The Miami Gardens Xpress 12-year-old boys 4x800m relay won in 9:24.6, just five seconds outside of their own AAU National Championships record of 9:19.92, set one year ago.

Interview of the Day:

The Track Minnesota Elite women's 17-18 4x800m relay overtook hometown favorites and early leaders Motor City TC on the third leg and held on for the win, 9:23.39 to 9:35.61, to defend their AAU national title in convincing fashion.
