2026 Speedo Sectionals – Roseville CA
February 26-March 1, 2026 Roseville Aquatics Complex, Roseville, California Short Course Yards (25 yards) Psych Sheets Meet Central Results – “2026 CA NV Speedo Sect @ CCA” Meet MobileIt has almost become routine: every time age-group phenom Luka Mijatovic hits the water, he posts a newsworthy time. Today was no different. And yet, even for Mijatovic, today’s performance was extraordinary. After scaring Maximus Williamson’s NAG in the 400 IM yesterday with a 3:40.14 to kick off Roseville Sectionals, Mijatovic swam his bread and butter event tonight… posting a mind-boggling 4:05.76 in the 500 free.
Mijatovic now ranks as the 3rd-fastest performer in the history of the event, and would rank 1st in the NCAA this season by a long shot. The current NCAA leader is future Longhorn teammate Rex Maurer, who posted a 4:08.46 to win the SEC title.
The 16-year-old Texas commit had a previous personal best of 4:08.57, set at the Pleasanton Seahawks SC Senior Meet back in November. He’s now eclipsed Luke Hobson’s 17-18 NAG record of 4:08.42 as well, and becomes the first ever 18&under swimmer under the 4:08 barrier by over 2 seconds.
When Mijatovic first entered the 15–16 age group, the record stood at 4:15.36, set by Drew Kibler in 2016—he has now lowered that standard by nearly 10 seconds. The Pleasanton Seahawk has wrecked havoc on the NAG record book over the past five years, having now set a total of 21 NAG records. This past summer, he qualified for his first senior international team by finishing as the runner-up in the 400 free at the 2025 U.S. National Championships, where he lowered his own NAG to 3:45.71 . Both swims were also under the current 17-18 NAG record of 3:46.01, set by Ryan Erisman.
