ISL All-Time Best Swims For Season One (Women’s Events)

ISL Season One

We’ve compiled a list of the Top 10 swims in each event from what was the inaugural year of the International Swimming League. The league doesn’t seem to be keeping records, so we’ve done it for you instead. These records will be a great reference point ahead of the second season later this year.

Although there are still many details yet to be confirmed, some changes for season 2 have already been announced. One such change is the introduction of ‘Jackpot Times’, which is essentially a point-stealing rule. You can read more about the specifics of the rule here.

In theory, this will put more of an emphasis on times this season. Athletes look to gain extra points (a lot in some cases) by beating their competitors by as big a margin as possible. Swims like Daiya Seto‘s World Record in the 400IM (where he beat his competition by 5 seconds), or Katie Ledecky‘s 400 free which was just 0.14 off the WR, would have been rewarded considerable extra points if this rule had been in play last season.

A 5-week training camp and competition is the revised plan for ISL Season 2, and is reportedly taking place in Budapest, Hungary. Announcements of rosters are expected in early-September. You can read more about the plans here.

  • Minna Atherton stormed to a new World Record in the 100m backstroke during her ISL tenure, as well as being a fraction off (0.02) the record in the 200m. She became the first woman to go sub-55 seconds in the event, touching in 54.89 and taking down Hosszu’s previous mark of 55.03. Of all the huge names to participate in the ISL season 1, nobody was as singularly dominant as Atherton in any given event, holding the top 8 times in the women’s 100 back.
  • Katie Ledecky came within 0.14 of Ariarne Titmus World Record in the 400m free – which the Aussie swimmer set back in 2018. Ledecky did, however, set a new American Record with this swim (3:54.06).
  • Hong Kong’s Siobhan Haughey downed two Asian records in both the 50m breaststroke and her speciality, the 200m freestyle, during her ISL stint for DC Tridents. She first brought the marks down to 30.05 and 1:52.01, respectively, both of which were set at the Naples match. While racing in Maryland she slipped under both those marks to deliver a 29.88 in the 50m brs and 1:51.99 in the 200m freestyle.
  • Breaststroke ace Lilly King delivered an American Record with her 28.90 in the 50m breaststroke. She was the only swimmer to break the 29 mark.
  • Melanie Margalis did the double in the 200IM and 400IM this ISL season, setting new American Records in both events. She set the 200IM record at the 1st match in Indiana (2:04.18) and the other when she raced to victory in the 400IM during the Grand Finale is Las Vegas (4:24.15).

Isn’t that freestyle relay faster than the world record?

The women’s 400 free relay is, that’s correct.

FINA World Records in relays must be set by swimmers of the same country. If that rule wasn’t in place, then every year there would be some kind of “all star relay meet” where the 4 fastest swimmers would get together and swim a relay just to break the World Record and collect on their World Record bonuses.

Unlike FINA’s quibbling about individual World Records set during ISL meets, this one-country rule isn’t related to ISL and has been around for a long time.
