The short answer: the average marathon time is roughly 4:25–4:30 overall, about 4:10–4:15 for men and about 4:40 for women, based on RunRepeat's analysis of US race results. That works out to a pace of around 6:17–6:24 per kilometre (10:06–10:18 per mile). Roughly a third of finishers break 4 hours, about 10–12% break 3:30, and only around 4% break 3:00.
Big European races tell the same story. The 2026 Paris Marathon published a mean finish of 4:13:24 (men 4:04:41, women 4:32:09), and the average finish at London 2025 was about 4:40 — London's ballot favours charity and first-time runners, which pulls the average up.
So what is a good marathon time? Anything under the median for your age and gender is above average by definition. Sub-4:00 puts you in the top third. Sub-3:30 puts you in roughly the top tenth. The rest of this guide is the detail: average marathon time by age, the experience tiers coaches use, how long it takes to walk one, and the pace maths for every common target.
Average marathon time by age and gender
Marathon finish times follow a predictable curve. They are slowest for under-20s (few of whom have the mileage base) and over-55s, and fastest in the 30–34 and 35–39 age groups — the marathon rewards years of accumulated training more than raw youth. The gender gap among recreational runners is roughly 25–30 minutes at every age.
The table below is built from that pattern around the RunRepeat medians (men ~4:10–4:15, women ~4:40). Values are approximate and rounded to the nearest 5 minutes; treat them as ballparks, not precise percentiles.
| Age group | Men (approximate) | Women (approximate) |
|---|---|---|
| Under 20 | 4:30 | 5:00 |
| 20–24 | 4:15 | 4:45 |
| 25–29 | 4:10 | 4:40 |
| 30–34 | 4:05 | 4:35 |
| 35–39 | 4:05 | 4:35 |
| 40–44 | 4:10 | 4:40 |
| 45–49 | 4:15 | 4:45 |
| 50–54 | 4:20 | 4:50 |
| 55–59 | 4:30 | 5:00 |
| 60–64 | 4:40 | 5:10 |
| 65+ | 4:55 | 5:25 |
Two things worth noticing. First, the curve is remarkably flat from 25 to 50 — a 48-year-old running 4:15 is doing exactly as well, relative to peers, as a 26-year-old running 4:10. Second, the average time for women is not "slower women" so much as a different mix of runners: more first-timers, more charity places, and a longer tail of 5:00+ finishers. Among runners with the same training history, the gap narrows considerably.
Average marathon time for men
Roughly 4:10–4:15 in US data, 4:04:41 at Paris 2026. The fastest cohort is men aged 30–39 at around 4:05. A man finishing under 4:00 is faster than well over half of male finishers; under 3:30 is top 10% territory.
Average marathon time for women
Roughly 4:40 in US data, 4:32:09 at Paris 2026. Women aged 30–39 average around 4:35. A woman finishing under 4:30 is above average; under 4:00 is comfortably in the top quarter of female finishers.
What is a good marathon time?
Averages tell you where the middle is. Experience tiers tell you what "good" means for a runner like you. The thresholds below mirror the tiers in our 10K benchmarks guide, scaled to the marathon.
| Tier | Men | Women | What it usually takes |
|---|---|---|---|
| First-timer | 4:30–5:30 | 4:45–5:45 | 16–20 weeks of training, peaking at 50–65 km (30–40 miles) a week. Finishing is the goal. |
| Recreational | 4:00–4:30 | 4:30–5:00 | A year or more of consistent running, 50–70 km a week in the build. This is where the median sits. |
| Intermediate | Sub-4:00 | Sub-4:30 | Structured long runs of 30–35 km, a weekly tempo, 60–80 km a week. Roughly the top third. |
| Advanced | Sub-3:30 | Sub-3:50 | 80–100 km a week with marathon-pace long runs. Roughly the top 10–12% (sub-3:30) of all finishers. |
| Competitive | Sub-3:00 | Sub-3:25 | 100+ km a week, several years of racing. Boston-qualifying territory; only around 4% of finishers break 3:00. |
| Elite | Sub-2:20 | Sub-2:40 | Full-time athletes. The world records are 1:59:30 (men) and 2:09:56 (women). |
Where does a first marathon time land? Most first-timers finish between about 4:30 and 5:30. If you ran your first marathon under 5:00 without walking the back half, that is a genuinely good beginner marathon time — you are already around the overall median on your first attempt.
Boston qualifying times as a benchmark
The Boston Marathon qualifying standard is the most widely used "fast amateur" yardstick. The current standards, introduced for the 2026 race and unchanged for 2027, are 2:55:00 for men aged 18–34 and 3:25:00 for women aged 18–34 — five minutes tighter than the old 3:00 and 3:30 lines. The standards loosen with age in 5-year groups, but the standard alone has not been enough in recent years: more runners qualify than there are places, so the actual cut-off for the 2027 race was 5 minutes 17 seconds faster than the standard, meaning a man aged 18–34 needed roughly 2:49:43 to be accepted.
| Standard | Time | Pace per km | Pace per mile |
|---|---|---|---|
| Boston Q, men 18–34 (2027) | 2:55:00 | 4:09 | 6:40 |
| Boston Q, women 18–34 (2027) | 3:25:00 | 4:52 | 7:49 |
How long does it take to run a marathon?
For a runner, the honest range is 3 to 6 hours, with most people between 3:45 and 5:15. For a run/walker or walker, it is longer.
| Approach | Typical finish | Pace per km | Pace per mile |
|---|---|---|---|
| Trained runner (median) | 4:25–4:30 | 6:17–6:24 | 10:06–10:18 |
| Run/walk (e.g. 4 min run, 1 min walk) | 5:00–6:00 | 7:07–8:32 | 11:27–13:44 |
| Brisk walk, no running | 6:30–7:30 | 9:15–10:40 | 14:52–17:10 |
| Relaxed walk | 7:30–8:00+ | 10:40–11:23+ | 17:10–18:18+ |
Walking a marathon in 7 hours means averaging 9:57 per km (16:01 per mile), or about 6 km/h — a brisk, purposeful walk sustained for seven hours without long stops. Walking an 8-hour marathon is 11:23 per km, which is closer to an ordinary walking pace.
The practical constraint is the course cut-off. Most big-city marathons close the course 6 to 7 hours after the last start wave; some are tighter (5:30–6:00), and a few walker-friendly events allow 8 hours or more. If you plan to walk, check the cut-off before you enter, and note whether it runs from the gun or from your own start time.
Marathon finish time to pace
Every goal time is really a pace target. The table below converts the common ones using the exact marathon distance of 42.195 km (26.2188 miles). The marathon pace chart has the full range in finer steps.
| Finish time | Pace per km | Pace per mile | km/h | mph |
|---|---|---|---|---|
| 2:30 | 3:33 | 5:43 | 16.9 | 10.5 |
| 3:00 | 4:15 | 6:52 | 14.1 | 8.7 |
| 3:15 | 4:37 | 7:26 | 13.0 | 8.1 |
| 3:30 | 4:59 | 8:01 | 12.1 | 7.5 |
| 3:45 | 5:20 | 8:35 | 11.3 | 7.0 |
| 4:00 | 5:41 | 9:09 | 10.5 | 6.6 |
| 4:15 | 6:03 | 9:44 | 9.9 | 6.2 |
| 4:30 | 6:24 | 10:18 | 9.4 | 5.8 |
| 4:45 | 6:45 | 10:52 | 8.9 | 5.5 |
| 5:00 | 7:07 | 11:27 | 8.4 | 5.2 |
| 5:30 | 7:49 | 12:35 | 7.7 | 4.8 |
| 6:00 | 8:32 | 13:44 | 7.0 | 4.4 |
A useful rule of thumb from that table: every 10 seconds per km is worth about 7 minutes over the marathon, and every 30 seconds per km is worth 21 minutes. Moving from the 4:30 median to a sub-4:00 means holding 43 seconds per km faster for the entire race — which is why the sub-4 barrier is a bigger deal than it looks.
For context, the men's world record of 1:59:30 is 2:50 per km and the women's 2:09:56 is 3:05 per km — the median recreational runner is running more than twice as slow per kilometre. See marathon world records for the full history.
How to predict your marathon time
If you have raced a half marathon recently, you can estimate your marathon with the Riegel formula:
T2 = T1 × (D2 / D1)^1.06
T1 is your recent time, D1 the distance you raced, D2 the distance you want to predict. The 1.06 exponent captures how pace fades as the distance grows. Because a marathon is exactly twice a half marathon, the ratio simplifies to 2^1.06 = 2.0849.
Worked example. Say you ran a half marathon in 1:55:00 (115 minutes):
- T2 = 115 × 2^1.06
- T2 = 115 × 2.0849
- T2 = 239.8 minutes
- T2 ≈ 3:59:46
So a 1:55 half marathon runner is in shape for roughly a 4-hour marathon — about 10 minutes slower than simply doubling the half time, which is where the "double it and add 10" folk rule comes from. The same maths gives a 1:45 half → 3:39, a 2:00 half → 4:10, and a 2:10 half → 4:31.
Two caveats. Riegel assumes you are trained for the distance you are predicting: if your longest run is 25 km, add 10–20 minutes. And it assumes similar conditions — a warm day or a hilly course can add as much again. The half marathon benchmarks guide covers where your half time sits in the first place.
What makes a marathon time slower or faster
Two runners with identical fitness can finish 20 minutes apart. The usual suspects:
- Course. A flat, sea-level, big-city course with crowds every mile is worth several minutes over a rolling or exposed one. Net-downhill courses can be faster still, but they punish the quads late on if you have not trained for them.
- Weather. Marathon performance deteriorates above roughly 10–12 °C (50–54 °F) and falls off sharply above 20 °C (68 °F). A warm day can cost the median runner 10–20 minutes; the fastest runners lose proportionally less because they are out in the heat for less time.
- Pacing. Going out too fast is the single most common reason a marathon ends up slower than the training suggested. The fastest marathons for most people are even or slightly negative splits — see marathon pacing: even, negative and positive splits.
- Fuelling. Running out of carbohydrate around 30–35 km ("the wall") can add 15–30 minutes on its own. Taking on 60–90 g of carbohydrate per hour from early in the race, practised in training, removes most of that risk.
- Taper and race week. Arriving fresh is worth minutes; arriving tired from a last-minute long run costs them. The 7-day race week taper covers what to do and what to skip.
FAQ
What is the average marathon time?
Roughly 4:25–4:30 across large US datasets, per RunRepeat's analysis of US race results — about 4:10–4:15 for men and 4:40 for women. Individual races vary: the Paris Marathon 2026 mean was 4:13:24, while London 2025 averaged about 4:40 because of its large first-timer and charity field.
What is a good marathon time for a beginner?
A first marathon time between 4:30 and 5:30 is typical, and anything under 5:00 is a good beginner marathon time. Sub-4:30 on a first attempt would put you around the overall median — better than half of all finishers, most of whom are not first-timers.
What is a good marathon time for a woman?
The average marathon time for women is roughly 4:40. Sub-4:30 is above average, sub-4:00 is comfortably in the top quarter of female finishers, and sub-3:50 is advanced. The 2027 Boston qualifying standard for women aged 18–34 is 3:25:00.
What is a good marathon time for a man?
The average marathon time for men is roughly 4:10–4:15. Sub-4:00 is above average, sub-3:30 is roughly top 10%, and sub-3:00 is achieved by only around 4% of all finishers. The 2027 Boston qualifying standard for men aged 18–34 is 2:55:00.
Is a 4 hour marathon good?
Yes. Only about a third of marathon finishers break 4 hours, so sub-4 puts you in the top third overall and in the faster half of men and well into the top quarter of women. It requires holding 5:41 per km (9:09 per mile) for 42.195 km, which usually means 60–80 km a week in the training build.
Is a sub 3 marathon good?
Very. Around 4% of marathon finishers break 3 hours. It means averaging 4:15 per km (6:52 per mile) for the full distance — the strict line is 4:15.95/km, so a flat 4:16/km finishes two seconds over — and for most runners it takes 100+ km a week over several years. It is just outside the 2027 Boston standard for men aged 18–34 (2:55:00) and comfortably inside the women's (3:25:00).
How long does it take to walk a marathon?
Roughly 6:30 to 8 hours at a brisk walk (9:15–11:23 per km), and longer at a relaxed pace. Most big-city courses close after 6–7 hours, so check the cut-off — and whether it is measured from the gun or from your start time — before entering.
