Half Marathon Times for Women

What is a good finishing time for my first half marathon? I am a 29-year-old woman, relatively new to running. – Lori

Hi Lori,

What a brilliant question — and well done for already thinking about your first half marathon. That alone puts you ahead of most people.

Here's what we'll cover:

1. What the average half marathon finishing time for women actually looks like
2. How to set a realistic goal for your first race
3. Pacing strategy — why not going out too fast is the single biggest factor on race day

1. What Are Average Half Marathon Times for Women?

The average half marathon finishing time for women across all age groups sits at roughly 2 hours 24 minutes. That's the middle of the pack — the broad, wonderfully ordinary middle where most recreational runners land.

To put that in context: the top 20% of women finish in under 2 hours. The top 10% come in under 1:57. Elite women run under 1:10 — genuinely extraordinary, and not a useful benchmark for the rest of us.

At the other end, there are walkers and walk-runners finishing in 3 hours or more. Every single one of them belongs on that course.

The range is enormous — and that's exactly the point. I remember my wife doing her first 5K and worrying she'd be too slow. It was only when I pulled out the previous year's results — times ranging from 14 minutes to 1:20 for a 5K — that she realised her 30-minute finish was perfectly fine. The half marathon is no different. You will not be last, and even if you were, finishing a half marathon is an achievement worth celebrating.

For a 29-year-old woman at your stage of running, finishing anywhere between 2:10 and 2:40 on a first attempt is completely normal. Some will go faster; many will go slower. The time matters far less than you think it does right now.

2. How to Set a Realistic Goal Time

Finishing is good. Negative-splitting — running the second half faster than the first — is better. But setting a realistic goal and then actually executing on it? That's the best outcome of all for a first half marathon.

The trick is to base your goal on something real, not guesswork. The most reliable method is to use the Race Conversion Calculator. Plug in a recent race time — a 5K, a 10K, anything — and it will give you a solid half marathon prediction.

Haven't raced yet? That's fine. Run a time trial during one of your training sessions. The longer the distance, the more accurate the estimate — I'd suggest at least 8–10 kilometres if you can manage it. Even a hard 5K effort will give you something to work with.

Once you have a target time, break it into kilometres or miles and write down your target pace per kilometre. Then stick to it. It will feel easy for the first 10K — and that's exactly what you want. Easy early on is not a warning sign; it's the plan working.

One more thing: don't obsess over the number. Your first half marathon is about learning the distance. You'll race it again with much better data — and a much faster time — if you run this one with patience.

3. Pacing Strategy — Why the First 10K Is a Trap

Here's what I see again and again at half marathons: runners go out too fast in the first 5K, feel fantastic, and convince themselves they can hold the pace. By kilometre 15, they're in trouble. By kilometre 19, they're walking — and wondering what went wrong.

What went wrong is that the half marathon is long enough to punish overconfidence — but short enough that people forget to respect it.

The first 10K of a half marathon should feel almost suspiciously easy. If it doesn't, you're going too fast. Overcooking that opening stretch isn't about running out of fuel this early — it's that you're pushing beyond what your current fitness can sustain, and that debt comes due in the second half.

Run the first half at a sensible, controlled pace — ideally 5–10 seconds per kilometre slower than your target average — and you'll find the second half far more manageable. That's how negative splits happen. Not by pushing harder in the second half, but by being disciplined in the first.

A useful cue: if you can't hold a short conversation during the first 5K, ease off. You should be running at a pace that feels almost too comfortable. That feeling won't last — but it's your biggest asset early on.

4. What "Good" Really Means for a First Half Marathon

There is no bad finishing time for a first half marathon. A 2:00 is not better than a 2:30 in any meaningful sense — both require months of commitment, early mornings, tired legs, and real courage on race day.

That said, I think a better question than "what's a good time?" is: did you run the race you trained for? If you set a sensible goal, paced yourself well, and crossed the finish line feeling strong — that's a genuinely good race, whatever the clock says.

As you gain experience and your running builds, the times will follow. The runners who improve most reliably are not the ones who race hardest on day one — they're the ones who run smart, listen to their body, and come back for more. Your first half marathon is the start of something, not the final word on what you can do.

Best of luck, Lori — I hope you enjoy every step of it. The half marathon is a wonderful distance, and I suspect it won't be your last :)

Kind regards,
