Canadian swimming star Summer McIntosh, the world-record holder in the 200m butterfly, will not swim that event at the 2026 Pan Pacific Championships to avoid a clash with the 200m freestyle.

The four-day meet features a condensed schedule, and this marks her Pan Pacs lineup debut since the event last took place in 2018.

British runner Josh Kerr clocked about 3:42 to break the 27-year-old world record in the men’s mile at the London Athletics Meet, a historic feat he dubbed “Project 222.” The triumph, celebrated by Kerr but largely under the radar in the fast-paced sports news cycle, ended Hicham El Guerrouj’s 1999 record and highlighted how swiftly attention moves in modern athletics.
Josh Kerr shattered the mile world record with a 3:42.66 in London, aided by a custom Brooks Hyperion 222 spike and a Project 222 speedsuit designed for four laps at world-record pace; the gear features a rocker-shaped sole, a stiff carbon plate, and titanium pins, all built to sustain maximum cadence with no gear changes and was approved by World Athletics. He shaved more than two seconds from his previous best (3:45.34), beating Yared Nuguse by over three seconds, in a campaign reminiscent of Nike’s Breaking2 efforts.
Washington, DC’s 40-minute Fourth of July show, staged by Pyrotecnico, will light the sky with more than 850,000 fireworks and effects and more than 4,250 pounds of fireworks per minute across three launch areas (Lincoln Memorial Reflecting Pool, West Potomac Park, and the Potomac River). The operation requires 50+ trucks and a crew of at least 75, and, if completed as planned, could break the current world record for the largest fireworks display (held by Iglesia Ni Cristo in the Philippines since 2016) as part of the nation’s 250th birthday celebration.
