Blueseventy Swim the the Week: Ledecky Beats Hosszu’s IM Record


Disclaimer: BlueSeventy Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The BlueSeventy Swim is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.

For the second-straight year, Katie Ledecky gave up a freestyle race to swim the 400 IM at the Pac-12 Championships, and for the second-straight year, she came up with a big national record.

In 2017, it was the American record, with a 3:57.68 that ranked behind only Katinka Hosszu in the historical ranks. In 2018, Ledecky knocked off Hosszu with a 3:56.53.

This time around, she won’t have to watch that record get taken down by a teammate while she swims different events at NCAAs. Ledecky will swim the 400 IM next month, setting up what could be an even bigger swim for the Olympic and world champ.

Here’s a splits comparison of the two:

Ledecky 2018 Hosszu 2012
Fly 54.75 25.90 25.47 54.71 Fly
28.85 29.24
Back 59.29 30.34 30.36 59.84 Back
28.95 29.48
Breast 1:09.43 34.61 34.53 1:08.41 Breast
34.82 33.88
Free 53.06 27.08 27.10 53.58 Free
25.98 26.48
3:56.53 3:56.54

How swimming is every part of what makes you tick. Aptly named because 70% of the earth is covered in water, blueseventy is a world leader in the pool and open water. Since 1993, we design, test, refine and craft products using superior materials and revolutionary details that equate to comfort, freedom from restriction and ultimately a competitive advantage in the water.

Wow. Ledecky is phenomenal.

So Hosszu starts half a second ahead at the 50, Ledecky catches back up and stays even through 150, pulls ahead by 200. Hosszu retakes the lead on breaststroke by over half a second again, maintains that advantage through the first 50 of free, and then gets run down and out-touched in the last 50. That would be an insane race

Katinka is far better in back and breast than she was in 2012.

When she made her 4:26 in Rio (2016) it was 5 sec improvement (from gold race in Kazan 2015) coming from breast and free legs. There were no noticeable progress in her signature strokes since 2012 in 400IM

There were. Look at her PBs in back and breast and not in IM. BTW please don’t compare a first and a last day swim.
