The all-time USMS Top 10 is the list of the ten fastest times ever recorded in U.S. Masters Swimming for each event, age group, sex, and course. Openlane aggregates every published Top 10 since USMS began tracking national rankings and renders the result as one searchable table.
Use the filters to choose a sex and age group; all standard events appear across Short Course Yards (SCY), Short Course Meters (SCM), and Long Course Meters (LCM). The default view below shows women 45-49 SCY for representative events.
Openlane is an independent analytics project and is not affiliated with, endorsed by, or operated by U.S. Masters Swimming.
