There is no single “good” marathon pace for an age. Training history, sex, course, conditions, health, and recent race performance matter more for an individual runner. The table below therefore uses a clearly defined external benchmark: the official 2027 Boston Marathon qualifying standards, converted into average pace.
What an age-based marathon chart can tell you
An age-group chart can provide context and a consistent comparison point. It cannot predict your finish time from age alone. The Boston standards are demanding qualification benchmarks, not population averages and not guaranteed entry times.
The Boston Athletic Association states that the standards use a runner's age on race day. Meeting a standard allows a runner to apply, but does not guarantee acceptance when applications exceed the available field size. Always confirm the current rules on the official B.A.A. qualifying page.
2027 marathon pace chart by age
Times are the official 2027 Boston qualifying standards. Pace conversions are rounded to the nearest second. The B.A.A. publishes the same standard for women and non-binary athletes.
| Age on race day | Men: time | Men: pace /km | Men: pace /mile | Women and non-binary: time | Women and non-binary: pace /km | Women and non-binary: pace /mile |
|---|---|---|---|---|---|---|
| 18–34 | 2:55:00 | 4:09 | 6:40 | 3:25:00 | 4:52 | 7:49 |
| 35–39 | 3:00:00 | 4:16 | 6:52 | 3:30:00 | 4:59 | 8:01 |
| 40–44 | 3:05:00 | 4:23 | 7:03 | 3:35:00 | 5:06 | 8:12 |
| 45–49 | 3:15:00 | 4:37 | 7:26 | 3:45:00 | 5:20 | 8:35 |
| 50–54 | 3:20:00 | 4:44 | 7:38 | 3:50:00 | 5:27 | 8:46 |
| 55–59 | 3:30:00 | 4:59 | 8:01 | 4:00:00 | 5:41 | 9:09 |
| 60–64 | 3:50:00 | 5:27 | 8:46 | 4:20:00 | 6:10 | 9:55 |
| 65–69 | 4:05:00 | 5:48 | 9:21 | 4:35:00 | 6:31 | 10:29 |
| 70–74 | 4:20:00 | 6:10 | 9:55 | 4:50:00 | 6:52 | 11:04 |
| 75–79 | 4:35:00 | 6:31 | 10:29 | 5:05:00 | 7:14 | 11:38 |
| 80 and older | 4:50:00 | 6:52 | 11:04 | 5:20:00 | 7:35 | 12:12 |
Important: these are qualification standards for one race, not recommended training paces, average finish times, or a definition of a successful marathon.
How the pace conversions were calculated
Each standard was converted with the same reproducible calculation:
- Pace per kilometre = total finish-time seconds ÷ 42.195.
- Pace per mile = total finish-time seconds ÷ 26.2188.
- Each result was rounded to the nearest whole second.
For example, 3:30:00 is 12,600 seconds. Dividing by 42.195 gives 298.61 seconds per kilometre, which rounds to 4:59/km.
How to set a realistic marathon goal pace
- Start with a recent race. A properly raced 10K or half marathon provides more useful evidence than age alone.
- Estimate the marathon equivalent. Use the race time predictor, then treat the result as a starting estimate rather than a promise.
- Check marathon preparation. Long-run durability, weekly volume, fueling practice, injury history, heat, elevation, and course profile can all move the realistic target.
- Convert the chosen finish time. Use the pace calculator for exact min/km and min/mile values.
- Plan controlled splits. Use the race splits calculator to avoid an unnecessarily fast opening section.
How age affects marathon performance
Large marathon datasets show that the relationship between age and performance is gradual and varies by performance level. Research using New York City Marathon results found an interaction between age, performance level, and pacing rather than one universal age penalty (Nikolaidis and Knechtle, 2017).
Other longitudinal marathon research found that finish times generally increase with age, with a more substantial decline after age 70, while individual results still vary widely (Leyk et al., 2007). This is why age works better as comparison context than as a stand-alone prediction input.
