Kim, 15, won the event in a time of 50.39, knocking more than six-tenths of a second off his previous PB to become the fastest 15-year-old in Canadian history.

(In the NAG relay record performance, Kim led off in 51.17.)

Kim overtakes current UCSC teammate Paul Dardis (50.76) for ownership of the #1 time ever for a 15-year-old, taking out his previous PB of 51.05 set in March which stands as the 13-14 NAG record.

In the United States, the only 15-year-olds who have been faster than Kim are Thomas Heilman (49.06), Max Williamson (50.14) and Kaii Winkler (50.24).

Kim won the event by more than two and a half seconds, with Elite Swimming’s Eitan Issakov breaking 53 for the first time to earn the runner-up spot in 52.99.

In the 16-18 age group, CAMO’s Antoine Sauve (50.26) emerged with the gold medal over TSC’s Filip Senc-Samardzic (50.42) and Dardis (50.53), with Sauve and Senc-Samardzic both setting new personal bests.

Competing as exhibition, another CAMO swimmer, 17-year-old Ali Sayed, put up a time of 50.15 in the prelims to break the Quebec Provincial Record in the 15-17 age group.

Pointe-Claire’s Patrick Hussey dropped a sizeable PB to win the 19 & over title in 50.09, topping UCSC’s Stephen Calkins (50.26) and UBC’s Blake Tierney (50.36).

The other big highlight of Thursday’s session came in the 200 backstroke, where Brock’s Madison Kryger followed up her standout performance in the 100 back on Tuesday by dropping another big PB.

Kryger, 14, won the girls’ 13-14 event by more than seven seconds in a time of 2:13.85, knocking off her previous PB of 2:14.80 (set in June at the Mel Zajac International) to move up into second all-time in the 13-14 age group, trailing only Taylor Ruck (2:10.22).

Kryger, whose previous best ranked her sixth in the age group, also broke the Ontario Provincial Record for 14-year-olds with her performance.

The girls’ 15-17 result ended up in a tie, as 17-year-old Katelyn Schroeder of the Langley Olympians Swim Club and 16-year-old Delia Lloyd of Etobicoke producing matching 2:12.24s to share the gold.

Lloyd’s swim moves her up to ninth among 15-16 girls in Canada, having previously been 2:13.30 less than one month ago, while Schroeder also dropped more than a second, having previously been 2:13.63 last April.

On the male side, Cascade’s Parker Deshayes won the 14-15 200 back in a time of 2:05.00, dropping his PB of 2:06.80 to rank seventh all-time among 15-year-olds in Canada.

  • In a razor-thin battle, Winskill Dolphins’ Zachary McLeod dropped five seconds to win the boys’ 14-15 1500 free in a time of 16:04.41, edging out CAMO’s Simon Fonseca (16:04.81).
  • Roc Swimming’s Olivier Risk topped the 16-18 1500 free in 15:41.94, taking off six seconds, while Markham’s Alexander Axon clocked 15:31.58 to win the 19 & over event. Axon owns a PB of 15:26.16 from the 2021 Olympic Trials.

These age group categories like 13-14 or 15-16.Are they not irrelevant in the age of computers.Why not just compare 14 year olds to 14 year olds etc..

For starters national records are 13-14 & 15-17 in Canada. Most provinces have single age provincial records so Kim broke Dardis’s records (Alberta & Club 🦖)
