If the 3 World Records, 15 Championship Records, and 28 Continental Records set during the World Aquatics Championships – Singapore 2025 were the encore, the age-defying performances of the World Masters Championships swimmers delivered even more.

The Singapore Masters resulted in a rewriting of the record books, with 31 Masters World Records and 129 Masters Championship Records set over seven competition days from August 7 to 14.  The only days World and Championships records didn’t fall were on August 9th – Singapore’s 60th anniversary – a competition-free day to celebrate the island nation’s history.

Of the 31 Masters World Records set in Singapore, 14 were by women, 12 by men, and 4 in relays (3 men’s relays and 1 mixed). This is 10 more long-course swimming World Records than were set in 2024 at the previous edition of the World Aquatics Masters Championships in Doha, Qatar.

Neutral Athlete Mikhail Vekovishchev was one of the standout performers in Singapore, swimming the Men's 50 Butterfly in 23.15 for a pending Masters World Record in the Men's 25-29 Category, a time that would have placed him 15th in the same race of the semifinals at the elite 2025 World Aquatics Championships in Singapore.

For the latest Masters World Records, check out the long course (50m pool) list here and the short course (25m pool) list here. Relay records in the long course pool can be found here, and the short course list is available here. Please note that the ratification process takes a minimum of 30 days, so some records set in Singapore may still be pending official approval.
