Let’s be honest to each other from the start: Runners love numbers—splits, PRs, finish times.

Sure, those digits can fuel progress, but they can also get in your head if you let them.

Here’s the deal: your race time isn’t your worth. It’s just one checkpoint on your running journey.

I’ve been there—obsessing over whether my 10K stacked up against some “average” I saw online, or whether my marathon time meant I was “good enough.”

That stuff will eat you alive if you let it.

The smarter way? Use times as tools.

Let them guide your growth, not define your identity.

This cornerstone isn’t a dry stats dump—it’s your field guide.

And that’s what I want to talk about today, in depth.

Most specifically, I’ll break down average times across 5K, 10K, half, and full marathons. 

I’m gonna also dig into what really affects your speed (hint: it’s more than age and gender). And I’ll give you the coaching takeaways you can actually use—training plans, benchmarks, and perspective.

Ready?

Let’s get to it.

Key Running Terms (That Actually Matter)

Before I get into the meats and potatoes of today’s article, let me clear up a few terms every runner should know:

Gun Time vs. Chip Time

Here’s the quick rundown: gun time is the “official” clock from the starter’s pistol to when you cross the finish.

Chip time is your actual start-to-finish run, tracked from when you step over the starting mat to when you hit the finish.

For most of us non-elites, chip time is the truth. Gun time is more for the winners up front.

Trust me—if you’ve ever shuffled in a sea of 5,000 runners for three minutes before even crossing the start, you know why chip time matters.

Age Grading

Think of this like a golf handicap for running.

Statisticians figure out what’s “world best” for every age and gender, then adjust your time accordingly.

For example, a 70-year-old running a four-hour marathon might get an age grade that says,

“Hey, that’s like running a three-hour marathon at age 30.” Pretty cool, right?

It lets you chase fair comparisons as you age.

I’ve seen 55-year-olds use it to stay motivated—no, you won’t beat your 25-year-old self head-to-head, but you can chase the same age-graded percentage now.

What’s a “Good” Time?

Ah, the runner’s favorite bar debate. The truth: “good” is relative.

But a rule of thumb says if you’re faster than half the runners in your race, you’re doing solid.

For context, the median half marathon finish is around 2:10:00.

So, anything under two hours?

Most would call that good.

Same with marathons: sub-4:00 is the mark many chase since the average is about 4½ hours.

But context is king.

A 60-year-old dropping a 4-hour marathon? Phenomenal—that’s well under the 4:51 average for that age group.

Meanwhile, a 25-year-old with the same time might shrug it off as “just okay.”

Running Level data backs this up: a “good” 5K time for men is ~22:30 and for women ~26:00. Top-10%?

That’s way faster. But the main thing: “good” is whatever time feels like a strong effort for YOU.

Hit a new PR? That’s always good.

Beginner vs. Recreational vs. Competitive

Here’s where labels help:

  • Beginners (new runners or just starting structured training) often finish a 5K in 30–40+ minutes. A 20-something guy new to running might average ~31:30 (10 min/mile). Walk breaks? Totally normal. You’re just building the base.
  • Recreational runners (regular joggers who run for fitness) usually land in the middle of the pack. That same 20-something guy might be at ~22:30 for 5K (7:15/mile pace). He’s running a few times a week, has some training history, and feels comfortable in races.
  • Competitive runners (age-group crushers, club racers) are the ones hunting podiums. That 25-year-old guy might clock 19:45 for a 5K (~6:20/mile), with the faster ones dipping closer to 17:40 (sub-5:45/mile). These are the folks stacking higher mileage, hitting speedwork, and training with real purpose.

And the gap? It’s huge. Beginners can run 3–4 minutes per mile slower than competitive athletes.

Totally normal. So if you hear “a good 10K is 50 minutes,” remember that’s for trained runners.

A brand-new runner might take 1:15, and that’s still a massive accomplishment. Six miles isn’t a joke.


Average 5K Times by Age and Gender

The 5K is where a lot of us start. It’s just 3.1 miles—short enough that you can jump in as a beginner, but long enough to make you question your life choices if you go out too fast.

So, what’s “average”? Looking at big datasets, the median 5K time across all ages and genders is about 36 minutes—roughly 11:30 per mile pace.

Break that down: men sit around 32 minutes, women around 39 minutes.

If you’re in the 30–40-minute range, congrats—you’re right in the heart of the pack.

I’ll be honest—when I ran my first 5K, I was nowhere near those numbers.

I think I was flirting with a 12-minute mile, and it felt like I’d just survived a war.

But that’s the beauty of the 5K: it doesn’t take much training before you start chopping off minutes.


Age Makes a Difference (But Not as Much as You Think)

Younger runners usually move quicker—up to a point.

A study that crunched over 600,000 5K results found that teenagers in the 15–18 age group had the fastest medians:

  • Boys: 26:16
  • Girls: 33:44

No shocker there—high school cross-country kids live on carbs and adrenaline.

From your 20s on, times start to slow little by little. Here’s the reality check:

  • Men in their 30s average around 30:30. By 50–59, they’re at 33:04.
  • Women in their 30s average 36:34, and by 50–59, it’s 41:05.

And here’s what fires me up—runners in their 70s are still posting solid times: around 39:38 for men and 47:56 for women.

Think about that. Seventy-plus years old and still clicking off 5Ks under 50 minutes. That’s not just running—that’s winning at life.


Men vs. Women: The Gap

Yes, men tend to run faster on average, mostly because of things like muscle mass and VO2 max. The difference usually sits at about 15–20%.

For example:

  • At age 30: men average 30:30, women 36:30 (~20% gap).
  • At age 70: men 39:38, women 47:56 (~21% gap).

But don’t get it twisted—plenty of women torch men in races.

I’ve been passed by women half my size and twice my speed. And at the elite level, the difference is only a couple of minutes (men’s winner might be ~15 minutes, women’s ~17). 


What Fast vs. Slow Feels Like

Run a 5K under 20 minutes?

That’s a redline effort. Your legs scream, your lungs are on fire, and lactic acid is pouring in like cement.

On the flip side, if you’re cruising at 45+ minutes, it feels more like a jog or a run/walk—you might even chat with a buddy along the way.

Here’s the truth: “fast” and “slow” are relative.

A beginner fighting for a 30-minute 5K might feel like they’re dying, while an experienced runner calls 30 minutes their easy day.

The cool thing about 5Ks is everyone finishes in the same ballpark—whether you’re flying in at 18 minutes or grinding through 50, you’re all on the same course, sharing the same struggle.


Training That Moves the Needle

If you want to shave time off your 5K, here’s the simple truth:

  1. Consistency builds your aerobic base.
  2. Speedwork—intervals, tempo runs—trains your body to handle the burn.

That’s it. You don’t need fancy gear.

You need sweat equity.

For beginners, just running without walk breaks can cut your time from 45 minutes down to 30–35 minutes in a few months.

I’ve seen it happen with athletes I’ve coached—and I’ve lived it myself.

If you’re chasing sub-20 or sub-22 minutes, though, you’ll need structured intervals and maybe a little body-weight drop.

Physics is real—studies show that losing a few pounds (within healthy ranges) can give you 1–2 seconds faster per mile per pound.

I’ve also written a whole article about it.

That’s not me telling you to obsess over weight, but it’s proof that running rewards both fitness and physics.


The Hidden Truth About “Average Times”

Here’s the catch: most of these average 5K times come from people who actually sign up for races.

They’re already training. The couch-to-5K crowd—the ones taking an hour or more—don’t usually show up in the stats.

So if your time is way above “average,” don’t sweat it. You’re already ahead of everyone still parked on the couch.

And here’s the best part: with just a few months of consistent training, it’s common to cut 5+ minutes off your time.

That’s why I always tell runners: stop comparing to the crowd. Benchmark against yourself. Your last 5K is the only competition that matters.


Average 10K Times by Age and Gender

The 10K is that tricky middle ground—it’s long enough to test your endurance but short enough that you still feel like you should be hammering.

It pulls in everyone: beginners looking for a new challenge and experienced runners chasing that sub-40.

So, what’s “average”? Globally, the typical 10K time hovers around 58 minutes (RunRepeat data).

Most everyday runners feel good breaking an hour—that’s a classic milestone.

For men in their 30s, average finish times run about 54–57 minutes.

Women in that same age group? Around 1:04–1:06. That’s not me talking, that’s data speaking. Now let’s break it down by age.

Average 10K Times by Age

According to the same large-scale data compiled by RunRepeat I mentioned before:

  • Teens (0–19): Men ~46:30, women ~1:00:20. Keep in mind, only the speedy young guns are racing this distance, which drags those averages down. The 16–19 male group averaging ~46:36 is nuts.
  • 20s: Men ~51–54 minutes, women ~59–62. This is peak running decade—lots of men under 50 minutes, lots of women under the 1-hour barrier.
  • 30s: Men about 54:20 (early) creeping to 55:30 (late). Women ~1:02–1:03. Not much slower than your 20s.
  • 40s: Men ~53–56 minutes. Women ~1:02–1:04. Some men even pick up speed in their early 40s if they stay consistent.
  • 50s: Now the slowdown hits. Men early 50s ~56:12, late 50s ~59:00. Women ~1:04 (early) to ~1:07–1:10 (late). Lots of runners cross the 60-minute line here.
  • 60s: Men average ~58–59 until mid-60s, then about 1:03. Women ~1:09 early, then ~1:18+ late. Fewer runners, wider spread in fitness.
  • 70s and up: Data is thin, but the 65–99 group shows men ~1:03:02, women ~1:18:57. Plenty of folks walking more here, which explains the gap.

Here’s the kicker: if you run under an hour, you’re ahead of about 60% of runners worldwide (with the median sitting near 1:02). Want to push beyond average? For men, that means chasing under 45. For women, under 50. Elite club runners? We’re talking sub-40 for men and sub-45 for women.

Road vs. Trail: Context Matters

Let’s not forget—terrain changes everything. A flat road 10K is one thing.

A muddy, hilly trail 10K? Whole different beast. A road runner who normally hits 60 minutes might suddenly be at 1:15 on a tough trail. That’s why pacing a 10K properly really matters.

Stop comparing apples to oranges. On trails, finishing strong matters way more than the clock.

The Mental Game of the 10K

Here’s where things get spicy—the 10K is a graveyard for pacing mistakes.

It’s short enough that you think you can go out 5K-hard, but long enough to punish you when you do.

I’ve seen countless runners crush the first two miles and then crawl home by mile 5.

The 10K demands mental toughness. You’ve got to train your brain to sit with discomfort for 40–70 minutes.

Personally, I’ve blown more 10Ks than I care to admit. Went out hot at 5K pace, only to hit the wall by mile 4.

Brutal.

The trick is practice: tempo runs at 10K pace, learning how your body should feel at mile 1, 3, and 5.

If you do it right, the last mile will feel like a 5K finish—but with way more fatigue in the tank.

Linking Your 5K to 10K Pace

Quick math trick: your 10K pace usually runs 15–30 seconds per mile slower than your 5K pace.

So if you’re at an 8:00/mile 5K (~24:50), expect 8:15–8:30 pace for the 10K (~53:00 finish).

Elite runners? Smaller gap. Newer runners? Bigger gap.

Another shortcut: double your 5K time and tack on 1–2 minutes.

Run a 25:00 5K? You’re looking at about a 52-minute 10K.

This rough formula lines up with the averages we just went through.

Don’t Blame Endurance Alone

Here’s the contrarian truth: most people think they suck at 10Ks because they lack endurance.

Often, it’s not that—it’s mental pacing fatigue.

Running 6.2 miles hard is a skill.

If you don’t practice tempo runs at race pace, your brain freaks out after 20–30 minutes and begs you to slow down.

That’s why I tell my runners: treat the 10K as 80% physical endurance, 20% mental grit. Nail your pacing and practice tempo efforts, and your 10K will stop feeling like an unsolvable puzzle.


Average Half Marathon Times by Age and Gender

The half marathon is a beast of a race—13.1 miles (21.1 km). It’s long enough to test your grit, but still doable for most of us without the life-sucking grind of full marathon training.

That’s why it’s one of the most popular races out there.

You’ll see everybody on the start line: first-timers chasing a bucket-list goal, weekend warriors, and club runners trying to shave seconds off a PR.

Because of this mix, “average” times can be all over the place depending on who’s being measured.

The Big Picture

If we zoom out, the average half marathon finish time is around 2:14:59—that’s roughly 10:18 per mile (6:24/km) pace.

Men hover around 1:59:48 (just under two hours), and women around 2:24:03.

That’s based on 2022 data across recreational runners of all ages.

Now here’s the thing: going sub-2 hours is a big deal for the everyday runner.

For context, in a lot of races the median finisher lands somewhere between 2:05–2:15, and dipping under 1:50 usually puts you in the faster crowd.

Here’s the thing though.

When I joined my first HM, I was just happy to survive.

My finish time was nowhere near two hours. But once I got consistent—adding long runs and dialing in pacing—that sub-2 became realistic.

A few days ago I finished the Maybank HM at 1:27 (on a hilly and humid course).

That’s the beauty of this race: the numbers give you a target, and the training gives you a shot at smashing it.

Just give it time.

Breaking it Down by Age

Like most distances, half marathon performance usually peaks in your late 20s and 30s, but the drop-off doesn’t really kick in until much later.

Here’s what the data says:

  • 20s – Average finish: ~2:00–2:02. Men: low 1:50s. Women: low 2:00s. According to one study, the fastest female marathon age group is 20–29 with a 4:42:10 average. Halve that, and you’re looking at ~2:21 for the half. Of course, competitive women in their 20s are often clocking 1:40–1:50.
  • 30s – Pretty much the same as the 20s, often even better because of experience. Overall averages: ~2:02. Men: 1:50–1:55. Women: 2:05–2:10
  • 40s – Slight slowdown. Averages creep toward 2:10. Men: low 2:00s. Women: 2:15–2:20. That said, masters runners can be scary fast. Some research even puts men’s peak marathon age at 40–49.
  • 50s – Still plenty of runners under 2:20. Average: 2:20–2:30. Data shows women in their 50s–60s average around 2:25, men around 2:10–2:15.
  • 60s – Now we’re talking 2:45–3:00. Women: ~2:46. Men: 2:30–2:40. But don’t think age means slow. I’ve seen 60-somethings smoke me in races.
  • 70+ – Honestly, just finishing is the win. Most are running 3+ hours. But there are outliers—like that 80-year-old guy who ran 1:57. Yeah, world-class age-group performance is wild.

One thing worth pointing out: first-timers are often slower. A debut half with minimal training might take 2:30–2:45. With a bit of structure?

That same runner can cut it down to 2:10–2:20 on their next try. Experience really does shave minutes.

Why the Last 5K Hurts

Ever heard the saying, “The half marathon starts at mile 10”?

It’s true. A ton of runners cruise the first 9–10 miles, then hit the wall hard in the last 5K.

Why mile 10? A couple of reasons:

  • Most people only train up to 10 miles, so the body isn’t fully ready for that extra push.
  • Fueling mistakes show up—skip carbs or electrolytes mid-race, and you’ll pay for it.

I’ve been there. Once held a steady pace for 9 miles, only to slow by 30+ seconds per mile in the final stretch. Felt like I was running through cement.

And the data proves it: men slow down about 11.7%, women about 10% in the second half of the race.

Women, by the way, tend to pace more evenly. If you can run negative splits (second half faster than first), you’re in rare company—you nailed the pacing game.

How Training Shaves Time

You’ll hear that training can chop 10–20% off your time.

That’s no joke. If you’re new, just finishing might put you around 2:30. Train consistently for a year, and you could be running a sub 2-hour or faster.

Why? Because structured training raises your lactate threshold (so you can hold a faster pace longer) and builds endurance (so miles 11–13 don’t wreck you).

The formula works:

  • Long runs (12–14 miles).
  • Tempo runs at close to half pace.
  • Speed intervals for turnover.
  • And yes, gradually bumping mileage. A runner logging 15 miles per week who doubles to 30—carefully—will almost always see big gains.

But here’s the kicker: improvement happens when you rest. Most of my PRs came not from piling on miles, but from training smarter—quality workouts, recovery, tapering, and nutrition.


Average Marathon Times by Age and Gender

Let’s talk marathons. 26.2 miles (42.195 km).

It’s not just running—it’s guts, stubbornness, and maybe a little insanity.

You’ll see everything out there: pros flying through in just over two hours (yep, the men’s world record is about 2:01 and the women’s sits at ~2:14), all the way to everyday warriors grinding it out for 5–6 hours—or longer if they’re racing the cutoff.

So when we say “average marathon time,” we’ve gotta set the stage.

The Big Picture: Global Averages

One huge study, covering millions of marathon results worldwide, found the mean finish time is 4:29:53—let’s call it about 4½ hours.

That lines up with Runner’s World too, which puts the average around 4:32:49.

  • Men average: ~4:21:00 (9:57/mile pace)
  • Women average: ~4:48:45 (11:00/mile pace)

So yeah, about a 30-minute difference—roughly 10–12%. That lines up with the physiological gap we see in long-distance running.

And don’t forget, where you run matters. U.S. marathons tend to skew slower (lots of 5+ hour finishers), while some European countries post faster averages.

Breaking It Down by Age

Here’s where things get interesting.

In 5Ks and 10Ks, the young guns usually rule.

But in marathons?

The 40-somethings often hold their ground—and then some.

According to the data:

  • 20–29: Average ~4:28. Funny thing: the under-20s averaged 4:18 in one dataset. But that’s a tiny pool—mostly fit, sports-crazy teens. And let’s be real, plenty of 20-somethings undertrain, go out cocky, and blow up at mile 20. Been there, done that.
  • 30–39: Around 4:23. Yep, faster than the 20s. That’s the group that stuck with running and learned some discipline.
  • 40–49: Also about 4:23—basically tied with the 30s. In fact, this was the fastest age group overall. Men in their 40s averaged 4:11, while women in their 20s clocked the best female times at 4:42. Proof that wisdom and patience beat youth and overconfidence.
  • 50–59: Slips to about 4:31—only 8 minutes slower than the 30s and 40s. That’s nothing.
  • 60–69: Jumps to about 4:51. This is where the sub-5 marathon starts to feel like a bigger mountain, but plenty still crush it.
  • 70–79: Around 5:24. Most septuagenarians finish in that 5–6 hour range. Honestly, just toeing the line at 70+ is heroic.
  • 80–89: About 6:12, though that’s skewed by a handful of exceptional runners. Most 80+ folks who finish are walking some, but again—still out there. 

Here’s the takeaway: your 40s might be the sweet spot. Experience and mental toughness can balance out the small decline in VO2 max. From your 50s on, times start to creep up—but with solid training, you can hang strong for decades.

Men vs. Women: The 26.2 Showdown

We already said men average ~30 minutes faster. But pacing tells another story.

Research shows men slow down by ~15.6% from the first half to the second, while women slow by only ~11.7%.

Translation? Guys are more likely to go out hot, crash, and bonk. Women? They tend to run smarter, holding steady.

That’s why in the back half of marathons—and especially ultras—you’ll see women blowing past guys who went out too fast.

In fact, the performance gap shrinks the longer the distance. In marathons, it’s about 10%. In 5Ks, it’s closer to 17–18%.

I’ve been that overconfident guy more times than I care to admit—feeling invincible at mile 10, only to stagger through the last 10K.

Meanwhile, I’ve seen plenty of women cruise by me late in the race looking strong. Lesson learned: pace like a woman if you want to finish proud.

Where Do You Stack Up? (Distribution)

Let’s put some real numbers on this. In a big-city marathon:

  • Median (50th percentile): ~4:20–4:30. So if you finish around 4½ hours, you’re right in the middle of the pack.
  • Top 25%: Under ~3:55. About 30% of runners break 4 hours. Do that, and you’re ahead of the majority. For men, that bar is ~4:14; for women, ~4:42.
  • Bottom 25%: ~4:50–5:00. Roughly one in four runners comes in here—often older runners, or younger folks who had a bad day.
  • Back of the pack (90th percentile): ~5:40–6:00. Most races shut down around 6–6½ hours, so that’s where the tail end lands.

So if someone asks, “What’s a good marathon time?” here’s my no-BS answer:

Under 4 hours puts you in the top third. Under 3:30? That’s top 10%.

But honestly, just finishing 26.2 is something most people will never attempt. I don’t care if it takes you 3 hours or 6—crossing that finish line makes you part of a rare club.


Master Charts: Side-by-Side Distance Comparison

Sometimes it’s hard to make sense of all these numbers unless you see them lined up next to each other.

That’s why I love master charts. They let you check out average finish times for 5K, 10K, half marathon, and marathon—all broken down by age and gender.

Think of it like this: you can see how the average 30-year-old woman does in a 10K versus a marathon, or how a typical 50-year-old guy holds up across distances.

Here’s what we pulled together:

  • Age groups in 10-year chunks (20s, 30s, 40s, 50s, 60s).
  • Average times for men and women.
  • An “Elite/Club-Level” column to show what the top 5% are running. That’s not to intimidate you—it’s to give you a sense of what’s possible with serious, consistent training.

For example, the 30–39 bracket might look something like this (not exact numbers, but close enough to give you the picture):

  • 5K: Men ~30:30, Women ~36:30 (Elites: Men ~17:00, Women ~20:00)
  • 10K: Men ~55:00, Women ~1:02 (Elites: Men ~35:00, Women ~40:00)
  • Half Marathon: Men ~2:02, Women ~2:12 (Elites: Men ~1:15, Women ~1:25)
  • Marathon: Men ~4:20, Women ~4:40 (Elites: Men ~2:30, Women ~2:50)

When you look at it side by side, a few patterns pop out right away:

  • Average runners slow down a lot more across distances than elites. A guy in his 30s might run a 30-min 5K but need over 4 hours for the marathon. Meanwhile, an elite goes from a ~17-min 5K to a ~2.5-hour marathon. That’s the power of serious endurance training.
  • The gender gap shrinks the longer the race. At 5K, men are usually 15–20% faster. But by the marathon, the gap narrows to about 10–12%. Women hold their own—and sometimes outpace men—when the miles stack up.
  • Age hits the long stuff harder. A 60–69-year-old’s marathon time slows way more compared to their 5K than it does for someone in their 30s. Makes sense—running 26.2 miles in your 60s is no small feat.
  • Training beats age—at least for a while. I’ve coached plenty of 40-somethings who outrun untrained 20-somethings. The elite columns prove it: consistent training keeps you fast well into your middle years.

Okay, so averages are nice. But let’s be real—you probably want to know: Am I faster than most? Or am I still in the back of the pack?

That’s where percentile charts come in. Instead of just asking “What’s average?”, we can check where you land: top 10%, top half, back quarter, whatever. It’s both humbling and motivating.

Here’s the breakdown, based on massive datasets from Strava, Running USA, and RunRepeat:

  • Median (50th percentile): Dead middle. Half the field is faster, half slower. Example: ~36 min for a 5K, ~62 min for a 10K, ~2:10 for a half, ~4:30 for a full. If you’re faster than that, congrats—you’re officially “above average.”
  • Top 10% (90th percentile): This is the “pretty fast” club. You’re likely placing well in your age group at local races.
    • 5K: Sub-25 min overall (men ~23:30, women ~28:00)
    • 10K: Sub-48 (men ~45:00, women ~53:30)
    • Half: Sub-1:47 (men ~1:40, women ~1:53)
    • Full: Sub-3:31 (men ~3:22, women ~3:49)
      Breaking these marks means you’re one in ten. Not bad company.
  • Top 1% (99th percentile): This is rarefied air—club runner or semi-pro level.
    • 5K: Men ~17–18 min, Women ~21–22 min
    • 10K: Men ~36, Women ~41
    • Half: Men ~1:24, Women ~1:32
    • Full: Men ~2:45, Women ~3:11
      If you’re here, you’re basically winning or close to winning races.
  • Bottom 25% (slower than 75th percentile): Hey, no shame here—everyone starts somewhere.
    • 5K: ~44–45+ minutes
    • 10K: ~1:16–1:20
    • Half: ~2:40–2:45
    • Full: ~5:00–5:15
      And let’s be real—there are always walkers, first-timers, and people just out to finish. You won’t be alone.

Here’s what’s cool: percentiles help you set realistic but exciting goals.

Let’s say you run a 10K in 1:10. That’s about 60th percentile.

Breaking an hour bumps you into the top 40%—a huge jump. Or maybe you’re already top 20% in the 5K—why not shoot for the top 10% next?

And here’s a stat that blows most people’s minds: only ~30% of marathoners finish under 4 hours. So if you’re sub-4, you’re not just “good”—you’re in a select group.


What Really Impacts Your Race Times (Besides Age & Gender)

So yeah, age and gender matter. But let’s be real—those aren’t the only things standing between you and a faster finish line photo. Two runners the same age, same gender, same “category”?

One could cruise to a PR, the other could blow up halfway.

Why? Because running isn’t some standardized lab test. Life gets in the mix.

Training habits, sleep, stress, even the weather—these are the things that really tip the scale.

Let’s break it down.

1. Consistency of Training

Here’s the ugly truth: the best training plan is the one you actually follow.

Period.

A runner who laces up 5 days a week is going to crush someone jogging 1–2 times a week, even if their “talent” is the same.

Consistency is where the magic happens—your aerobic engine grows, your running economy sharpens, and your confidence soars.

I’ve seen it with my own athletes, and in myself.

A year of steady training beats any fancy shoe or supplement.

No shortcuts, just the grind.

Bonus: steady training lowers your injury risk and builds those small gains that stack up into something big.

If you only change one thing? Run more often. You’ll be shocked what 12 months of steady mileage can do.

2. Weight & Body Composition

Your body is the machine. Carry extra fat? That’s just dead weight slowing you down—especially when the hills kick in. Research backs this up and I’ve already talked about it here.

A classic study found that for every extra pound, pace slows by about 1.4 seconds per mile. Another showed higher body fat means slower marathon times.

Now, don’t go chasing crash diets. Lose muscle or under-fuel, and you’ll tank performance.

The goal isn’t “skinny runner mode”—it’s strong and lean.

Core and leg strength push you forward, while excess fat drags you back.

From experience, most runners naturally lean out with consistent training—that’s partly why their times improve.

And yes, there’s nuance. In ultras, a little extra body fat can help with energy reserves.

But for races under a few hours? Leaner (within healthy limits) usually means faster.

3. Sleep, Stress & Lifestyle

Let me be blunt—if you’re running on fumes, your race times are gonna suffer.

Sleep is the cheapest performance enhancer out there.

Eight hours isn’t luxury, it’s fuel. Studies show lack of sleep kills aerobic endurance. I’ve felt it: one bad night and the next day’s run feels like I’m dragging a sled.

Stress is another silent killer. Work drama, money worries, life chaos—all raise cortisol, which messes with recovery. Even if your training is dialed in, stress can tank your race.

Same with lifestyle. If you’re on your feet doing manual labor all day, you’re not lining up fresh. On the flip side, that grit you build from life’s chaos can also toughen you mentally.

Bottom line? Racing doesn’t happen in a bubble. Sleep more, eat real food, manage stress, hydrate—you’ll notice the difference.

4. Weather & Terrain

Mother Nature doesn’t care about your PR dreams.

The sweet spot for racing is about 50–55°F (10–13°C), cloudy, light breeze.

Anything hotter?

Expect to slow down. Rule of thumb: add 30 seconds to 1 minute per mile for every 10°F above ideal. And that’s if you’re well-trained.

Wind? Hills? Altitude? They all steal seconds—or minutes.

I’ve run marathons where the only difference between a 4:00 and a 3:45 was swapping a hot, hilly course for a cool, flat one.

That’s why seasoned runners always add context: “Yeah, it was 55 minutes, but it was on trails in July heat.”

Adjust your expectations, adjust your pacing, and don’t let the day beat you.

5. Pacing & Race Execution

Two runners, same fitness. One blows up at mile 3, the other cruises through strong.

What’s the difference? Pacing. Going out too fast is the #1 amateur mistake.

Blow the first half, and you’re crawling through the finish.

Smart pacing, fueling at the right time, even drafting in the wind—those tactics can chop serious time off your race.

I’ve seen runners slice minutes off just by practicing even splits in tune-up races.

Race execution is a skill, not just fitness. Nail it, and you’ll shock yourself.

6. Experience with the Distance

Your first marathon? Brutal. Second or third? Usually way better, even if your fitness hasn’t changed much.

Why?

Because you finally know what the distance feels like.

You know how to fuel, when the wall hits, and how to push through mile 20 without panicking.

That’s why average times you see online often reflect runners who’ve done multiple races at that distance.

If it’s your first? Give yourself grace. You’ll get faster just from experience.


Race Time Improvement Benchmarks

One of the biggest questions I get from runners—whether they’re just lacing up for the first time or they’ve been at it for decades—is this: “How much faster can I get, and how long will it take?”

The truth? Improvement isn’t a straight line. It’s more like a steep hill at the start that eventually levels out.

Here’s how it usually plays out in real life.


Year One = Jackpot Gains

If you’re new to running, congrats—you’re about to cash in on the biggest PRs of your life.

I’m not kidding.

Those first 6–12 months? Gold.

You might chop minutes off your 5K or even an hour off your marathon between your first and second go.

Why? Your body’s learning fast—lungs, legs, stride, everything.

Research shows new runners can boost cardio fitness in as little as 4–6 weeks, with big jumps a few months in.

I’ve seen it again and again: a beginner goes from a 60-minute 10K to 50 minutes in one year, then cracks 45 the next.

But here’s the kicker—going from 45 to 40? That’s not a one-year project.

That can take several years of grinding.

The curve shoots up quick, then it flattens.


Plateaus & Diminishing Returns

After the honeymoon? Gains get harder. You’re closer to your ceiling.

That’s why nobody drops 30 minutes off their marathon every year—we’d all be Eliud Kipchoge by now if that were the case.

At this stage, a few percentage points a year is solid progress. Sometimes you’ll stall—weeks, months, maybe longer—before you break through.

Often, the trick isn’t “more miles” but different work: speed sessions, strength training, or switching focus.

I’ve had athletes plateau in the half marathon, then shock themselves with a huge 5K PR that eventually carried back into their longer races.

I’ve written an article that discusses this challenge in detail. Check it out here.


What’s Realistic in a Year?

It depends where you’re starting.

  • Brand new runner: Taking 10 minutes off your 5K or 30 minutes off your half marathon in a year is very possible with real training.
  • Intermediate runner: Think 5% improvement in a year if you add mileage or quality.
  • Advanced runner: Even 2% is huge. Cutting three minutes off a 42 minutes 10K is big-time at that level.

Rule of thumb: the faster you already are, the smaller the gains. Also, longer races give you more room to improve. A 5K specialist may have maxed out there, but might crush a first marathon.

Let me give you one more tip. If you ran a 4:00 marathon off casual training, shooting for 3:45 next year is realistic. If you’re already at 3:10 after serious training, don’t expect 2:55 in a year—that’s too steep. Aim for 3:05, chip away.


Bouncing Back After Injury

Every runner deals with setbacks. The comeback usually has two phases:

  1. Regain: You bounce back to 70–80% fitness fairly quick (thanks to muscle memory and aerobic base). Example: if you were a 50-min 10K runner before injury, you might be running 55-min 10Ks again in just a month or two.
  2. Rebuild: Getting past your old PR? That takes time. Maybe another full cycle.

I’ve been there—it’s brutal to know you used to be faster.

But patience pays off.

A lot of runners come back stronger after injury because they’re forced to fix weaknesses (strength training, better recovery).


Red Flags of Overtraining

Biggest trap? Thinking “more is always better.” It’s not.

Warning signs:

  • Dead legs every day, even after rest.
  • Paces that used to feel easy now feel like death.
  • High resting heart rate.
  • Always tired, cranky, or getting sick.

If that’s you, you’re not getting fitter—you’re digging a hole.

Remember, fitness builds during recovery, not while you’re beating yourself into the ground. There’s a saying I love: better to be 5% undertrained than 1% overtrained on race day.


Recovery & Training Age

Your recovery ability matters just as much as your mileage.

A 22-year-old might bounce back from back-to-back hard days.

A 50-year-old? Not so much. That doesn’t mean improvement stops—it just means progress looks different.

Sometimes the breakthrough isn’t training harder, but resting harder.

I’ve seen runners smash a PR after an unplanned lighter training block because life forced them to back off.

You don’t always need more; sometimes you need less.


Training Plans To Help You Beat the Average

So you’re fired up and ready to put in the work?

Good.

Here’s the truth—you don’t need to be a pro logging 100-mile weeks to see real improvements.

You just need a plan you’ll actually follow.

With smart training, even 3–4 runs a week can drop your times faster than you think.

Building Your Training Blocks

Most training plans—whether for a 5K or a full marathon—are built on a mix of easy runs, long runs, and faster workouts.

Nothing fancy. For example, if you’re trying to go from a 35-minute 5K to under 30, a simple 8–12 week block might look like this:

  • 3 runs per week (say Tuesday, Thursday, Saturday).
  • One interval day (something like 1-minute hard, 2-minutes easy, gradually adding more reps).
  • One tempo run—20–30 minutes at that “comfortably hard” pace.
  • One long easy run, building from 2 miles up to 4–5 miles.

That mix is gold. It builds speed, it builds endurance, and it works if you stick with it.

I’ve had runners follow a setup like this and slice minutes off their 5K times without living at the track.

For longer races (10K, half, full), it’s the same principle—just stretched out.

For example, a half-marathoner aiming to break 2 hours might spend 12 weeks running 4 days a week: speed or hills on Tuesday, a midweek run, a tempo run at goal pace, and a Sunday long run building up to 12–13 miles.

Weekly mileage? Maybe 20–25. Trust me, that’s plenty if you’re training with purpose.

Running 2–4 Days a Week: Yes, It Works

Here’s the good news: you don’t have to run every day.

A “Run Less, Run Faster” approach—3 purposeful runs (speed, tempo, long) plus cross-training—is enough for a lot of busy adults.

If you can only run twice a week, you’ll still see gains with one track workout and one long run, especially if you bike, swim, or hit the gym in between.

But here’s the kicker: consistency beats mileage.

I’ve coached runners hitting 6 days a week who stall out, while others running just 3 focused days crush their PRs. If you’re short on time, do less but make it count.

How Much Training Time You Actually Need

Let’s break it down:

  • 5K finish or improvement: 3 runs/week, 20–30 minutes each. About 2–3 total hours including warm-ups.
  • 10K: Build to 4–5 miles per run. 3–4 hours a week.
  • Half marathon: 4 runs/week, long run hitting 10+ miles. Peak at 20–30 weekly miles. About 4–6 hours.
  • Marathon: 4–5 runs/week, long run up to 18–20 miles, peak 30–50 miles. Roughly 6–8+ hours a week.

Yes, marathon training is a lifestyle—it’ll eat up a couple months of your life. But if you want it, it’s worth it.

Training For Specific Time Goals

Want to break 25 minutes in the 5K? Sub-60 for the 10K? Sub-2 half? Sub-4 marathon?

Your training has to match the paces. For example:

  • Sub-60 10K (9:39/mile): train some miles at 9:00–9:30 pace so race pace feels easier.
  • Sub-4 marathon (9:09/mile): include long-run segments and tempos at ~9:00 pace so your body learns to hold it.

That’s how you turn “average” times into PR-smashing runs.

The Truth About Mileage

There’s an old saying: “More miles, more speed.” True…to a point.

But piling on mileage isn’t the secret weapon you think it is.

I hate to sound like a broken but I’ve seen runners hammer 6 days a week, 70 miles total, and plateau. Meanwhile, others run 3–4 days with intent and crush their PRs.

The lesson? Train smarter, not just harder.

Progress comes from pushing your limits, but also respecting recovery. Injuries, burnout, and sickness ruin more seasons than lack of mileage ever will.

Your goal isn’t to run like Eliud Kipchoge—it’s to be faster than the runner you were yesterday.

That’s the real win.

Trust the process, keep stringing together training cycles, and one day you’ll wake up and realize you’ve blown past the times you once thought were out of reach.


Gender Differences in Performance

Alright, let’s get real about this: on paper, men have the upper hand in most standard races.

Bigger hearts, higher VO₂ max, more testosterone—basically more muscle, more hemoglobin, more horsepower.

According to Research, that’s why in your typical 5K or 10K, men come out about 10–20% faster. You see it in the records: the men’s 10K is around 26:24, while the women’s sits near 29:14.

That’s roughly a 10% gap.

Add in the lower body fat percentage—elite guys are about 6–10%, elite women 12–18%—and the extra fast-twitch fibers for bursts of speed, and it’s no shock men dominate shorter stuff.

But here’s where it gets interesting—stretch the distance way out, and the story changes.

In marathons, men still run about 10% quicker. Push to 50 miles? That gap shrinks to 5–6%. Go 100 miles or more?

The Metabolism Advantage

Women’s bodies are simply better at burning fat for fuel. Research shows they can oxidize fat up to 50% more efficiently than men during endurance events.

Estrogen plays a big role here—it protects glycogen stores and nudges the body to dip into fat reserves.

Translation? In ultras, where “bonking” from carb depletion can wreck you, women can keep rolling while guys hit the wall harder.

Muscle Endurance & Fatigue Resistance

Here’s another card women play: more slow-twitch fibers.

Those Type I fibers don’t fatigue as quickly and are built for grinding it out. Studies show women accumulate less lactate and even experience less neuromuscular fatigue at the same intensity.

Even their diaphragm—the main breathing muscle—fatigues less.

This is why women can hold a steady effort deep into a race while men’s engines start sputtering.

Mental Grit & Smarter Pacing

Ultras aren’t just physical—they’re a mind game.

And here’s where women often outsmart us guys. Studies have found men are more likely to go out too hot and blow up, while women pace evenly and stay steady.

Add in what some call a different relationship with pain (childbirth probably has something to do with that), and you’ve got a recipe for durability.

I’ve seen it firsthand: in ultras, men race each other early, flame out, and then women reel them in one by one.

Hormonal Edge & Body Composition

Estrogen doesn’t just help with fat-burning; it also reduces muscle damage and inflammation mid-event, which means better recovery as the race drags on.

And while carrying extra body fat is usually a disadvantage in short races, in ultras—or in channel swims through icy water—it can actually be helpful for insulation and energy reserves.

That’s why women often dominate in endurance swimming events.

Real-World Proof

Want names? Courtney Dauwalter—queen of the mountains, winner of Moab 240 outright.

Pam Reed—two-time Badwater champ in Death Valley, beating all the men.

Camille Herron—24-hour world record holder, clocking 262 km, a distance that outpaces the majority of male competitors.

Even in marathon swimming, women frequently beat men thanks to fat utilization, pacing, and raw toughness.

These aren’t just feel-good stories—they’re evidence of a shift when the distance goes long.


What This Means for You

If you’re a female runner, don’t ever sell yourself short.

Your physiology is built for the long haul. You might not outkick the guys in a 5K, but in an ultra, your endurance engine is elite.

If you’re a male runner, take notes: pacing discipline and patience are lessons worth stealing.

The “fly and die” strategy might get you glory at mile 5, but it’s not the path to your next PR.

And here’s the cool part—mixed fields push everyone.

Women running among men in ultras often get pulled to faster times. That competition sharpens both sides and keeps narrowing the gap.

So let’s end with this: men may have the raw speed, but women have the staying power.

The longer the race, the closer it gets to a fair fight. In some cases, women win outright.

And if that doesn’t light a fire under you, nothing will.


Why Running Gets Better With Age (Up to a Point)

A lot of people think running is only for the young—that once you hit 40, it’s all downhill.

Nope.

That’s a myth.

Sure, raw speed and recovery time slow with age, but endurance, patience, and grit?

Those often increase.

In fact, plenty of runners crush some of their best races in their 40s and even 50s.

Let’s break down what’s really going on with this so-called “Master’s curve.”

The Master’s Curve—When the Drop-Off Really Starts

Science says aerobic capacity peaks in your late 20s or early 30s.

After that, it does dip—but slowly at first. We’re talking around 1% a year between ages 35 and 50.

One study even pegged VO2 max decline at about 10% between 35 and 55. Not the end of the world.

Real-world racing data backs it up.

Marathon records are basically flat from age 18 all the way through age 50.

That means many of us are still close to our peak into midlife. The sharper drop doesn’t usually hit until the 60s or 70s, and even then, some athletes keep performing at crazy levels.

Here’s a stat that blew my mind: a study on Boston Marathon qualifiers found that a well-trained 60-year-old could grade out almost the same as a 19-year-old when you factor in age.

That means, adjusted for age, a seasoned 60-year-old can be just as good as a college kid. Sure, the clock time is slower, but the performance is still top-notch.

And let’s talk outliers: the men’s marathon world record for a 50-year-old? Around 2:19. For a 70-year-old? About 2:54. That’s a 6:40 mile pace—at seventy. Makes you rethink what “old” really means in this sport.

When I hit my mid-30s, I expected the wheels to fall off.

They didn’t.

I’ve seen guys in their 40s and 50s hang right with their younger selves—sometimes even outperform them because they’ve got decades of smart training under their belt.

Why 40–60 Can Be Your Sweet Spot

Here’s the thing: running rewards consistency and patience.

And by the time you’re in your 40s or 50s, you’ve had time to build both.

  • The Mileage Engine: If you’ve been stacking miles for years, your aerobic base is rock-solid. A 50-year-old with decades of steady running often outperforms a younger runner who just piled on mileage last year. Endurance compounds.
  • Training Smarter: Youth makes you reckless. Older runners learn pacing, recovery, and injury prevention the hard way. No more sprinting out like a maniac and dying halfway through a race—you learn discipline.
  • More Time (sometimes): Empty nesters or folks with grown kids often discover they suddenly have time to train. Ironically, midlife can be the season when you’re most consistent.
  • Mental Grit: Life toughens you up. Pushing through a tough workout or the pain cave in mile 20 is often easier once you’ve weathered some storms off the road.
  • Muscle Memory: If you ran in high school or college, your body “remembers.” I’ve seen people pick running back up in their 40s and get close to their college PRs within a couple years.

There’s even evolutionary backing here—humans were built for endurance hunting.

Science suggests endurance holds up much better than sprint speed with age.

That’s why sprinters peak in their 20s, but marathon champs like Meb Keflezighi are still winning big at 38.

Adjusting Goals Without Quitting

Now, let’s be real: your absolute peak PR days might be behind you by your mid-50s. That doesn’t mean it’s game over. You just shift the target.

That’s where age-grading comes in.

Maybe you ran a 1:40 half marathon at 30, and now you’re at 1:52 at 60. But age-graded? That’s equal—or even better—performance. And trust me, winning your age group at a race feels just as sweet as setting a lifetime PR.

Some masters runners chase age-group Boston qualifiers.

Others focus on “Masters PRs”—best time since turning 40, or best time this decade. I love that. It keeps the fire alive without setting you up for disappointment by comparing yourself to your 25-year-old self.

And I’ve coached runners who didn’t lace up until they were 60.

A few years later? They were finishing marathons. Improvement is always possible—it just looks different with age.

Staying Fast as the Years Stack Up

If you want to keep your edge past 40, you’ve got to run smart. Here’s what helps:

  • Strength Work: From 40 on, muscle loss (sarcopenia) is real. Two days a week of strength—especially legs and core—can protect your speed and joints.
  • Flexibility: Don’t let stiffness rob your stride. Yoga, stretching, or mobility drills can keep you fluid and injury-free.
  • Recovery Time: You can’t hammer back-to-back hard days anymore. Build in more rest or cross-training. Listen to your body—injuries heal slower now.
  • Nutrition & Recovery Tools: More protein, maybe vitamin D, and don’t skimp on sleep. Masters runners often swear by massage, compression, or even just a good nap.
  • Respect Pain: What you ran through at 25 can sideline you at 50. Treat little aches early. A few easy days now beats six weeks on the couch.
  • Use Experience: By now you know what works. Less junk mileage, more quality. And don’t underestimate mental tricks you’ve picked up over the years—you can outthink younger runners when things get tough.

FAQs: What Runners Ask About Average Times

These are the questions I hear all the time—from running forums, from coaching clients, and even from runners who corner me after a local 5K.

Let’s break them down, no fluff, just straight talk with the stats to back it up.


Q1: “Is 35 minutes for a 5K bad?”

Not at all. A 35:00 5K is actually right around the median finishing time—most races average 36–37 minutes. For women, 35 minutes is often better than average; for men, it’s just a touch slower than average. But here’s the kicker: it’s well within the normal range.

Think about it this way.

If your last 5K was 40 minutes and now you’re at 35, that’s a huge win.

I still remember my first 5K—ugly form, side stitches, and a finish closer to 40 minutes than I’d like to admit.

But cutting that time down felt amazing. Progress matters more than labels.

If you’re brand new, 35 is a solid place to start.

If you’re more experienced, sure, it might feel like an easy jog. Either way, “bad” doesn’t belong here.

Thirty-five minutes already beats about 40–50% of finishers in a typical race.

And trust me, with some consistent training, many runners who start in the 30s can work their way into the 20s.


Q2: “What’s a good time for a 10K if I’m 50?”

First off—respect. You’re running at 50, and that’s already something to be proud of.

Now, let’s put “good” in context. Average 10K times for folks in their 50s look like this:

  • Men: ~56–59 minutes
  • Women: ~1:04–1:07

So if you’re a 50-year-old guy running around 55 minutes, you’re right on average.

Dip under 50 minutes? That’s strong.

For women, 1:05 is average, and anything under an hour is really solid.

Here’s a breakdown of goals I give runners:

  • Beginner: Under 1:10 (men or women).
  • Intermediate: Under 54 (men) / under 1:00 (women).
  • Advanced: Under 45 (men) / under 50 (women). That’s legit fast at 50.

And here’s a cool fact: age grading tells us that a 50-minute 10K at age 50 is equivalent to running about a 45:00 at age 30. That’s solid no matter how you slice it.

So yeah—an hour for a 10K at 50? Absolutely respectable. That’s about 9:40 pace, and plenty of folks half your age would be thrilled to hold that.


Q3: “Will I finish last?”

This is such a common fear. Honestly? Statistically, it’s very unlikely. Most races—unless they’re tiny or full of competitive club runners—have a wide range of paces.

For example: in a 500-person 5K, the last finisher is often over 60 minutes (yep, walking). In half marathons with thousands of runners, the last finishers can be 4+ hours.

So if you’re running a 45-minute 5K or a 2:45 half marathon, you’ll have plenty of company behind you.

Many races even have sweeper vehicles or “last runner escorts” so no one crosses alone. Some events have volunteers who choose to finish last, just so you don’t feel singled out.

And hey—someone has to be last.

But you know what? That person still beat everyone who didn’t toe the line. I’ve seen last finishers get the loudest cheers. People love cheering for grit.


Q4: “Should I run faster on road vs trail?”

Quick answer: road = faster. Trail = slower. Always.

Trail running isn’t about pace; it’s about effort. Terrain, hills, rocks, and switchbacks all slow you down. You might run 5:00/km downhill and 9:00/km uphill on the same course—and that’s fine. The trail decides your speed, not your watch.

When I switched from mostly road training to trails, I had to check my ego at the trailhead.

My road 5K PR pace? Forget it.

On trails, effort trumps numbers. Sometimes that means hiking the steep climbs while still working harder than a road tempo run.

If your goal is a road race, keep some of your speed workouts on the road or track.

If you’re aiming for trail races, spend time on the trails so your body learns the terrain.

Both complement each other—trails build strength and toughness that make you faster when you get back to the roads.

So yeah, don’t compare trail times to road times.

A 25:00 road 5K might feel like 30:00 on a trail. Both are solid. Both count. And trails? They’ll remind you why you fell in love with running in the first place.

  • “Is a 4-hour marathon respectable?” Absolutely. Faster than average (~4:30). For some older age groups, that’s even Boston-qualifier territory.
  • “How common is a sub-20 5K?” Rare. Less than ~5% of all runners, mostly young guys. If you’re there, you’re flying.
  • “Am I a real runner if I’m slow?” 100%. If you run, you’re a runner. Period. Pace doesn’t define you.
  • “Do trail races count for PRs?” Not really. Keep separate road vs trail PRs. Apples and oranges.
  • “Will I get faster if I lose weight?” Sometimes. Dropping excess fat can help, but training is the bigger driver. And losing too much muscle? That’ll backfire.

 

Final Words – You’re Not Just a Number on a Chart

We’ve covered a ton of ground—mile times, training tips, what age and gender mean for your running.

By now, you probably have a pretty good sense of where you stand and where you want to go.

But here’s the truth I want to leave you with: you are not a stat. You are not a finish time. You’re a runner chasing your own goals, for your own reasons.

Those numbers—percentiles, averages, PR charts—they’re tools. They’re not a judge, jury, or executioner. Don’t let them weigh you down. Use them like mile markers on a long run: they show you where you are, and maybe hint at where you could head next. That’s it.

Say you’re sitting at the 60th percentile for a 10K. Sweet—you’re above average. Why not shoot for the 70th? Or maybe you’re down in the 30th percentile. No shame in that—honestly, that’s exciting, because you’ve got tons of room to grow. Stick with it a year and you might be in the 50th. That’s progress.

And here’s the thing: a PR means more than any percentile. Beating your own best time—that’s the real magic. I’ll never forget the day I ran a full mile without walking.

I felt like I had just broken a world record. Years later, dropping under seven minutes for a mile felt just as good.

The rush of knowing you got better—that’s where the pride lives, not in comparing yourself to strangers on a chart.

Think about it: only one person “wins” a race. But thousands walk away with PRs. That’s why running is so addictive and rewarding. It’s about chasing your next best self, not somebody else’s numbers.

And listen—don’t get hung up on averages.

The “average runner” isn’t a real person. It’s just math on a page. Maybe the “average” marathon time is 4:30.

Who cares?

If you went from 6:00 to 5:00, that’s a massive win. That progress means more than shaving 5 minutes off an already fast time.

Context is everything. Effort, grit, and persistence define you—not where you sit on a chart.

One last thing: running is supposed to be fun. Yeah, it hurts sometimes.

Yeah, goals can push you.

But don’t let the clock steal your joy. If you’re stressing about whether you’re “too slow,” stop and remember why you started. For me, it was about clearing my head, getting fitter, and feeling alive. I bet it’s the same for you.

At the end of the day, finish times don’t capture the best parts of running: the friendships you make on group runs, the pride of sticking to your training, or the courage it takes just to show up at the start line.

Those are the things that matter. So whatever your race time, wear it like a badge of honor.

Celebrate it. You earned every second. And remember, only a small slice of people in this world are even willing to toe the line. That makes you special already.

Like the old saying goes: Dead last is better than did not finish. And did not finish is still better than did not start. So don’t chase averages. Chase your next finish line.

Chase your next breakthrough. And when you cross it—whether smiling or grimacing—know you gave it your best. That’s what really counts.
