Summer McIntosh Swims Eighth-Fastest Time Ever in 400 IM at Longhorn Elite Invite; Regan Smith Breaks 56 in 100 Fly<\/strong><\/p>\n

No single swimmer has dominated an event in recent years like\u00a0Summer McIntosh<\/strong> has in the women’s 400 individual medley. McIntosh is the Olympic champion and three-time world champion in the event, with a world record of 4:23.65 sitting almost three seconds ahead of any other swimmer in history. In a Friday evening race at her training base in Austin, Texas, McIntosh fired off a stellar 400 IM performance quicker than any other active swimmer has ever recorded.<\/p>\n

At the Longhorn Elite Invite, McIntosh swam a time of 4:27.31, which ranks as the eighth-quickest effort ever recorded. McIntosh has six of the seven quicker times, with Katinka Hosszu<\/strong> the only other swimmer to achieve a faster time. The next-best active swimmer is\u00a0Kaylee McKeown<\/strong>, who owns a best time of 4:28.22. In a noncompetitive midseason meet, where no one else swam under 5:00, McIntosh swam an incredible six seconds faster than the silver-medal-winning time from last year’s World Championships.<\/p>\n

The other top performance Friday came from\u00a0Regan Smith<\/strong>, another member of\u00a0Bob Bowman’s<\/strong> pro group based at the University of Texas. Smith won the women’s 100 butterfly in 55.94. That made her the second swimmer to swim sub-56 this season, with only world-record holder\u00a0Gretchen Walsh<\/strong> faster. Smith surpassed her previous season-best of 56.18 and was close to her best time of 55.62, which ranks No. 5 all-time. Smith has never raced the event at an international competition, but this time is quicker than the bronze-medal mark from last year’s World Championships.<\/p>\n
