Maggie MacNeil Drops 4th-Fastest 100 Fly in History at Michigan Intrasquad

Maggie MacNeil, the reigning World Champion in the 100-meter butterfly, threw down a 49.57 100-yard butterfly on Friday at Canham Natatorium in Ann Arbor. Originally scheduled as a tri-meet against Tennessee and Virginia, the meet was reconfigured as an intrasquad competition after Tennessee and Virginia withdrew for safety concerns. MacNeil’s swim, a stunning performance so early in the season, is the fourth-fastest performance in NCAA history. The Michigan sophomore lowered her personal best of 49.59, which had previous been the fourth performance, by .02.

Last October 19, MacNeil went a personal-best 51.49 in the 100 fly while competing in the Michigan vs Northwestern dual meet. A month later at the B1G-ACC Challenge she improved her PB to 50.09. She swam her best time of the season, 49.59, at B1G Championships breaking Big Ten, meet, IU pool, and Michigan team records. Her new time of 49.57 lowers her Big Ten, U-M pool, and Michigan program records.

MacNeil, a sophomore from London, Ontario in Canada, won the 100-meter butterfly title at 2019 FINA World Championships, beating defending Olympic champion Sarah Sjostrom. Her 55.83 set new Commonwealth, Americas and Canadian records.

SwimSwam will cover the full meet at its conclusion.

Wow! A couple of questions…Was she suited up? Was the intrasquad meet saunctioned for records and NCAA qualifying?


Everyone seemed to be suited up by looking at all their results…..similar to Texas’ intrasquad! Wonder if they were making a statement to Uva and Louisville not coming? Or just real rested from being out of their pool for a bit due to water conditions?


Well. She was 55.8 this past summer which is sub 49 yards, so.


UVA and Tennessee




The Michigan team was not rested. Only a few swimmers were ever out of the water because of the parasite. It was business as usual for the team. There are other pools Ann Arbor which they utilized. They were not rested. Just fast.


First really impressive times at this meet. 2nd you are saying a team with an active crypto “infection” among multiple swimmers was using other pools in the community? Hopefully those pools were not in use by others. There is no guaranteed test for this and people don’t have to have obvious symptoms to be shedding it.


So Maggie is looking at a 47 no problem this year and the distance guys should all be way under 4:10 since they were unrested and biz as usual….and lifted that morning!

Go Blue

They cut the training load a little this week and were all suited up.


Everyone was suited up including Maggie


Even the parasites ?


Thankfully no Tennessee swimmers were exposed to this time.


Indeed TN dont not swim in no events where there are open lanes OR endanger athletes with potentially chronic parasitic infection which CAN lead to lifelong health issues OR swim meets without sanctioned officiating. TN is, like UVA, a program of hard working athletes who wait patiently for invites, conference and NCAAs before suiting. Kudos to the Michigan athletes for their hard word, fast swims and for enduring hardship with the pool being closed by the Health Department. A very impressive swim by Maggie in October…will be great seeing her go 48 at NCAAS! Tomorrow the TN and UVA swimmers should have a spirited competition in pure TN mountain spring sipping water!!!! LOL
