The new Ultimate Championship, billed as a fresh format for athletics, kicked off with pole vault star Armand Duplantis once again taking center stage and winning. Britain's Keely Hodgkinson also advanced, cruising into the 800m final after topping her semifinal, a race marred by incident. The anticipated men's 1500m showdown between Jakob Ingebrigtsen and Josh Kerr will not take place after Ingebrigtsen withdrew from the final, putting the rivals' reunion on hold and altering one of the meet's most hyped matchups.
