What Is a Good Marathon Time? Averages by Age, Sex, and Experience

Last updated: May 2026

The average marathon finish time worldwide is approximately 4:29:53 — but that number on its own tells you very little. Whether a given time is “good” depends on your age, sex, training history, and what you’re comparing yourself against. This article breaks down marathon finish time averages across every population group so you can set a realistic and meaningful target.

Global Average Marathon Finish Times

Two large datasets give the most reliable global benchmarks:

A second dataset from MarathonHandbook, covering 35 million race results, reports slightly faster medians: 3:48:20 overall, 3:34:56 for men, and 4:08:09 for women. The difference reflects sample composition — larger datasets that include major city marathons tend to skew toward more competitive, higher-trained fields.

Good Marathon Times by Experience Level

Sub-4:00 is the most commonly cited personal milestone in recreational marathon running and represents roughly the top 40–45% of all finishers globally. Sub-3:30 is a meaningful benchmark that signals consistent training and race-specific preparation. Sub-3:00 requires years of focused work and places you in the top 5–8% of all marathon finishers.

Marathon Times by Age Group

Men

Women

Performance peaks in the 18–34 age bracket and declines gradually through each subsequent decade. The decline rate accelerates noticeably after 55, driven by reductions in VO2 max, muscle mass, and running economy. That said, experienced masters runners often outperform their age-predicted times significantly.

Boston Qualifying Standards

Boston Athletic Association qualifying times are widely used as a performance benchmark because they represent a meaningful, externally defined standard:

Note that meeting the BQ standard is no longer sufficient on its own — in recent years the actual cut-off for acceptance has been 2–6 minutes faster than the qualifying standard due to oversubscription. The standards above are the minimum threshold, not the guaranteed entry time.

World Records

For context, the current marathon world records are:

• Men: 2:00:35 — Kelvin Kiptum (Chicago Marathon, 2023)
• Women: 2:09:56 — Ruth Chepngetich (Chicago Marathon, 2024)

These times represent the outer boundary of human performance under optimal conditions: elite genetics, years of professional training, ideal weather, flat course, pacing support, and advanced footwear technology.

What Is a Good Time for You?

The most useful benchmark is not the global average but your own predicted time based on recent race performance. If you have a recent 5K or 10K result, the Riegel formula gives a reliable estimate of what your current fitness translates to at marathon distance — factoring in pace degradation across the full 26.2 miles.
