How Marathon Participation Has Changed
👉 Swipe to view full table
| Decade | Trend | Key Change |
|---|---|---|
| 1970s–1980s | First running boom | Marathon participation grew from niche to mainstream. Most finishers were competitive runners with fast times. |
| 1990s–2000s | Second boom | Charity entries, "bucket list" marathons, and first-time runners expanded participation dramatically. |
| 2010s | Tech + accessibility | GPS watches, training apps, and online coaching made preparation accessible to everyone. Average times slowed as more recreational runners joined. |
| 2020–2021 | COVID disruption | Thousands of races cancelled. Virtual events filled some gaps but participation dropped significantly. |
| 2022–present | Strong recovery | Live events returned with record registration. Marathon Majors reporting all-time high demand. |
Average marathon finish times have slowed from ~3:30–3:50 in the 1980s to ~4:20–4:50 today. This isn’t because runners are getting slower — it’s because the field has expanded to include far more recreational runners, walkers, and first-timers. The front of the pack is faster than ever.
Marathon Demographics

| Demographic | Stat |
|---|---|
| Gender split (global) | ~65% men, ~35% women |
| Gender split (US) | ~55% men, ~45% women |
| Largest age group | 40–49 (31%) and 30–39 (31%) |
| Average finisher age | ~40 years old |
| Average men's finish time | ~4:21 |
| Average women's finish time | ~4:48 |
| DNF rate (did not finish) | ~2–5% of starters |
The 40–49 age group is now the largest in marathon running — a shift from the 1990s when 25–34-year-olds dominated. This reflects the growing trend of runners discovering the marathon in midlife, often after building years of fitness through shorter races.
What Does This Mean for You?
If you’ve finished a marathon, you’re in a group that less than 1% of people ever join. If you haven’t, the numbers shouldn’t intimidate you — they should motivate you. Every one of those 1.1 million annual finishers started by running their first kilometre. Most began with shorter distances and built up over months.
The most common path: Couch to 5K → 10K → half marathon → marathon. Each step builds the endurance and confidence for the next. Our beginner marathon training plan covers the final step — a 16-week programme designed for first-timers.
