www.nbcolympics.comI don’t have live access to current feeds right now, but here’s what’s known about recent 100m backstroke world records up to 2024–2025 to anchor you, and I can fetch the very latest if you’d like.
Direct answer
- As of my last update, Regan Smith held the women’s 100m backstroke long course world record (57.13 from the 2024 U.S. Trials, lowering the mark she originally set in 2019). The men’s long course record has been held by Thomas Ceccon (51.60 in 2022) and previously Ryan Murphy (51.75 in 2016) with updates in 2023–2024 potentially reshaping the record depending on the event. If you want the absolute latest, I can look it up and confirm whether a new record has been set recently at a major championships or meet.
What you might want to know
- Recent record holders by event type:
- Long course (50m pool) women: Regan Smith’s 57.x times have been the benchmark since 2019, with 2024 trials confirming the record remains among the fastest ever. If a newer time has been posted, it would be at a major meet like the world championships or Olympic trials. [context: Smith’s 57.13 at the 2024 U.S. Trials is the standout performance historically in this event].[5]
- Long course (50m pool) men: Ceccon’s 51.60 from the 2022 World Championships stood as the record, with Ryan Murphy’s 51.75 from 2016 a previous landmark. While Armstrong and Murphy have pushed back at times, Ceccon’s mark is the most recent official long-course WR in this event as of the 2022 Worlds; any 2023–2024 changes would be at major events..[2][3]
- Short course (25m pool) records are separate and have their own holders, sometimes different from long course, and have seen rapid turnover in recent years.
