Let’s talk about the comparison trap. Because it’s real.
You finish a race proud. You feel strong. Then you open Instagram. Or Strava. Or some results page. And suddenly your time doesn’t feel so good anymore.
I’ve coached women who ran 4:50 and apologized for it.
Apologized.
4:50 is basically average for women in large global races — and yet they felt embarrassed. Why? Because they were comparing upward. Always upward.
I’ve had women ask me, “Should I aim for 4:15? That’s around what a lot of men run.”
And I have to explain — men’s averages are different. The overall average marathon time skews because men and women are different physiologically. That’s not weakness. It’s biology.
Women typically have lower hemoglobin levels. Smaller hearts on average. Different muscle distribution. That affects raw speed potential.
But that’s only part of the story.
Training history matters more. Consistency matters more. Stress matters more. Sleep matters more.
I’ve seen women beat themselves up for things that had nothing to do with talent and everything to do with life load.
Then there’s the motherhood fear.
“If I take two years off to have a baby, am I starting from zero?”
I’ve heard that so many times.
And no — you’re not erased. You’re not deleted as a runner.
But the self-doubt creeps in anyway.
I lurk in Reddit threads sometimes. I see posts like, “I feel so slow, I ran 4:50.”
And I just want to comment, “That is average. You are literally in the middle of the data.”
But comparison messes with perception. Especially when Strava clubs only highlight the top 5% of runners. If you’re constantly staring at the fastest women in the group, of course you’ll feel behind.
You’re comparing yourself to outliers.
And that’s brutal on confidence.
I coached a woman in her late 30s. Two kids. Years away from running. She was convinced she’d take six hours and be last.
She almost didn’t sign up because of that fear.
Race day came.
She ran 4:48.
Right in the middle of the bell curve.
She wasn’t last. Not even close.
The look on her face at the finish — it wasn’t about time. It was relief. Like she had been carrying this secret shame for months that didn’t even belong to her.
The problem wasn’t her fitness.
It was her idea of what was “acceptable.”
And that’s the part no training plan ever addresses.
We don’t usually need to fix women’s legs.
We need to fix the story they’re telling themselves about those legs.
SECTION: Science & Physiology
Alright. Let’s nerd out for a minute.
I’m a coach, yeah. But I’m also the kind of person who reads research papers at night and then texts friends about VO₂ max like it’s gossip. When I first started wondering why women’s marathon times land where they do, I went digging. And the science is actually fascinating — but I promise I’ll keep this human.
Average Finish Times by Gender
Let’s start simple.
Large global datasets show the worldwide average marathon time for women is about 4 hours 45 minutes, compared to about 4 hours 15 minutes for men PR Run & Walk.
So yeah. Roughly a 30-minute gap.
That works out to about 10–12% difference on average. It’s real. It’s measurable. But it’s not massive either. It’s not like women are finishing hours behind.
And remember — averages are messy. They include first-timers, walkers, competitive runners, charity joggers, everyone. But it gives us a baseline.
If the “average guy” runs 4:15, the “average woman” runs 4:45.
That’s normal. That’s data. Not opinion.
VO₂ Max and Oxygen Delivery
Now we get into engine size.
VO₂ max — which is basically how much oxygen your body can use at max effort — tends to be about 10–20% lower in women compared to men, even when both are equally trained PubMed Central.
Why?
Smaller hearts on average.
Less blood pumped per beat.
Lower hemoglobin levels — which means slightly less oxygen carried to working muscles.
So yeah. The oxygen engine is typically a bit smaller.
If you look at elite numbers, an elite female marathoner might have a VO₂ max around 70 ml/kg/min. An elite male might be 80+. That gap shows up in pace potential.
But here’s the part people forget:
Marathons aren’t run at VO₂ max.
They’re run well below it.
And once you’re below max effort, efficiency and pacing and fueling start mattering a lot more than raw engine size.
I’ve coached women with “average” lab numbers who outran people with better physiological stats simply because they trained consistently and paced smart.
VO₂ max sets a ceiling.
But how close you run to that ceiling for 26.2 miles? That’s where experience kicks in.
Running Economy & Pacing
This is where women quietly shine.
Race data — and even published analysis — has shown that women pace more evenly than men over 26.2 miles PLOS ONE The Guardian.
Translation?
Women are less likely to go out like rockets and implode at mile 20.
Part of it might be psychology. Ego management. Patience. Whatever you want to call it.
But part of it is physiological too.
Women’s muscles tend to burn a slightly higher percentage of fat at marathon effort compared to men The Guardian.
That matters because glycogen — stored carbohydrate — is limited. When it runs out, hello wall.
If you’re sparing glycogen by burning more fat, you delay that crash.
I’ve seen it in real races.
I can’t always match the early speed of some guys around me. But by mile 22? I’ve passed a lot of them while they’re unraveling.
It’s not magic. It’s pacing and fuel use.
And here’s something else: the gap between men and women narrows in ultra-endurance events. In some extreme-distance races, women even outperform men. A lot of people think that’s tied to pacing discipline and fuel utilization differences.
There’s something quietly powerful about steady.
Heat & Thermoregulation
This one surprised me when I first read about it.
Women generally have a higher surface-area-to-mass ratio. Which basically means we may dissipate heat a bit more efficiently in certain conditions The Guardian.
Now, heat crushes everyone. Let’s not pretend otherwise.
But I train in tropical humidity. I’ve raced in weather that felt like running inside a sauna.
And I’ve absolutely seen guys who blasted the first half reduced to walking by mile 22, while women who stayed steady kept moving.
Heat punishes aggression.
And aggression tends to skew male in racing.
Again — not a rule. Just a pattern.
Fueling Still Matters (Do Not Skip This)
Now don’t misread the fat-burning thing.
Women still need fuel.
Badly.
Because we often start with slightly less total glycogen storage due to smaller muscle mass.
I learned this the hard way.
I once tried to “diet” through marathon training. Thought I could lean out while building mileage.
Terrible idea.
I bonked so hard in one race I questioned my entire life at mile 20.
Now I fuel early. I fuel consistently. I treat calories like equipment.
You don’t get bonus points for under-eating. You get slower.
Menstrual Cycle Factors
This one gets whispered about a lot.
There’s a 2020 meta-analysis that looked at menstrual cycle effects on performance. It found that, on average, performance is only trivially lower in the early menstrual phase compared to other phases PubMed.
Trivially.
Meaning small. Not race-defining.
But — and this matters — responses are individual.
Some women feel awful at certain points in their cycle. Others feel totally normal. Some even feel strong on day one of their period.
I’ve had both.
I’ve raced fast on day one.
I’ve also had training days where I felt like my legs didn’t belong to me.
Hormones can shift hydration, body temperature, recovery slightly. During the luteal phase, core temperature is a bit higher. Hot runs might feel hotter.
But there is no universal rule like “don’t race during X phase.”
My approach — and what I tell athletes — is track your cycle. Notice patterns. Adjust if needed. Don’t assume doom.
Your body is not fragile.
It’s adaptable.
Injury Risk & Energy Deficiency
This part is serious.
Female runners have a higher incidence of stress fractures — about 2 to 3 times higher than males in distance running populations MDedge.
And if a woman’s menstrual cycle has stopped (amenorrhea), stress fracture risk increases even more — 2 to 4 times higher compared to women with normal cycles MDedge.
That’s not minor.
That’s huge.
This ties into what’s called the Female Athlete Triad or RED-S — basically under-eating combined with high training load leading to hormonal disruption and weakened bones.
And I’m not saying this as a textbook thing.
I lost my period once during heavy training.
I brushed it off.
Then I developed shin pain that turned out to be a stress reaction.
That was my wake-up call.
Now I eat like an athlete when I train like one. I lift weights. I protect bone health like it’s gold.
Women can be incredibly durable marathoners.
But durability requires fuel.
The Real Take
So yes — on average, women’s marathon times are a bit slower than men’s. The physiology explains part of that.
But it’s not the whole story.
Women often pace smarter.
Burn fuel differently.
Handle long steady efforts extremely well.
And individual training matters more than sex alone.
I’ve seen women with modest lab numbers outrun men who train sloppily.
I’ve seen experienced 50-year-old women dismantle younger runners who went out too hard.
Biology sets a framework.
But training, patience, and mindset decide how close you get to your potential.
And that’s where the real work happens.
SECTION: Actionable Solutions
So… what can you actually do with all this? Like, cool, women pace steadier, VO₂ max blah blah, averages… but you’re standing in your kitchen at 9pm wondering if you’re supposed to run tomorrow or collapse on the floor and eat cereal.
These are the things I wish somebody had drilled into me early. Not the fancy stuff. The stuff that actually moves the needle for a marathon, whatever “best” means for you.
- Prioritize Training Consistency
There’s this saying that “consistent miles beat occasional miracles.” And I hate that it’s true, but it’s painfully true.
Early on, I was all over the place. One week I’d run 40 miles because I was fired up. Next week I’d run 10 because life exploded or something hurt or I got in my own head. And then I’d wonder why my marathon felt like a dumpster fire at mile 18. Like… dude. What did you expect.
For women, especially if you’re juggling work, kids, family stuff, stress… consistency is annoying because it’s not sexy. But it’s the #1 thing that helps. Not “crazy mileage.” Just… showing up regularly.
I coached a beginner who ran her first marathon in 5:40 (5 hours 40). Her training was kinda random. Some weeks 2 runs. Some weeks 3. Some weeks basically nothing because she was tired or busy or both. For her second try, we didn’t do anything heroic. We just made it repeatable: four days a week, every week, most runs short. Peak mileage barely changed — maybe 35 miles per week instead of 30 — but she stopped disappearing for a week at a time. And she ran 5:05. That’s a 35-minute drop, mostly because her body finally got the steady rhythm of stress → recover → adapt.
And that’s the thing people miss: your body likes patterns. It likes the same little nudge again and again. Not one monster week followed by a crater.
As a coach I’d rather have someone run 25 miles every week for 10 straight weeks than bounce between 40-mile weeks and zero-mile weeks because they burned out or got hurt. Consistency also tends to sneak-improve running economy and fatigue resistance. Not overnight. But it shows up late in the race, when your legs are trying to quit.
For me now, a “standard” week might be 5 runs totaling 30–35 miles when I’m not peaking, and maybe 40–45 at peak for a marathon. Nothing extreme. But the mileage stays in a reasonable window most weeks, with cutback weeks when I need them. The payoff is I’m not constantly restarting like a beginner again.
- Strength Training & Injury Prevention
I avoided strength training like it was a parking ticket.
I told myself the usual stuff: “I’m a runner. I don’t lift.” Or “I’ll get bulky.” Or “I don’t have time.” And honestly… I was just intimidated. That was the real reason.
Big mistake. Especially for women, strength work is a game changer for two boring reasons that matter a lot: performance and staying unbroken.
Performance: stronger legs + stronger core = better running economy. You waste less energy each step. You hold form longer when tired. Even in a marathon, that matters. You don’t need “speed” to benefit from strength — you need to not fold at mile 22.
Injury side: women often have some built-in biomechanical stuff going on — wider hips, knee angles, the whole runner’s knee circus. Plus the bone density / energy availability piece we talked about earlier. Strength work helps there too. It’s muscle, tendon, bone… all of it getting tougher.
When I finally did it consistently — twice a week, 30–45 minutes — it was almost annoying how much it helped. My nagging IT band pain faded. My hips and knees stopped complaining on long runs. And I got faster without adding any extra running mileage.
One marathon cycle, I added heavy squats, lunges, and core work. I dropped about 15 minutes off my finish time. Was it only the lifting? Probably not. But it helped me hold pace late because my form didn’t fall apart as hard.
I see this pattern a lot: weak glutes and weak core show up as… everything. Shin splints. Lower back pain. Knee ache. Random calf strains. It’s like the body starts leaking stress into the next weak link.
Even if weights scare you, bodyweight helps. Yoga helps. Bands help. One woman I worked with had recurring calf strains; we added calf raises and single-leg balance work and she’s been fine since. Another had hip pain that wouldn’t quit — glute bridges and clamshells (yes, boring) made a huge difference.
And it’s not just “coach vibes.” Studies show strength training improves running economy — meaning you use less oxygen at the same pace. You get “faster” without more cardio. That’s real.
So yeah. If you’re a woman training for a marathon: do strength. Even 20 minutes twice a week. Build the chassis that holds the engine.
Also… as we get older (I’m in my 40s now), keeping muscle matters for health in general. So it’s not wasted effort.
- Nutrition and Iron — Fuel the Engine
I’m gonna be blunt: nutrition can make or break women’s marathon training.
Day-to-day nutrition and race fueling. Both.
Let’s start with iron. Women are at higher risk for iron deficiency. Low iron will wreck your running. It’s not “you’re weak.” It’s “your blood can’t do its job.”
I’ve been there.
A few years ago I felt exhausted for no good reason. Runs that should’ve been easy felt like I was dragging a fridge. I got labs. My ferritin was down at anemic levels. After iron supplements and adjusting my diet (more red meat, leafy greens, vitamin C to help absorption), my energy came back… and my pace per mile dropped by about a minute at the same effort. It felt like someone removed a sandbag from my shoulders.
So yeah — if you’re unusually tired, or your performance is stuck and it feels weird, get ferritin and hemoglobin checked. I tell women this constantly. And not just iron — thyroid issues happen too. Sometimes “I’m slow” isn’t a motivation problem. Sometimes it’s a biology problem.
I’ve seen it in the wild too. I followed a runner in r/C25K who kept “hitting the wall” in training and felt awful. People urged her to check iron. She did. Very anemic. Fixed it and improved her marathon time by 25 minutes. That’s not magic training. That’s basic health.
Now race nutrition: eat, eat, eat when you’re training for a marathon. This isn’t the time for harsh calorie cuts or “I’ll just be disciplined.” So many women undereat without realizing it — diet culture, busy life, appetite weirdness from training, stress… whatever. Marathon training burns a lot. If you’re always in a deficit, you’ll feel sluggish and your injury risk climbs. And sometimes your body holds weight anyway because it thinks you’re in a famine. That’s a fun little bonus.
I keep it simple: protein after runs, carbs overall to keep glycogen topped up. And during long runs + race day, you practice fueling early and often.
For me, I aim for ~40–60 grams of carbs per hour in a marathon. Usually a gel every 30–40 minutes plus sports drink or gummies. Some smaller women do a bit less. But the general ~30–60g carbs/hour guidance applies to us too. Don’t do the “I’m not a 200-lb man so I don’t need fuel” thing. You need what you need. And your gut can be trained.
A well-fueled female runner will outperform a calorie-deprived one every time. Like, I’ve seen it over and over. You don’t get tougher by starving.
Hydration + electrolytes too. Maybe women conserve sodium a bit better in some research… cool. In real life, dehydration still wrecks you. I train in Bali heat and humidity. I carry electrolytes on long runs now. It changed everything. I used to think headaches and cramps after long runs were just “normal.” Nope. That was me being under-hydrated and under-salted.
And yes, GI issues. The lovely part. Hormones can make your stomach extra dramatic. Practice breakfast and fueling. I noticed during PMS week I’m more prone to runner’s trots, so I keep food blander and sometimes use Imodium on race morning if it’s that time. Not glamorous. But it can save your whole day.
Bottom line: food is fuel and health. Treat it like equipment.
- Train With Your Physiology (Menstrual Cycle–Aware Training)
This one is specifically for women, and I wish I’d stopped ignoring it sooner.
I spent years pretending my body felt the same every day of the month. Then I’d have a bad workout and I’d beat myself up… and later I’d realize it was the day before my period again. Like clockwork. And I’d still act surprised. Genius.
So no — it’s not “an excuse.” It’s a real variable you can work with.
If you notice patterns — sluggish, achy, low energy during PMS or the first couple period days — you can plan around it. If you can’t plan around it, at least adjust expectations.
One athlete I coach gets hit hard right before her period: bloating, low energy, migraines sometimes. We set that week up as a lighter week. Key long runs or big sessions happen mid-cycle when she usually feels better. Before that, she’d try to force a long run on a bad PMS day, blow up halfway, then feel wrecked and depressed about it. Now she calls it “Turtle week.” And she doesn’t panic about it.
And yeah, some women feel great around ovulation. That can be “Tiger week” for workouts. But again — individual.
Contraceptives can change all of this. Some women feel smoother on the pill, less up-and-down. Others feel worse on certain types. It’s personal. Sometimes it’s worth talking to a doctor if you suspect it’s messing with training.
Cycle-related iron note: we lose iron during menstruation, so iron status can drift. I time blood tests right after my period sometimes for a worst-case reading. And I make a point to eat iron-rich foods around that time. Little things.
The big idea: training plans are not holy books. Swap the hard workout if your body is waving a red flag. If you need to move Tuesday’s session to Thursday because your uterus is staging a protest, move it. The months of consistent training matter more than one day of suffering just to tick a box.
Work with your body. Not against it.
- Race Strategy Tailored for Women’s Strengths
Alright. Race day. This is where people give away 10+ minutes like it’s a donation bin. Not because they’re unfit. Because they get stupid for the first 10K.
And I say that with love because I’ve done it. I’ve watched other people do it. I’ve felt the “wow I feel amazing” lie in mile 2 and believed it like an idiot.
I really do believe a smart race plan can save you 10+ minutes versus just trying to muscle through with vibes and panic. And honestly, women are already set up well for this because we generally pace steadier. So yeah—use that. That’s not a personality trait. That’s an advantage.
The number one mistake I see (and I made it early on) is starting too fast. Adrenaline hits. The crowd surges. Someone next to you is breathing like a dragon and you think, oh, this is the pace now. And suddenly you’re running tomorrow’s problem.
But remember what we talked about: women often have an edge in endurance by not blowing the early miles. So lean into that. Let the dudes sprint off at the gun if they want. Seriously. Let them go.
I often deliberately start a little slower than goal pace for the first 3–4 miles. It feels weird because you’re fresh and your legs are like, let’s party. But holding back is an investment.
Example from me: when I was targeting a 4:00:00 marathon (about 9:09 per mile), I ran mile 1 around 9:30, then kept miles 2–3 around 9:20. I eased into 9:10s and 9:00s after that. Mid-race I was right where I needed to be. And in the last 10K I passed a lot of the people who rocketed past me early. I finished under 4:00 with a slight negative split. That feeling is honestly addictive. Like… you’re tired, but you’re not falling apart, and everyone around you is bargaining with the universe. And you’re still moving.
A more “normal human” example: say you’re aiming for 4:45 (roughly 10:52/mile average). You might run the first half in 2:22–2:23 (around 10:50–11:00 pace), then if you feel good you speed up a little for a ~2:20 second half. If you don’t feel good, even splitting still gets you 4:45. That’s the beauty of it.
But if you blast the first half in 2:15 because you think you “banked time”… yeah. You didn’t bank time. You took a loan. And the interest shows up at mile 20. Men notoriously do this and blow up. Women do it too sometimes, but I’ve seen women stick to a plan more often. So channel that. The marathon really does start at mile 20. Run the first 20 with your head, and the last 6.2 with your heart. I hate how true that line is.
Now fueling and hydration: race day needs to be almost military-precise. Not “I’ll grab something when I feel like it.” That’s how you wake up in mile 23 like, why am I dead.
Women sometimes underestimate their needs. GI fear. Sugar fear. Or just… not realizing how much energy we’re burning even at “easy” marathon effort.
I set a timer on my watch to beep every 40–45 minutes so I take a gel or chews on schedule. Because when fatigue hits, your brain turns into soup. You forget. You delay. And by the time you feel weak or hungry, it’s often too late. So stay ahead of it.
Same with drinking. Sip at every aid station if you can, even a couple gulps, especially in warm weather. Bodies smaller = less margin. You can slide into dehydration faster than a big guy might. What I do: I carry a small bottle early so I can drink when I want, not when the aid station chaos says I’m allowed. Then I toss it when it’s empty and use on-course cups in the second half.
Another strategy point: menstrual cycle stuff. If race day lands on your period or ovulation or whatever your body is doing that month, plan like an adult about it. Pain relievers if you need them. Extra pit stop time if you’ll need it. Clothing choices if you bloat. It sounds small but it reduces morning-of stress.
And lastly—use the even pacing strength as a mental weapon. I literally frame it like: I’m gonna run my own race… and later I’m gonna hunt. It becomes a stupid little game in the final 6 miles: how many people can I pass without blowing myself up. Each pass is a tiny confidence hit. Because you paced evenly, you still have something left while other people are fading.
Women are also weirdly good at working together late in races. I’ve had those miles where you sort of form an unspoken pact with another woman: we’re not slowing down. We’re doing this. No speeches needed. Sometimes you just say, “Let’s keep moving,” and that’s enough.
So yeah—patience, steady pacing, attention to fueling. Those aren’t just “nice traits.” They’re literally a race plan. Execute that and you’ll run faster than if you just hammer recklessly.
SECTION: Coach’s Notebook
I actually keep a physical notebook of running notes and lessons. Yes, I’m a nerd. But also… it saves me from repeating the same mistakes for the 40th time.
Flipping through it, it’s a lot of the same themes again and again—especially with women I coach, and honestly with me too.
- Mistake: Under-fueling (especially copying generic plans).
This one shows up constantly in my notes. Like, constantly.
One athlete bonked in two straight marathons around mile 20. Training was decent. Mindset was decent. But she kept detonating late. We looked at her nutrition and realized she was following a carb plan built by a 180-pound male coach. It had her at about 150–200 calories/hour. For her (~120 lbs), that wasn’t terrible on paper, but in hot weather and with her gut tolerances, she needed more.
We adjusted her to ~250 cal/hour, spaced as 60–70 calories every 15 minutes or so using gels and Gatorade. Boom. No wall in her next race. Finished strong and cut 20 minutes.
The lesson isn’t “everyone needs 250.” The lesson is one size doesn’t fit all. A lot of women under-fuel because they think “that’s how guys do it” or they’re scared of stomach issues. You might need to tweak amount, fuel type, timing. And you test it. You don’t just copy someone’s Instagram plan and pray.
- Mistake: Ignoring health signs (iron, etc.).
My notebook has stuff like: “E. sluggish → told her to get bloodwork → anemic.” And it’s… way too common.
Women write off extreme fatigue as “I’m not tough enough” when it’s literally fixable. I did it too. So a rule in my coaching: if someone has an unexplained performance nosedive, we look under the hood. Iron, thyroid, B12, Vitamin D, whatever. I’ve had multiple women come back with low ferritin or full anemia. Once treated, it’s night and day. Different runner. Like someone swapped their legs out.
So if you’re dragging and it feels off, don’t just blame character. Check the basics.
- Mistake: The “vanity long run” (too fast, too hard).
Oh man. I have pages of this.
Early on I’d run long runs way too fast because I wanted the ego boost. “I did 20 miles near goal pace!” Or I’d chase someone in a group run. And then I’d be wrecked for days. Or I’d tweak something. Or I’d limp into race day with some stupid injury I earned for no reason.
One cycle I pushed a 20-miler at race effort on a whim and ended up with IT band pain for weeks. Started the race with my knee taped and angry. Miserable day.
Now I treat long runs as training, not testing. Most of mine are at least 60–90 seconds per mile slower than marathon pace. Sometimes slower, especially in heat. And I race better because of it. I literally wrote in my notebook: DON’T RACE THE LONG RUNS. SAVE IT FOR RACE DAY. It’s underlined twice like I was yelling at myself.
If you want to prove fitness, do a controlled workout—like 12 miles easy + 8 at marathon pace. Don’t empty the tank in training just to feel brave.
- Observation: Women and rest—usually a good combo.
I’ve noticed a lot of women are actually better at taking rest days than the guys. Not always, but often. More patience, less ego stuff. They’ll do the recovery jog actually easy. They’ll actually take the day off when it’s prescribed.
Men… a lot of them hate resting. They want to “earn” every day. And they end up boom-and-bust.
So if you’re a woman with Type-A overtraining tendencies (hi), learn this: rest is not weakness. It’s part of training. I schedule at least one full rest day each week, sometimes two if life is chaos or my body is cranky. And during taper I actually taper now. I used to sneak extra miles because I was nervous. That backfired and left me flat on race day. Now I lean into taper: sleep, light jogs, let the work sit.
- Observation: Women’s pacing and decision-making.
This matches the research you cited earlier—women pace more evenly and make smarter decisions mid-race. I see it constantly.
I coached a husband and wife for their first marathon. I gave them the same advice. Husband ignored it and went out like it was a 10K. Hit the wall at mile 18. Suffered the rest of the way. Wife stuck to the plan, ran an even split, and had energy to kick at the finish. She beat him by a few minutes. He admitted afterward he wished he’d listened.
So ladies—trust that instinct. Don’t get sucked into someone else’s pace.
- Turning point: Hydration in heat.
Notebook entry: runner kept cramping in the last 10K. Training solid. But heat destroyed her.
We realized she wasn’t drinking enough and wasn’t taking salt. She’d come back from runs with salt dried on her skin. For a humid marathon we created a strict plan: drink to thirst plus a little extra at every station, carry a bottle early, electrolyte capsules at hour 2 and 3.
She went from 5:10 PB to 4:38. No cramps. Negative split. She emailed me after and wrote in all caps: HYDRATION WAS THE KEY. That stuck with me. Especially for women who sometimes underrate sweat loss (“I don’t sweat that much”—yeah, okay).
- Turning point: Fueling and the sub-4 breakthrough.
Another one I love: woman ran 4:05–4:07 three marathons in a row. Always slowed late. She was tiny (about 100 lbs) and only took maybe 3 gels total because she assumed she didn’t need more.
We changed it: 5 gels (one every 30 min after 1 hour) plus sports drink in between. Also bigger breakfast (she was basically nibbling toast before). We added strength too, but fueling was the big change.
Next marathon: 3:58. Strong finish. Jumped at the line and almost cried when she saw 3xx on the clock. In my notes I wrote: “Fueling = success. Finally got her to take 5 gels.” Because that’s the thing—so many women are hesitant to take in “too much sugar.” Meanwhile they’re dying at mile 23. Take the gel.
- My personal faceplant at mile 21 (breakfast-skipping stupidity).
Yep. I have this burned into my memory.
I woke up late before a long run. Had coffee. Skipped breakfast. Thought, “I’ve got gels, I’ll be fine.” Famous last words.
By mile 17 I was empty. By mile 21 I was dizzy and sitting on a curb like a cartoon. Then—because I’m stubborn—I also started a marathon a few weeks later without a real breakfast because I was nervous and couldn’t eat much. Mile 21 again: lights shutting off. I didn’t collapse, but I crawled the last 5 miles and lost 10–12 minutes I absolutely could’ve saved.
My notebook after that literally says: EAT BREAKFAST, YOU FOOL.
Now I wake up early enough to eat 300–400 calories 2–3 hours before the race. Bagel, oatmeal, whatever sits. Then a little snack 30 minutes before (half banana, small carb thing). Especially for women—smaller body, less glycogen stored—starting topped up matters. If solid food is hard, do something liquid. But get the calories in.
Those are just some entries. But the pattern is clear: training science matters, sure. But execution and listening to your body matter just as much. And mistakes repeat until you make them expensive enough that you finally stop. I still write notes after races because even a decade into this, I’m still learning what my body tolerates and what it punishes.

One thing that’s kept me sane in this whole marathon thing is other runners. Like… genuinely. Especially other women runners who just say the quiet stuff out loud. The doubts. The messy parts. The “I’m proud but I’m also kinda embarrassed and I don’t know why” part. You hear enough of that and you go, oh… okay. I’m not broken. I’m just human.
Here are a few voices (paraphrased for privacy) that have stuck with me and honestly… they’re basically the same conversation in different accents:
- First-time marathoner: “I walked half of my first marathon and still finished in 5:12 — proudest day of my life.”
I love this one because it flips the whole shame script. She didn’t apologize for walking. She didn’t apologize for being over 5 hours. She was just proud. Like, proud-proud. And yeah—26.2 miles doesn’t care how you cover it. Running, walking, shuffling, bargaining with God… it’s still a marathon. Her joy jumped off the screen. I remember reading it and smiling like an idiot for days. - Another woman: “I used to think a 5-hour marathon meant I was slow… turns out most women in my race ran around 4:45–5:15. I was literally average. Once I learned that, I felt a lot better.”
This is the comparison trap in a nutshell. She was comparing herself to some imaginary standard—maybe Boston posts, maybe some elite highlight reel, maybe that one friend who’s freakishly fast. Then she actually looked at the race results and went, oh. I’m not some outlier. I’m just… in the middle. And sometimes that’s all you need. Context. Not motivation quotes. Just context. I tell runners all the time: look up your race stats. Weather, hills, crowd size… it matters. What you thought was “slow” is often just… normal. - Running mom group: “Ran a 4:10 marathon a year after having twins. Hardest thing I’ve ever done, but I did it.”
The comments under those posts are always wild—in the best way. So much support. And yeah, 4:10 is a really good time anytime, but the point isn’t even the number. It’s the context. Twins. Sleep deprivation. The whole life load. That 4:10 might’ve cost her the same suffering as someone else’s 3:30… or someone else’s 5:30. That’s why time comparisons get weird fast. Women cheering other women for the whole story, not just the clock… that’s one of my favorite things about this community. - Competitive forums (Let’s Run vibes): “Are women naturally slower or is it societal?”
Those threads can get intense. People argue “talent pool and opportunity” vs “physiology differences.” And honestly, I take motivation from it more than anything. Like, it makes me want to train hard and also encourage other women to keep showing up. I’ve watched women’s participation explode over the years, and with more women in the sport, the front end gets deeper, the whole scene gets stronger, and the vibe shifts. We may never erase the gap completely (testosterone is a heck of a drug, yeah), but the bigger win is more women getting on start lines and raising the general level. And supporting each other instead of treating it like a zero-sum leaderboard. - Gear + wardrobe threads (the stuff only women really get):
Sports bras. Chafing. Shorts vs skirts. Compression socks. The never-ending hunt for pockets. I’ve seen threads where a woman basically MacGyvered two bras together mid-race because the chafe was brutal. And then everyone’s in the comments like, “Here’s my anti-chafe stuff,” “Here’s what I stash in my bra,” “Here’s how I tape this,” “Here’s what saved me.”
We laugh about it but it matters. Comfort is performance. If something rubs wrong in training, fix it. Because 26.2 miles will find every weak spot in your clothes. I posted about my own double-bra fiasco (from my first marathon) and got this chorus of “oh girl, same.” It was weirdly comforting. - Lifestyle reality checks:
One woman: “I went from 5:30 to 4:50 by sleeping 8 hours and quitting alcohol for a few months.”
Another: “Work stress was killing me. Changed jobs and boom—energy came back and I dropped 20 minutes.”
That stuff hits because it reminds you training isn’t happening in a bubble. Life leaks into your pace. Stress, sleep, relationships, mental health… it all shows up on race day. Women carry a lot. You hear those stories and you realize: sometimes the “training fix” isn’t another workout. Sometimes it’s boundaries. Sometimes it’s sleep. Sometimes it’s cutting the thing that’s draining you. I’ve made some life adjustments too—especially during peak training—and yeah, it shows up in my times, but more importantly it shows up in my enjoyment.
So yeah. Community. Reddit threads, local clubs, running group chats, global social feeds… it’s a goldmine of perspective. When I feel down about a run, I remember one of these voices, or I message a running friend, and suddenly I’m not alone in my head. Running can feel solo. But you’re never actually solo out there.
SECTION: Skeptic’s Corner
Okay, now the “yeah, but…” section. Because if you’ve been around runners long enough, you know we don’t let anything sit without poking it.
“4:45 average — that’s just a number. What about the huge range?”
Yep. Totally. The average is the middle of a massive spread.
In any marathon you’ll have the fast women finishing around 2.5–3 hours (elite or sub-elite), then a big pack living in the 4–5 hour world (recreational runners), and also plenty of determined humans finishing in 5, 6, even 7+ hours. First-timers, charity runners, people doing it for personal reasons, people juggling ten million life things. All valid.
And the average doesn’t tell you which race was more meaningful. It just tells you where the statistical middle sits. The woman who runs 3:15 probably trained hard for years or has a monster engine or both. The woman who runs 6:15 might be holding her life together with duct tape and still showed up and finished—monumental.
And yeah, someone will always be ahead of you. Someone will always be behind you. If you’re at 4:45, a bunch of people beat you… and a bunch of people finished after you. And even if you’re last (I’ve been near the back of a small race before), you still finished a marathon. That’s not nothing. That’s… ridiculous, actually. In a good way.
“Is it really true women pace better? I know women who blew up too.”
Of course. Women aren’t magically perfect pacers and men aren’t all reckless idiots. These are just group tendencies. That’s it. Over big datasets, women tend to slow down less in the second half, and you’ll see that in studies like the ones people cite from journals.plos.org. But in real life? Individuals are messy. I’ve seen beautifully paced men. I’ve seen women go out too hot and explode. Personality and experience matter a ton.
And yeah, one fair criticism is: maybe more men are chasing ambitious time goals (BQ type stuff) and taking bigger risks, while some women are more focused on finishing, so the pacing difference might be partly psychological or social, not purely physical. I buy that. Probably a mix.
My takeaway isn’t “women are better.” My takeaway is: even pacing usually works. And since women as a group seem to do it more, keep that strength. Use it. Don’t fight it.
“Physiology isn’t everything. What about outliers and other factors?”
Yes. Physiology explains some stuff (VO₂ max differences, muscle mass, hemoglobin, all that). But it doesn’t decide your fate.
There are women who beat most men in marathons because they’re better trained, more experienced, and have the genetics for endurance. Culture matters. Opportunity matters. Safety issues matter. Family load matters. For decades women didn’t have equal access or encouragement in sport. Even now, a lot of women have extra hurdles (time, caretaking, running at weird hours, all of it). So when we talk data, I keep it in my head: real life is messy. This isn’t a lab.
Science is useful. But it’s not the whole story.
“When standard advice doesn’t work…”
I think of a woman I know who did everything “right.” Good plan. Fueling. Sleep. Still stuck around 4:30 for years. Finally discovered mild hypothyroid stuff and also she was sliding into perimenopause—energy and recovery changed on her. She got treatment, adjusted training (more cross-training, more recovery days), and broke through.
That taught me: sometimes the “just train harder” advice isn’t the answer. Sometimes there’s an underlying health thing. Women in their 40s and 50s deal with hormonal shifts that can change how training feels. Might mean more strength, more rest, different nutrition (more protein, etc.). Your body throws curveballs. You adjust. That’s not failure. That’s just… reality.
“Time vs enjoying the run.”
This is the part where I have to check myself too. No one hands you a paycheck for running faster unless you’re elite (and most of us are not). I’ve caught myself getting too obsessed with PR-chasing and then I remember why I started: challenge, stress relief, community, feeling alive.
One of my most enjoyable marathons was one of my slower ones. I ran 5+ hours with a friend doing her first marathon. We high-fived every mile marker, took goofy selfies with spectators, soaked it in. She cried at the finish and thanked me for staying with her. I felt more fulfilled than after some of my faster solo races. That’s in my notebook too, because I need the reminder: faster doesn’t automatically mean better.
I also laugh thinking of a friend who said: “Running a marathon during peak PMS felt like the course was designed by Satan.” She finished way slower than normal and she wears it like a badge of honor. Honestly? That might’ve been tougher than her PR. Different day, different fight.
So yeah. Skeptic’s Corner conclusion: this stuff can’t be boiled down to one number or one factor. Averages and studies give context and help us stop lying to ourselves in the worst way. But each runner’s reality is different. Use the knowledge to feel steadier, not smaller. If some advice doesn’t fit you, fine—find what does. If your time isn’t where you want yet, also fine. You keep showing up, or you shift goals to what actually makes you happy. You’re allowed to run for fun. You’re allowed to run to finish.
And you’re allowed to be proud of your journey without needing it to look impressive on paper.
SECTION: Original Data / Coach’s Log
Okay yeah, this is the part where I turn into a full-on numbers goblin. I can’t help it. I like looking at logs and stats because it calms my brain down. Like, oh, this is what “4:45” actually looks like in real life… not just a scary number on a results page. So here are some reference points I keep coming back to when women ask what marathon times “mean.”
- Paces for Common Finish Times:
I always like translating finish times into pace because it makes it feel less mysterious. Like, “4:45” stops being this vague monster and becomes… “okay, that’s 10:52 per mile.”
So here are a few benchmarks I use a lot:- 4:30 marathon = ~10:18 per mile (about 6:24 per km)
- 4:45 marathon = ~10:52 per mile (about 6:45 per km)
- 5:00 marathon = ~11:27 per mile (about 7:07 per km)
- 5:30 marathon = ~12:35 per mile (about 7:49 per km)
And here’s the thing people don’t really feel until they’ve done it: running ~11:00/mile for a few miles in training might feel totally normal… but doing it for 26.2 miles is the hard part. That’s the marathon. Not the pace itself. The holding.
Also I like using quick mental math in training. If you’re running 5 miles in an hour a lot (that’s 12:00 pace), that’s roughly pointing you toward something like a ~5:15 marathon if you can hold it with proper training and fueling. It’s not perfect, but it’s a decent “where am I at” check.
And it’s wild how small pace differences turn into big time. The difference between 4:30 and 5:00 is only about 69 seconds per mile — sounds small, right? Over 26 miles, it’s not small anymore. It’s a whole mood shift.
- Typical Times by Age Group:
Age matters… but not in the way people think. It’s not like you hit 40 and your legs instantly fall off. It’s usually a gradual drift.
A lot of datasets show that many women in their 20s and 30s land in that 4 to 5-hour range on average.
Then in the 40–49 range, the average is often around 4:45–5:00.
In the 50s, a lot of women are 5+ hours.
And into the 60s and beyond, you’ll see plenty of finishes in the 5.5–6.5 hour zone (and beyond) for many.
But I’m always careful here because averages can mess with your head. I know women in their 50s running sub-4:00 because they’ve been at it forever and they pace like robots (in the best way). And I know women in their 20s running 5:30 because they’re brand new and just trying to survive the distance.
I also mess around with age-grading calculators for fun. It’s not gospel, but it’s a nice way to remind yourself that “good” shifts with age. Like a 50-year-old woman running 5:00 can age-grade to something like an “open age” equivalent around 4:20-ish for a 30-year-old. And yeah, that can be a morale boost when you’re not 25 anymore.
- Heart Rate Zone Example:
I use heart rate in training, mostly to keep myself honest. Because my ego will lie to me. My watch usually won’t.
For me (I’m in my 40s), marathon effort is roughly 75–80% of max heart rate, which lands in what’s often called Zone 3 (moderate). I’ll do long runs sometimes where I sit in that zone to rehearse marathon effort.
And for a lot of runners, especially women who are well-trained, marathon HR drifts up over the race. You might start around ~75% MHR, and by the end you’re flirting with 85–90% just because fatigue is stacking. That’s normal.
But if you’re hitting near 90% in the first few miles? That’s a red flag. You’re either going too fast or the heat is cooking you.
I had a hot marathon once where my HR was literally ~10 bpm higher than normal at the same pace. Same pace, different body. I had to slow down or I was going to end up visiting the medical tent. It became a “finish the thing” day, not a “race it” day. HR helped me accept that before I did something dumb.
- Negative Split and Pacing Data:
Negative splits are rare. Like… really rare. Maybe 1 in 10 marathoners, if that, run the second half faster than the first. It’s hard. Your body doesn’t want to do it.
What’s interesting: in one big dataset, almost 18% of women managed a relatively even or negative split compared to about 14% of men.
Not a massive difference, but it supports that pacing tendency we talked about.
In my own logs? I’ve pulled off a true negative split marathon twice. Twice. And both times felt like magic. Passing people late is this weird psychological drug.
Most of my marathons I’ve slowed down by 2% to 10% in the second half. And yeah, that’s a huge spread. A 10% slowdown for me looked like going out on 4:00 pace and finishing around 4:24. I’ve done it. It sucked. A 2% slowdown is more like starting on 4:10 pace and finishing around 4:15—not perfect, but controlled.
I always tell people: look at your splits after the race. Your splits tell the truth story. If you see a big positive split, ask why. Did you bank time early? Fueling problem? Heat? Ego? You don’t have to beat yourself up—just learn. Over years, my splits have gotten steadier because I got less emotional early and more serious about the boring stuff.
- Calculators and Goal-setting:
I use those “pace for X time” calculators a lot when coaching because it helps people stop guessing. If someone tells me, “I want a 4:30,” I’m like, cool—that’s ~10:20/mile. Then we check if their current 5K/10K/half marathon times make that realistic, and we test bits of it in training.
A rough rule of thumb I use: marathon pace is often about 60–75 seconds per mile slower than half marathon pace, assuming proper training.
So if you run a half at 9:30/mile (around a 2:05 half), add 60–90 seconds and you land in the 10:30–11:00/mile range, which predicts around a 4:35–4:48 marathon. Ballpark.
And yeah, I’ve seen some women convert from half to full really efficiently. Like a woman running a 2:10 half (that’s 9:55/mile) and pulling a 4:30 full (10:18/mile)—only ~23 seconds per mile slower. That’s super efficient endurance. I see it more often in women than men, but again… trends, not rules.
- Slowdown Curves (“Hit the Wall” data):
This stat sticks with me because it’s both comforting and terrifying: about 28% of men and 17% of women “hit the wall” in marathons in a big sample.
And among the people who hit it, men tended to slow down more—the drop was steeper.
I don’t read that as “women are immune.” We’re not. 17% is still a lot of people. I read it as: pacing and maybe fueling habits differ, and if you can avoid a dramatic crash, you’re already ahead of a lot of runners.
I’ve been in that 17% before. It’s miserable. But if it happens, I don’t want you spiraling into shame. You learn from it. Maybe it was nutrition, maybe you went out too fast, maybe it was just a weird day. Next time you correct what you can control.
- Training Mileage vs. Marathon Time:
This is the question everyone asks because we all want a clean formula: “How many miles per week for X time?”
There’s no perfect answer, but there are patterns.- Women running ~4:00–4:30 often peak somewhere around 30–50 miles per week.
- Women in the 3:30–4:00 zone might be more like 40–60 mpw.
- Women running 5:00+ are often in the 20–30 mpw range (or less).
And in my own life? I went from a 5:20 marathon to a 3:58 marathon over years, and my weekly mileage moved from around ~20 mpw (for the 5:20… I was undertrained, no sugarcoating it) up to around ~45 mpw for the sub-4.
But it wasn’t just mileage. It was experience, better workouts, strength training, less stupid pacing, better fueling, the whole package.
I also know people who ran sub-4 on 25 mpw because they’re built different or they came from another endurance sport. And I know people who needed 50+ mpw to break 4:30. So mileage guidelines are a framework, not a law.
And yeah, diminishing returns are real. Going from 20 to 40 mpw can massively change a newer runner. Going from 40 to 60 might help, but usually not as dramatically. Going 60 to 80 is… a different world. Most recreational women don’t need monster mileage. They need consistency and a balanced week they can repeat without snapping in half.
I could keep going forever, but I’ll stop before I become unbearable. The point is: data is a tool. It helps you set goals and diagnose problems. But every number needs context. Your 11:00 pace might be someone else’s hard day and someone else’s warm-up jog. Doesn’t matter. What matters is what it means for you, and what you can repeat week after week without hating your life.
FAQ
Alright, this is the part where I answer the stuff women ask me over and over. And I get it. Because marathon times mess with your head. Like you can feel proud for five minutes… then you see one random result online and suddenly you’re spiraling. So let’s hit the big questions.
Q: Is 5 hours slow for a woman?
A: No. A 5-hour marathon is not “slow” for a woman. It’s… honestly, super normal. Like right there in the normal range.
The global average for women is around 4:45–4:50 prrunandwalk.com marathonhandbook.com, so 5:00 is basically just a little on the slower side of average, but still completely inside the normal finishing range. Especially if it’s your first marathon, or the course is hard, or the weather is gross. Five hours is a legit finish.
And listen—back-of-the-pack runners work just as hard. Sometimes harder, in a weird way, because they’re out there longer. More time under stress. More time negotiating with your brain. More time dealing with the heat, cramps, GI stuff, whatever.
Also context matters a lot. If the race was hot or hilly, 5:00 might actually be above average for that day. Like you can’t compare a cool flat marathon with a humid hilly one and pretend it’s the same thing.
So yeah. Plenty of women finish around five hours. It’s basically the heart of the bell curve. There’s nothing “slow” about covering 26.2 miles.
Q: How do I compare my marathon time fairly?
A: Fair comparison is hard. Like… genuinely hard. Because running isn’t a lab experiment.
If you want the closest thing to “fair,” you’ve gotta account for three things: age, course difficulty, and conditions.
- Age first. Compare within your age group.
If you ran 4:40 at 25, how does that compare to other women in their 20s? (Usually that’s a bit better than average.)
If you ran 4:40 at 55, that’s really strong for that age. Like age-group-award territory in a lot of races.
Age-graded tables can help here. They’re not perfect, but they give you a rough idea of what your time “means” if age is factored in.
- Course + weather second.
Marathon times swing wildly based on the day. A 4:55 on a hot, hilly course might be roughly equivalent effort-wise to a 4:40 on a flat cool course. So if you ran Boston (hills, chaos, weather swings) and your friend ran Berlin (pancake flat, perfect weather), you can’t compare those like they’re the same test. - And honestly… the best comparison is you vs. you.
Are you getting better relative to your past self? That’s the cleanest measurement. If you aren’t improving, there’s usually a reason—less training, injury, stress, sleep falling apart, whatever. But random internet comparisons? That’s usually just pain with no payoff.
And yeah, I know it’s tempting to compare to strangers. I do it too sometimes. Then I catch myself and I’m like, why am I doing this to myself?
Q: Can women follow men’s training plans?
A: Generally… yeah. A solid marathon plan is a solid marathon plan. Long run, easy mileage, some faster work, recovery—those principles work for everybody.
But women might tweak how they run the plan in small ways.
- You might line up harder workouts with the weeks you usually feel better in your cycle.
- You might need more focus on iron-rich foods or just more sleep in certain stretches.
- You might do more strength work than the plan suggests, because bone density and muscle mass stuff is real and it matters.
- And recovery can feel different depending on the type of workout. Some women handle long easy volume fine, but get wrecked by repeated max-intensity sprint stuff (or sometimes it’s the opposite—everyone’s different).
So if a generic plan says “two interval workouts a week” and it’s destroying you, it’s not a moral failure to adjust it. Maybe you drop one of those and replace it with a tempo run or an extra easy day. That’s not “being weak.” That’s staying healthy enough to keep training.
Plenty of women follow plans like Hal Higdon, Jack Daniels, etc. and do great. Those plans don’t always talk about gender at all. The bigger skill is learning when to follow the plan and when to tweak it based on reality—your body, your job, your kids, your sleep, your stress.
Q: Should I adjust my cadence?
A: Cadence is one of those topics that turns into a weird internet religion. Like “180 is the magic number.” And… no. Not like that.
There’s a normal range. Women often naturally have a slightly higher cadence than men at the same pace because, yeah, shorter legs on average = more steps to cover the distance. But I’ve coached women with low cadence and long stride too. Bodies vary.
If your cadence is really low—like under 160 at marathon pace—then yeah, it might be worth looking at. Low cadence can sometimes mean overstriding, and overstriding can waste energy and beat up your joints.
I used to sit around ~164, and over time I nudged it up closer to ~176 with practice and drills and just awareness. It did help me feel smoother. Not like a miracle. More like… fewer “braking” steps. Less clunky.
But if you’re already in a reasonable zone—say 165–180—I wouldn’t obsess. Often you get fitter, you get stronger, you get more relaxed, and cadence changes on its own.
If you want to play with it, do it gently. Like pick a small segment of a run and try quickening your turnover without speeding up (so your stride shortens a little). It will feel weird. It’s supposed to. Some runners use a metronome or BPM music too.
Just don’t make cadence the main project. Big marathon gains usually come from aerobic fitness and endurance. Not whether you’re at 170 or 175 steps per minute.
Q: Does childbirth affect marathon performance?
A: It can. And it can in a lot of different ways.
Pregnancy and childbirth are huge physical events. Hormones shift. Body structure shifts. Joints can be looser. Core and pelvic floor take a hit. Sleep gets wrecked. Time gets stolen. And sometimes you just don’t feel like yourself for a while.
Common postpartum stuff I see:
- weaker core/pelvic floor (sometimes leading to back pain or minor leaking when running—pelvic floor PT can be a lifesaver)
- less time and energy to train
- weird new aches (hips, knees, posture changes)
- just being tired all the time because… baby
So yeah, at first, performance can stall or dip or just go into maintenance mode. That’s normal.
But the other side is: plenty of women come back strong. Some even PR after baby. Sometimes because they become more focused with limited training time. Sometimes because their base comes back faster than they expected. Sometimes because motherhood changes their mindset and they stop wasting energy on nonsense. I’ve seen it.
And there’s the mental side too. After you’ve been through childbirth and newborn life, marathon discomfort can feel… different. Not “easy,” but different. Like the suffering doesn’t scare you as much.
Physiology-wise, lots of women hit strong endurance levels in their 30s anyway, which overlaps with childbearing years, so it’s messy to separate what’s “baby effect” vs “age + experience + smarter training.”
I’ve coached new moms who ran their best times a year or two after giving birth. I’ve also coached moms who struggled to return to pre-pregnancy times—usually because time and recovery were the limiting factors, not “ability.”
The big thing I push is gradual progress. Postpartum marathon shape shouldn’t be rushed. Sometimes it takes a year or more to feel like yourself again. And if you rush it, injuries show up fast.
I’ve seen one friend try a marathon 6 months postpartum. She finished, but it was rough and she admitted she wished she’d waited. Another friend took 18 months to rebuild slowly, then came back and PR’d and felt good doing it. Those are two very different experiences.
Also your priorities might shift. Some women lose competitive drive for a while. Others get more motivated because running becomes “me time.” Both are normal.
So no—childbirth doesn’t put a ceiling on your marathon life. Plenty of women run as fast or faster after kids (even elites like Paula Radcliffe, and Keira D’Amato who broke records post-children). But give yourself grace. Your body changes, your life changes, and it’s okay if you’re not “back” instantly.
Q: What’s a good marathon time for women by age?
A: “Good” is tricky because it depends on your goals. But I know what you mean. You want a rough yardstick. Like, “am I in the normal zone?” or “am I doing better than average?” That kind of thing.
Here are loose benchmarks, using rough averages as a reference. Don’t turn this into a label. Use it like a map, not a judge.
- Women in their 20s: Average is roughly 4:40–4:45. So “good” (meaning better than average) might be under 4:30. Truly excellent (top 5–10%) might be sub-3:30.
- Women in their 30s: Average around 4:45. Running 4:30 or better in your 30s is strong. A lot of women hit PRs in their 30s because experience starts stacking. Sub-4 is a big milestone here.
- Women in their 40s: Average creeps toward 4:50–5:00 by late 40s. So under 4:45 is better than typical. Breaking 4:00 in your 40s is legit impressive and usually comes from consistent training. Also, qualifiers like Boston start adjusting by age (for example: a 45-year-old woman needs ~3:50, while a younger woman needs around 3:30).
- Women in their 50s: Average often lands in the 5+ hour range. So under 5:00 is strong. Plenty of dedicated 50-somethings run in the 4-hour range, but usually they’ve been doing this a long time or they train seriously. And honestly, just finishing a marathon in your 50s is already something most peers aren’t doing.
- 60s and beyond: Averages might be 5.5–6+ hours. A “good” time for most people here is finishing healthy. But there are rare age-group monsters running sub-5, and the occasional 60+ woman in the 4-hour range (usually record-setter types).
And I’ll say it again because people forget: average doesn’t mean “good” and slower than average doesn’t mean “bad.” Good can also mean: you trained, you showed up, you ran the day you had, and you finished.
Use age benchmarks as a reference. Not a verdict. And if you catch yourself using them to beat yourself up… yeah, step back. That’s not what running is for.
Q: Why do women pace more evenly?
A: Yeah, this one’s real. When people look at big marathon datasets, women—on average—tend to slow down less in the second half. That shows up in those big analyses people cite theguardian.com theguardian.com. But the “why” isn’t one clean answer. It’s more like… a pile of smaller reasons, and they stack.
Physiology side (the boring-but-true stuff):
Women tend to burn a bit more fat and a bit less carbohydrate at marathon effort. That matters because carbs (glycogen) run out. And once they run out, you get that “oh wow, I’m dying” moment. So if you spare glycogen even a little, you might delay the wall, or avoid the full meltdown. That’s one theory for why women hold pace better late.
There’s also the heat/hydration angle people talk about—women might handle heat stress a bit differently. Smaller body mass, maybe different sweating patterns, all that. Not saying women are immune to heat (lol no), but it could reduce the late-race crash in hot races for some runners.
Psychology + behavior side (the part I see every weekend):
Men are more likely to go out hot. Like… really hot. Sometimes it’s ego, sometimes it’s competitiveness, sometimes it’s just “I felt good so I went faster.” And that sentence has ended so many marathons it’s not even funny.
Women often start more conservatively and don’t panic if people pass them early. That alone can keep the whole race from turning into damage control at mile 18. And yeah, some people argue this is social conditioning—women told to be cautious, men told to be bold. Maybe. Or it’s self-selection—who signs up for marathons, who trains seriously, who follows plans. Probably all mixed together.
Also: there might just be more men in races, so you see more chaos behavior because the pool is bigger. More “send it” guys. More bad pacing experiments.
My coaching view (where I’m less polite):
If I hand a strict pacing plan to a male runner, there’s a higher chance he’ll freestyle it because he got excited. If I hand it to a woman, she usually follows it like it’s written in stone. Sometimes too strictly—like she won’t adjust when it’s 30°C and humid and the course is hilly. But the point is: the plan gets executed. And execution is what keeps pacing even.
And yeah, I’ve also seen that patience thing: women don’t mind “losing” the first half if it means they can keep moving the second half. That’s how you end up passing people late instead of joining the walking parade.
Ultra stuff (the weird long-distance bonus):
There’s research and a lot of race history suggesting that as distances increase, women can shine more in pacing and sometimes even overall performance. Marathon is long, ultras are longer, and the longer it goes, the more patience + steady fueling + steady head becomes the whole game. That’s where those strengths can pop.
So if you want the simple version: women pace more evenly because on average they’re a little more patient, a little less “prove it early,” and their physiology might help them not implode as hard when glycogen gets low. But none of this is destiny. It’s tendencies.
And the best part is: pacing is learnable. You can practice it. Anyone can.
Q: What if I’m way slower than average? (E.g., 6+ hour marathon)
A: That’s okay. Like genuinely okay.
Somebody is always going to be at the tail end of the bell curve. That doesn’t make you less legit. A 6+ hour marathon can happen for a million reasons: run/walk plan, tough course, heat, first-timer nerves, GI chaos, life stress, not enough training time, just being new to running speed. Sometimes it’s literally “I just wanted to finish and not get hurt.” That’s valid.
And yeah, if you’re happy finishing at that pace, you don’t need to “fix” it. You’re still a marathoner. You still did 26.2.
If you do want to improve, you can chip away at it. A lot of people start at 6–7 hours and move into the 5–6 range later. Then maybe 5–5:30. It’s not magic. It’s just time + consistency + learning what works.
Also, the marathon crowd usually loves late finishers. At big races, the loudest cheering can be at the end because people know you’ve been out there fighting for hours. One of my most emotional memories is seeing an older woman finish after 6+ hours and the announcer saying it was her first marathon at age 70. Standing ovation stuff. Nobody was like “ugh slow.” Everyone was like “holy hell, look at her go.”
And if your brain keeps asking “how do I rank?”… try switching the question to something that actually helps:
Did you keep moving when you wanted to quit? Did you manage your pain and fear? Did you handle the day you were given? Did you learn something you’ll use next time? Those questions matter more than percentile.
SECTION: Final Coaching Takeaway
Alright. Here’s what I want you to leave with, and I’m saying it straight:
Your marathon time is information. It’s not your identity.
The average woman might finish around 4:45, cool. That’s a data point. But averages don’t know your life. They don’t know your sleep, your stress, your injuries, your kids, your hormones, your work schedule, your training history, your fear on the start line, the heat on the course, the fact you had to stop to pee twice, whatever.
I’ve been running and coaching long enough to see a pattern: the people who get the most out of this sport aren’t always the ones with the fastest times. It’s the ones who show up honestly. They listen to their body. They train consistently. They mess up, learn, come back. They don’t need perfection.
And I’m not gonna wrap this in a clean little bow like “the key takeaway is…” because that’s not real life. Real life is messy. Sometimes you train hard and still have a rough race. Sometimes you barely train and have a surprisingly good day. Sometimes your stomach betrays you at mile 14 and you spend the rest of the race bargaining with God. That’s marathon running.
If you’re a woman wondering where you stand—just know you stand among a massive crowd of women finishing all across the spectrum. There is no wrong place to be. Sub-4, sub-5, over-5, over-6. Still counts. Still hard. Still earned.
I keep thinking about that stranger’s line from my first marathon: “The clock is background noise.”
That’s not some cute quote. It’s true. Because at the finish, volunteers don’t check if you “deserved” the medal based on time. They give it to you because you did the thing.
And years from now, you probably won’t remember the exact seconds. You’ll remember the parts where you wanted to stop and didn’t. You’ll remember the mental battle. You’ll remember what it felt like to keep moving forward when everything inside you was screaming to quit.
So run your marathon. Own your pace. Learn what you can. And don’t let comparison steal the one thing this sport is actually good at giving you: that gritty, stubborn proof that you can do hard things
