First 5K What is the average 5K time?

What is the average 5K time?

In the fall of 2004, 13 runners lined up in a London park for a free, timed 5K. The organizer, Paul Sinton-Hewitt, had been badly hurt while training for a marathon and missed the social side of running, the coffee with friends afterward. "I didn't know who was going to join me on that day," he told the AP twenty years later. That run became parkrun, now held every week in parks around the world.

In 2004, the average parkrun time was 24:07. In its 2023-24 report, parkrun put it at 32:39, and said that's on purpose: "The slowing of our average time reflects our ambition to attract those for whom physical activity may not be the norm." A slower average there means more people who'd never call themselves runners are showing up. That's a good thing.

US races tell a similar story. RunRepeat and the IAAF (now World Athletics) looked at US 5K results from 2009 to 2018. In 2018, the average finish was 39:02, about 12:34 a mile: 35:22 for men and 41:21 for women. That's slower than in 2009, when the average was 35:30. Here's how 2018 looked by age.

Average 5K finish times in US races, 2018, from RunRepeat and the IAAF. parkrun results are not included.

These are averages of everyone who crossed the line, walkers included. And notice how little the numbers move through the middle decades: from the 20s to the 40s, the average slows by about 3 minutes for women and about 2 for men.

What is a good 5K time for a beginner?

Caroline Noon started running at around 50, and she started parkrun in 2014. Her first one didn't go to plan. "My ambition was only ever not to stop," she told the AP. "I stopped the first time. … I just assumed I'd not be embarrassed and I'd walk home. But I kept coming. Now it's been 10 years." By then she'd done more than 320 parkruns.

Her worry is the most common one. parkrun's CEO, Russ Jefferys, told the AP that the big barrier for people who sign up but never come is "this misunderstanding that it's a race, that people won't be fit enough or fast enough."

So here's a good beginner's 5K time: one you finish, feeling like you'd come back next week. If you'd like a number, a first 5K between 30 and 45 minutes sits right around the averages, and under 30 minutes is faster than average for every age group in the 2018 data. Run-walking the whole way is a perfectly good plan, too. Plenty of beginner plans are built on it, including two in the list above.

A 5K needs no special race-day food. The food that matters is in the training weeks, when many new runners run more but eat the same, or less. Eating enough to cover your runs is what lets the training work. Fall short and you'll notice: tired all the time, poor sleep, getting sick more, a short temper, heavy legs, and stalled times.

How much does age change your 5K time?

Betty Lindberg didn't start running until she was 63. At 97, she ran a 5K in Atlanta in 55:48, a world record for women aged 95 to 99, beating the old mark by more than 30 minutes. Her method? "I simply stroll, as quick as I can," she said.

Age does slow you down, but gently, and later than most people expect. In the 2018 race data, the averages barely shift between your 20s and your 40s. The bigger steps come after 50: women in their 50s averaged about 5 minutes slower than women in their 20s, and men about 3. If you'd like to compare yourself fairly with runners of any age, try an age-grading calculator. It adjusts your time for your age and sex, so a 50-year-old and a 25-year-old can see how their times stack up.

Here's the encouraging part. The people with the most room to improve are the ones who are newest to training. If you're just starting, at 25 or at 65, your first months are when you have the most to gain.

Your first 5K is a starting point, not a test

In May 2024, the country singer Jelly Roll ran his first 5K, the 2 Bears 5K in Los Angeles, hosted by the comedians Bert Kreischer and Tom Segura. Nobody was timed. "I couldn't walk a mile when I started trying to do this back in January," he told Men's Health. "I left here feeling really motivated." Then he named his next goal: "Next year, half marathon. We're saying it right now."

That's what a first race is for. It isn't a grade. It's a starting line. Your first 5K time is your baseline, the number every run after it gets measured against, and it's what makes your next time mean something.

So record it, then train for a few weeks and watch what happens. By about week 8, your easy runs start to feel easier, with a lower heart rate at the same pace, and an Apple Watch is accurate enough to show it. Your record does more than cheer you on, too. Your recent paces and heart rate are a decent guide to what you're ready to run next, which is how your easy days can stay truly easy and your harder days can be hard enough to count.

How to run a faster second 5K

In 1996, Josh Clark wrote a nine-week walk-run schedule to help his mother start running. He called it Couch to 5K, and today the NHS recommends it. "Almost always, we start out going too fast or too far," he told CNN. "I was writing it with the love of a son for his mother. I wanted this to be a good experience for her. I didn't want her to get hurt."

His advice holds for your second 5K, too. Getting faster mostly means running a little more, and keeping most of it easy. Easy running is the base everything else stands on, and a short session of faster running adds speed on top of it. Add a short strength session or two, because strength work prevents more injuries than stretching does. And grow slowly: lots of running injuries start with one run that's much longer than anything you've done lately. Most second-5K plans take 6 to 12 weeks.

Eat to match the training, too: more on interval and long-run days, normal on rest days. Runners need more carbs and protein than people who don't train, so refill with both after a run, and some protein every 3 to 4 hours helps your legs repair. That's how the work turns into speed. Losing a little weight works, too, done gently. The size of your calorie deficit drives fat loss, so running alone won't do it. Take the deficit from the day's food overall, never the meals around your runs, and keep it slow: about half a percent to one percent of your weight a week keeps more muscle and lowers the odds of getting sick or hurt.

Race day

Coach Jenny Hadfield has a simple way to pace a first 5K: give each mile a color. Mile 1 is yellow, easy enough to talk. Mile 2 is orange, a little harder. Mile 3 is red, and the final kick is "Fire." "The body doesn't know pace. It knows effort," she writes. Her last tip is the one to carry to the start line: "You only get to run your first 5K once a lifetime. Take it all in, run for the finish rather than the watch, and celebrate your accomplishment."

So start slower than you want to, walk when you need to, and save the fast part for the last half mile. Look at your time after the finish, not during. That number isn't a verdict. It's the first entry in your log, and the one every run after it gets to beat.

Caroline Noon stopped during her first parkrun and kept coming back for 10 years. The time on the clock was never the point. Coming back was.

Find a 5K, or a parkrun this Saturday, and go get your number.
