Sub-5, sub-4, sub-3 — the marathon hierarchy.
The marathon is the benchmark distance. A "good" time depends heavily on age, gender and training. Here are reference times by level and age — plus Boston-qualifying standards.
Reference times across the four standard skill levels. Sub-4 is the most common goal; sub-3 separates trained amateurs from competitive ones.
| Level | Male | Female | Notes |
|---|---|---|---|
| Beginner | 4:30 – 5:30 | 4:45 – 5:45 | First marathon finishers, run-walk pacing. |
| Intermediate | 3:30 – 4:00 | 4:00 – 4:30 | Has trained 16+ weeks specifically. |
| Advanced | 3:00 – 3:20 | 3:20 – 3:45 | Structured 18-20 week build, sub-1:30 half PR. |
| Elite amateur | 2:30 – 2:50 | 2:50 – 3:10 | Boston-qualifying, podium-eligible amateur. |
Boston Marathon qualifying standards (BQ) are the most-cited reference for "elite amateur" marathon times. To register, you must run faster than your age-gender BQ on a certified course.
| Age | Male BQ | Female BQ |
|---|---|---|
| 18-34 | 3:00:00 | 3:30:00 |
| 35-39 | 3:05:00 | 3:35:00 |
| 40-44 | 3:10:00 | 3:40:00 |
| 45-49 | 3:20:00 | 3:50:00 |
| 50-54 | 3:25:00 | 3:55:00 |
| 55-59 | 3:35:00 | 4:05:00 |
| 60-64 | 3:50:00 | 4:20:00 |
Marathon improvement comes from three things: more weekly volume (target 60-100 km/week for sub-3:30, 80-130 km/week for sub-3), structured speed work (tempo runs and intervals), and long runs (peak 30-35 km). A 16-20 week dedicated build typically drops marathon times by 5-15 minutes for committed amateurs. Race-day pacing is critical — most positive splits come from going out 5-10 sec/km too fast in the first 10K.
Across major events worldwide, the average finisher takes roughly 4:25 for men and 4:55 for women. Median for trained amateurs is around 3:50-4:10.
Yes — sub-4 is the most popular amateur goal and puts you ahead of about 60% of finishers. It corresponds to a 5:41/km pace. Sub-3:30 is solidly above average; sub-3 is competitive amateur territory.
For recreational: sub-4:30. For trained amateurs: sub-3:30. For competitive amateurs: sub-3 or a Boston Qualifier. World records are 2:00:35 (men) and 2:09:56 (women).
Boston requires age- and gender-specific qualifying times on a certified marathon course. Standards toughen every few years; check the table above for current BQs by age group.
