Get ready to be blown away by the future of swimming! The Roseville Sectionals just witnessed a jaw-dropping performance that’s setting the swimming world abuzz. Luka Mijatovic, the 15-year-old phenom and national team standout, kicked off the 2026 Speedo Sectionals in Roseville, California, with a lifetime best in the 400 IM, clocking an incredible 3:40.14. But here’s where it gets even more thrilling: this time puts him just a hair’s breadth—less than half a second—from Maximus Williamson’s 2022 National Age Group (NAG) record of 3:39.83. And this is the part most people miss: Mijatovic achieved this feat after already dominating the 200 free earlier in the evening, showcasing his versatility and endurance.
Held from February 26 to March 1, 2026, at the Roseville Aquatics Complex, this short course yards (25 yards) event has been a hotbed of talent. Mijatovic, a Texas commit, split his 400 IM race with precision: 50.26, 56.31, 1:03.50, and 50.07, finishing a full ten seconds ahead of the competition. This performance not only shattered his previous personal best of 3:40.96 (already the #2 all-time in his age group) but also solidified his status as a rising star. His 200 free time of 1:33.27, just shy of his personal best of 1:32.73 from last December, further underscores his dominance. Yet, Thomas Heilman’s 15-16 NAG record of 1:32.46 remains just out of reach—for now.
But here’s where it gets controversial: With Mijatovic’s rapid progression, is it only a matter of time before he claims multiple NAG records? Or will the pressure of expectations slow his momentum? Let’s dive into the discussion in the comments!
The girls’ competition was equally electrifying. Fourteen-year-old Lauren Lonsdale of Sacramento Aquatics delivered a breakout performance, winning the 200 free in 1:46.49—a massive improvement on her previous best of 1:48.26. This time catapulted her to #2 among 13-14 girls this season. But she didn’t stop there. Lonsdale followed up with a 4:12.62 in the 400 IM, a seven-second drop from just two months ago, securing her #3 spot nationally in her age group. Her double victory is a testament to her potential as a future powerhouse in the sport.
Another standout was 13-year-old Ayden Tan of San Ramon Valley Aquatics, who stunned everyone by winning the 50 back against a field of high schoolers with a time of 22.94. This marked Tan’s first sub-23 swim and placed him over a second ahead of the next-fastest 13-year-old backstroker in 2025-2026, Jett Hatchard (24.29). Tan’s performance is a clear sign that he’s one to watch in the coming years.
As the Roseville Sectionals continue to unfold, one thing is certain: the future of swimming is brighter than ever.
