Katie Kubiak, Koehn Boyd Open Paralympic National Championships with World Records
Katie Kubiak and Koehn Boyd began the 2025 U.S. Paralympics Swimming National Championships with world records on Friday.
Kubiak twice lowered the world record in the women’s S4 50 butterfly. The 22-year-old from Cedarburg, Wisconsin, clocked in at 39.66 seconds in the morning prelims. That erased the record of 40.22 seconds set by Spain’s Marta Fernandez Infante at the 2021 Tokyo Paralympics.
Kubiak went lower still at night, breaking 39 seconds with a time of 38.96. She also won the women’s S4 50 backstroke in 42.14 seconds.
Elsewhere on the first day of swimming action in the three-day meet at Idaho Central Aquatic Center in Boise, Boyd opened the morning with a world record in the SM10 400 individual medley. He went 4:45.83 in prelims, taking down the mark held since 2014 by American Ian Silverman at 4:53.24.
Boyd, 16, also won the S10 400 freestyle in 4:08.99, his winning margin some 40 seconds, and the S10 100 fly in 57.85, as the only swimmer in his class to break a minute.
Gray Rutledge lowered her American record in the S2 50 back with a time of 1:07.78, four seconds faster than her previous mark. She was second to Kubiak in the event, with all events swim in multi-class format and winners determined by World Para Swimming points.
Summer Schmit won the multi-class women’s 400 free, the S9 swimming clocking in at 5:01.28.
Boyd was the winner in the men’s 400 free. Second was Noah Jaffe, the S8 swimmer going 4:41.67.
Liz Smith won the S9 100 fly, her time of 1:10.88 the best of five competitors. Taylor Winnett won the S10 race in 1:10.73, while Abby Kershaw bested Piper Sadowski by a half-second in the S14 race.
Paralympic gold medalist Ellie Marks set a quick time in the S6 50 fly of 41.03, the 34-year-old the only competitor in her class.
