 An unofficial world record was set today at the Olympic track and field trials in Eugene, Oregon. Sydney McLaughlin-Lovroni beat her previous world record in the 400-meter hurdles. The two-time Olympic gold medalist will be competing next month for the U.S. at the Paris Summer Olympics. Gymnast Simone Biles, meanwhile, qualified for her third Olympic team today.
