The Granada High School boys 400-yard freestyle relay team, consisting of two Pleasanton Seahawks swimmers, broke the national public high school record last week by posting a time of 2 minutes, 59 seconds in the event final.
The squad of Nick Silverthorn, Trent Trump, Maxime Rooney and Bryce McLaggan bested the previous national mark, held by Chesterton High in Indiana, by 0.36 seconds.
The record-setting swim took place during the CIF North Coast Section Swimming and Diving Championship Meet in Concord.
Rooney and Silverthorn are also members of the Pleasanton Seahawks. McLaggan and Trump swim for the Livermore Aquacowboys team.
The quartet also took home first-place in the 200-yard medley relay with a time of 1:30:67.
Overall, the Granada High finished second in the boys team competition, trailing only Northgate High School of Walnut Creek. The Amador Valley High boys finished in 13th place, and Foothill High came in 17th.
The Dons girls combined to earn a fourth-place finish in the overall team competition, falling three spots behind first-place San Ramon Valley High of Danville. In other girls results, the Granada team came in 13th place and Foothill in 24th place.
