One of them, Kayla Davis also locked down a world age group record in the process.
The 13-year-old, who lives in Charlotte, broke the 13-14 world record while at the same time, smashing the United States Track And Field all-time mark in the 400-meter final of the Junior Championships on Sunday. Her time of 52.54 breaks the record of 53.10 set in 2007 by Robin Reynolds.
Davis also won the 200 meters in 23.60 seconds and ran on the third-place 4x100 relay and fifth-place 4x400 relay.
Davis' Run U Xpress teammate Alexander Nunley of Garner turned in another impressive performance bagging three more national titles.
The current national 13-14 age group record holder in the 100-meter hurdles tied a 26-year-old meet record with a time of 12.94 to win his first of the day.
Later he won the 100-meter sprint at 11.23. Nunley had enough gas in the tank to best the field in the 200 meter final, racing home in 24.73.
