What's a Good Half Marathon Time by Age?

A good half marathon time depends on your age and your gender, and the half rewards a blend of speed and patience. For a man in his 20s, a good half is near 1 hour 30 minutes. For a woman in her 20s, it is near 1 hour 46 minutes. The typical finisher is slower, close to 1 hour 43 minutes for men and 2 hours for women. Good means you finish ahead of most of the field. It does not mean you race for prize money.

What is a good half marathon time by age?

A good half marathon time beats about 80 percent of runners your age and gender. For a man in his 20s, that is near 1 hour 30 minutes. For a man in his 30s, it is near 1 hour 31 minutes. For a woman in her 20s, a good half is near 1 hour 46 minutes, and near 1 hour 47 minutes in her 30s. These come from the advanced standard at Running Level, 2024.

The bar relaxes as the years add up. A good half for a man in his 50s is near 1 hour 46 minutes. For a woman in her 50s, it is near 2 hours 8 minutes. By age 60 and over, a good time is near 1 hour 51 minutes for men and 2 hours 16 minutes for women. None of these sit at the sharp end of the race. They are marks a patient, well-drilled runner can build toward.

a good half marathon for a man in his 20s, faster than 80% of runners (Running Level)

Keep the word good in its place. Good is well clear of the pack, yet a long way from the lead. Running Level's own pool shows the gap. The fastest half in its data is 58 minutes 1 second for men and 1 hour 4 minutes 31 seconds for women (Running Level, 2024). A good time is a personal milestone, not a trophy.

What is the average half marathon time?

The average half marathon time is near 1 hour 43 minutes for men and 2 hours for women. This is Running Level's intermediate standard, the runner who is quicker than half the field (Running Level, 2024). A separate read of about one million 2024 finishers landed higher. It put the median for men in their 20s near 1 hour 59 minutes, and the median for women in their 20s near 2 hours 16 minutes (Outside, 2025).

Why two numbers? Each pool counts a different crowd. One leans on trained runners. The other counts every single finisher, walk breaks and all. Both pictures are fair. They just answer slightly different questions.

The average also drifts slower with age. In that same 2024 data, the median man slows from near 1 hour 59 minutes in his 20s to near 2 hours 19 minutes in his 60s (Outside, 2025). The good column in the table above is the better aim for anyone who wants to improve. The space between average and good is the space between finishing and racing.

Why is the half marathon the most popular goal race?

The half marathon is the race most runners build toward. It is long enough to feel like an achievement, yet short enough to train for around a full life. Its fields have swelled. One review noted that half marathon finishers now outnumber marathon finishers, driven by a wave of newer runners taking up the distance (Nikolaidis et al., 2023). For many people, the half is the first long race they ever try.

That popularity is why the average reads soft. A start line holds a wide mix. First-timers stand next to club racers chasing a fast clock. Both cover the same 13.1 miles. The result then sorts them. So the average runner is not really a racer at all. They are someone out to finish their first big distance.

This also makes the half a natural next step. Many runners arrive after a solid 10K, where the goal was raw speed for a shorter time. If you want to see where you stand at that distance first, read our guide to a good 10K time by age. The half then asks you to hold a strong pace for far longer.

What balance of speed and endurance does the half demand?

The half marathon asks for two things at once. You need a high cruising pace, and you need the patience to hold it across 13.1 miles. Most runners finish between 1 hour 30 minutes and 2 hours 30 minutes. For that whole stretch, you run just under your lactate threshold. That is the fastest pace you can sustain before fatigue piles up faster than your body clears it.

Studies of recreational runners show the demand clearly. Across a half, runners hold close to 80 percent of their aerobic ceiling for the full race (Nikolaidis et al., 2023). That is a high, grinding effort, but not a flat sprint. It sits in the middle of the racing menu. The 10K lives right at your threshold and hurts hard over a shorter span. The marathon eases the pace and tests sheer durability.

This balance shapes what a good half needs. The same research found half time tracked closely with both aerobic fitness and weekly training distance (Nikolaidis et al., 2023). You cannot bluff your way through with speed alone. You also cannot crawl through on volume alone. The half wants both, in fair measure.

How much does age change a good half time?

Age changes a good half time in small, steady steps. Endurance peaks in the late 20s to mid 30s for most runners. After that, race times slip by roughly 6 to 7 percent each decade until the late 50s (Lepers et al., 2021). The fade stays gentle for years before it steepens.

endurance running decline per decade until the late 50s (Lepers et al., 2021)

This is the table at work. A good man's half near 1 hour 30 minutes in his 20s drifts to near 1 hour 46 minutes by his 50s. The runner did not get lazy. The body shifted. The heart moves a little less blood per beat. Some fast muscle fibers fade. Top aerobic power dips in tiny steps. All of it is plain biology.

There is a bright side buried in the same study. Faster runners lose less ground per decade than slower ones (Lepers et al., 2021). Steady training holds the line. A strong masters runner can stay close to their own ceiling well into their later years. Age sets the bar. Your habits decide how near you get to it.

Do you need to fuel during a half marathon?

For most runners, fueling during a half marathon is optional. That single fact makes the distance friendlier than the marathon. Your body stores enough carbohydrate to cover most of a half without a refill. So the brutal wall that ambushes marathoners is rare here. You can race a half on pace and threshold, not on survival math.

Optional is not the same as pointless, though. Runners out longer than about 1 hour 45 minutes often gain from a gel or two late in the race. The more time you spend running, the more your stored fuel matters. A small top-up can hold your pace steady in the final miles.

The marathon flips this rule completely. There, fuel is mandatory, and a missed plan can cost many minutes. That gap is one reason a good half does not scale up into a good marathon by simple math. To see how the longer race punishes mistakes, read our guide to a good marathon time by age. The half forgives more. It still rewards the runner who plans well.

Why your age and gender are only the start

Here is the catch with every time chart. It can show you the middle of your age group, but it knows nothing about you. Put two runners side by side at the same age, same gender, same recent half. One could be tapped out, right at the edge of their fitness. The other could have ten minutes hiding in the tank. A row in a table cannot tell them apart. Your own data can.

PIRX is a proprietary machine-learning prediction engine. It does not lean on your age and gender. It learns from your real runs. It rates the parts of your fitness that decide a half, such as Threshold Density, Aerobic Base, and Running Economy. The half leans hardest on Threshold Density and Aerobic Base, since the race is a high pace held for a long stretch. Each driver reports the gain it can add, in seconds. No wrist VO2 max guess.

What PIRX returns is a Projected Time, not a crowd average. Beside it sits a Supported Range, the spread of finishes your current fitness supports. The engine recalculates after every synced activity. You only see the Projected Time move when the structural change reaches at least 2 seconds, so the number reflects real change, not daily noise. For the wider view, read our complete guide to predicting your race time.

Round-number goals are a great use of this. When you set a clear target, like a sub-2 half marathon, your lowest driver names the exact gap to train. You stop guessing which workout matters. You train the one that moves your time.

See your real half marathon ceiling

Stop ranking yourself against a chart. A chart describes a crowd of strangers. It says nothing about your ceiling. PIRX does. Link your Garmin, COROS, or Strava in about a minute. You get your Projected Half Marathon Time, your Supported Range, and the drivers keeping you back. Then the number falls as you close the right gaps. Free, and no signup.
