How records work

Records are set under a sanctioning body's rules — set, judging, and equipment all matter. A lift in your garage counts for you; a lift on the platform counts for the books. Each entry here is owned by the body that published it, shown by its badge and footnote.

Chasing a mark?

Records are set at sanctioned contests. Once a meet's results are posted to the owning body's database, new marks show up here at the next sync. Spot an error? Let us know.
