The short answer
World Masters Athletics splits competition into 5-year age bands starting at 35 (M35, M40, M45 and so on, same for women). Each band keeps its own world record, ratified by WMA. Records run all the way to M100 and W100. This page indexes the headline marks and explains how the system works.
Key takeaways
- Masters age groups are 5-year bands starting at 35, set on your birthday in a year divisible by 5
- World Masters Athletics ratifies separate world records for every band, men and women, M35 through M100+
- Sprint records decline slowly to about 60, then drop faster each decade
- American (USATF) records are tracked separately and are usually a step behind world marks
- Records are verified here as of 2026 and change often, so always check the WMA list before quoting one
How masters age groups work
Masters athletics divides competitors into 5-year age bands starting at 35. The men's bands are written M35, M40, M45 and so on; women's are W35, W40, W45. You move up on your birthday, in any year that is divisible by five. So an athlete turning 50 enters M50 or W50 on that birthday and competes there until turning 55. World Masters Athletics (WMA), the body designated by World Athletics, ratifies a separate world record for every band, every event, indoors, outdoors, and off the track.
Bands run to age 100 and beyond
WMA keeps ratified world records all the way to M100 and W100. The men's 100m M100 record is 26.34 seconds, set by Lester Wright Sr (USA) in 2022 at age 100.

Two things trip people up. First, the record belongs to the band, not the exact age, so a 53-year-old and a 50-year-old chase the same M50 mark. Second, WMA changes throwing implement weights and hurdle heights by age band, which means a masters record is not directly comparable to the open record set with a heavier implement. We cover that in track implement weights by age and level.
Sprint world records by age, at a glance
The 100m is the cleanest window into age and speed because the event barely changes across the decades. The table below shows the ratified men's and women's 100m world records by band. Read down the column and you can see the decline curve: gentle to about 60, then steeper.

| M/W90 | 16.69 (Hiroo Tanaka) | 21.25 (Emiko Saito) |
Distance running records by age
Endurance ages differently from speed. A masters miler can stay astonishingly close to open form into the 40s, because aerobic capacity and economy hold up better than raw power. Bernard Lagat owns the M35 and M40 mile records at 3:51.38 and 3:54.91, run at ages 36 and 40. Both would have made an open final in many seasons.

| Band | Men | Women |
|---|---|---|
| M/W40 | 3:40.20 | 3:59.78 |
| M/W50 | 3:57.71 | 4:35.40 |
| M/W60 | 4:21.21 | 5:06.65 |
| M/W70 | 4:52.95 | 5:46.9 |
| M/W80 | 5:30.89 | 6:52.77 |
Field events and the implement problem
Throws and jumps add a wrinkle: the implement gets lighter as the band climbs. A man throws a 16 lb shot through M49, then a 6 kg ball in M50, a 5 kg in M60, and so on down. That is deliberate. A lighter implement lets older athletes keep real throwing speed and protects the shoulder and lower back. It also means you cannot compare an M70 distance to an open distance without knowing the weight thrown. The same logic shapes the jumps less, but takeoff power and landing safety still drive how the records fall.
Why masters love video
When you cannot out-muscle the clock, you have to out-technique it. A frame-by-frame look at a block start or a vault plant finds the wasted hundredths that strength training no longer gives back.

World records vs American records
WMA keeps the world list. USATF keeps a separate American masters list, and the two rarely match. The American mark is usually a touch behind the world mark, sometimes by years, because the world record might belong to a Jamaican sprinter or a Spanish distance runner. If you are chasing a record in the United States, the American list is your real target. We break those down in masters track records by age (USATF).
How to read and verify any masters record
Records turn over constantly, especially in the older bands where the population of competitors is small and one exceptional athlete can rewrite a column overnight. Treat any single number as a snapshot. Before you quote a record, confirm it against the live WMA world records page or the Wikipedia list, which cites WMA ratifications and notes marks that are still awaiting approval.
- Confirm the exact band: M55 means 55 to 59, not 55 only.
- Check the venue: indoor, outdoor, and non-stadia records are kept separately.
- For throws, confirm the implement weight used.
- For sprints and hurdles, confirm the wind reading was legal (under +2.0 m/s).
- Note the date, because masters records change fast.
