 NXN was formerly a part of the Nike Nationals Series, which included national events for indoor and outdoor track before New Balance became the sole national championship events for track and field.NTN was started in 2004 along with the other two meets in the Nike Nationals Series in order to promote the national circuit for high school competitive running.Because the series is not sanctioned by NFHS, the high school sports governing body, the meet is conducted under normal USATF Open competition rules.
