sub-30 is a strong target: RunRepeat notes only 30% of participants run under 30 minutes.

What is the average 5K time by age?

In RunBundle's user-submitted data, median times stay fairly flat from the twenties into the forties, then slow gradually from the fifties on. Its medians run faster than race-field data because keen runners submit more times.

Is a 25-minute 5K good?

Yes. In RunRepeat's data, the fastest 10% of all 5K finishers run 25:20 or quicker, so 25 minutes puts you near the front of most fields.

How long does it take to get a good 5K time?

Most newer runners see clear improvement over a 6 to 8 week block of consistent training. Bigger jumps take months of mostly easy running with one quality session a week.
