Lydia Jacoby Drops 2:24.03 200 Breast For Massive Two-Second Best Time


Lydia Jacoby‘s run of good form continued on Thursday on the second day of the Mare Nostrum Tour stop in Barcelona, as the 19-year-old American delivered a significant best time en route to victory in the women’s 200 breaststroke.

Jacoby, who swam her fastest time since winning 2021 Olympic gold in the 100 breast on the opening day of the meet, dropped nearly two seconds in the 200 breast on Day 2, clocking 2:24.03 to earn a come-from-behind win.

Jacoby’s previous best time stood at 2:25.98, set at the Monaco leg of the 2022 Mare Nostrum Tour last May.

The biggest difference between the two swims was Jacoby’s aggression on the second 50, though she was quicker on every split:

Split Comparison

Jacoby, 2022 Mare Nostrum – Monaco Jacoby, 2023 Mare Nostrum – Barcelona
33.14 32.77
1:10.88 (37.74) 1:09.65 (36.88)
1:48.87 (37.99) 1:47.23 (37.58)
2:25.98 (37.11) 2:24.03 (36.80)

She charged to victory in Barcelona thanks to her blistering closing 50, having run down Denmark’s Thea Blomsterberg (2:24.50), who was nearly nine-tenths ahead at the final turn.

Jacoby’s previous PB from Monaco last year came one month after the U.S. International Team Trials, where she missed a spot on the 2022 World Championship team after her stunning Olympic gold medal victory in Tokyo.

While failing to earn a spot on the Worlds team was certainly a setback for the Seward, Alaska native, she has been on fire ever since.

Jacoby reached a new level in the short course pool during her freshman year at the University of Texas, setting new National Age Group Records for 17-18 girls in both the 100-yard (57.29) and 200-yard breast events (2:04.32), finishing things off by winning the NCAA title in the 100 breast.

Already a major threat to earn an individual spot at the 2023 World Championships in the women’s 100 breast at U.S. Nationals next month, having placed fourth last year behind Lilly KingAnnie Lazor and Kaitlyn Dobler, Jacoby’s 2:24.0 performance puts her in the conversation in the 200 breast as well.

However, she’ll probably need to continue her progression in order to truly challenge for a spot, as the U.S. had three of the four-fastest swimmers in the world last year: King (2:21.19), Kate Douglass (2:21.43) and Lazor (2:21.91).

Funny people downvoting this, but then McKeown is not even the fastest in her family over 200m Breast!

They’re downvoting it because this same user posts “quicker than X Australian” on literally every single article. They are obsessed and clearly have some kind of mental issue.

McKeown isn’t a breaststroker. It’s like if I posted “quicker than Annie Lazor in the 400 free” on every article about Titmus.

Lilly King better watch her back in the W 200 BR. First, Douglass. Second, Jacoby.

Lydia looks so much stronger physically in photos now versus before she went to Texas. Cool to see how weight training in college is paying off. She’s a beast.

Who could have guessed that swinging more than the 2500-3k or workout she got through high school would help her 200? They had her absolutely prepared for a 100, but obviously needed more for this event.

That was unexpected after the 2023 NCAA Division I Women’s Swimming and Diving Championships.

Her 200 was a little disappointing at NCs. She had gone a lot faster at other points in the season. She bounced back though, no big.
