On the last night of the 2023 Florida Gold Coast Senior Championships, 16-year-old Kaii Winkler threw down the first sub-42 100 freestyle done by a 15-16 year-old. Winkler lowered his own National Age Group (NAG) record by two-tenths to clock a final time of 41.96.

All-Time Top Performers, Boys’ 100 Free, U.S. 15-16 Age Group

  1. Kaii Winkler – 41.96 (2023)
  2. Maximus Williamson – 42.49 (2022)
  3. Thomas Heilman – 42.61 (2023)
  4. Ryan Hoffer – 42.67 (2014)
  5. Jack Alexy – 42.87 (2019)

Winkler’s previous best time stood at 42.21, which he swam at Winter Juniors – East this past December. He initially broke Ryan Hoffer‘s record in November at the 2022 Florida High School State Championships, where he clocked a 42.52 to take three tenths off Hoffer’s time. His racing strategy between December and now hasn’t really changed, as both his opening and closing 50 splits were faster than they were in December.

Split Comparison:

Kaii Winkler, 2023 Florida Gold Coast SCY Senior Championships Kaii Winkler, 2022 Speedo Winter Juniors – East Kaii Winkler, 2022 Florida 1A High School State
50 20.10 20.22 20.57
100 41.96 (21.86) 42.21 (21.99) 42.52 (21.95)

This race caps off a highly successful weekend for Winkler. In addition to the 100 free, Winkler recorded personal best times in the 200 free (1:33.28), 100 fly (46.94), 50 free (19.44), and 500 free (4:23.85). His 200 freestyle time moved him to #2 all-time in the 15-16 age group, while his 50 free puts him at 3rd. His 500 was notably a 16-second drop, with his previous best time standing at 4;40.18 from 2021.

This long & lean body type always seems to make people comment about how much improvement will happen when weight training starts. Suggesting that the bulkier Nathan Adrian body type is the ideal. I’m beginning to wonder if this leanness is a few talented individuals or the new norm?

this is his potential. Thin and tall, already swimming so fast, adding strength will only make it faster
of course need add strength smart.

Diehl will go pro. IU pro group is probably the destination.

They’ve got a couple of breaststrokers and a masters swimmer who makes vlogs. Only places with considerable number of pros these days are Florida and ASU.

And that’s not even counting the 17-18 YOs like Buff and Mcfadden and Diehl

He’s been dropping a lot of time this year in both long course and short course. Got to think a relay spot on the national team this summer could be possible.

Olympics gold in Paris, at the same age as Chalmers was in Rio.

Lol I think Popovici has that gold more than secure next year but 2028 could be a battle between these two although this is wayyy too early for that prediction.

Imagine this:

the Slim Reaper vs the Skinny Legend. Might be one sided now but in the not too far away future it could be a battle between the two.
