Kaitlyn Dobler, a senior at Beaverton, Oregon’s Aloha High School, took down the Girls’ National Public High School Record in the 100-yard breaststroke on Saturday, swimming a 58.35 in finals at the Oregon 6A State Championships.
Dobler clocked a 58.75 in prelims to break the 59-second barrier for the first time and come within .35 of Emily Weiss’s National Public High School Record from 2018. In finals, she went out 3/10 faster and came home 1/10 faster, giving her a .05 edge on Weiss. See the comparative splits below:
