Harvard capped off a strong finals session on Day 3 of the 2026 Ivy League Women’s Swimming and Diving Championships with a new Ivy League, meet, pool, and school record in the 400 medley relay.
The quartet of Anya Mostek, Aliana Marakovic, Sydney Lu, and Blythe Wieclawek combined for 3:32.44 to eclipse the mark that their Harvard predecessors, Felicia Pasadyn, Jaycee Yegher, Miki Dahlke, and Kennidy Quist, had set in 2020.
Mostek, who had won the 100 back for the fourth consecutive time earlier in the session, started things off with a 51.45 backstroke leadoff. That is only the second time in history, after her 51.31 performance in tonight’s individual event, that an Ivy League swimmer has broken the 52-second barrier. Mostek put Harvard out front by a full second over second-place Penn.
Marakovic took over and split a 1:00.73 to give the Crimson an even larger lead over the rest of the field. She had finished 5th in the individual event with 1:01.72.
Next up was Lu, who had started Day 3 with a big win in the 100 fly individual final, clocking a 51.97 to finish a full second ahead of the runner-up. Lu went 52.15 on the third leg and increased Harvard’s lead to 2.95 seconds over Penn.
Wieclawek, who had competed in the 100 back and finished 8th with 54.79, anchored the relay with 48.11, pulling Harvard further ahead of the field to win by 3.23 seconds.
The quartet took .28 off the Ivy League and Ivy meet record, which was also the Harvard program record. Here are the comparative splits:
| Harvard 2020 | Harvard 2026 | |
| Backstroke | Felicia Pasadyn, 53.41 | Anya Mostek, 51.45 |
| Breaststroke | Jaycee Yegher, 58.70 | Aliana Marakovic, 1:00.73 |
