La Mirada’s Kayla Han Cracks Tuggle’s 11-12 Girls 400 Free NAG with 4:17.65

At last night’s final of the Speedo Grand Challenge meet in Irvine, La Mirada Armada 12-year-old Kayla Han broke the 11-12 girls National Age Group Record in the 400 freestyle. Taking 4th, Han swam a 4:17.65, shedding 2.87 seconds from her previous best of 4:20.52. The swim broke the previous 11-12 NAG of 4:18.41, which was held by Claire Tuggle. Tuggle, now 16, coincidentally won the race last night in 4:10.71.

Here is a split comparison between Han’s record-breaking swim last night, and Tuggle’s previous NAG in the event:

Split Kayla Han May 2021 Claire Tuggle June 2017
1st 50 29.98 29.33
2nd 50 32.83 33.17
3rd 50 32.36 33.12
4th 50 33.04 33.32
5th 50 32.46 32.63
6th 50 32.78 32.68
7th 50 32.48 32.91
8th 50 31.72 31.25
Final Time 4:17.65 4:18.41

The biggest difference between the two swims is that Han had just one split of 33 seconds, and it was low – 33.04. On the other hand, Tuggle had 3 consecutive splits of 33, and all 3 were slower than Han’s.

Han’s swim was just 0.76 seconds away from the Olympic Trials Wave I cut of 4:16.89, which would have made her the youngest swimmer to qualify for the meet.

With a little bit more of maturity, experience and wisdom I’ve learned to calm down about that kind of predictions. 🙂 Even if I recognize that it’s fun to do.
Back 3 years ago I really thought that Claire Tuggle would be the next freestyle star of US women’s swimming and would already make the team in 2020 in the 4X200 free relay. Let’s wait and see but it’s unlikely to happen for 2021. I was confident about Isabelle Ivey becoming a 200 free star too. Both girls have not developed so far as I expected. Or at least as fast as I expected. It was highly tempting back in 2019 to write that Claire Tuggle swimming 1.58 and… Read more »

Claire’s club team didn’t have pool space for a longer time than most due to local covid restrictions. She’s had some challenges and is persevering. I wouldn’t write her off yet.

So, you are saying that if to average the the quality of your predictions then in 50% of cases you were right. Great! It’s the same wisdom that flipping coin has 😀

There is a true story about famous scientist Stephan Timoshenko who is considered to be the father of engineering mechanics after he immigrated to US in 1922.
Before that he was once assigned to direct the main Russian Imperial observatory. When he met the staff for the first time they proudly informed him that during last few years the quality of their weather predictions dramatically improved from 22% to 35%.
“Then take the opposite of your predictions” – was his response.
Next time when you are guessing about future results of NAG record breakers think of this story. There is something in it. 😀
Don’t take any offence. Your comments are always entertaining if they are… Read more »

She’s off to a great start and a great start is a better start than a poor one. These media reports don’t define a person, they’re just blips on her journey.

on a less upbeat note, it’s hard not to notice how little Claire improved in 4 years. I don’t think 400 free is her best event, I wish her big drops. Regardless, downvotes are deserved

Would be fun if she swam it again and went for the Wave 1 cut this weekend!
