The average marathon time in Singapore, by age and gender
What is a good marathon time in Singapore? Based on 8,931 official 2025 finish times, here is the average by age and gender, and how you compare.

The median marathon time in Singapore was 5 hours 17 minutes, but the number that matters is your own age and gender group, and this is where you sit within it.
TL;DR
- The average (median) marathon time in Singapore was 5 hours 17 minutes, slowed by the heat.
- Breaking 4 hours puts you well inside the top of your age group here.
- Breaking 3 hours is rare across every age, at 0 to 1 per cent.
- To be in the fast 10 per cent as a man in your 30s or 40s you needed roughly sub-3:55.

Based on 8,931 official marathon finish times from Singapore's 2025 race. Every finisher, not a sample.
What counts as a good marathon time in Singapore
Most marathon time charts online are built on cooler-climate races, and they will make you feel slow for the wrong reason. Singapore's marathon runs in December heat, at a 4.30am flag-off in the wee hours, in around 27 degrees and humidity above 80 per cent.
The fair benchmark is not a London or Tokyo chart. It is other runners who ran the same race in the same heat, which is exactly what this is: all 8,931 finishers of the 2025 marathon.
The average marathon time by age and gender
These are Singaporean finishers only, so you are comparing yourself to other locals rather than to the travelling runners and elites who fly in.
| Age | Men | Men median | Women | Women median |
|---|---|---|---|---|
| 20-29 | 1,307 | 5:23:14 | 270 | 5:38:04 |
| 30-39 | 975 | 5:10:10 | 180 | 5:21:01 |
| 40-49 | 612 | 5:09:14 | 142 | 5:28:04 |
| 50-59 | 445 | 5:22:55 | 57 | 5:34:54 |
| 60-69 | 137 | 5:48:37 | 22 | 5:50:48 |
Notice that men in their 40s posted the fastest median of any male group, which we dig into in the main study.
Find your percentile
Find your age and gender, then see where your finish time falls. The 10th percentile is the fast end (only one in ten ran faster), the 90th is the back.
Singaporean men, marathon:
| Age | Fast (10th) | Above avg (25th) | Median | Below avg (75th) | Back (90th) |
|---|---|---|---|---|---|
| 20-29 | 4:04:25 | 4:43:01 | 5:23:14 | 6:06:04 | 6:45:10 |
| 30-39 | 3:50:34 | 4:27:43 | 5:10:10 | 5:55:30 | 6:39:10 |

Singaporean women, marathon:
| Age | Fast (10th) | Above avg (25th) | Median | Below avg (75th) | Back (90th) |
|---|---|---|---|---|---|
| 20-29 | 4:29:10 | 4:56:23 | 5:38:04 | 6:20:52 | 6:56:00 |
| 30-39 | 4:09:58 | 4:43:28 | 5:21:01 | 6:08:17 | 6:47:06 |
| 40-49 | 4:18:08 | 4:42:20 | 5:28:04 | 6:07:32 | 6:56:59 |
| 50-59 | 4:19:42 | 4:57:16 | 5:34:54 | 6:16:05 | 6:52:05 |
| 60-69 | 4:44:40 | 5:18:03 | 5:50:48 | 6:45:48 | 7:06:44 |
To be in the fast 10 per cent as a Singaporean man in your 30s or 40s, you needed to run roughly sub-3:55. That is a lot faster than the overseas charts suggest, because so much of the pack is running in the same heat.
How rare is a sub-4 or a sub-3
Here is the share of each Singaporean group that broke each barrier.
| Group | sub-3:00 | sub-3:30 | sub-4:00 | sub-4:30 | sub-5:00 |
|---|---|---|---|---|---|
| Men 30-39 | 1% | 5% | 14% | 26% | 46% |
| Men 40-49 | 1% | 4% | 14% | 27% | 46% |
| Men 50-59 | 0% | 1% | 8% | 21% | 39% |
| Women 30-39 | 0% | 2% | 6% | 18% | 37% |
| Women 40-49 | 1% | 1% | 8% | 18% | 35% |
Breaking 3 hours is close to mythical here, at 0 to 1 per cent of every age group. Even breaking 4 hours is something only about one in seven Singaporean men in their prime running years managed.
How to move up a bracket
If you want to move from the median into the top quartile, the lever most runners under-use is strength. More running on an under-built body is the fastest way to an injury that ends your block.
Strength training is the most evidence-backed way to reduce running injury, reduced overuse injuries by roughly half, and it improves running economy so you hold pace for less effort late in the race, which is exactly where Singapore's heat breaks people.
That is the side of training we build with runners at Catalyst. Start with personal training for runners in Singapore, or read the main study for the full picture.
Frequently asked questions
Q. What is the average marathon time in Singapore?
The median finisher of the 2025 Singapore marathon took 5 hours 17 minutes. Among Singaporean runners it ranged from about 5 hours 9 minutes for men in their 40s to just under 6 hours for the oldest groups.
Q. What is a good marathon time in Singapore?
Because of the heat, breaking 4 hours puts you well inside the top of your age group, and sub-3:30 is achieved by only a few per cent. To be in the fast 10 per cent of Singaporean men in their 30s or 40s you needed roughly sub-3:55.
Q. Why are Singapore marathon times slower than overseas?
The race runs in December heat and humidity, which slows every runner and hits the second half hardest. It is not a fitness gap, it is conditions, so compare against local times rather than cooler-climate charts.
