Boys 400m Dash
One event that could see the national record fall is certainly this boys 400m dash. The current record is 46.01 or 45.92 if you count record at altitude. Leading the way for the field is Justin Braun of Ohio who owns a personal best of 46.77 indoors and 46.76 outdoors (2019). With competition, which he will have, the winner should be able to break 46.
