1:30 half marathon pace: how to run a sub-1:30 half
1:30 half marathon pace is 4:16 per km or 6:52 per mile, and 6:52 miles finish in 1:30:01. Splits, percentiles, the sessions, fueling and race pacing.
1:30 half marathon pace is 4:16 per kilometer, or 6:52 per mile. That's the 1 30 half marathon pace everyone quotes, and it has a catch: hold exactly 6:52 miles or 4:16 kilometers for 21.0975 km and the clock says 1:30:01. Both numbers round down from the true pace, so running them dead even misses the goal by a second.
So the real answer to "what pace is a 1:30 half marathon" is: a touch quicker than the number on every pace chart. This post covers the exact paces, splits, where 1:30 sits in real race data, what fitness it usually takes, the sessions that build it, fueling and race-day pacing. Build the plan yourself, or use an app that adjusts your runs to how you recovered.
What pace is a 1:30 half marathon?
The math: 1:30:00 is 5,400 seconds. Divided by 21.0975 km, that's 255.95 seconds per km, which rounds to 4:16 but is really just under it. Multiply by 1.609344 for miles: 411.9 seconds, which rounds to 6:52 but again sits just under.
Those fractions are why rounded paces miss. Over 21 km, a fraction of a second per kilometer adds up to the one second that turns 1:29:59 into 1:30:01. If you'd rather test other targets, a pace calculator does the same sum. The full conversion tables live in the running pace guide, and every number here matches it.
1:30 half marathon pace per mile and per km, with a buffer
| Target finish | Per km | Per mile |
|---|---|---|
| 1:30:00 | 4:16 (4:15.95) | 6:52 (6:51.9) |
| 1:29:35 | 4:15 | 6:50 |
| 1:29:19 | 4:14 | 6:49 |
| 1:29:00 | 4:13 | 6:47 |
Plan around 6:50 per mile or 4:14 to 4:15 per km. That's 25 to 40 seconds of buffer, which you'll need: road courses are measured on the shortest line, and nobody runs the shortest line.
Sub 1:30 half marathon pace is also exactly 3:00 marathon pace. If you've ever wondered how fast our guide to sub-3 marathon pace and training really is, it's this, held for twice as long.
Sub-1:30 half marathon splits
Even pace for exactly 1:30:00:
| Distance | Split | Distance | Split |
|---|---|---|---|
| 5 km | 21:20 | 3 miles | 20:36 |
| 10 km | 42:40 | 5 miles | 34:20 |
| 15 km | 1:03:59 | 10 miles | 1:08:39 |
| 20 km | 1:25:19 | 13 miles | 1:29:15 |
| 21.0975 km | 1:30:00 |
How a 1:30 half compares with the field
RunRepeat's percentile calculator, built from millions of race results, gives median half marathon times of 2:14:59 overall, 1:59:48 for men and 2:24:03 for women. At the fast end, the page says: "To be among the fastest 10% of men, you should have a finish time faster than 01:40:35 hours." For women: "And to be among the fastest 1% you should be faster than 1:35:55 hours." Overall: "To be among the best 1% you should aim to be faster than 1:23:59 hours."
So a 1:30 is more than 10 minutes inside the fastest 10% of men in RunRepeat's data, and almost six minutes inside the fastest 1% of women. That's not a "good for a lifter" time. It's a fast time, full stop.
For perspective, what is the pace for a 2 hour half marathon? 5:41 per km. A 1:30 is 85 seconds per kilometer quicker, for the same 21 km.
What fitness a 1:30 half usually takes
Coaching practice, not a promise. People who break 1:30 typically have:
- 10K and 5K speed in hand. Most equivalence calculators pair a 1:30 half with a 10K somewhere around 40 to 42 minutes and a 5K around 19:30 to 20:00. If you can't yet run a sub-20 5K, you're probably not yet a sub-1:30 runner.
- Real weekly volume. Five or six runs a week, often somewhere around 35 to 50 miles in the build, with a long run of 90 to 110 minutes. Some people get there on less, but it's rarely a four-runs-a-week target.
- A threshold a little faster than goal pace. For most runners at this level, half marathon pace sits a few seconds per kilometer slower than threshold. If 4:16 per km feels like a tempo run, good. If it feels like a race, give it another block.
The benchmark session: 3 × 5 km at 4:14 to 4:16, with 3 minutes easy jogging, about three weeks out. That's 15 km of goal pace. Controlled throughout? Sub-1:30 is on.
Key workouts for a 1:30 half marathon
Two quality sessions a week plus a long run that occasionally has a job. The half rewards long, controlled efforts, so most of the hard work sits between goal pace and 10K effort.
1. Threshold intervals
4 × 10 minutes at threshold effort (RPE 7–8, zone 4 in the five-zone model we use), roughly 4:05 to 4:10 per km for most 1:30 runners, with 2 minutes easy. Progress to 3 × 15 minutes. This raises the ceiling so 4:15 sits comfortably under it.
2. 10K-effort kilometers
8 × 1 km at about 4:03 to 4:08, with 75 seconds of jogging. Faster than goal pace, short enough to keep form. Use these early in the build and every two or three weeks after.
3. Float long run
14 to 18 km alternating 1 km at goal pace (4:14 to 4:16) and 1 km at a steady 4:40 to 4:50, with no stopping. The "float" kilometers aren't recovery; they're slower running you're not allowed to walk. It teaches you to hold pace when you're already working, which is the last 6 km of the race.
4. Race-pace 5Ks (late in the block)
The benchmark session above: 3 × 5 km at 4:14 to 4:16. Do it once or twice in the final month, not weekly.
Every other run is easy, and the long run is mostly easy too. Easy enough to talk. Run your easy days at 4:45 and you show up flat for the sessions that count.
Strength training for a 1:30 half
Keep lifting. A review by Rønnestad and Mujika (2014) concluded that combining endurance training with either heavy or explosive strength training improves running economy in endurance-trained runners, and can improve running performance. Better economy means 4:15 per km costs less oxygen.
At this level the running volume is high, so the lifting has to be lean:
- Two sessions a week, short. A squat or hinge variation, a single-leg movement, calves and some upper body. Three or four sets of four to six reps, a rep or two in reserve.
- Heavy legs on a hard day, after the run, or on an easy day. Never the day before intervals or the long run.
- Last real lower-body session about a week to ten days out.
A sub-1:30 half marathon week
Five runs, two lifts, mid-build:
| Day | Run | Lift |
|---|---|---|
| Mon | Easy 40 min + strides | Upper body |
| Tue | Threshold intervals or 10K-effort kms | Lower (heavy, low volume), after the run |
| Wed | Easy 45–50 min | — |
| Thu | Second quality: threshold or race-pace work | — |
| Fri | Rest | Optional light full body or mobility |
| Sat | Easy 30–40 min | — |
| Sun | Long run, 90–110 min (some weeks a float run) | — |
If you need six runs, add an easy 30 minutes on Friday and keep Saturday short. If Thursday is consistently flat after Tuesday's lift, cut a set from the lift before cutting anything from the running.
Fueling for 1:30
A 1:30 half is right in the range where carbohydrate during the race is worth practicing. The ACSM, Academy of Nutrition and Dietetics and Dietitians of Canada joint position stand gives 30 to 60 g of carbohydrate per hour for sustained exercise of 1 to 2.5 hours, and 1 to 4 g/kg in the 1 to 4 hours before. For most people that means a normal carb-based breakfast and a gel or two on the course. Rehearse it on long runs. Nothing new on race day.
1:30 half marathon race-day pacing
Most half marathoners slow down. In an analysis of 208,760 finishers of the Vienna City Marathon and half marathon from 2006 to 2018, Ristanović et al. (2023) observed positive pacing, a decrease in speed, in all performance groups of both sexes and both races. Better runners showed more even pacing than slower ones. Even pacing is what you're aiming for.
- First 3 km: 4:16 to 4:18. Slightly slow. The crowd and fresh legs will suggest 4:05. Ignore them.
- 3 km to 15 km: lock into 4:14 to 4:15. Use course markers as well as the watch, because GPS drifts.
- 15 km: check the clock. 1:03:59 is exactly 1:30 pace. If you've run 4:14s since 3 km, you'll be roughly 10 to 20 seconds ahead. Hold it.
- 10 miles: 1:08:39 is exactly on pace. From here, it's a 5K race on tired legs. You know how to do that.
- Last 3 km: everything left.
Where 1:30 leads
The 1:30 half sits in a neat spot in the pace tables. At the other end of them, what pace is a 5 hour marathon? 7:07 per km, a reminder that distance changes the problem more than pace does. An 8 min mile marathon time is about 3:29:45. And going the other way from your 6:52s, more on 11 minute mile half marathon time: about 2:24:12 for the same 13.1 miles.
Faster still, a sub-18 5K at 3:36 per km and a sub-40 10K at 4:00 per km are the speed targets that usually come before a 1:25 half. Same engine, more horsepower.

FAQ
What is 1:30 half marathon pace per mile?
6:52 per mile rounded, but the true figure is 6:51.9. Running exactly 6:52 miles gives about 1:30:01, so aim for 6:50 per mile, which brings you in around 1:29:35.
What is 130 half marathon pace per km?
4:16 per km rounded, or 4:15.95 exactly. Run 4:14 to 4:15 per km to leave a buffer for course distance.
Is a sub-1:30 half marathon good?
Yes. RunRepeat says men need to be faster than 01:40:35 to be among the fastest 10%, and women faster than 1:35:55 to be among the fastest 1% (RunRepeat).
What 10K time do I need for a 1:30 half marathon?
Most equivalence calculators pair a 1:30 half with a 10K of around 40 to 42 minutes. Take that as a rough guide, because the half also needs the endurance to hold pace for 21 km.
Should I take gels in a 1:30 half marathon?
Many runners do. The joint ACSM position stand gives 30 to 60 g of carbohydrate per hour for exercise lasting 1 to 2.5 hours (ACSM/AND/DC, 2016), so practice it in training first.
