If you want the one-line answer: a good half marathon time for a recreational runner is around 1:55–2:00 for men and 2:10–2:15 for women, based on aggregated finisher data from RunRepeat, Strava, and race timing companies. That's roughly the median for the 21.0975 km distance — half of all finishers come in faster, half slower. The honest version, of course, is "it depends": age, training history, terrain, and what you're actually chasing all change what counts as good for you.
The half marathon is the most popular road race distance in the world, with millions of finishers a year, so the dataset is enormous and the benchmarks are unusually reliable. Below are the real numbers by age and gender, the experience tiers most coaches use, and a quick formula to predict your half from a recent 10K. By the end you'll know exactly where you stand and what to chase next.
Average half marathon times by age and gender
The most widely cited dataset on amateur half marathon times is RunRepeat's analysis of millions of race results, with cross-checks against Strava's annual Year in Sport data and Running USA's State of the Sport reports. Numbers below are rounded to the nearest 30 seconds — the underlying samples vary by year and country, and these are best used as ballparks rather than precise targets.
| Age group | Men (average) | Women (average) |
|---|---|---|
| Under 20 | 1:49:00 | 2:13:00 |
| 20–29 | 1:55:00 | 2:10:00 |
| 30–39 | 1:58:30 | 2:11:30 |
| 40–49 | 2:02:00 | 2:15:00 |
| 50–59 | 2:07:30 | 2:21:00 |
| 60–69 | 2:16:00 | 2:32:00 |
| 70+ | 2:34:00 | 2:54:00 |
A few things worth noticing in that data. First, the slowdown from your 20s to your 50s is genuinely shallow — about 10–15 seconds per kilometre across three decades. Plenty of runners set lifetime half marathon bests in their early 40s, especially if they only started training seriously in their 30s. Second, the curve bends harder after 60, but it never falls off a cliff: well-trained 65-year-olds routinely run sub-1:45.
For context, Strava's most recent Year in Sport report pegged the global average running pace across all logged activities at around 6:20/km. At that pace, a half marathon comes in around 2:13 — which lines up cleanly with the median female finisher and within a couple of minutes of the median male. If you can hold sub-2:00 for the half, you're meaningfully faster than the typical runner showing up on Strava.
First-time half marathon finishers
If this is your first half marathon, the relevant data is different — most aggregators put first-time finishers at 2:05–2:15 for men and 2:20–2:30 for women, with a long tail of finishers in the 2:30–3:00 range. If your debut half lands anywhere in those windows, you're exactly where you should be. The classic beginner mistake isn't running too slowly — it's setting a goal pace based on what intermediate runners post online and then blowing up at 16K.

Benchmarks by experience level
Race times alone don't tell you much without context. The labels below align with what Running Level's amateur-runner database and most club coaches use day-to-day.
- Finisher (just completing the distance): 2:30 and slower. The goal is the medal, not the clock. Roughly a third of first-time half marathoners land here.
- Recreational: sub-2:00 for men, sub-2:15 for women. You've trained 10–14 weeks, you can run the whole thing without walking, and you have a working pace plan. This is where most consistent club runners sit after a year or two.
- Intermediate: sub-1:45 for men, sub-2:00 for women. You're racing now, not just running. Typically 40–55 km per week with one quality session.
- Advanced: sub-1:30 for men, sub-1:40 for women. Local age-group podium territory. Usually 60–80 km per week, with structured tempo and threshold work.
- Competitive: sub-1:20 for men, sub-1:30 for women. Front-of-the-pack at most regional half marathons. 80–110 km per week, often with a coach.
- Elite / world-class: sub-1:02 for men, sub-1:08 for women. Olympic-medal territory. Jacob Kiplimo holds the men's world record at 57:20 from the EDP Lisbon Half Marathon in March 2024 (the 56:42 he ran in Barcelona in February 2025 was disqualified by World Athletics). Letesenbet Gidey holds the women's world record at 1:02:52, set in Valencia in October 2021 — she remains the only woman ever under 63 minutes.
The gap between recreational and intermediate is where most runners spend the longest stretch of their running life, and it's also the gap where small training tweaks pay off the most.
What actually affects your half marathon time
Two runners with similar fitness can finish minutes apart on the same course. The biggest factors:
- Weekly mileage. The single best predictor of half marathon performance, by some distance. Going from 30 to 50 km per week, with the extra volume run easy, typically drops a half by 5–8 minutes inside a season.
- Long run length. Runners who top out their longest run at 14 km tend to fade hard from 16K onwards. Runners who regularly hit 18–22 km in training have the aerobic depth to hold pace into the final 5K. The long run is the workout the half marathon rewards most.
- Course profile. A flat, point-to-point road half is roughly 2–4 minutes faster than a rolling-hills course at the same effort, and a trail half can be 10–20 minutes slower depending on technicality. If you ran 1:55 in Berlin and 2:03 on a hilly local course, you didn't get less fit — you ran a harder race.
- Weather. Half marathon performance starts to decline above about 13 °C (55 °F). At 25 °C (77 °F), expect to lose 2–4 minutes versus a cool day, even at identical effort.
- Pacing. Going out too fast is the most common cause of a "bad" half. The fastest halves for most amateurs are even-pace or slight negative splits.
- Sleep and stress. A bad week of sleep into race day is worth 1–2 minutes over 21K. It's not in your head.
Predicting your half from a recent 10K
If you've raced a 10K recently and want a realistic half marathon target, the standard tool is the Riegel formula:
T2 = T1 × (D2 / D1)^1.06
Where T1 is your recent time, D1 is the distance you raced, and D2 is the distance you want to predict. The 1.06 exponent reflects how pace fades with distance for trained runners.
Worked example. Say you ran a 10K in 50:00. To predict your half marathon (21.0975 km, not 21):
- T2 = 50 × (21.0975 / 10)^1.06
- T2 = 50 × 2.10975^1.06
- T2 = 50 × 2.2064
- T2 ≈ 110.3 minutes ≈ 1:50:19
So a 50-minute 10K runner should be in shape for about a 1:50 half on a similar course in similar weather. The formula is most accurate when you've trained for both distances. If you've only ever raced 10Ks and your longest run has been 12 km, expect the half to come in 2–4 minutes slower than the prediction — the half marathon punishes a thin endurance base.
For a deeper walk-through of Riegel, including how it scales to the marathon and where it breaks down, see the 10K benchmarks guide.
How to actually run a faster half
If your current half is in the average range and you want to break into the next tier, four sessions cover almost everything that matters. You don't need all of them every week — pick two or three and rotate across a 10–14 week training block.
- A real long run, weekly. Build to 16–20 km at conversational easy pace, ideally 60–75 seconds per kilometre slower than half marathon race pace. The point is aerobic depth and time on feet, not speed. Skip the long run and the last 5K of your race will tell you about it.
- Tempo run, once a week. 30–40 minutes at "comfortably hard" pace, roughly 5–10 seconds per kilometre slower than current half marathon race pace. This is the single biggest physiological lever for half marathon performance — it raises the speed at which you accumulate lactate, which is exactly what you're trying to delay over 21 km.
- Race-pace specificity. Closer to race day, run sessions at goal half marathon pace. A classic: 3 × 5 km at goal pace with 3 minutes easy jog between reps, or 2 × 6 km at goal pace with 4 minutes recovery. If you can complete these cleanly 2–3 weeks out, your goal pace is realistic. If you can't, adjust the goal — don't grind through a workout you're failing.
- Consistency over heroics. Running four times a week for 12 weeks beats running six times a week for three weeks and then getting injured. Most half marathon breakthroughs come from a full, uninterrupted training block — not from a hero workout the week before the race.
One more thing worth saying out loud: improvement is not linear. Most runners drop 5–10 minutes from their half in their first year of structured training, then 2–4 minutes the next year, then fight for every 60 seconds after that. That's normal. It's also why the runners who keep going past year three end up surprisingly fast.
Plan your race and run it
Once you know the time you're aiming for, the next step is knowing exactly what splits you need to hit. Drop your goal half marathon time into the calculator at runpace.co and you'll get the per-kilometre and per-mile splits to hold on race day, plus pace bands for every checkpoint along the 21.0975 km course. The runners who finish well are almost always the ones who decided how they'd run before the gun went off.
